Think of yourself as a desert ant. You leave your nest to search for food early in the morning in the deserts of Tunisia, except you do not know where to find food. You, therefore, walk randomly in the desert in a circuitous outward path from your nest until you find food. If you would find food, how do you get it back to your home? How do you go back without having left for yourself any traces or signs in the wasteland, without knowing where you located, and most importantly, without ending up stranded in the scorching heat of the desert? Could you accomplish coming back each day with food? Well, desert ants can.

To find out how ants can do this, scientists observed their behavior, and surprisingly they have found that ants did not follow back on the same trail they randomly took after they left their nests. Instead, ants took a direct route as if they already knew where the nest exactly located. How do these ants find the closest way and shortest distance to their nest from their current locations? Former studies had found that red and forest ants secrete a chemical substance to mark their paths. They leave a trail of chemical scents or visual traces behind them—like leaving a trail of breadcrumbs to help you find your way home. However, the structure of desert sands and conditions are not consonant with containing chemicals that will carry an odor or leave visual cues. Even if such markings have made, it is hard to guarantee that they will remain intact long enough considering the harsh conditions of the desert. As in Hansel and Gretel fairy tale kids who could not return home for the breadcrumbs they had left on the trail eaten by birds. Therefore, these desert ants must be equipped with another cognitive mechanism so that they can return to their nests before succumbing to the midday heat.  

Black desert ants (Cataglyphis fortis) emerge from their nests in the heat of desert sand, which rises to 70 degrees with the rise of the morning sun, to search for the remains of other insects that were not as heat resistant as they are. They can only survive for one hour on the hot sand and under the blazing sun, which means that within an hour, they must find their food and bring it back home without getting lost. The journey is quite arduous and dangerous each day. If the slightest confusion occurs and they are not able to return to their nest in time, then it could cost them their lives.

Scientists conducted a series of research in the scorching deserts of Tunisia to find out how desert ants take their food to their nests in the shortest route possible. Researchers first determined an anthill and plotted the terrain around it to set up a coordinate plane. They observed that the ants left their nests very early in the morning to begin their daily search for food, and many of them eventually found grubs that had been planted by the scientists. However, researchers moved the ants to locations that they had not previously been to after the ant began carrying the food back to their nests. The attempt was to understand whether there was a “sign placement system” within the ants. This system would encourage the ant to find its last known location, in this instance where it had picked up, then find its way back home. However, the ant instead began heading directly to its nest. It was as if the ant determined its position concerning its nest and set off for it immediately. This experiment was repeated on many ants numerous times and with the same consistent results. The ants, as soon as they had placed on the ground, moved to the nest relative to there. With a wondrous intrinsic coding of some neurons in their nervous systems, they traveled the distance between their new location and the nest in the shortest way possible. In addition to this, the margin of error was very nominal; they found their nests with a ten percent error in the average distance of 500-meters and with an error of only two degrees in angle. Additionally, a fascinating discovery revealed that the ants could calculate errors in their navigation systems. As they approach their destination, they would make adjustments if they need to by moving back and forth in parallel lines to reach the nest with minimum error.

Scientists determined that desert ants have about a thousand lenses in their compound eyes (remember that a human eye has only one lens) and 80 lenses in each of their eyes that can detect polarized light that comes from different points in the sky. Polarized light occurs when sunlight enters the atmosphere of Earth, hits air molecules and other particles, and then scatters in all directions. This dispersion leads to polarization, and the light that starts to vibrate in many planes begins to vibrate in only one plane. Therefore, the strongest of them is a distinct polarization that always makes a 90-degree angle towards the sun. The lens system in the eyes of desert ants uses this polarization to form a kind of Sky Map. These ants will occasionally stop and robotically move their heads while returning to their nest. This brief period allows the ants to make this sky map by surveying the sky and making a mental note of its layout. Researchers believe that ants can then calculate the direction that they need to travel to return to their nest. They repeat this movement along the way to continually update their sky maps. If they cannot find their home, then they utilize a patterned search method with a set of circular motions. It means that each ant knows how far it is from their nest at every point of their journey.

Then, how do ants find their direction to the nest? Perhaps they were guided by the position of the sun in the sky is. To test this hypothesis, researchers placed a set of mirrors to make ants perceive the sun in a different state than where it ordinarily would be. It observed that the ants changed their directions according to the new state of the sun. However, this finding raised another question; researchers wondered how the time of day would affect the ants since the sun moves across the sky during the day. However, this finding raised another question; researchers wondered how the time of day would affect the ants since the sun moves across the sky during the day.

In another part of the experiment, the researchers caught the ants after they found the bait, closed a box over them, and kept them inside the box for several hours so that they could not see the sun and its movements. It expected that the ants would have trouble finding their way back after they were released since a long time had passed, and the sun was in a drastically different position in the sky. However, they once again returned home by using the shortest distance possible. It understood that the desert ants were aware that time was passing even though they could not see the sun.

We now understand that ants determine their direction home by using the sun, but we still do not know how they figure out the distance they must travel to return to their nest. Researchers have developed three hypotheses to explore this phenomenon. The first hypothesis was the energy hypothesis. According to this hypothesis, the ants were able to know how much energy they needed on the way back by calculating it they had spent until they reached their food. The depletion of their energy meant the end of their journey. An ant loaded with extra weights to test this hypothesis as soon as it reached its food. The scientists thought that if their body weight increased, then they would not be able to strike reach the nest since they would spend more energy on the return trip. However, in this case, it did not affect the ants, and they returned home in the shortest way possible regardless of their weight.

The second hypothesis was the optical-flow hypothesis. In this hypothesis, it believed that the ants had visual memory, and this was how they remembered the way back. To prove this, scientists prevented the ants from seeing their surroundings by blindfolding the ants when they found their food source. However, the blindfold did not prevent the ants from obtaining the shortest distance back home. As a follow-up to this experiment, the researchers placed an extensive television screen in front of the ants showing an endless desert on the television screen to make the ants feel as if they had crossed the entire desert in this simulation. They used various types of simulations, but the result did not change; the ants found their way.

The last test involved the pedometer hypothesis. It surmised that ants could be counting their steps to determine how far they had traveled. To test whether they were doing so, researchers attached stilts made of hair strands to the legs of one group of ants after they found the food. As their legs now extended, they could move with longer scale steps. Another group of ants had their legs cut below the knee, thus shortened to increase the number of steps needed to walk the required distance back. They then observed the return journey of both groups of ants. The results were astounding; the ants with shorter legs had concluded their course before reaching the nest, while the ants with longer legs ended up passing the nest. Thus, it understood that the ants counted their steps according to the distance they traveled.

The findings reveal that the ants are created with an internal system that keeps track of the steps they take and re-calibrates itself on the way back. People make these complex calculations with measuring instruments and by knowing the laws of trigonometry. However, these small creatures find their way directly back without using any tools or computer applications. They do not use their perception to find direction, and they do not use any other directional methods because they all remember direction and distance as they move forward. If you look at this situation, what would be your simplest explanation? You can only have one definition: These little creatures can measure distances and angles precisely by applying mathematical calculations and trigonometry within their conditions. Since the first day of their existence, these creatures show only a few of the shreds of evidence of the divine power created them out of nothing with wondrous systems and superior abilities in their bodies.

I have put my trust in God, my Lord, and your Lord. No living creature is there, but He holds it by its forelock and keeps it under His complete control. Undoubtedly, my Lord is on a straight path (He governs all that exists and carries out His decrees rightly and with absolute justice). (Surah Hud, 56)

Ebru, the art of crafting images and pictures with special paints on the surface of water, originated on the continent of Asia, spread to Anatolia, and from there to the rest of the world. Ebru has long been the name given to the original Turkish art of “paper marbling” [1].

Enchanted by their interaction with water, human beings started practicing the art of paper marbling. By practicing Ebru, one may interpret the time on the marbling tray as a sort of time travel in which the wiggles of the water take a journey between the past and the future.

For ages, people have been using long-lasting rock surfaces to transfer information to future generations. These artworks and writings are reminders of past civilizations and they have always gained the attention of mankind around the world.

Some natural ingredients for traditional Ebru art include rose branches, dust paint, bile juice, and gum from a wild licorice plant. This natural combination of each ingredient of Ebru art ensures its uniqueness.

Each careful sprinkle of a color on the surface of the water is the reflection of the emotions that are felt by the artist yet are difficult to express otherwise.

Ebru is a delicate reflection of a civilization in which water is exalted as glorious and precious. It is one of the major elements of our world, that are essential for existence, along with soil, air, and fire. Ebru is the art of enthusiasm presented with sincere feelings.

Ebru gives a new perspective to the world of art and to cultures that are not familiar with it, since the concept of water serving as a base might initially seem impossible.  Throughout history, eastern and western civilizations were established around sources of water. Water in fact attracts human beings to its vibrancy like a magnet. It is the source of life for all the people from different ethnic groups, colors, languages, and religions. The mosaic appearance of Ebru art reflects human diversity in its tank with harmony and coherence [2].

In the past, people used to write thing they didn’t want to remember on water. Anything is doomed to disappear on the surface of water other than Ebru.

Using water as a medium is paradoxical because water signifies change as opposed to permanence. However, embroidery on the surface of the water is not something to be planned beforehand but rather an art form that the Ebru performer comes up with at the moment. A single stroke can be transformed but not reversed.

Once the artist has reflected his or her soul’s shape, and the colors have taken their place, the paper is gently laid on the water.

Ebru is like life itself; even if we think we do the same things every day, every moment differs from the others and is unique in its own way.

Ebru is either in the sky or on the Earth [3];

“O eye, do not sprinkle tears into my heart’s fierce fire, for there will be no way you can put out such a fire.
Is the revolving sky’s color the color of water? Or is it my tears that cover up the sky, I cannot know.”

Those who are interested in the art of Ebru and put their hearts into it will connect with a feeling of spiritual serenity and tranquility. Life in contemporary times is a never-ending wave of turmoil. Those who want to escape the hustle of the routines of life will never be rejected and will be welcomed to the ambiance of serenity by the peaceful waves of Ebru.

It takes people from their own world and brings them to another world of imagination where they can reflect on their feelings and get rid of the negative emotions within them.

For those who are stuck in the modern cycle of never-ending tasks, it is a way for them to reach a peaceful state of mind and relax.

Ebru art might take the artist back to their childhood when they used to play with dirt and mud. Perhaps the lack of preserving their childhood feelings can be remedied.

Ebru craftsmen use the biz, a tool used like a pencil to write on the surface of the water. In Ebru, every move on the water gives color patterns.

The art of Ebru in such a small container can take a human to anywhere that they wish to be or can be a canvas for any image that they wish for, such as a garden of flowers or a limitless sky. It will be anywhere other than any negative emotions inside.

Ebru art eventually makes the performer, as well as those that enjoy it, joyful once it is placed onto the wall of a house or at work and is thus able to begin emanating its bliss.

Have you ever seen a rainbow? Until recently, I had looked at many rainbows, but had never truly seen a rainbow.

In his writings on faith and logic, religious scholar Bediuzzaman Said Nursi maintained that looking and seeing are two different things. In his book, The Words, he says: “The eye is a window through which the spirit looks at this world. If you use it on behalf of your carnal soul, without selling it to God Almighty, by gazing at transient, impermanent beauties and spectacles, it panders to lust and other carnal desires.”

Using Nursi’s reasoning, you might look at a magician who is right in front of you, for example, but never see how a trick is accomplished. The same thing happens when you look at a mathematical equation but don’t see what the x value is – unless you are good at mathematics.

After watching MIT physics professor Walter Lewin’s lecture “The Hidden Beauty of Rainbows,”[1] I am finally able to see the rainbow, instead of just looking at it. To share my fascination about this topic, and reinforce my own knowledge, here are some notes I took during Lewin’s lecture. Walter Lewin is the author of For the Love of Physics. This book is really a perfect book if you love Physics.

Figure 1.0

There are four fundamental facets we need to cover to understand a rainbow (Figure 1.0). The first is the “radius” of a rainbow. Since every rainbow has a radius, this means a rainbow is a circle. And every circle has a center point. A rainbow’s center point is below the horizon. Here, we can ask these follow-up questions:

1.1 How we can find the radius of a rainbow in degrees?

1.2 Do all rainbows have the same radius?

The second question is about the colors of a rainbow, specifically red. If you see a rainbow, there is always a red color. But:

2.1 Is the color red always on the inside or outside of the rainbow?

2.2 Does the position of the red color depend on the time of the day and year?

It’s obvious that light determines a rainbow. If there is a rainbow somewhere, there is an enormous difference in the brightness of the sky above and below a rainbow. We can now ask:

3.1 Where is it bright?

3.2 Where is it dark?

There are some additional questions we need to discuss regarding the second bow in Figure 2, specifically:

4 Have you ever noticed the second bow? If yes, then;

5 Where do you look for the second bow?

6.1 What is the color sequence of the second bow?

6.2 Is it the same as the primary bow, is it brighter, or is it reversed?

Figure 2.0

In order to understand rainbows better, we need to review some basic physics. Let’s start with reflection and refraction.

Mediums, reflection, and refraction

Definition: A medium[2] is the substance that carries a wave from one location to another.

When light goes from one medium to another, like from air to water, one of two things happens:

● Some of that light bounces back, which we call reflection. The light will reflect at the same angle at which it hit the surface.

● Part of the light doesn’t reflect, instead continuing into water at an angle. We call this refraction.

Each medium has an index of refraction, which tells us what the speed of light in that medium is. The index of refraction of air is 1.0003, and the index of refraction of a vacuum is 1.

That means the speed of light in air and in a vacuum is almost the same. That speed is 300,000 kilometers per second, and that’s why the index of refraction for air and a vacuum is 1. But in water, the index of refraction is approximately 1.33. The difference between 1 and 1.33 means that in water the speed of light is 33 percent slower than it is in air.

Snell’s law and an angle of incidence

There is also a connection between angle of reflection, angle of refraction, and the index of refraction. We call it Snell’s law.

Snell’s law illustrated:

Figure 3.0

To understand this formula, you need to know the definition of the sine of an angle.

Definition:The sine[3] is a trigonometric function of an angle. It is found by taking the length of the side opposite the angle and dividing by the length of the longest side of the triangle.

If α is 0°, then sin (α) = 0.

If α is 30°, then sin (α) = 0.5.

If α is 90°, then the sin (α) = 1.

Let’s do an example where we can apply Snell’s law (Figure 4.0).

Light comes from air to water at an angle of 60°. (This is possible, because the angle at which water comes in, the angle β, will be 40.6°.)

Definition: The angle of incidence[4] is the angle between the incoming light and the vertical on the surface.

Figure 4.0

Like professor Lewin said, “very simple, very straightforward.”

Figure 5.0 | Figure 5.0. Example of refraction and reflection. See also [5].[5]

Figure 6.0

Figure 6.0 displays a true wonder of water. Sunlight is coming from the left side, landing everywhere on half the surface of that raindrop. We can choose one very narrow beam of all that sunlight with a 60° angle of incidence. We call the angle of incidence “i” and the angle for the refraction “r.”

Of course, that narrow beam is the only a small fraction of the total.

At point A, two things happen (in accordance with Snell’s law);

● A little bit of light reflects.

● The remaining light refracts.

The light reaches point B inside the water drop. At point B, two things happen:

● Some of the light goes back into the air (signaling refraction).

● Some of the light gets reflected. (Therefore, at point B, the angles are the same, “r.”)

Then the reflected light goes on its way to point C. Here, a little bit of the light is reflected and goes back into the water. Most of it comes out of the water, which results in refraction.

At this point, if we use Snell’s law at point A, the reflection law at point B, and then Snell’s law at point C again, we will see that our angle for the refraction at point C will be, surprisingly, “i.”

Now, if we check the line that comes out from the water at point C, we will have a changing angle. We can call it φ (Phi). And for the angle φ, we have an algebraic formula, as follows:

φ= 4r — 2i

If you check the figure, you will see that we have 4 r and 2 i.

By the way, if we take the narrow beam which passes through the center of the raindrop, we can easily see that the angle of incidence is zero. In accordance to Snell’s law, this narrow beam goes straight through. Then it reflects back and finally it comes out of the water. This is true because:

if i = 0, then r = 0 and therefore φ = 0.

Let’s do something interesting and change the value of “i.” If the light hits the water drop higher up, the angle “i” increases. At some point, the angle φ also increases and reaches a maximum value.

Figure 7.0

If you recall, the index of refraction for water is 1.336. If we take any value of “i” on the table and apply Snell’s law, we can easily calculate values of r. And then, if we use the formula φ=4r — 2i, we can come up with the values of φ. This is illustrated in Figure 7.0.

If this doesn’t seem all that special, there is something else that you wouldn’t expect: φ reaches a maximum value, and when you go to higher values of i, then φ goes down again. This plays a key role in the formation of a rainbow.

The index of refraction depends on the color of the light.

Figure 8.0

As seen in the table, when the angle of incidence for red light is very close to 60°, the value of φ is at its maximum, which is 42.3°. In other words, the value of φ can be smaller than 42.3°, but it cannot be larger. For blue light, the angle of incidence is slightly lower, and the φ maximum is at 40.7°.

Water drop and a cone

A key question arises: Let us say we have one water drop, and the sunlight falling onto that water drop is coming from the left. What is that one water drop going to do with the white light from the sun that covers half of the rainbow?

Let us check first for red light and then for blue light.

Light beams will come out of this drop, and that cone will be filled with red light. But the angle for the light beams cannot be larger than 42°, meaning they can be smaller. Then we will see a cone of lights.

But why is it a cone? Because, if we go back to what was previously discussed, we will remember that one light beam comes in with an angle i, and then comes out with an angle i.

Figure 9.0

Figure 9.0 shows a representation of a water drop. The light that comes in at the angle of incidence is 60°. It refracts and reflects inside the droplet, then goes to point C and comes out of droplet at an angle of 42°. And, surprisingly, if the angle of incidence is 60°, when the light beam comes out, it has to be red light. On the other hand, there is not only one light beam coming in with an angle 60°. The entire surface of this water drop is illuminated by the sun, so there are an enormous number of beams for which the angle of incidence is 60°.

If we go back to Figure 9.0, we see the black line on this water drop. Any light beam that comes in anywhere on that black line will have an angle of incidence of 60°.

Figure 6.1

Now we will do the same for blue light. This time, we will have another cone which is completely filled with blue light, but when the blue light beams come out, the angle will be at a maximum of 40.7°.

Interesting fact: All the colors except for red and blue that are in the sunlight will be in between the red and blue.

Figure 6.2

A journey: refraction, reflection, and refraction

We know that when the light comes in, it goes through a journey. A light beam refracts, then reflects, and then refracts. That’s all. But, how about the light on the right side of the cone? Is there any light? When the sun shines in, does this water drop bring light there?

If the angle φ is larger than 42°, then, yes, it is possible. But we have already proven that the angle φ cannot be larger than 42°. So, it is impossible: There is no light outside the cone.

Another question… What will be the color of the light inside the blue cone? We should remember that the red light is everywhere in this cone, because as long as the angle φ is smaller than 42°, red light can be anywhere. The blue light is also almost everywhere because the blue light is allowed to be smaller than 40°. This means all the colors that we didn’t mention are coming out inside the blue cone and there will be just white light.

Figure 6.3

To summarize, if we have a water drop, and a bright light shining onto this water drop, we will see red, blue, green, white, and other colors inside the cone or circle. In other words, all the colors of a rainbow. And of course, there will be no light outside the cone. There are some experiments on YouTube that you can watch if you want.

Figure 6.4

You may think that at the location where blue comes out, if all the other colors can come out — which they can because the angle is smaller than 40° — the light should be also white, not blue. It is a nice approach, but wrong.

It is wrong, because of the light intensity. If you check the graph for the intensity of the light, you will see that different colors have peak points where φ reaches the maximum value. If all the colors are present and equal intensity, we see white light. That’s why the inside of the cone is white. However, when the color red spikes up, it dominates its location. We don’t even notice the other colors.

Figure 6.5

Looking at the sky

Let’s say you are standing at point A and the sunlight is coming from the left. Since the light comes from infinitely far away, all these lines are parallel to each other. Let’s say you look at the sky in direction B and pick a raindrop at any point. Any point you pick will cast the cone in the direction of the sun with the angle 60°.

When you look at the sky in the direction B, will you see light? You will not, because you are outside the 42°.

Figure 10.0

What if you look in a different direction? We will look at point C (it doesn’t matter where), and take a rain drop on line C. Light beams will do the same thing. Again, they will produce a 42° red cone. However, you will see white light. Yes, you read that right, white light, because you are looking straight in the middle of the cone of white light.

Let’s say we choose another angle and look at point D. If we choose a raindrop anywhere on line D, it will make no difference. It will cast into the sky the famous 42° angle because that’s the angle that was chosen there. If we look in that direction of the sky, what will we see? Yes, only red. No other color!

Figure 10.1

And now, we know where we will see red light, blue light, or white light. And we also know which direction has no light.

A rainbow is a bow in the sky

Let’s suppose the sun is on your left and you are standing at point A (Figure 11.0). Since there is light, you will have a shadow on the ground. As long as you look 42° away from any direction, you will only see red. That is because a cone is a spherical object. And that explains why the rainbow is a bowl in the sky. As long as it is 42° away from a line in any direction, you will always see red light. And if you decrease the angle, you will see the other colors in the sky.

And so now, we can make a picture of a rainbow.

When we look at the horizon, sometimes we see a rainbow. And we will have a center point somewhere below the horizon. The radius with 42° has red light. The blue light is closer to the 40° radius. This tells us that the red bowl is always on the outside and the blue light is always on the inside. That’s what we always see.

Figure 11.0

Double Reflection in the Rainbow

We can also include two reflections in the rainbow. If we do, we get refraction, reflection, another reflection, and then another refraction. So, the light beams reflect twice. And if we do this hocus-pocus again and again, we can come to a conclusion: There is no maximum value for the various colors, but there is a minimum value. In other words, various colors cannot be lower than a certain value, but they can be higher.

And if we do some calculation for the angles, we will see something very similar. We will find out that the second bow is pointing at the sky, and the angle is 10° above the first one (which is 52°). And, surprisingly, the colors of the second bowl reverse. In other words, red is the one on the inside, and blue is on the outside this time.

Figure 11.1

Interesting fact: There is no light between the two bowls. This is because of the φ maximum and minimum. We call that dark part Alexander’s dark band.[6]Additionally, since the second bowl is formed by φ minimum, sunlight can come out at angle φ or larger and there will be sunlight above a rainbow.

Figure 11.2

Some examples…

Image 1: René Descartes’ sketch of how primary and secondary rainbows are formed (probable engraver: Frans van Schooten the younger).

Image 2: This diagram was drawn by the famous physicist Newton who was one of the first to understand the rainbow, from his book Optics.

Image 3: Double rainbow. The primary red bow is on the outside, and blue is on the inside. Alexander’s dark band can be seen in between the two bows. It shows up really dark. For the secondary bow, red is on the inside, and blue is on the outside.

Image 4: Walter Lewis’ backyard and his rainbow. When you water your garden when the sun is high in the sky, you can get a rainbow all the way around you. 42° away from the line is always red. If you turn around and look back, it is red.

Image 5 | A white rainbow. It is very unique and rare. It is also called a fog bow, because fog has small water droplets that create this effect.

Image 8 | Red rainbow. Let us imagine that there is a rainbow at sunset. What would you expect to see? We would only see red light because there is only red light. What would happen to the white light inside the bow? It would be red too.

No matter how fast or how far a person runs, the horizon will always be beyond them. This being the case, the real distance and depth of the horizon is inside a person, it is in their mind and perception…

A race I will always remember

Not too long ago, when I was still a little boy, I found myself running from my father’s village to my mother’s, and from my mother’s to another and to another, in the hope of catching up with something that was neither a ball, some other toy, nor a bird, but rather the point, the line where the sky seemed to touch the earth. We call it the “horizon.” That line, that “place,” first presented itself to me hiding right behind the trees to the left of my father’s house. I started out that day walking rather leisurely because the distance between me and the horizon seemed so short. When I observed that the sky had moved, or rather seemed to have moved further away, I hastened my steps. Then I noticed that the sky moved further and further away. Well, being determined to reach the place where the sky certainly touched the ground, I kept walking faster and faster until I found myself running.

I ran for quite a while until I realized that “there”, where the sky and the earth met, was still further away, that it would take me more time and effort than I had thought. I went back—I had to go back—to my father’s village, back to my usual village life because I saw that perhaps much more was involved, that maybe much more effort was called for in order to achieve what I desired, namely, to get to the point where I could touch the sky, where I could climb the sky. I went back to the ordinary, the normal life and experience of the village and of my people. But I did not tell anyone, I did not discuss the experience with anyone, even though I did not stop and could not stop thinking about it. I thought to myself that perhaps a week, a month, maybe a year would suffice for me to reach the place where the sky and the earth embraced. I was absolutely certain that right there in front of me, over there, not too far away, the sky touched the ground. And I thought that perhaps all I needed to do was keep walking, keep running, and keep racing forward, without stopping, without interruptions, without distractions in order to get to where the sky kissed the ground.

Today, thirty-five years later, I have realized that I was not wrong. I was right. The sky did touch the ground. It touches the ground all the time. You may ask “but where and how?” The sky touches the ground in our perception. Look across from your window into the distance. What do you see? Or, go outside and look in the distance. What do you see? The sky is right there, over there, touching the ground, the road, the houses, the trees, the mountains, the sea, and remaining there. But keep in mind that this is all happening in our perception. In perception, things are the way they appear, the way they seem. No rigorous, critical thinking is involved. And this happens so many times, and in fact is happening now; it happens every time that we are not thinking deeply, with attention and effort. It happens every time we fail to allow other perspectives, other possibilities and other possible interpretations to emerge.

The sky touches the earth, embraces and kisses the ground, right there in a fixed position, as long as you do not move. Once you move, it moves. And when you run after it, it too runs, not towards you though, but rather away from you. If you stand still, it stands still. If you stay where you are, it remains where it is. If you move even an inch, it will move. It will never allow you to catch up with it, to touch it; it will never allow you to possess it, to tame it; it will never allow you to take possession of it. And yet, it is always there, “putting everything into perspective.” By that I mean the horizon enables us to see, for without horizon one cannot see much of anything. Think about it! Everything presents itself in horizon. Everything dwells in the horizon, everything is within the confines of the horizon, and depends more or less on this phenomenon. And if I may borrow an expression from Saint Paul’s speech at the Areopagus (Acts 17:28) and be at liberty to use it as I see fit in this context (just as some scholars say he himself was at liberty to do with the same expression from the writing of Epimenides of Knossos (6th Century B.C.)), one can say that “that in which we live and move and have our being” is the horizon.

Standing still, remaining in one fixed position is not in the nature of the horizon. Its every stop (or what appears to be its end, its boundary) is temporary and transitory, like a pilgrim’s stop on a journey whose destination is still far away. It keeps moving, and it invites us to keep moving too, keep working, keep meeting people, keep exploring, keep digging, keep sowing, keep cultivating, keep harvesting, keep looking, keep reading, keep writing, keep thinking, keep talking, keep wondering.

We hear, not infrequently, the expression, “on the horizon/in the horizon.” What does it mean? It means in view, in the possible future, in sight. That which is in or on the horizon appears close, and seems to be approaching; it is as if it’s right there among the things that one hopes to do soon, as something squarely within one’s reach, among the things that one’s abilities can handle. What is in the horizon, then, is something that appears “present” and seems quite achievable.

What is a horizon? And what does it do?

A horizon is inseparable from a living, perceiving human being who is in the open or in the frontier of the open. There are no horizons in closed spaces, closed places. The distance between a living human being and the line where the sky and the earth meet is very wide. It is infinite. It is far, far away. You can only measure it with your eyes, your mind and your soul. You can figure out how long it is only to the extent that your eyes, your mind and your soul can go. An application of any other measuring device will only frustrate you because the moment you start going after it to measure it, it will recede. But the truth is that what you are actually seeing of the horizon is only a small part of it. The bigger part is on the other side of the horizon. Every horizon has at least two parts: a front and a back. The front of the horizon consists of the part you are seeing, and its back consists of the part hidden from you because of the hills and mountains, the earth, the road, the trees, the sea. In fact, the line where the sky seems to touch the earth is really only a perceived curve or a perceived point of contact, but the horizon really goes far and farther away, without end: it stretches into infinity.

All the things we are seeing are in fact standing in the way of the horizon. Similarly, all the things we are thinking right now, all our thoughts and ideas, everything that is presently on our minds can be an obstacle to a deeper and fuller understanding and appreciation of the horizon. We have to let go of all of these things in order to begin to have an idea of the depth and richness of the horizon.

For now, let us focus on the part of the horizon that is visible to us. It is a world, the world that we live in or would like to live in. Normally, it consists of people, people of different religions and/or of no religion at all, people of different languages and cultures, different experiences, different states and walks of life, different situations and aspirations, people driven by different desires, values and visions, people of very deep opinions, inspirations, beliefs and deep convictions other than our own, people heading in a thousand and one directions. This world, this visible side of the horizon also includes animals of many different types and habitats, which eat different kinds of food and have different spans of life. It also includes many different trees, bushes and flowers, and different types of grasses, etc. Mountains and hills and valleys too, rivers and big oceans, streams and creeks, are all part of this side of the horizon. Small and big houses, low and high buildings, shelters and palaces, mud houses and ghettoes are all part of this side of the horizon that we are seeing. But we do not actually see everything that we know is out there, that is all around us, that is over there in front of us…

How do we even know that there is anything out there, that other people are out there? A long walk, travels, meeting people, doing business with people, education, etc. confirm that there are other people out there, other lifestyles, other ways of thinking, other ways of doing things, other attractions, other things that people consider as very precious and worth dying for. We read about these things, have actually met and seen them with our own eyes, have lived with people of different orientations and values, have had some great opportunities to exchange ideas with them. But neither our reading and studying nor our investigative and explorative eyes can exhaust the visible side of the horizon because even the visible side has its own invisible aspects and invisible faces. Let us take for example persons, situations and objects.

From time to time, a person whom I have known for many years, not only surprises me, but also seems to be a surprise to herself/himself whenever s/he says something or does something I could never have thought or imagined her or him doing. And people of this nature are not uncommon.

How about situations? They are similar. Even the most familiar situations often have aspects that are new and different, which we can see if and when we look with more attention and care. And the moment we become used to these, even newer different aspects of the same situation emerge. The same goes for things such as books, clocks, chairs, doors, and so on. A book often presents us with information that we did not see the first time we read it. And if you read it again, you will again see something you missed the second time you read it. If you wish, you can read it again and again, and you will see something new every time. The book will never fail to make you see something new and/or think something new.

Can a chair or a door do something similar? That is, can a chair or a door make you see something new or think something new every time you encounter them? Let us see. A chair, unlike a book, seems to have no generative power. It seems mute and sterile. But can a chair speak and make us think? The answer is yes, it can speak and make us think. No one would disagree that the chair of Pontius Pilate, the chair of a Court Judge, the chair of Saint Peter, and so forth do have a powerful message. Although these chairs I have cited are special, every chair can say something to us and really make us think. For example, chairs for children and for adults make us think different thoughts, which by the way, make us give children appropriate chairs and to adults what is suitable for them. If we did not think differently of these chairs, chances are we would give adults the chairs meant for children and vice-versa, or give the same kind of chairs to everybody, children and adults alike, seriously compromising comfort. And some chairs would even fall apart (that is, if children’s chairs are given to heavy people like me to sit on).

Doors too make us think. For example, the Door of No Return in Goree Island in Dakar, Senegal, and the Door of Hope in Johannesburg, South Africa, makes every visitor think. But again, although these specific references are special, every door, including those that may seem unimposing and insignificant, can really make us think. Every door has a message.

The bottom line is that even the most visible side of the horizon can have aspects that may not be totally obvious and immediately accessible. Therefore, the visible, that which seems completely clear can still make us think because it often has layers, folds, dimensions, messages that lie beneath its surface. There are always other meanings, other messages behind the obvious. And the moment we finish harvesting one message, the moment we finish reading one meaning, the horizon presents us another one, and yet another, and so on and so forth. Inexhaustible indeed, this horizon can constantly give new meaning, hope, color, shape, style, texture, depth, taste and strength to our lives for endless joy and delight, even under very difficult circumstances. Why? Because the horizon has power to liberate us from the present, the immediate, the obvious. As it draws back, so to speak, that is, when we attempt to respond to its invitation into the open, when we dare to go after it, go with it into the deep, when we allow ourselves to move with it and flow with it, then it can open new doors, generate new ideas, launch new beginnings, reveal inroads, illuminate new bridges, disclose exits, uncover new faces, make terrains of other possibilities visible, make cooperation and collaboration possible, make teamwork possible, bring along other solutions, other fertile soils. With the horizon, there are no closed doors, no human being is a finished project, no done deal, no finished once-and-for-all discussions, no insurmountable barriers. The horizon’s open field stretches into infinity.

All of this is but an invitation to read between the lines, i.e., “to resist simplistic interpretations that dogmatically ascribe fixed significations to [things]” (G. Weiss, Refiguring the Ordinary, Indiana University, Bloomington, 2008, p.58).

It is about the need to go on researching other possible meanings and interpretations of a text, to go on searching for other possible answers to certain problems, to appreciate the expanding limits, and to devote more time and energy to the lifelong project of exploration of self and of the world (and of God) (see P. Okogie’s “Horizon: the birthing world” in the Journal of Horizons of Horizons, Vol. 1, no. 1, Duquesne University, Pittsburgh, 2012, p.10).

Not long after, I saw a minuscule thing coming to me from that direction; I thought it was a bird of some kind. Strange enough, the bird came to me so abruptly that I heard its sound only after it passed me… Guess what? It was not a bird; it was a fighter jet. This time, I knew where to look, and I followed it for the short while it played pick-a-boo with me.

The following day, mom took me to the celebration arena for a national day. I couldn’t believe my eyes, everywhere was full of fighter jets; but my eyes looked for the one that mesmerized me the day before. And, it was standing right there, waiting for me to come. I approached it with respectful steps, and carefully touched it. It was so cold and tough, yet so beautiful. That day, I knew what I wanted to be when I grew up. The smell of the jet fuel coming from the engines was so powerful that even I could fly with that kind of a drink.

“Hey; come here” I heard someone calling me. There was really nobody around. “Follow the sharp smell, come on here,” insisted the voice. Was I daydreaming, or had I been poisoned by the jet fuel and lost my conscience? Yeah, yeah, the voice was coming from the rear-end of the engine. It was the nozzle that was talking to me.

The moment I realized who was talking to me, I found myself in the circular, hollow structure of the nozzle. I was too nervous and surprised at first, but after a moment of looking around admiringly, I spoke with the words: “I know the inferno fire that you are exhausting. Isn’t it beautiful? You are so powerful. You are the one that is powering this beauty in the sky.”

The nozzle was not happy to hear my words of flattery. “Hey little boy, you know something, but you don’t know everything. Yes, it is true that I am exhausting that violent river of gas. You are right that this stormy exhaust is in the heart of this beauty in the sky. But you have got to learn more. I am only a solid duct that is accelerating what comes into me. I have no power to compress that humongous amount of air into a volume as small as a bird’s nest. I am completely unable to heat up the air to inferno level. And, the beauty in the sky is not taken up there by me either.”

I was totally disappointed and frustrated by the nozzle. I had thought for an instant that it was my hero; but now, my dreams were destroyed. I felt all alone in a desert. The nozzle must have realized my situation, so it picked up again: “Come on. I am going to introduce you to the unseen heroes behind our mysterious beauty. I am going to show you the inside.”

I was truly perplexed. What else could be more mysterious than a speaking nozzle? The voice of the nozzle slowly diffused into the deep and dark hallway into the engine, and I followed it. Soon, I came by long towers that had a nicely curved shape. As soon as I stepped near them, the floor that the towers were built on started moving. In the midst of this earthquake and a blinding darkness, I could faintly see another row of towers that were stagnant. I threw myself towards them. As I was dealing with my horrified and troubled soul, I heard a thunderous voice that reverberated everywhere:

“How nice to see you here, Adam!” I was doubly shocked. Not only was this unseen thing talking to me, but it also knew my name. “Do you know me?” I replied. “How could I miss your glittering eyes fixed at us whenever we pass over you? I am the turbine, one of the unseen heroes. I am the one that powers the compressors that squeeze the air. I am the one that faces the hot air before it goes into the nozzle.”

Wow, this was the man; this was the legendary hero behind the beauty in the sky. I looked at its towers that displayed nobility and their curved surfaces that embodied beauty. As I was losing myself in admiration, I heard the voice again:

“These are the eyes that I have been seeing every time we passed over you. But I have to tell you something. What you are looking for is not me either, because I cannot create the hot air that energizes everything, including me. Despite the beauties and power embodied in me, I am not the essence that bears the real beauty you are looking for.”

What was that supposed to mean? First the nozzle, now the turbine; every time, I am being attracted, and then I am left alone with a sense of deception. Are these heroes making fun of my admiration of their beauty? If so, they don’t deserve my admiration anymore; if not, then why am I having this feeling of deception? Is it wrong to attribute hero status to something?

Lost in feelings and thoughts like these, I left the turbine, and proceeded further into the darkness. Not only didn’t I know where I was, but also I had no means to determine my whereabouts. In total silence and darkness, I sat at a place that felt like a smooth and large room. Suddenly, a wind started blowing with growing speed, and a constant noise occupied everywhere. I was alarmed and sought somewhere to cling to. With the help of lightning that seemed to come out of nowhere, I saw a cavity that looked safe. After a challenging crawl, I was there. Then, a second lightning came and everywhere burst into fires. As if winds from the hell were gushing out. My jaw dropped down, I stared at this miraculous display of fire.

“Welcome, finally you are here,” told a voice that was distinctly heard despite the violent storm. I felt like I am being driven through a scenario so that where ever I enter, I experience things that I was meant to. “Am I the hero of this scenario?”, I asked myself inside, and laughed at the idea. Upon seeing so many extraordinary things, my awe of the strange things was veiled with habituation. So, I couldn’t pay the respect that was due the voice I heard. Maybe because of this, I received a kick from behind, and I had to struggle against the winds of fire to get back to my seat where I was safe and comfortable.

“Hello, are you still there?” I asked. “Can you tell me where I am?” That distinct voice appeared again in my ears: “Indeed, I am here, but you weren’t!” I bowed my head with shame. Having hurt the only one that could help me in this situation was as foolish as it could be. “And I was with you all along from the start.” What was this? I didn’t know whether to feel ashamed because of my selfish and pragmatic sense of respect, or to burst into a thousand pieces for not having recognized the one who has been with me all along?

“This is as far as you can go in this story. You are in the place where the energy that empowers everything is revealed. It is the heart of the beauty that you have been admiring.” After a second of silence, “Did you find what you were looking for?” asked the voice. I had seen strange things, but none of them had satisfied my heart nor quenched my curiosity. A sad face was my response to the question, but I didn’t know if the voice could see my face. Apparently it did, so that it directed me to another place. “You see this violent fire going on, would you like to fly away with it?” Was this guy crazy? How in the world could I survive in fire? “Well then, there are two ways to get out of here. Either you go along the fire back to where you came from. Or, if you are not able to do so, you go forward.”

With that directive, I started crawling towards the front, into the strong wind. I came across a thing similar to the turbine, and then another hallway similar to the nozzle. At first I was puzzled, because I had seen the same things that I had seen on my way previously. Had I made a mistake and proceeded backwards? That mustn’t be the case, since I had moved away from the fire.

After this stupefying similarity, I was at the mouth of the cave where everything starts. I was able to see the wings too. But now, the aircraft was moving. All of the storm that was going on inside was for accelerating. The force of the acceleration was so strong that I slipped from where I was clinging, and found myself stuck at the beautiful front curve of the wing. Strange enough, the same voice welcomed me again: “Finally you are here.” I didn’t know whether to reply to it or to lose myself while watching the beauty of the aircraft as it soared into the air with an ever increasing speed. It definitely felt like the divers who hear that beautiful voice when they go deeper than they should. I could not resist melting my body in the excitement of the maneuvers. After a while, we were hundreds of meters above where we had started. Now, the aircraft was cruising, and despite the rareness of the experience, it felt like sitting in the living room. With the steadiness of my state, I found myself emerging from the depths of excitement.

“Have you found the beauty you are looking for?” asked the voice again, to which I said yes. “Where do you think that beauty is coming from? From the engines or from the wings?” That question was most unexpected. The engine itself was not able to fly, it was only able to create a strong push. The wings were only beautiful. They did not actively do anything. They only stood there in the wind, and then, lift was there. Without the air, the wings would not create anything. As for the air, we are completely sunken in it, let alone flying. “I don’t know where the beauty is coming from. There seems to be something missing in the ingredients that created the beauty of flight. None of the ingredients seems to originate it. It looks like you put the engine, the wings and the air in the pot, and suddenly something that you did not put comes into being.”

“But you did not realize this point until you made this journey, despite that you have been witnessing the same beauty all along. “

Why was that the case? Why did I have to make this incredible journey in order to become aware of this uncertainty in the source of beauty?

“When you are not actually in a journey like this, you take all the mysteries for granted, because you consider them natural, ordinary. But once you are in the journey, you realize something different that exists neither in you nor in the things you come across. It is as if somebody is tracking what is going on, and whenever the necessary ingredients are there, he secretly adds the missing spice into it at the right amount. And, then? Behold the beauty!”

Day and night I burn gripped by agony, You are the One I need

I find no great joy in being alive; if I cease to exist, I would not grieve,

The only solace I have is your love; You are the One I need

Your love slays lovers; makes them dive into the sea of love

Fills them with the image of God; You are the One I need

Let me drink the wine of love; like Majnun, live in the mountain of hardship,

Day and night, You are my sole concern; You are the one I need

The Sufis seek for friendly conversation; the Akhis look for the hereafter

Majnuns (lovers) seek for their Leylas (beloved); You are the One I need

Even if, at the end, they make me die; And scatter my ashes up to the sky,

My soil would break into this outcry; You are the one I need.

Yunus Emre, the mystic, is my name; Each passing day rouses my flame,

What I desire in both worlds is the same; You are the one I need.

Yunus Emre is a famous sufi poet who lived in Asia Minor in the thirteenth century.

There is explicit information in the divine scriptures that the Great Flood did take place, and that it was a divine message to humanity. About these two points, most of the members of the three Abrahamic religions, and even members of many other faiths, do not have a problem at all. But if we want to draw detailed information about the flood, then we see many topics of discussion: was it a local or global flood? What were the number and kinds of animals in the ark? What was the size of the ark? What was the date of the event? And so on.

In the Qur’an, we are not given all of the details of the flood event. In fact, we should not expect to find all of the details in the revelation, because its primary goal is to inculcate love and respect of God in people, not to teach them science or history. So, from a religious perspective, details such as whether the flood was local or global, whether the ark was powered or not, etc., are irrelevant. What matters is that human beings are not left to their own in this life, and that they have a responsibility towards their Creator. What is more, if dealing with such undisclosed details is diverting us from the main point, this means we are being blinded by what we think we know; not illuminated. Maybe, this is why we are not given in the Qur’an those details. So, one needs to be careful in this regard.

However, keeping the mentioned warnings in mind, for a person eager to discover other signs of God that are invisible at first glance, the doors of study are wide open. Accordingly, when scholars set out to make a complete picture of the Great Flood based on the information from the revelation, at times they rationally fill in the missing details, or interpret already existing ones. And this is exactly where the discussions start.

In this article, it is our intention to make a brief analysis of the Islamic sources on this issue. In doing this, Qur’anic verses [1] and the exegesis of these verses by three prominent Muslim scholars from the classical and modern era (Hamdi Yazir, Fahr al-Din al-Razi, and Ibn Kathir) are going to be our main references. Then, with the knowledge and comprehension of a contemporary mind, the suggestions of these scholars are going to be scrutinized, again based on the information from the Qur’an [2]. Our aim is to show that there is still room for discovery in the story of the Great Flood, that there probably are other signs of God not revealed so far.

Before we begin, we also would like to underline what is not our intention. Just as in the case of a miraculous feeding of hundreds of people from a bowl of food, it is nonsense to discuss what quantum mechanical processes might have led to such a result, it is similarly futile to try to entirely explain the Great Flood in a cause-effect chain. If something is a miracle, it means that God performs it out of the confines of His practice [3] (what we call as “God’s customs” are referred to as “cause-effect chain” by some scientists). But if it is not a miracle, such as the presence of the little amount of food initially in the miracle of abundance, then it can be scrutinized in terms of God’s customs. Therefore, while discussing the Great Flood, we need to keep in mind this criterion to distinguish between its miraculous and customary parts.

Another point that is not intended is to shake the reliability of scholars in religious matters. Those scholars had not only the best and sincerest of intentions to understand the revelation, but also the fear of God lest they misrepresent the content of the revelation. So, the discussion in this article should not invalidate the reliability of the scholars in essential matters of faith, since our discussion is focused on secondary issues rather than primary ones.

Having outlined what is intended and what is not, let’s start.

Persisting questions

Based on different combinations of interpretations of the existing information from the Qur’an, you could derive several variances of the Great Flood. In this article, we are going to briefly question the prevailing flood scenario suggested by scholars.

Was it a local or a global flood?

There is still debate about whether the flood was local or global. Let’s analyze the two cases, starting with the global scenario. When we say global, it is not necessarily a flood that is covering the entire surface of the earth, but rather the majority of it, and also it affected the entirety of humanity. Conversely, a local flood is one that affects a minor part of the earth and only a part of humanity. In this regard, the prayer of the Prophet Noah calling for the destruction of the unbelievers is taken by some scholars as a sign for a global flood.

Noah also said: “My Lord! Do not leave on the earth any from among the unbelievers dwelling therein.” (Noah 71:26)

One can say that his prayer does not necessarily point to its fulfillment, and this is a fair objection. But, when Noah prayed for the salvation of his unbelieving son, a relatively minor issue, he was corrected at once, and we are informed about it in the Qur’an:

Noah called out to his Lord, saying: “O my Lord, my son was of my family, and Your promise is surely true, and You are the Most Just of Judges.” (God) said: “O Noah he is not of your family. He is one of unrighteous conduct. So do not ask of Me what you have no knowledge of. I admonish you so that you do not behave as one among the ignorant.” (Noah) said: “O my Lord! I seek refuge in You, lest I should ask of You what I have no knowledge of. And unless You forgive me and have mercy on me, I will indeed be among the losers.” (Hud 11:45–47)

One would think that if God is telling us a correction to a minor issue, He would certainly let us know about a correction to a major issue. The fact that such a correction is missing can be understood as the fulfillment of the prayer. So, in this regard, the Qur’an contains information that can lead to a global flood scenario [4].

If we consider the local flood scenario, first of all, we see that it, too, has support from revelation. According to a verse in the Qur’an, Noah was not a global prophet, but was only sent to his people (Noah 71:1). If the flood came due to his situation among his people, only those who are in his community should be affected. Thus, it was a local flood.

Another detail supporting the local flood idea is the way Noah was consoled by God before they went out of the ark after the flood.

He was told: “O Noah! Get you down in peace and safety from Us, and with blessings upon you and upon the communities who are with you. Communities – We will provide for them to enjoy themselves for a term and then there will visit them from Us a painful punishment.” (Hud 11:48)

Looking at this verse, Razi concludes that Noah was worried about how they are going to survive after all that happened. And so, God consoled Noah telling him to go out in peace and abundance. Such peace and abundance would not be possible in a place that was totally devastated by the flood. Aside from this, the same verse has a reference that can be interpreted as the sign of other communities on the earth after the flood. These clues altogether support a local flood scenario.

How about the animals in the ark?

Information from the Qur’an about the gathering of the animals is as follows:

Until the time when Our command came and the boiler started boiling over, We said: “Embark in it a pair of each kind, and your family, except those against whom Our sentence has already been passed, and those who believe.” And those who believed with him were few. Noah said, “Board it! In God’s Name be its course and its mooring. Surely my Lord is All-Forgiving, All-Compassionate.” (Hud 11:40-41)

There are several questions, however, about the involvement of the animals in this story. These questions are mainly due to the assumption that there were thousands of animals on board.

If we assume that there were thousands of species on board, the first question is “how did thousands of species get together?” Is it just an obvious miracle that Noah calls the animals, and suddenly all of the animals start rushing to the ark? If we assume that they were somehow collected, how is it possible that animals which live in totally opposite climate conditions could survive in the ship? What kind of an ark can contain hundreds of thousands of different animals on board? How about their food, was the ark big enough to contain sufficient food to feed thousands of animals for a long time? Considering the small number of believers on the ark, how were the animals cared for? Were the animals free to wander around in the ark? How come they did not create terror in there or devastate it? How were hygiene conditions met while all those creatures coexisted in the same place with humans?

Contrary to the number of questions listed above, there is no information in the Qur’an about the state of the travelers while on board. Can the absence of such information point to something else that we are missing, for example another miraculous event while in the ark that can answer our questions?

Was the ark a sail-type or was it powered?

Some contemporary Islamic scholars claim that it was powered by a kind of steam engine. This conclusion is arrived through the Qur’anic phrase “farat-tannur” (Hud 11:40–41), which means “a boiler that is boiling over.” But this conclusion of the Muslim scholars also entails several questions.

A ship does not need an engine if it is only meant to float. As long as it has hydrodynamic stability and structural strength, it can do the job. Let’s say the engine is needed to maneuver the ship according to a predetermined route. However, there is no clue in the divine descriptions for the presence of such a route. Furthermore, one verse in the Qur’an clearly reports that the route of the ark is up to God (Hud 11, 41). Then, why is the engine needed in the first place, even if it did really exist?

As a result, we are left with this mind-intriguing phrase “farat-tannur,” which needs a meaningful explanation. Whether Noah’s ark was powered or not is still uncertain.

What is the clear sign for all worlds?

In the Qur’an, we are told that “it is a sign for all worlds – ayatan lil alemin” (Ankabut 29:14–15) [5]. Scholars tell us that the pronoun it could either refer to the ark or to the flood. However, the things that are attributed to a “sign” in the Qur’an are obvious things. If we assume that the clear sign for all is the ark, then it must be available to us for it to become a sign. So, it is unlikely that the sign mentioned in the verse is the ark.

On the other hand, the pronoun it could refer to the flood story as the clear sign for all, which is currently more plausible than the ark being the sign. But, there are several other destruction stories in the Qur’an which could potentially be a clear sign for all. What makes Noah’s story so special aside from the others so that only it is mentioned as “a sign for all,” and a separate chapter in the Qur’an is reserved for it? This question becomes even more pronounced if the flood was only a local one. How come a local flood involving limited number of people is so distinct from the other destruction stories, and can become a clear sign for all until the end of time?

What is the water of the sky, and where is it coming from?

The start of the flood-related events is explained in the Qur’an as follows:

So We opened the gates of the sky, with water outpouring; and We caused the earth to gush forth with springs, so the waters combined for a matter already ordained. (Qamar 54:11–12).

There are several curiosity-arousing points in this explanation, some of which are mentioned below.

The distinctive explanations for the two waters given in the verse bring the question whether this rain water could be an unusual one [6, 7]. Curious enough, the literal translation of the quoted verse says “the water met,” not “waters combined.” Some scholars say that such singular mentioning is due to the fact that water is a single entity whether its origin is a spring or rain. However, if we consider the water of the sky as something other than regular water, then the verse becomes literally explicit, because it is actually only the water of the earth that is meeting something from the sky. According to the rules of interpreting the Qur’an, such literally explicit and rational meaning is preferable over an interpreted one.

Second, the gates of the sky are told to be opened by the coming of the water, not “the water is let go by the gates.” Along the same lines, in the Qur’an, the explanation of the events of the end of times involves an opening of the sky. Could gates of the sky have anything to do with events other than just rain?

An interim solution

A scenario suggested by Islamic scholars that can resolve several of the questions stated so far assumes that the humanity at the time of Noah was not much populated, and was a single tribe [8]. Thus, a local flood that threatens the small human population does not necessitate the gathering of all of the animals on the earth. Instead, only animals sufficient to sustain the life in the immediate aftermath of the flood are gathered in the ark. The people around Noah would step on land and make their living from these animals, and as time goes by, the rest of the animals elsewhere on the earth would re-populate the once-flooded regions.

However, this local flood story brings with it some problems. If it was a local flood, and if the ark was only large enough to contain a few believers and a few animals, where is the greatness of the Great Flood, where is the clear sign for all worlds? What is the big deal with the water of the sky and earth, if it suffices to have a local flood, which can even be achieved with regular rains? Why did God explicitly give the instructions for the construction of the ark to Noah, if it is a local flood that people could survive by a regular ark?

Conclusion

The discussion presented in this article shows the gist of the debates surrounding the idea of the Great Flood. Yet, despite hundreds of years of study, there is no satisfactory scenario that can answer all these, and possible other, questions. In any case, what we know for sure is that whether it is a global flood or a global warming, we should not wait for clear signs to appear in order for us to obey the Lord of the worlds; because when they appear, it may be too late.

Notes

1 The translations of the Qur’anic verses are taken from Ali Unal’s The Qur’an with Annotated Interpretation in Modern English, The Light Inc., NJ, USA, 2006.

2 For certain points in the discussion, we are going to provide supplementary information from the Old Testament that is in agreement with the Qur’an.

3 Erdin, M., “Are Religion and Science Compatible,” The Fountain, Issue 49, Jan.-Mar. 2005.

4 According to the Old Testament, the flood was global and was large enough to cover the entire surface of the earth, including the high mountains (Genesis 7, 11-20).

5 “Ayeten lil alemin” is only mentioned twice in the Qur’an. The first one is about Mary and Jesus’s miraculous birth from her (Anbiya 21:91), and the second is this one about the Great Flood. The phrase ayeten lil alemin is usually translated as “sign for all people”; but all people can only be a subset of what alemin really means. A similar phrase, rahmatan lil-alemin, is used for Prophet Muhammad, peace be upon him, in the Qur’an (Anbiya 21:107). Hamdi Yazir interprets this phrase as “mercy for all existence.” Ali Unal interprets the same phrase as “unequalled mercy for all the worlds.” So, it is fair in the context of the Great Flood to scrutinize the meaning of “sign for all people/worlds.”

6 It is curious that both in the Old Testament and in the Qur’an, water of the sky is distinctly mentioned aside the water of the earth. In the Old Testament, we are first told about the creation of the water of the sky (Genesis 1:6-8). When the time of the flood comes, the windows of the sky open (Genesis 7:11), and the flood is realized by the cooperation of the water of the skies and earth.

7 Two independent references to this end are a verse from the Qur’an and a hadith, given here respectively: “His (God’s) throne on water” Hud (11:7), “heaven is a sea whose waves have calmed” (Tirmidhi, Tafsir al-Surah 57/1; Musnad, 2/370). In both of these instances, the implicit or explicit use of the concept of water cannot be the water we drink.

Solar radiation is unpolarized before entering the earth’s atmosphere. Unpolarized light is a mixture of photons having randomly oriented electric fields. According to the simplest theory (Rayleigh), when unpolarized sunlight scatters from atmospheric constituents (gases, aerosol particles, water droplets, ice crystals), it becomes partially polarized, depending on the scattering angle – the angle between the incoming (direct solar) and outgoing (skylight) rays. Unpolarized light can also undergo polarization by reflection off of nonmetallic surfaces such as asphalt roadways, soils, racks, snow fields and water. Therefore, there is an abundance of polarized light in natural environments in various forms. Recently, it has become apparent that animals can take advantage of these rich sources of information in the underwater world, on the water surface, and in the terrestrial habitat that are of celestial polarization patterns. They utilize this polarized light prevailing in their visual worlds in various ways associated with their behavioral tasks like navigation, communication, mate recognition, eggs laying, detection of water surfaces, enhancement of visual power (similar to colors), or perhaps even camouflage.

The skylight compass

The best understood use of polarization is the skylight compass of insects. The orientation of the electric field changes with the position of the sun. This can make the sun as a compass usable even when the sun is obscured. In 1949, Nobel laureate Karl von Frisch discovered that when the sun is not visible, honey bees can orient their flights and communication dances by means of the extensive patterns of polarized ultraviolet (UV) skylight¹. For clear sky, these patterns are quite regular and depend so strongly on the position of the sun. It is amazing to see how these little hard-working creatures come programmed to use them to calculate the sun’s location.

Since von Frisch’s pioneering work, several other researchers investigated polarization vision and found that the polarization pattern of the sky offers many other insect species (desert ants, dung beetles, field crickets, and house flies) a reference for visual compass orientation². For example, desert ants were shown to make long and tortuous foraging walks, but use the sky polarization pattern to return to their nest on a straight line³. They are able to continuously compute their present location from their past trajectory and, as a consequence, to return to the starting point by choosing the direct route rather than retracing its outbound trajectory.Moreover, interestingly enough, researchers discovered that one species of dung beetles navigate by using million-time dimmer polarization patterns of moonlight. Dung beetles use it as an orientation guide to leave their food source in a straight line to avoid aggressive fights⁴. To find out how the beetles are able to use the polarized light of the moon to navigate, researchers observed the beetles under the night sky. On nights when the moon was visually clear, the beetles continued to forage and roll their dung balls in a straight line. On moonless or cloudy nights the beetles could not maintain a straight path.

Reflections from water

In nature, important reflections come from water where the polarization distinguishes between water and other reflective surfaces. Horizontally polarized UV light reflected from the surface of water is the main optical cue for habitat finding by insects living in, on, or near water. Weak UV light emitted by a horizontal surface below flying backswimmers can cause the animals to turn their flight paths vertically downward, bringing them to the horizontal surface⁶. Polarization sensitivity has, likewise, been demonstrated in crustaceans, like in the shore-living water flea Daphnia pulex. These animals were shown to swim toward polarized light, which in nature would lead them away from the shore towards deeper water⁷.

Human activity can have overwhelming effects on the natural environment and man-made objects, such as crude or waste oil surfaces, asphalt roads, glass surfaces, or plastic sheets used in agriculture are unfortunately more attractive to water-seeking polarotactic insects than the water surface itself. This effect can be very dangerous for polarotactic insects as these objects function as insect traps. Researchers have observed that every year, in May and June, swarms of mayflies mate, not above lakes and rivers, but above dry asphalt roads and lay their eggs in vain on dry asphalt roads or car-bodies. The horizontally polarized light from these surfaces mimics a highly polarized water surface.⁸ .

Ocean animals

For many ocean animals, sensing polarization may be even more important than sensing color. One possible use for polarization in the ocean (and elsewhere) is signaling: communicating with neighbors, rivals, and potential partners. Recent discoveries have shown that stomatopods (Mantis shrimps), a sort of shrimp found on reefs around the world, use special body areas to communicate with polarized light (Fig.6)⁹. Polarized light can also be used to ‘break the camouflage’ of aquatic organisms because, although from most viewing angles they match the color of the water behind them, the nature of the polarization is quite different. Researchers have found that transparency of aquatic organism to avoid detection can be broken with the help of polarization sensitivity¹⁰. In their experiment, they observed that squid detect zooplankton prey under partially linearly polarized lighting 70% greater than those achieved under non-polarized illumination.

In summary, polarization is central to most of the animals’ lives. It is abundant in the nature in various forms. Here, we have given only couple of examples of ways of various animals’ exploitation of polarized-light information. It seems, as researches continue, that the already long list of animals utilizing polarized light will get even longer as we learn more about it. Yet, even these mentioned examples above are enough to help us realize how perfectly these small animals have been created, and how well they are taken care of in their daily lives when they navigate, communicate, recognize a mate, lay eggs, detect water surfaces, or perhaps even break camouflage. Here, it seems necessary to observe that “The tiny body of a fly is connected with most of the elements and causes in the universe; indeed, it is a summary of them. If it is not attributed to the Pre-Eternal and All-Powerful One, it is necessary for those material causes to be themselves present in the immediate vicinity of the fly; rather, for them all to enter into its tiny body; and even for them to enter each of the cells of its eyes, which are minute samples of its body.” We refer the interested reader to Said Nursi’s reputable article of “A Treatise on Nature”¹³ and conclude with his aphorism: “He who created the eye of the mosquito is the one who created the sun.”

There was a peaceful silence and was pouring light upon light

Things were being done with the precision of clockwork;

Centuries-old confusions disappeared one after the other.

All were respectful to each other and behaved in sincerity;

Water of life was flowing through taps of porphyry.

Holy ones were as if on parade with faces bright with faith

As they walked, they gave strength to our hopes.

People were busy with founding a new world;

The earth was so luminous as if to compete with the sky.

When those heroes with penetrating sight passed by me,

I came to understand that mankind were in the time promised.

I saw young men with clear signs on their faces and concluded

They were those promised to come toward the end of time

I continued my way without stopping, nor becoming tired;

I met those who had absorbed light from the ‘grand fountain’.

Some, full of gratitude, were walking arm-in-arm;

Finally all reached their destination, which is the Pure Path.

He is the Lord of the heavens and of the earth, and all that lies between them; He is the Lord of the Lasts. (Saffat, 37.5)

The concept of the Lord of everything is defined in this setting and within the limits of our knowledge. Since the earth, the sky and all else in between have been mentioned, a different reality or a different spatial continuum is not in question. The verse does not end there, however. A new concept is added: ‘He is the Lord of the Lasts.’

So, in addition to the earth, the sky and all in between, we have the concept of ‘Easts’. In Arabic, the plural form is used for three or more things. Therefore, God is the Lord of at least three Fasts, or of many Easts. What kind of scientific concept does this verse introduce? Before seeking an answer to this question, let us call to mind certain facts.

It is a commonplace that we conceive of space in terms of three dimensions. The existence of an object is determined by the space it occupies with respect to the dimensions of length, width and height, in addition to its position.

But is the universe composed of, and space constituted by, these three dimensions alone? Until Einstein’s Special and General Theories of Relativity, scientists believed that the universe consisted of three dimensions. The world-famous physicist, however, determined on the basis of mathematical calculations that there are more than three dimensions and that a fourth, fifth or higher number of dimensions would introduce different concepts of space.

According to Einstein, the fourth dimension is time. Time is not simply a matter of reading a clock, but a dimension of the same order as height, width and length. It is coextensive with the other dimensions. Our visual perception, however, can see in only three dimensions and no more. In fact, some organisms cannot even see the dimension of depth: lizards and snakes see the world in two dimensions, like a photograph or a movie cartoon.

Starting from this milestone of physics, we would have to conceive of spaces other than ours, and in addition to the physical space we observe in the universe at large. In these spaces, velocity is different, time is different, action is different; and so are translation, convergence and regression. This is why the concept of ‘worlds’ introduced by the Qur’an is an expression of such diverse spaces. The world of angelic beings, Heaven, Hell, and the world of spirits all lie in the domain of such spatial continua. Our difficulty in conceiving of them stems from the perceptual deficiencies of our three-dimensional habits.

Having noted this, let us now recall the final part of the verse: ‘He is the Lord of the Easts.

‘East’ is the expression of a direction, a dimension. This expression occurred for the first time in connection with the sun. The word ‘orientation’ or finding one’s bearings implies the Orient or East as the first or primary dimension. Although the expression Lord of the Easts and of the Wests occurs in many verses in the Qur’an, only the Easts are mentioned in this verse. This is why we are dwelling on this point at such length.

The point is that ‘the Easts’ are proclaimed as a set of directions, quite apart from the existents we refer to as the earth and sky. With this verse, God draws our attention to other directions and dimensions, indicating the existence of worlds and spaces composed of dimensions other than the physical world we are familiar with. In a sense, He says I am the Lord of the Easts in order to introduce the notion of infinite dimensions, which contemporary physics is just beginning to discover. But why only the Easts? Because in the definition of dimensions, the first dimension is the East, whereas the West is simply an extension of the Eastern dimension in the opposite direction. We can say that this verse clearly heralds the existence of thousands of spaces and worlds embedded in an infinite-dimensional matrix.

Many other meanings derive from the verse besides the meaning discussed above. I would like to mention two of these.

The meaning ‘births’ can also be derived indirectly from the plural mashariq. In this case the meaning points to a different scientific truth. The East, which is where the sun rises, also symbolizes the direction in which the earth moves around the sun. But, do we have only one East, or only one motion in the universe?

No. While the earth revolves around the sun within the solar system, the sun is also revolving around the Milky Way galaxy together with its family of planets. The Milky Way, in turn, is revolving around the central axis of the supergalaxy or local cluster of galaxies to which we belong. Thus, we may well speak of three different Easts.

This meaning, therefore, is also hidden within the statement ‘Lord of the Easts’ (rabbul-mashariq). The very fact that magharib (Wests) does not succeed mashariq (Easts) in this verse is a confirmation of this. We shall see while interpreting future verses that there are many statements in the Qur’an pointing to the rotation of the earth. For this reason ‘East’ in reference to the earth’s revolution is in the plural, indicating that these rotations occur at many levels.

If we take the verse from the standpoint of a direction on earth, the concept of the East differs for each location on the globe. The east of Turkey is in the east with respect to its western regions, while our east is actually west from the standpoint of Iran, which lies even further east. Therefore, the East concept is different at every point on earth, and these concepts form an ensemble of Easts. This concept geometrically defines the surface of a sphere.

Let us now reread the verse in order to discover another significant scientific observation: He is the Lord of the heavens and of the earth, and all that lies between them; He is the Lord of the Easts (Saffat, 37.5).

The heavens, as we also see from other Qur’anic verses, are very diverse spheres. So what does the expression ‘between the heavens and the earth’ mean? It is known that meteors, stars, even angels and various unknown beings, can be encountered at various levels of the sky. What are ‘those between earth and the sky’? As far as we can tell, they are invisible rays which form the basic building blocks of matter and energy. These rays, earlier lumped together under the generic term ‘cosmic rays’, are differentiated in modern physics within the broad categories of nucleons, haryons, leptons and fermions. These are the subatomic constituents of matter and energy.

With the expression ‘He is the Lord of the heavens and of the earth, and all that lies between them’ God explains that all these energetic particles and rays constitute a vast physical order subject to God’s attribute of Lordship. Modern physics has viewed these incomprehensible energy dissipations and rays with unease, almost seeing them as dangers threatening the destruction of the universe. The Qur’anic verse reveals that, on the contrary, they form a gigantic physical balance under the superintendence of God.
