In our previous article where we discussed the mind-boggling complexity of our eyes’ retinas. We learned about the ten separate layers of cells, but we did not elaborate on the intricacies of their creation. We also learned how the substance in the cone cells, called rhodopsin, is destroyed on exposure to light and then regenerated in the dark. We thus touched on the wisdom behind the existence of both night and day.

The destruction of rhodopsin is caused by the generation of electricity after its contact with light. This electric impulse is transmitted from cones and rods to either horizontal or bipolar (having two poles) cells. The section between these two different layers of cells is called the outer plexiform layer, where horizontal cells receive electric impulses from rods and cones, and carry them to neighboring bipolar cells. The horizontal cells are also charged with transmitting electricity horizontally between rod and cone cells. The signals make it possible for shapes to be carried to the central nervous system in an appropriate contrast. Other signals are blocked so that the borders of the place of contact with light can be clarified in the brain, which does not receive an excessive load of signals. If it were not for these cells, it would be harder to perceive borders because the line of difference between two different colors would not become clear.

Bipolar cells have two opposite poles. They are created as one of two types, in accordance with their functions: one amplifies generated electric impulses, while the other inhibits the transmission of excessive impulses from around the perceived object to the brain. Bipolar cells provide the contrast necessary for making borders clear. They make clear vision possible, and yet most people have never heard of this wondrous gift inside their retinas!

How is contrast enabled?

Thanks to an innate ability, our brain does not occupy itself with regions that have the same color or the same light. It will not be stimulated much if, for example, a wall is completely white or a car is bright red all over. If, however, there are other colors on the wall, say, a white moon or star on a red background, then there will be more stimulation in the brain. Suppose we place the shape of a crescent on the wall. The stimulated parts of the brain will lie along the sharp ends of the crescent, not in the inside or outside of it. The stimulation in the brain is less associated with non-contrasting regions than contrasts in view. The higher the contrast, i.e. the greater the difference between light and dark areas, the greater the degree of stimulation.

Amacrine cells in the inner plexiform layer of the retina enable horizontal transmission. There are up to 30 different types of these cells, and they carry out at least five to six functions. For instance, one type of Amacrine cell transmits electric impulses from cones and rods to bipolar cells, then to other Amacrine cells, then to ganglion cells, and finally to the brain.

Another type of Amacrine cell responds strongly to the onset of the visual signal, while another to its completion. One other type reveals the difference in light intensity regardless of direction, while still others respond to the movement of a light point in a certain direction in the retina, causing a perception in the brain as to the direction of the light.

Further research may reveal yet more functions. Amacrine cells might have such functions as regulating the intensity of electric impulses specific to each wavelength and generating different levels of impulses for moving or stationary objects.

The function of the ganglion cells in the innermost layer of the retina is to help ensure that the electric impulse generated and corrected in the retina is eventually transmitted to the brain. Three distinct ganglion cells are identified in the retina. These cells are represented with the letters W, X, and Y. W cells are assigned the task of transmitting signals from rod cells, which produce black and white visual signals in the dark. Making up about 40 percent of all ganglion cells, they have diameters of less than 10 micrometers and transmit signals at a speed of 8 m/sec. It is evident that these cells are assigned the task of perceiving objects in the dark as rough, vague shapes.

X cells, on the other hand, transmit electric impulses to the brain, creating precise color pictures of objects. Making up 55 percent of ganglion cells, they have midsize diameters (10-15 micrometers) and transmit signals at a speed of 14 m/sec.

The largest of ganglion cells (with diameters as long as 35 micrometers), Y cells are assigned the task of transmitting instant changes in sight. Making up only 5 percent of ganglion cells, they send signals at speeds of 50 m/sec.

Sending intense signals in split seconds, Y cells inform the central nervous system immediately in case of a threat or an unusual encounter. When our body or eyes face a threat, these cells help protect us by warning the brain to move away from the threat or close our eyelids rapidly. If it were not for these cells, we would not be able to reflexively close our eyes and thus protect them. It’s incredible to ponder how complex these systems are – and how perfectly they’ve been created.

Between layers of cells there also lie layers of network that house neurons and their connections (synapses). These cells too have subgroups trained to carry out specific tasks. All of these cells are built according to certain specifications so that they can transmit stimuli to the brain when they receive light. Extremely severe visual problems develop when even a single layer of these types of cells is missing. Every one of the layers in our eyes is immensely special, and it is hard to imagine them to have been randomly placed there. It should be born in mind that this article simply skipped numerous elements of the retina and their chemical functions. Taking the precise measurements and mechanisms into account, we can only feel greater awe and love in the face of the incredible art devoted to the creation.

Knowing oneself is a good starting point. But what does it mean, after all? Is it possible to know yourself at all, particularly with all the tools we are presented with or forced to acquire throughout our lives? Tools, after all, are all limited in nature, presented to you by others, such as language skills, thought processes, and cognitive abilities. Then, do you think you can know yourself, let alone develop your own philosophy of life? With all these difficulties, you set out on one of two differing paths, either one where you become a thinker yourself and be a lighthouse yourself, or another, where you just drift around another lighthouse. Anything beyond could be darkness. The difference between these two seems to lie in asking, seeking, and questioning; that is, in having an inquisitive mind versus embracing, accepting, and believing – in other words, having a submissive mind. It becomes more like choosing a blue pill versus a red one, as is depicted in a recent film, which is a rather successful strategy for guiding the submissive in searching for meaning.

With all these thoughts, let me begin to talk about my journey of seeking the meaning of life – well, in particular my life. With all the boundaries and veils around me set by education and indoctrination, I set sail into different waters, far away. I enjoyed being myself as a subject rather than an object. I freed myself of some knowledge without any facts and was bound by other knowledge. This painstaking unweaving and weaving of myself led me to being who I am now, with numerous toolsets of scientific facts and knowledge, of faith and truths, with numerous veils, some old and some new. And I am somewhat content with what I have now, albeit at times I fear missing the whole point that is the meaning of life. Then, I revert to my comfort zone and feel safer for the moment.

Again, with all the new adventures and relearning of myself, I find myself mostly looking for contentment with life – both my life and others. Contentment, superficially a head-to-toe feeling, gives me a sense of safety and the courage to seek more facts and knowledge in science and faith. Confusion, on the other hand, is my fear. The difference is like having 20/20 vision versus having serious cataracts. In my journey, the beam of a lighthouse illuminated me and made me feel that I have 20/20 vision, by which I can potentially see and get to know everything and be contented with everything, most importantly with myself. But was this just due to this lighthouse or had I developed the tools to be my own lighthouse? With the comfort of not having to probe this question, I preferred to drift near this lighthouse all the time.

Reaching a comfort zone around this luminous lighthouse, and in my contentment, I stalled in searching myself for a while. Each and every time I attempted to sail a little further, I quit, fearful that I could go no further. I then realized that there were many more artifacts around this lighthouse that could help me develop my own tools for my journey. They were quite marvelous and beautiful artifacts. They were also quite handy, as if they were made for my use. I tremendously enjoyed collecting these objects, and sort of built my own little ship under a little projector. And, as if there must always be a catch, some of these artifacts were reflective in nature, and when I looked at them, I saw my own dark side. This soured my enjoyment for seeking and collecting ornaments. As if this was not enough of a sore point in my journey, I got to see others’ dark sides as well, which caused me even further pain. A dualism of saying and doing in many led me to become more cautious, as I tried to shed light into my dark sides. After all, terrible things could happen in the dark. As I enjoyed the moments under the lighthouse, despite the possibility of darkness, I learned that there were also other artifacts that could help me with my dark side and my dealing with others’ darkness. Through formulating and solving these problems, I was delighted to find that these artifacts were even more beautiful than when I thought when I saw them for the first time. Along with these ornaments, I also got to meet some great adventurers just like me, with the same hopes and problems and also with helping hands. I became even more content with what I had at the time.

As time passed, I encountered another obstacle in my journey; I lost my passion for the search. I felt too overwhelmed with the almost constant dualism of saying and doing and tended to lose my patience with the darkness in others and partly in myself. This was too much to take. Was there another artifact around to help me through this obstacle? In search of this “yet to be found” artifact, I again partly got into the process of unweaving and weaving myself. While moving through this stage, I got to see that finding more and more objects could cause someone to become quite pretentious and full of false hope. This newly found “fact” saddened me quite deeply.

Not to be trapped in these obstacles, I needed to put more effort into finding more around me to help me proceed. But it was not easier. On the contrary, it was a lot more difficult. This led me to another “fact”: whatever I was searching for could be only found by someone who persists. I got to see that knowing and doing are quite different, just as saying and doing are different from each other. Nevertheless, I grew more curious about what might come, let it be other precise substances or quasi-unyielding obstacles. Maybe this seek, jump, and find makes the trip joyful and worthwhile.

Where am I right now? With more artifacts and greater contentment with what I have and who I am, I am now more eager to set sail further under the luminous light of this breathtaking lighthouse, full of passion and joy, seeking to see what is to come. Have I developed any sense of knowledge or belief, or a motto for my life? Well, I am at a point right now where I know by heart that there are beautiful objects and ornaments and flowers in the Garden of Eden. They are only visible in the light, and I am much contented that I found a beautiful lighthouse that continuously sheds light on the Garden. I am undecided yet whether I can sail further or stay around in my current contentment.

When I look back, I see that throughout my joyful journey, I tried to keep an inquisitive mind and learn about my dark side while discovering that there are more things waiting to be found and healed. I also learned that being pretentious and contentious is a big obstacle to gaining consciousness in finding the good in life. I also got to see that while seeking, finding, being helped and helping others – sailing, in other words – the whole journey is full of action and reading. Reading myself, others, and all these artifacts, reading the beautiful writing on this beautiful lighthouse was what I was doing all along. This reading and doing made the journey of life actually very rewarding in itself. I now treasure the artifact I get to develop throughout my journey – sometimes alone, but mostly under the light of the lighthouse I came across. I have a strong knowledge of and belief in this artifact. It gives me passion and conscience throughout my journey of life, through which I sometimes walk alone, but mostly with others. It sheds light when I see darkness in myself and in others. It helps me find more precious artifacts and develop even more of them along the way. It helps me find joy even among obstacles. It gives me passion and hope for getting ready to sail away into unseen waters that will take me among the endless artifacts under the light without any darkness. Then, I will say I am more than content and thankful for this great fulfilling journey.

To find a way out

Toward that which it seeks and longs for

Travels with the hope of recovering what is lost

Travels from the reason to the heart

To bereft of power

To distinguish the hopeful

from among the hopeless causes

There’s a cold war between realities and imaginings

Dawn comes in dreams

When everything turns pale in the dead hours of the night

Dawn comes in dreams

Dreams are always vivid

Full of color

There when a man looks deep

Into unfathomed oceans

Beholds the past

The far future and what is near to come

What is old about to be replaced or renewed?

Dawn comes in dreams

When realities are too dark to endure

Dawn comes in dreams

In darkness a man suffers

The extreme of loneliness

When mouths are tight-lipped

As if zip-fastened

He wishes to sprout wings and fly

To the realms beyond and fly

Dawn comes in dreams

When events begin to drive me to give up hope

Dawn comes in dreams

We have had to deal with tests and exams in academic and professional life from childhood on. Though we are motivated to perform our best, the pressure-filled situations generally cause us to perform below our abilities. University of Chicago researchers were interested in finding an intervention that would improve performance under such conditions, especially for those students who do not do well on exams because they are blocked by anxiety. Their study showed that simply writing down our thoughts and concerns immediately before a high-stress event can increase performance from 5–12 percent when it matters most. The simple brain-focusing exercise of writing down feelings for ten minutes before an exam reduces anxiety and increases exam scores significantly. The researchers concluded that writing allows individuals to reexamine the situation and revaluate concerns, reducing anxiety and increasing one’s ability to focus. This type of writing may help people perform their best not only on tests but also in variety of high-stress situations—a big presentation to a client, a speech to an audience, or even a job interview.

2- Life Without Starlight

Original Article: Hooper, D. & Steffen, J.H. (arXiv:1103.5086v1).

Liquid water is considered the common solvent to catalyze carbon-based life on planets. This assumption defines a rather tight region around stars, which is called the “habitable zone.” The energy absorbed from the host star through its light allows planets in the habitable zones to melt water into liquid. Water would either evaporate or remain ice if the planet is too close to or distant from the star. A recent study suggested that starlight may not be the only energy source that can convert ice into liquid water and maintain it in that state. Dark matter annihilation may produce enough heat in special circumstances for planets that may not be sufficiently heated by their host star. Ordinary matter constitutes only about 20 percent of the matter in the universe, while dark matter makes up about 80 percent of all matter. It is believed that dark matter weakly interacts with atomic nuclei. Therefore, one of the leading models for dark matter is called “weakly interacting massive particles” (WIMPs). In cases where dark matter interacts with nuclei, WIMPs can transfer momentum to the nucleus. Then they can get gravitationally captured and subsequently decay as energetic particles. This process can produce heat as a consequence. On Earth, the concentration of dark matter at its center is not sufficient to produce observable contributions to the planet’s total heat budget. However for planets around stars that are closer to the centers of their galaxy, where the concentration of dark matter is significantly higher, just enough heat may be produced by gravitationally captured and annihilated dark matter. The abundance of planets detected by NASA’s satellite mission-Kepler suggests that perhaps life in the universe might be more abundant than we thought.

3- How Much Digital Information Can Mankind Store?

Original Article: Hilbert, H. & López, P., Science 332, 60 (2011).

Have you ever wondered how much total information is stored by human beings? We store information in two different forms: analog storage such as books, printed photos, and audio cassettes, and digital storage such as hard drives, CDs, DVDs, and the like. A recent paper analyzed how the total information storage and processing ability of human beings changed between the years of 1986 and 2007. The study estimated that the total information stored as of 2007 is 295 exabytes. An exabyte is equal to one million terabytes or one billion gigabytes. If all this information was stored on CDs, this stack of CDs would reach beyond the moon. If it was stored in books, it would be enough to cover the entire United States with 13 layers of books. Interestingly, the information stored by DNA in one single human body is about 300 times larger than the entire amount of information stored by humanity. In 2000, only 25 percent of known information was stored in digital form; this ratio increased to 94 percent in 2007. The area in which the “information revolution” is most evident is computation. The study found that the global computing capacity increased by 58 percent per year during this time. But even at this fast rate of growth, in 2007 the total instructions per second that humankind can carry out on its general-purpose computers were about the same as the maximum number of nerve impulses executed by one human brain per second.

4- Tricking the Brain to Attack Alzheimer’s Disease

Original Articles: Atwal, J. K. et al., Science Translational Medicine 3, 84ra43 (2011) & Yu, Y. J. et al., Science Translational Medicine 3, 84ra44 (2011).

Alzheimer’s disease affects many people, especially in later stages of life, and as the lifespan of humans increases, it becomes much more prevalent everyday. The primary cause of Alzheimer’s disease is unknown, but scientists generally associate the disease with the appearance of plaques and tangles in brain cells, often caused by a protein called amyloid. Hence, a natural strategy would be to attack these proteins that form these plaques. Yet, the biggest obstacle in our brain is the blood-brain barrier, which prevents viruses and other unwanted visitors from entering our most delicate organ. Scientists have tried to overcome this barrier with many different drugs and strategies, but there is no clear winner yet. Two recent studies reported in Science Translational Medicine journal give us a new hope in our fight against Alzheimer’s disease. Scientists devised a clever strategy to trick the gatekeepers of the blood-brain barrier into escorting antibodies against the Alzheimer’s-associated proteins. This method reduced the levels of amyloid by up to 50 percent inside mouse brain cells. Designed antibodies had two arms—one arm to target the enzyme, BACE1, which produces the amyloid, and the other arm to bind to the transferring receptor, which in turn deceived the endothelial cells from the blood-brain barrier to internalize the antibody. There are many other brain disorders that we have a limited arsenal against because of the blood-brain barrier. Hence this new method can be used for these diseases, which opens up a whole new venue of targeting strategies.

Introduction

Human beings have wrestled with questions about the origin of our existence and the fabric of our universe for thousands of years. This questioning formed the discipline of cosmology. Dr. Natarajan explores the nature of our world and shares her perspectives about how new scientific discoveries are reshaping our understanding of the universe and our place in it. Until very recently, the universe had been considered a vast empty space. But the Dark matter theory states that the universe is not empty, but rather filled with an invisible matter. As new mysteries unfold, Dr. Natarajan points out that it is our fundamental human curiosity that leaves us no choice but to explore the universe and how we fit into its grand picture.

M&B: Dr. Natarajan, you work on dark matter in the universe. What is the theory?

It turns out that the bulk of the matter in the universe is not made of ordinary atoms that you and I or the universe that we know and experience is made of, but instead made of this mysterious particle. Ninety percent of all the matter in the universe is dark matter, and we believe this is a set of particles that was created very early in the universe. These particles do not have charge, but they have mass. Since they dominate the mass of the universe, it turns out that they really form the scaffolding in the universe around which all galaxies, stars, and so on, form. They are sort of the basis or the framework within which normal atoms actually cool to form star galaxies, and then have generated us.

M&B: What is the evidence for their existence?

The reason dark matter remains a mystery, – although there is incontrovertible evidence for the existence of dark matter – is the fact that you only detect it indirectly. What I mean by that is you detect its presence because it has mass, and since it doesn’t have any charge it doesn’t couple to any radiation. So you don’t see radiation in any wavelength in the electromagnetic spectrum: no X-rays, no gamma rays, no visible light, nothing. But since dark matter has mass, it aggregates gravitationally, so they feel gravitational pull towards each other and they cluster. It’s the clustering of the dark matter, the fact that it gets compact, that we detect the effects of dark matter.

M&B: What happens near the regions where dark matter clusters? In your research papers you use the bending of the light rays. How do you observe it?

The primary evidence is the gravitational bending of light produced by these aggregates of dark matter. The universe is really composed of a smooth distribution of dark matter, with a lot of clump regions where this dark matter has aggregated, and then enabled the formation of galaxies. The presence of these large amounts of dark matter causes light from background galaxies coming towards us to bend. The actual shapes of galaxies that are behind a big clump of dark matter, which is along our line of sight, are actually distorted when we see it. The dark matter in general is smoothly distributed everywhere in the universe. But there are these particular regions that are denser. So we can look at regions in which the dark matter is not so densely distributed, look at the shapes of undistorted shapes of galaxies, and then use that to infer how much distortion we’re actually seeing when we see a lump, and infer its existence from the distortion. Because the strength of the distortion is directly proportional to the mass, you can directly infer how much mass there is between us and those objects.

M&B: Is there evidence other than the bending of the light rays?

The other evidence eludes to the fact that dark matter actually gives the basis for the formation of stars and galaxies. If you look at the motions of stars and galaxies, you find that, unlike the solar system, if you look at the velocities of the planets in the solar system as a function of distance from the sun you find that it’s falling. So the planets in the inner regions are moving very fast; they feel the gravity of the sun much more strongly than the outer planets, which are not actually moving as fast. So if you plot the velocity from the center or from the sun outwards in the solar system, the velocities are falling. Whereas if you go to a galaxy and you do the same experiment, you look at stars at different radii and you try to see what their speeds look like. They are speeding up as you go outwards. And the only way they can do that is there is something that is sitting outside the galaxy that holds it up as it were, and has gravity. And it turns out that our current picture is that most galaxies have very extended dark matter halos. The key point is that there’s a lot of dark matter sitting outside the galaxy well beyond where we see the stars.

The other compelling lines of evidence for the existence of dark matter come from larger scale observations of the universe. One of the leftovers of the big bang or relic of the big bang is this microwave background radiation that is detected today in the universe. It was a very hot radiation that has cooled with the expansion of the universe, and we are bathed in it. I mean it’s everywhere, in every direction, and measurements of the directional dependence of the microwave background shows that it’s very uniform. But in one part it’s anisotropic, so there are cool zones and hot zones in the sky. On very small scales we see these cold and hot spots. And these and isotropy’s in the microwave background are exactly predicted by this model, the cold dark matter model, which I said you know is postulated on the very early generation of the universe and these dark matter particles.

M&B: So we know that they exist. But what is their essence? What are their properties?

This is still a mysterious kind of beast. In fact, we don’t know the nature, but it appears that it’s collisionless. It’s very counterintuitive. That’s one of the things I find fascinating about the fact that it is so counterintuitive. These particles are actually collisionless. What that means is that when two dark matter particles approach each other, they pass through each other, they don’t actually bounce off of each other, so these particles don’t collide, which means they don’t have pressure, because pressure is generated by collision. So they are pressureless particles that have mass. Gravity holds them together, but they don’t actually collide.

So a current understanding of dark matter is that it’s definitely generated very early in the universe and that it clusters very strongly and it’s distributed on very different scales in the universe, so there’s like a smooth background and there are lots of clumps on top of it and so on.

M&B: As far as the mass of Dark Matter how much mass are we talking about? If there is no clustering, something like in the volume of the earth, for example, how much total dark matter mass do we have?

Well I guess the thing is at the position of the earth and at the position of the sun from the center of our galaxy. We are not really dominated by dark matter anymore, so dark matter at that radius doesn’t constitute significant portion of the mass. We are bathed in it, but the density is quite low. It’s at the innermost part of our galaxy where the density is very, very high, so we actually expect that the inner most regions of our galaxy is a very complicated, violent place where not only do you have a black hole which we know exists. This is a black hole that is not made of dark matter. This is a black hole that has gobbled gas and grown to about a million times the mass of the sun, and which is sitting at the center and it creates a very violent place for stars because it can rip them apart and so on. And this whole system is sort of embedded in this very, very dense region full of dark matter.

M&B: How is your everyday work? Where do you get data about the light rays coming near the regions with high Dark matter density?

A: I’m a theoretical person and what that means is that I actually build models but models that are guided by observations. The theory has transformed in the past 10 to 15 years because of the amount of data that technological progress has given us.

For example, the Hubbell space telescope has really transformed the kind of modeling that can be done. So I actually use data that other people have procured. They’ve cleaned it up and they give it to me. These are very distorted images of background galaxies whose shape has been distorted because of the huge amounts of dark matter that is contained in a cluster of galaxies.

M&B: The bending of the light rays is predicted by the general relativity theory. Is it what you use for your calculations?

A: It’s a beautiful theory. I think that people really have understood the iconic status of Einstein. What is most fascinating about him for me is the profound insights that he had of such despaired phenomenon. There was a way in which he was able to see connections and synthesize. You know the whole understanding that the geometry, the fate and the contents of the universe ought to be linked is a profound insight. And I think you know it’s incredible that he enabled, you know, his mind enabled him to formulate it in the way that he did, which has allowed people like me to use general relativity and the sort of elegance of general relativity because of how simple it is in fact to apply and test.

M&B: This looks like an intriguing line of work?

I want to stress that this is a particularly wonderful time for cosmology. It’s a particularly special time. I don’t want to use the sort of often abused golden age as it were, but it’s the confluence of technological progress with the kind of data that we can obtain and the level of understanding that we have built up. This is a very special time to be doing this kind of work. And while the mystery of what dark matter might be made of, you know, it may or may not get solved in my lifetime.

M&B: If you want to describe your work, what term would you use?

In a more descriptive way, I guess. What I really do is I build a story line. I build a story line for the universe. I mean, I build a story of the sequence of events of how a structure forms and assembles. The key there is that you are guided, you have a few snapshots, so you have a bit of data, but then you have to extrapolate and you make some predictions. The goal of the kind of work that I do is to make predictions, and have them be taken seriously, to either be falsified or shown to be true, and what’s exciting about this particular time is that people can falsify your theories or your models in a very short time.

M&B: Isn’t it interesting that we can actually make a story out of universe?

Well, I mean, I think that what is fascinating, and this is a personal view, what is fascinating about cosmology is the… you know it’s mystical and it’s mysterious at the same time and it’s highly abstract. It’s not intuitive because the scale that I’m working with in terms of distances, masses, and energy are just unfathomable. So there’s a real irresistible pull for certain kinds of people to do this kind of work. And I think the universe is a pretty good subject for a narrative because of the range of phenomena that occur in it. This is possibly why in all ancient civilizations there is some notion of cosmogony and this idea of fascination with where we came from. I don’t want to sound arrogant by saying that it’s the fundamental question, but you know it’s an inescapable question for anybody to ponder where we came from.

M&B: Is there a sense of awe that motivates you in your studies?

There is a sense of wonder that the universe generates and I think that you know personally for me I’m a bit of an adventurist, and I think if I can imagine myself, if I had been born 200, 300 years ago I would have been one of those explorers. And I think there are people like that amongst us always, who want to explore in different ways. I mean, there are some people who want to explore via music. And there are frontiers that they want to break through in music, and they have the creativity to do that. And I think that for a lot of us who are doing science, and cosmology in particular, there is a sense of exploration, there’s a sense of examining or grappling with things that are really at the limits of our capabilities in a way.

M&B: In some ways one of the most important fruits of the process and coming along it’s our imagination. And the human imagination is also a part of the universe.

Absolutely. It is an inescapable part of the universe and what is fascinating is the idea that we have the capability to even contemplate the origin of the universe given that we are a part of the universe.

M&B: Many people approach science in a utilitarian way and this is not what you are doing.

I think that the fact that it is not utilitarian is precisely what attracts me to it. I think it is the other side of the coin of this, which is why we probably aren’t as well funded and we ought to be better funded than we are, because this is such a fundamental human curiosity. There is enormous public interest in what we do and the level of funding that we have does not reflect that. For instance, obviously medicine is very critical. It’s critical to our existence. But the disparity in how they are funded and how the pure sciences are funded is sort of disturbing. Because I think as a culture, as a world, we can afford to indulge in understanding basic sciences partly because there are spinoffs from all the work that we do. It is unpredictable, and I think that is what’s fascinating. There are no guaranteed benefits to human kind and society today that cosmologists can bring. However, they satisfy this hunger for knowing and going beyond, you know, satisfying your hunger and thirst on a day to day basis.

Very few are exempt from such a turbulent point of view; no difference remains between what is collective and what is not, between capitalism, communism and liberalism. The distance in nature-between those who attach their lives to the considerations of eating and drinking, resting, and earning money, having a good time in general, and other beings who are bound to spend their lives in a similar way due to the unchanging character of their nature-becomes smaller day by day. The basic differences between the two sides vanish into thin air one by one, and humanity seeks new directions, despite its own nature.

Religion, piety, morality, free thought, our own perceptions of art are rarely given consideration; power has become so ulcerated as to be unrecognizable, fantasy has taken on the image of lofty ideals and these disagreeable ideas are being forced upon others. Indeed, I have to say that I have a hard time understanding the inner drama of such a terrible fanaticism. Nowadays, when enlightenment has become widespread, when intellectualism is at its apex, the fact that science and ignorance seems to meet at the same spot, contrary to the distance that one would expect to exist between them, suggests a dark complicity and makes the existence of a serious problem obvious. Such a contradiction gives us the impression that the emotional will of some people is miles ahead of their intellectual and logical will.

I believe that in such a dark period, when opposites have become intertwined, when in different sections of society chaos is heaped upon chaos, when shadowy acts of different origins have darkened the face of the Earth, when what is underground reigns over what is above, when polemics and dialectics have become so popular with so many, when hearsay, especially through the use of media, is welcomed as acceptable merchandise, when we have begun to feed upon the lives of others, when the soul of unity has been shaken and different groups are scattered everywhere, when hopes are shattered and wills are paralyzed, when souls give up the fight against desire, there is a burning need to turn toward our own spiritual sphere and listen to our own inner world, to tear ourselves from the dark atmosphere of the bodily realm and sail into the magical atmosphere of a hearty and spiritual life. Those who do not fall into lethargy and return to their usual state as soon as possible will feel the magic and charm of their own inner world; the unfortunate who fail to return and remain in between, or who remain on the other side, continue to resent, hate, slander, lie, and feel contempt, they continue in the dissolution and obstinate disagreement which they have practiced until this day, and even in climates where the sun continues to shine they will dream of dark things, they will mutter dark thoughts, always seeking dark places in which to hide and dark corners in which to live.

One hopes that they would be able to feel the joy of the blessed days and nights that we experience, when showers of light reach everywhere. One hopes they too would abandon the heresy, unbelief, dissension, and sedition in their hearts and that they would be able to respect the chosen understanding and stance of every single soul! Maybe one day these wishes will be fulfilled, but the self-proclaimed enemies of God, the prophets, religion, and piety-once having breathed nothing but materialism, having gone into a frenzy denying divinity, and having plunged into the quicksand of anarchy and nihilism-will never be able to breathe this reviving air. Oh dear Lord, had you only made yourself known to them and released the chains from their hearts!

In every community and society there are people who are inclined to abandon their faith and there have been many times when such people have spun out of control; other communities and societies do not have such powerful places to seek refuge when faced by these abysses and weaknesses as we have. Indeed, they have thoughts which soothe, beliefs which reconcile, days and nights which tremble with joy, festivals and carnivals; but, these days, these nights, these festivals, these carnivals are devoid of any holiness. They are like fireworks, shining for a moment and then are gone, giving only instantaneous pleasure; they are ephemeral and physical, not promising anything in the way of spiritual joy. Indeed, in their worlds you cannot feel the greatness of faith to God, nor can you feel that souls are free from the boundaries of time and space; everything starts with a false and transitory happiness, and takes place in a delirium of flesh. All is then transformed into painful memories, regrettable dreams, and disappointed hopes, and finally everything simply disappears.

In this spiritual atmosphere where we are closely bound to God, every sound, every word, every action is felt like a nursery rhyme and listened to like a melody. These shower down upon us like the rain; we soak up the bounties of these showers. The moon changes its form every night, as if signaling particular times and happy hours, the sun moves to a new spot on the horizon at every dawn, awakening our feelings and thoughts in a new period of time, causing our dreams to follow it, presenting memories to us that resemble the river Kawthar, promised to us in Heaven. The past becomes like a veil of many colors draped before our eyes, the happy future is the apex of our dreams, waiting for us with open arms and we, who have been freed from the narrow confines of time, live the multiplicity of yesterday-today-tomorrow simultaneously and, like the angels, feel all the joys of surpassing time. It is impossible for those who are not fed from the same source, those who do not share the same feelings and thoughts, to feel and understand the holy depths or the happiness and joy like the rivers of Paradise to the same extent.

Our faith, our horizons of thought, and our manner-characteristics of the fortunate, but at the same time belonging to a little-wronged nation of the world-have become, through being formed and re-formed in the mold of the collective personality, greatly refined and adorned with universal values. The truth is that in these characteristics the holy sadness of our hearts and the enthusiasm of our souls, like water running between the rocks, are felt and heard. Indeed, those who listen to what we have to say always hear the melodies of the pain of separation voiced along with hope; they hear the notes of reunion, of the sweet and eternal search for home in our intonation and manner. Indeed, while on the one hand we murmur “Oh, cup bearer, I have burnt in the flames of love, give me a cup of water,” on the other we say “I have dipped my finger in and tasted the honey of love, give me a cup of water,” and thus we are able to turn our grief into smiles. Our tongues speak sometimes of love and sometimes of weariness; though love and weariness cause pain to others, in them we always hear, like Rumi, the poem of longing for the realm that we have left to come here. Love and weariness to us are like a plea from the tongue of the soul, stemming from a sorrowful desire for eternity. Since our beliefs and feelings take us to the magical worlds of beyond, we almost always feel sadness and joy intertwined; we hear the sounds of crying and laughing as different notes of the same melody. We respond to the troubled heaving of our breasts with smiles on our faces, as our eyes overflow with tears, our conscience takes upon a red hue with the roses of the Iram gardens.

Even though it may not be easy for every individual, our connection to God is the most natural attitude that we can adopt; our relation with Him is like a spell that transforms all the moments of our life into enthusiasm and joy. Our hearts that beat with feelings toward Him fill and re-fill with the dream of this gaze; we are able to live through the bitterest autumns in our hearts because we have the joy of spring. Our souls adopt the most enviable attitudes with instincts of particular feelings and joy that are the result of our connection with the All-Glorious One; thus transformed, they make us feel a refreshed enthusiasm, a new opening and revelation, even at moments when we are filled with sadness and grief. Pleasure or sadness, revelation or sorrow, all these emotions undergo metamorphoses in our hearts, as they beat with faith and speak to us of the most natural pleasures and the most realistic expectations. It is a fact that we, too, experience interconnected moments of ease and hardship, sweet weeks and bitter days, light and darkness which come and pass, like day and night. However, we sip the unsurpassable benevolence and joys from the hands of all these tribulations, because we have our beliefs, our connection to the Just One and our hopes! Those who do not recognize the trials and pleasures to be the product of the same will writhe in never-ending agony, while in our own atmosphere we see clearly that everything will be transformed into deep compassion. We taste a whole life, with its bitter and sweet facets like Kawthar, the blessed water of Paradise, in everything that we eat and drink, at every place that we inhabit, with all the beautifully divine discoveries of our own inner world. With all of their different wavelengths, we feel our sorrows shrink in the face of happiness, feel our pain melt away in pleasure and feel how our lives flow into glazed cisterns in a spectrum of colors. Our mortality is transformed into eternity; we exude smiles even when we cry.

In our world, the beliefs and the expectations that emerge from the heart of those beliefs are so intertwined with our lives that each chapter of our lives lends us the wings of the station of prayer and takes us to the gate of the Hereafter. It takes us there and lets our hearts drink of the beauties of heaven. In this way, we feel as if we are inhaling the scents of heaven. Even if we should let ourselves be swept along by our daily lives, the calls for prayer, songs that exalt God, the various sounds of prayer, the recitation of the names of God, those who give Him thanks, calling out His Uniqueness, letting this spill from the windows of the mosques, all draw us to their climate; they paint our souls with their hues, they give a tambour-like voice to our hearts, they make them sigh like a flute and excite them with the happiness of music. These sounds excite our souls and we are charmed by the mysteries pertaining to God, the charm of these mysteries which comes galloping from the depths of our inner world and which spreads to all our senses, this charm which tints the gardens of heaven in our thoughts and which flows past our lips like cascades of inspiration. Thus charmed, we stand awe-struck.

This charm, this recognition of the mysteries pertaining to God, reaches a higher level on the blessed days and nights when limitless abundance and bounty are showered upon us. This is true to such an extent that everything around us ascends in a state of joy, every corner takes on a spiritual hue and the excitement of our souls, aiming at metaphysical destinations, reaches its apex, or in Sufi terms, our souls reach the highest heaven of maturity. To the degree that we can hear and listen to what is all around us, we too rejoice like children who feel as if they are in the fair grounds of joy; thus we experience the happiness and joy of a feast day.

In such a world, the dawn flows into our houses from the doors and windows like an awaited guest; the evening comes into our private chambers like a lover; the night clings to us with its associations of reunion with the Confidant; and in every valley hands are raised up toward Him in prayer, ready to receive the gifts that will come from Him, assuming a state of metaphysical tension with the power of the soul, sighing, saying “Hold my hand dear Confidant, hold it, for I cannot do without You.”

In such a world, prayers roar like the booming voices of Gulbang hymns and echo like the voice and breath of the divine depths; the warm solitude of the night envelopes our souls like silk; our pulses beat with the excitement of one who has received good tidings. Perhaps some of us keep singing His praises, come rain or shine, like the nightingale that breaks its heart in an effort to express the ideal rhythm for its emotions with the most touching of sounds. In a word, everyone is humming a melody with never-ending agony and joy, never-fading love and excitement, listening to the shivering of their souls and letting others hear it, too. Everyone sighs with the fever of love and makes other people feel it. Yes, as they reflect on the excitement in their souls and the inspiration of their hearts, expressing themselves one last time, they become the mouthpiece for the feelings shared by all and they are able to speak of the hidden meanings that they want to speak of but fail to verbalize.

The horizon of living yesterday-today-tomorrow at the same time with such a degree of faith and hope, of love and recognition of the mysteries that pertain to God, gives such a depth to life that each heart in the orbit of the hereafter finds itself wrapped up in the melodious harmony of emotions and ideas and is freed from the limiting, stifling effects of matter. I believe that the strongest basis of all human relations, the purest source of all pleasures, and the fountain of all love, longing, attraction, and gravity is this faith and hope. Every disciple of the heart who attains this faith and hope can experience and feel the state of being outside of time, with the ability to sense all of its depths.

Indeed, to the extent that one can attain this view, one can feel existence in a different manner, evaluate things in a different way and melt in on oneself with the color, taste, aroma and accent of manifestations from the Eternal; these attributes pervade everything, and people can reach a second existence with a new “birth after death.” During such joyful hours, when the internal gaze is focused on that which is behind the visual scene of existence, one feels all the joys of being. One feels as if one has taken a shower in wisdom, as if one is freed from the weight of all things that are alien to one. The distant heavens shower blessings down upon these hearts, hearts thirsty for love and galloping with longing and affection; all hearts that live in fear of drying up are quenched. Celestial flowers flourish in these showers adorned with dreams!

Some of us may not be able to comprehend this state-a state which becomes a succession of struggle (to overcome the darkness with its all connotation) and dawn-of these people of faith and horizon; but all these are phenomena of the heart, soul and emotions. Living through the countless revelations of life, no one but the active heroes of the dawn and of the great strife can understand this love, enthusiasm, poetry, and music poured into our souls by the Eternal One. Those who do not understand this will not be able to understand these heroes, either. Those who remain distant to this fine and delicate life live in the darkness, while the comprehension of those who have found a position from where they can view the truth in such a way that it appears as obvious as it really is always feel this gift in all its wavelengths, sip it like the rivers of Paradise and live their earthly lives as if in Heaven.

Who knows how many more times we will speak of this never-ending pleasure and joy, in the delight of a festival, of a feast day! How ever many more times we may speak of it-the faults of the speaker’s mode of expression aside-we will still listen with pleasure and try to share it with others.

In this work we study a verse from the Qur’an, the 47th verse of the Sura al-Dhariyat (The Winds that Scatter), under the light of new discoveries in the field of astrophysics. We note that recent evidence about the accelerating expansion of the universe is also strongly consistent with this verse, although this has shocked the scientific community. In the last part of the article, we discuss possible relations of “metaphysical dimensions” and the concept of “the seven layers” with the word “sama” (translated in to English as “heaven”) as mentioned in the verse.

The existence of the universe is perhaps one of the greatest mysteries in science and philosophy. No convincing argument has been ever put forward that has enabled us to understand this amazing event, not since the beginning of modern science. Religions like Islam, Christianity, and Judaism, on the other hand, explain that the Creator built our robust universe directly out of physical nothingness, independent of any cause. Therefore, the initial creation of such universe would be impossible to explain physically (M. F. Gulen, from his conference on “Evolution and reality”).

In his translation of the relevant verse, S. Yildirim has noted that God keeps the universe expanding and He will continue to do so. Yildirim attributes two meanings to the word musiun in the verse; the first is the owner of great power, strength and wealth; the second is one who expands. Thus, it should not be a surprise to learn that this verse is indeed describing a continually-expanding universe. This might further lead Muslims to think that the Creator has not left the universe unattended after the Big Bang, but rather it is He who has kept creating and expanding it.

In the 1920’s a discovery was made that completely changed our perception of space. It was discovered that distant stars depart from the solar system and leave us even more and more alone in dark space. Then, Fr. Georges-Henri Lemaître, a Belgian astrophysicist, mathematician, and Catholic priest, proposed the idea of the expanding universe. Despite its finite size, it was believed that the universe was expanding.

We can explain this fact simply by an analogy. Think of a toy balloon with spots on it. Mark one of those spots and inflate the balloon. As we inflate it, we observe that all other spots on the surface of the balloon move away from the marked one. So, if we replace the balloon with our universe, the spots will be the stars and planets. If the universe is expanding indeed, then we expect them to be moving away from each other. In other words, the distances between heavenly bodies must be increasing.

Unfortunately, we don’t have a gigantic ruler to measure such immense distances. However, there are other means, such as measuring wave frequencies. Consider the following analogy: Someone throws one ball every second toward a target. Assume that balls travel with constant velocity. If the thrower is stationary, the target will receive one ball every second. However, if the thrower is moving towards the target, it will receive balls more frequently because the balls will be less spaced out. The converse is true if the thrower is moving away from the target. So it is actually the wavelength which is affected; as a consequence, the perceived frequency is also affected. That is, the distances between the waves emitted by objects moving away from us (wavelength) must be increasing, so the frequency decreasing. Likewise, think of an ambulance siren coming towards you and going away from you. It is a good example showing that while an acoustic source that is approaching us emits a higher frequency, the same source radiates lower frequency when going away from us. In physics this is known as the Doppler effect.

Red shift

This phenomenon does not only occur with sound waves, but also with electromagnetic waves. When we think of the spectrum of light, violet at one end has the shortest wavelength and red at the other end has the longest wavelength of visible light. So, any wave of light shifting toward red means the source is moving away from us. It has been determined that the frequency of light emitted by the elements within distant stars shift to a lower frequency, which is called a red shift.

It is this shift that makes astrophysicists think that the universe is expanding. One mustn’t be confused by red shift. This terminology is just used to explain in what direction the frequency is actually shifting on the spectrum. Those signals captured from distant stars have a much smaller frequency (much higher wavelength) than that of red light and they are indeed in the microwave regime and shifting to even much smaller frequency radio waves.

In 2002, an article presenting new evidence of the accelerating expansion of the universe was published by the Royal Astronomical Society. It was not so long ago, only five years, that general opinion concurred with a decelerating expansion. However, the first evidence found by two astronomers in that year led us into a universe that expands in an accelerating fashion, contrary to previous views. This result was absolutely unexpected, because many scientists believed that expansion would slow down due to gravity. Another interesting fact is that if space were to cease expanding, this would be in contradiction to the above verse. God, however, by never allowing this to happen, shows how futile the actions of those who deny His verses are and how extensive His power is, as well as how purposefully He creates.

Dark energy

The groups who worked in the above study figured out, from the brightness of supernovas in distant galaxies, that the universe must expand more and more in the future due to a peculiar dark energy within it. The concept of dark energy was first postulated by Einstein, who named it the “cosmological constant.” However, since this did not fit in well with his theory of general relativity, he withdrew it and said that it was a scientific blunder. Since then, dark energy has had a rather controversial history.

A team of 27 astronomers, directed by Professor Efstathiou of Cambridge University, proposed strong evidence supporting the existence of dark matter, based on completely novel techniques. Their results, which were consistent with previous supernovas, showed that the universe is indeed full of dark matter. Professor Efstathiou thinks that the explanation of dark energy might include additional dimensions like creation (Big Bang) as well. Fr. Lemaître also proposed the expanding universe theory at an opportune time since Edwin Hubble would soon release his red shift observations that strongly supported an expanding universe and, consequently, the Big Bang theory. Here, the Big Bang is seen as the beginning of a continuous expansion.

The verse seems to tell us miraculously that the expansion of the universe will not cease, despite our limited knowledge of the physical reason for its acceleration.

The Hubble Telescope

Another article, published in Nature, presents us the first and deepest picture of space taken by the Hubble Space Telescope. This caused the astronomers to compete in solving the mysteries of the arts of God. The picture, also known as the Hubble Ultra Deep Field, was broadcasted and published in various programs and journals. It has not only shown us the farthest stars of the universe, but the youngest as well. It was very difficult to detect such weak light with the former technology. This picture reveals the embryonic universe, with an age of only 500 million years old. Estimated age of the universe is 13-14 billion years. Three physicists from American Natural History Museum in New York started a competition to publish an article on the Ultra Deep Field picture after the data was disclosed. They hope to answer many questions about the past and future universe. A group at the Stony Brook University, New York, directed by Kenneth Lanzetta, analysed the embryonic samples in the picture to try to discover when various galaxies had been born and how they had evolved. Two other groups are studying the motions of stars and galaxies, as the picture is a result of data collected over a month.

Having looked at the expansion of universe under the light of recent discoveries, now we turn our attention to two other arguments that could be relevant to expansion. Namely, ether (a substance which it is believed fills up the vast universe and which is the ultimate building block of the space), and the seven-layer-universe.

Despite the Michelson-Morley experiment, which argued against theory of luminiferous ether, the propagation of electric, light, or heat in space shows the existence of a substance through which they flow. The Michelson-Morley experiment is nothing more than just a test of the non-existence of certain qualities of ether. For example, in order to show the existence of photons, of which light is made up, we cannot go beyond showing the features of photons. In other words, depending on how we have defined its qualities, we can observe different aspects in the photon, ether, or anything else. In fact, even today, we don’t really know what a photon really is, although we observe its affects every day. In short, it is not possible to show the non-existence of phenomena that cannot be absolutely defined. Instead, we can only test the existence of the properties that we have defined and attributed to them, and thus we better understand their nature of existence in the context of those pre-defined qualities. Hence, the existence of ether is still controversial and needs more thorough research.

Seven layers

Regarding the seven-layer-universe, on the other hand, how is it possible for ether to manifest itself in seven heavens? It may be that these seven layers are not all posed above our heads, but rather that they may be found one with another. The universe is composed of many systems and networks that are the building blocks of their counterparts on larger scales. Each system is governed by laws, which differ slightly from one another. Inside the atom there exists a proton with its unique organization and in a proton we find quarks. For example, communication between protons and electrons is mediated by the electromagnetic force, while the quarks inside the protons communicate via the strong force. These interleaved circles show us that the universe is indeed composed of numerous layers.

We may use these layers for the metaphysical world as well. The human being is not only composed of matter, but also has a mind, a soul, and intelligence. Although these components are accepted as existing by all, their exact nature has not yet been explained by positive sciences.

It seems that the universe is composed of at least two different worlds: The material world (physical) and the immaterial (metaphysical) world. Are these two worlds completely separate, or do they have some features in common? In fact, the existence of humanity might prove to be this common set. But, it may also be true for the universe itself. Nursi states that the distant galaxies, stars and planets are not empty, but home to many spirits and angels who have their own consciences. Thus, one can say that despite the boundaries which separate these two worlds, such as different numbers of temporal and spatial dimensions, they constitute a whole, the Universe. The interaction between them will never fail as long as the universe exists.

The existence of two separate worlds is not that difficult to believe, but there is more:

It is He Who (prepared the earth for your life before He gave you life, and) created all that is in the world for you (in order to create you – the human species – and make the earth suitable for your life); then He directed (His Knowledge, Will, Power, and Favor) to the heaven, and formed it into seven heavens. He has full knowledge of everything. (Baqara 2:29)

The Qur’an calls the heaven where the sun, moon and stars are the lowest heaven or the heaven of the world (Mulk 67:5). The other six heavens may be the heavens of the worlds of the Hereafter.1 We are not sure whether this seven-layer heavens can only be attributed to the physical universe. It might be able to apply to the universe as a whole, with its all seen and unseen layers as well. Even the worlds of angels and spirits may be expanding in accordance with the laws therein, to show how the power and the wealth of God are comprehended in those worlds as well. Although our Earth is finite, the expansion may not be restricted to our finite world, but it may continue in infinite worlds as well.

It is possible that the space being filled with ether has an important role in paving the orbits of planets or stars, as well as other heavenly bodies. We believe that future studies on dark matter, ether, and string theory will help us to better understand the expansion process of the universe.

“We were thrilled to see a dome we came across in the cave after turning a few curves as we drifted along the current of the sea. What we saw in this pitch dark corner of the cave was a glorious sky adorned with thousands of stars and we felt as if on a remote planet yet unidentified. These mysterious stars would suddenly fade out as if they were frightened by each noise we made, the splash of the oars, or waves hitting the boat. They would glow back marvelously after a short while when their fear was over. It was an amazing luminousness coming out of thousands of lights.”

A scientist with infinite determination, Professor Illies says they now know who the players were who were involved in and the realities behind this enchanting show: Arachnocampa luminosa. This self-glowing fly, which is endowed with a peculiar light-radiating system, is known by different names in other parts of the world.

Mysterious light-radiating mechanisms

A microscopic organ found in the stomach of the glowworm is the source of light which creates the glow. Two chemicals are produced in two very close locations in this organ which is essential for the glowworm to continue its existence: Luciferin and Luciferase. These glowworms have no idea that they glow when these chemicals are mixed together with oxygen as the third component, which is taken in via respiration. They are neither blessed with the intellectual capacity to determine how much of these chemicals should be utilized or which stages this chemical reaction will go through; they are unaware of the nature of this glow, but they can radiate it for three consecutive hours thanks to this complex mechanism installed within.

A normal electric bulb can transform a maximum of 3-4% of the electrical energy supplied into light, whereas this output is 10% in the fluorescent bulb; the rest of the energy is released as heat, a waste in production. The ideal 100% efficiency would be to transform all energy into light with no release as heat. Today’s technology has not yet reached that level of illumination; even the most productive devices release heat to some degree. For thousands of years, however, the tiny bodies of glowworms are like power stations, yielding 100% light, a capacity which engineers have not yet achieved.

Can Darwinism explain a luminosa’s glowing mechanism?

The glowworms of the Waitomo caves are equipped with bioluminescence, a system of illumination that is the result of chemical reactions. Researchers are seeking answers to why Arachnocampa luminosa lives in the cave and radiates light. The first answer that comes to mind is that it uses this light to catch its prey. In a dark cave, the strong light attracts the prey which is caught by the sticky droplets secreted along silk threads that hang from a web. The glowworm digests its prey together with this thread. The explanations of evolutionists, based on natural causes regarding this complex bioengineering mechanism possessed by a worm, are far from satisfactory.

These explanations were confirmed (!) by behaviorist Niko Tinbergen, a Nobel-prize winner in medicine, in the introduction to his The Animal in its World (1972): “It is manifest that an animal can do stunning things and it can get accustomed to its habitat. The environment has shaped the evolution’s path, and it still does.” A hundred years after Darwin, Konrad Lorenz would state the following with additional emphasis: “The conviction that all the important details found in the structures and behavior of living things can be explained by the mechanisms discovered by Charles Darwin becomes stronger as I am getting older.” A superficial and distorted perspective on nature…

If we were to explain animal behavior according to the perception of evolutionists we would have to accept that during the evolution process of Arachnocampa the luciferin chemical came into being at a stage that was followed by the formation of lusiferase enzyme coincidentally, and thus the glowing started. Recently, it has been discovered that the larvae of glowworms also produce light. A larvae feeds on microorganisms (fungi spores) which are completely insensitive to light; this proves that the light produced is not a necessity for nutrition. Natural selection, a mechanism proposed by Darwin, cannot explain why the larvae wastes the energy obtained via nutrition under difficult circumstances by glowing. Each adult Arachnocampa goes through the larvae stage, which spoils Darwin’s “chain of development.” Coincidental mutations, natural selection, and re-combinations present nothing but contradictions.

According to an evolutionist scenario the latter stages of development witnessed one of the Arachnocampas started to produce light for no obvious reason (!). It became stronger with this new physiologic aspect; although it drew attention with this new light it did not become a prey to its enemies, but on the contrary it snared other insects more easily. It left this new hunting skill as a legacy for future generations (!). In the meantime, the remaining old-type Arachnocampas, which did not have this skill, became extinct with no trace left on earth. The glowworm thus perfected its physiology and anatomy, and there was no need for change for millions of years to come!

Evolutionists can do nothing but explain with unintelligent mechanisms the glowing that is created by a reflecting tissue at the back of the body and the fact that the light is condensed to be directed towards one course. Otherwise the light would only illuminate the roof of the cave. They further explain, with an analysis that is not based on logic, that the glowworm can detect air waves (like bats hunting by ultrasound waves), and thus can turn on and off the light, control the glow and hide from danger. It is so difficult for an evolutionist to accept creation that they adhere blindly to these theories. If one would argue how baseless these explanations were, they are likely to receive the response “a scientist should not be narrow-minded” and that “we are not at that stage to appreciate the importance of coincidence in the formation of such behaviors.” “This will change in the future when we attain the necessary information.”

Professor Ernst Mayr assures (!) us about the role of coincidence: “The variety in nature produced by mutation and re-combination takes place only by coincidence. The destiny of every being is determined by surrounding factors through selection. There are no long term decisions in nature. The existence of a thing is determined by these mechanisms for that moment.” Mayr would probably find it a silly question to ask whether the windshield wipers of his car came into being by coincidence.

“Surrounding factors determining perfection” brings along several questions. The limestone which forms the essential material of a cave is biologically dead, and it does not sound very logical to depict it as the primary factor in the occurrence of such a complex organism. There are a number of insects that live in these caves but which do not possess the characteristics of Aluminosa. Moreover, from a neo-Darwinist approach, insects living in these dark caves should have lost their vision in accordance with the theory. The natural selection mechanism argues that eyes which are of no use in these dark caves should be an unnecessary organ. These organisms could have channeled the energy they allocated for their eyes for a more functional sense, and this could avail them many advantages. On the contrary, these glowworms have perfect eyesight which they use in communication.

Science develops theories for observable objects. Under the twilight of the lack of information and blurred perspective on nature, these theories are perceived as realities. And science becomes the slave of the genie that science has released from the lamp. Joachim Illies underlines this as follows: “It is better not to disturb the sacred cows for no reason. Darwinism has become one of those sacred cows. These cows stand in the middle of the road and the traffic flows into byways so as not to disturb them.”

In the world of living things, examples of Arachnocampa luminosa are not few and they cause metaphysical headaches for the Darwinists. In the face of such pain they load the burden of keeping silent on the “Darwinist coincidence.” They silence their conscience and distort reality; their explanations do not make any sense. We wish they could turn to God Almighty for once, rather than chasing after coincidence and natural selection up so many blind alleys.

The various eras

The prehistoric era is considered an unknowable time inhabited by primitive and brutal humans. This era ends with the beginning of Antiquity, which saw the rise of ancient civilizations in Egypt, Mesopotamia, India, and China. However, the West downplays them, as if they somehow damage its ego and pride.

Then comes late Antiquity, the era of classical Greece and Rome, a sort of golden age during which the West was enlightened by such philosophers as Socrates, Aristotle, and Plato, as well as by beautiful artistic and literary creations. However, these people worshipped deities, did not obey any moral codes, and also had a great thirst for stories about bandits. The Greeks of this time, however, failed to comprehend the reality of the miraculous incidents in nature and so worshipped the sun, wind, fire, and forests. Rome, a civilization based upon law, categorized people into social classes varying from superior to slave. In 380, it adopted Christianity as its official religion. Antiquity ended after the empire’s division into two and the collapse of its western portion not too long after the division.

The next approximately 1,000 years are known as the medieval era. It started off by destroying Antiquity’s intellectual and artistic works and forbidding independent thought. The Christian church, after closing down Athens Plato Academy in 529, turned toward monasticism and rejected Greek philosophy. Monasteries soon gained a monopoly over education, thought, and meditation. This is why the times became dark, for the clergy monopolized science, culture, art, literature, and thought. Religion, which provides people with peace, happiness, and security, was distorted and, assuming a personalized form, became a means of torment, oppression, and harassment through the above-mentioned bans, church taxes, and the Inquisition.

During this era, which considered such moral values such as equality, justice, love, and respect outdated, people were classified as clergy, which produced nothing but confiscated and controlled everything; nobles, who owned and exploited the land and treated the peasants as serfs; peasants who worked but could only silence their hunger; and slaves. The medieval era ended with the advent of the Renaissance (rebirth or revival), which began in northern Italy in the late fourteenth century and spread north thereafter. Antiquity’s thought, art, and culture were revived, and people tried to free themselves from feudalism and church authority.

What really happened during the dark ages?

The Dark Ages are often ignored. However, this was the time when Europe rediscovered Antiquity’s accomplishments and thought due to its contacts with Muslim Spain and Byzantium. Given this reality, why does the typical timeline skip over this period, especially since it was far from dark outside of Europe? One case stands out: the Arabian peninsula, where a new religious movement (Islam) and the beginnings of its civilization had appeared by 610. In stark contrast with Europe, it proclaimed that people were obligated to seek knowledge, fight ignorance, and improve their condition in life.

Islam’s Prophet, Muhammad, accepted Judaism and Christianity as true and set about re-establishing belief in God’s Oneness. He preached the freedom of conscience and religion by declaring there is no force in religion and that people should embrace Islam only if they sincerely believed in its truth. The Qur’an rejected all humanized angels and rejected Original Sin by stating that people would be rewarded or punished only for their own deeds in the afterlife.

The security of life, goods, and honor were accepted as basic human rights, and thus guaranteed protection. All people, without exception, had specific property rights. Each person’s rights were guaranteed by being considered halal (lawful) or haram (unlawful), with various gradations in between. Social solidarity was ensured by zakat (obligatory charity) and sadaqah (voluntary charity). This also prevented the formation of social classes and any possible class hostility. Addressing humanity as O people to show their equality, the Qur’an rejected medieval Europe’s social stratification by proclaiming that superiority depended upon belief, God-consciousness, good conduct, and helping others.

In the pre-Islamic period, women were viewed as property and daughters were considered a source of shame for their fathers. Islam made them revered spouses and beloved daughters, superior to men in being mothers, and equal in obtaining property and justice. Islam sought to abolish slavery, a universal norm at the time, gradually by introducing various sanctions. First of all, it recognized slaves as full human beings who had to be treated according to the dictum Let them eat what you eat, and let them wear what you wear. Moreover, God ordered the freeing of slaves to atone for some sins.

Islam emphasized the wrongness of medieval Europe’s social stratification by stating that everybody was equal before law. The principle of freedom from obligation, which states that everybody is essentially innocent until proven guilty, was also established. All of these practices, which have existed from the first day of Islam, have not been cancelled just because many Muslims have not observed them.

Conclusion

While Europe remained in the dark on all of the above issues, the sun of Islam was beginning to illuminate many other areas of the world. Thus, humanity’s progress toward real civilization was led by Islam during an era that was supposedly dark. As Islamic history shows, that classification betrays some obvious personal or civilizational bias.

Europe’s Dark Age was a time of great intellectual ferment in the Islamic world. Many philosophical, mathematical, medical, astronomical, and medical works produced by classical Greece and Rome, as well as India and other civilizations, was translated into Arabic by Muslims, Jews, and Christians. Among them were the works of Aristotle, Plato, Socrates, Hippocrates, Euclid, Galinos, Ptolemy, and Archimedes. Such translations had a major impact upon Europe when they finally reached its shores, for they were instrumental in starting the Renaissance.

The present division of history into certain eras is based upon a Western view of history and what is important. The church rejected Antiquity’s accomplishments and caused it to be forgotten in Europe for many centuries. However, religion cannot be condemned for this, for the people who did such things deviated from its teachings. While Europe was lost in darkness, Muslims were busy creating an Islamic civilization that first enlightened their own lands and then spread outwards Spain (Andalusia). Muslim Spain eventually became a bridge between the Islamic world and Christian Europe.

Greek civilization established the beautiful, Romans established the law, and the Semites contributed religion. The Chinese actualized the useful, India gave humanity its imagination and mysticism, and Europe gave science. Islamic civilization assumed its rightful place among the world’s civilizations by exhibiting an intrinsic and original style in areas such as thought, science, art, culture, and literature. Such a magnificent civilization, if it is to be divided into eras, should be divided according to its own history, and not by the West’s criteria. Just as the West arose again, thanks to Islamic civilization, so will the Islamic world rise again, God willing.

Cosmology is the study of the universe’s beginning, formation, and evolution. Humanity has devised many cosmological theories. For example, ancient Greeks thought the universe was composed of four elements: earth, wind, fire, and water. Now, despite several millennia of effort, modern cosmologists are even worse off.

About 60 years ago, Fritz Zwicky realized that clusters of galaxies consist mainly of matter in some non-luminous form, defined as matter that we cannot see with our telescopes. Now, after decades of accumulated observations, most astronomers believe that as much as 90 percent of this material may consist of objects or particles that cannot be seen. That is, most of the matter in the universe does not radiate light. Previously, people called this phenomenon missing matter. Contemporary researchers prefer dark matter, for it is the light, not the matter, that is missing.

In this article, I discuss evidence that proves the existence of dark matter, possible candidates for dark matter, and the importance of dark matter in understanding the universe’s beginning and end according to the Big Bang theory.

Obsering the invisible

As dark matter emits no electromagnetic radiation (e.g., light, radio waves, and X-rays), it cannot be seen by a telescope. However, we can infer its existence through its gravitational effects on luminous matter. The most obvious example of this is observed when looking at the rotation rates of galaxies. Using the resulting information, scientists can calculate the speeds of stars as they rotate around a galaxy’s center (orbital speeds) in two different ways. The first way is to look at the light coming from stars in different parts of a galaxy. Through a close study of that light’s properties, they can deduce how fast and in what direction (whether toward or away from us) that star is rotating. The second way is based upon gravitational physics. Given that we know how much matter the galaxy contains, we can calculate how fast stars must be orbiting around its center. By accounting for all of the galaxy’s luminous matter (e.g., stars, gas, and dust), astronomers can calculate the star’s orbital speeds.

But there is a problem here: The two results do not agree. The only way to account for this difference is to posit the existence of a large quantity of dark matter in the galaxies. To explain the astronomical observations, this dark matter must surround the galaxy in a large spherical distribution (known as a galactic halo).

Is the gravity of the galaxies seen in this image strong enough to contain the glowing hot gas? Superposed on an optical picture of a group of galaxies is an image taken in X-ray light. The X-ray picture shows confined hot gas highlighted in false red color and provides clear evidence that the gravity exerted in groups and clusters of galaxies exceeds all of the individual component galaxies combined. The extra gravity is attributed to dark matter, the nature and abundance of which is one of the biggest mysteries in astrophysics today. Credit: Richard Mushotzky (*)

Another effect, known as gravitational lensing, gives evidence for dark matter’s existence. This effect occurs when a massive object’s gravity bends the light that is passing by. For instance, when a cluster of galaxies blocks our view of another galaxy behind it, the cluster’s gravity warps the more distant galaxy’s light into rings or arcs, depending on the geometry involved. By observing these rings, one can calculate how much mass should be present inside the galaxy to produce this pattern. Such calculations confirm that clusters contain far more mass than the luminous matter suggests.

Image of the rich galaxy cluster Abell 2218, taken with the Hubble Space Telescope. This cluster shows evidence of multiple lensing images, as well as numerous strong and weak arcs. Using information about the arcs and multiple images allows astronomers to reconstruct the mass distribution, which then gives us knowledge about the distribution of dark matter. (*)

Dark matter defined

Understanding dark matter is a key to other important issues in cosmology, such as how much mass the universe contains, how galaxies formed, and whether or not the universe will expand forever.

The posited explanations for dark matter can be grouped into three main categories:

– Dark matter could be some kind of ordinary matter that emits or reflects too little radiation for our instruments to detect. Such objects are known as massive astrophysical compact halo objects (MACHOs) and may be ultrafaint stars, large or small black holes, cold gas, or dust scattered around the universe.

– Dark matter could consist of exotic, unfamiliar particles (i.e., different from such known particles as electrons, protons, and neutrons) that we have not figured out how to observe. These are known as weakly interacting massive particles (WIMPS). Despite the many theories about them, their existence remains unconfirmed. These exotic particles are thought to have very small masses (smaller than atoms), meaning that there would have to be a huge number of them to make up the missing matter. Thus, millions of WIMPs are passing through Earth and us. They interact with ordinary matter only by means of gravity. Since the interaction is very weak, it is difficult to detect them.

Our understanding of gravity needs a major revision–but most physicists do not consider this option seriously.

Dark matter and the universe

The search for dark matter is more than trying to explain discrepancies in galactic mass calculations, for it is closely related to how the universe was formed and will end.

The Big Bang theory, which tries to explain how the universe was formed, maintains that in the beginning, everything was compressed into a single point. Then, a great explosion resulted in the universe being formed. It is still expanding. This theory is based on the fact that all galaxies, when observed with telescopes, are moving away from each other. After this explosion, matter started clumping together to form the stars and galaxies we see today.

The picture shows mankind’s deepest, most detailed visible view of the universe provided by Hubble telescope. Representing a narrow keyhole view stretching to the visible horizon of the universe, the Hubble Deep Field image covers a speck of the sky only about the width of a dime 75 feet away. Though the field is a very small sample of the, it is considered representative of the typical distribution of galaxies in space, because the universe, statistically, looks largely the same in all directions. In this picture, Hubble uncovered a bewildering assortment of at least 1,500 galaxies at various stages of evolution. (*)

One problem with this theory is explaining how the stars and galaxies were formed. If matter initially was distributed evenly in all directions, what caused it to clump together in some regions and form stars and galaxies? Gravity alone cannot cause this in a smooth universe, and so something had to supply the initial gravity that allowed galaxies to form. Physicists suggest that dark matter WIMPs accomplished this task. Since WIMPs only affect ordinary matter gravitationally, physicists say this dark matter could be the seed of galactic formation.

According to the Big Bang theory, there are three possibilities for the universe’s future. In a closed universe, gravity is strong enough to stop the expansion eventually and pull everything back to a single point. In an open universe, gravity cannot stop the expansion and so it will continue forever. In a flat universe, there is just the right amount of mass so that gravity can stop the expansion but not pull it back into one point.

The amount of dark matter that exists is crucial to determining the universe’s fate, because the Big Bang theory posits that the amount of mass in the universe determines gravity’s strength and, by extension, whether the universe will be closed, open, or flat. To quantify this, scientists define a constant, called Omega, as the ratio of the universe’s density to some critical density. A flat universe is said to have an Omega of 1, meaning that its density is equal to that of the critical density. If the density is greater than 1, the universe is closed; if it is less than 1, is be open. Without dark matter, the universe’s observed density is between 0.01 and 0.1. Therefore we live in an open universe. If a lot of dark matter were present, the universe would be closed. If there were just the right amount present, it would be flat.

Conclusion

The discovery of dark matter could affect our view of our place in the universe. If its existence were proven, our world and its inhabitants would be made of something comprising an insignificant portion of the physical universe. This probably would not affect our daily life, but would create a new scientific paradigm. In this sense, the discovery of dark matter would be as revolutionary as finding of extraterrestrial life.
