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)

“Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them: the starry heavens above me and the moral law within me.”
Immanuel Kant

Since the very beginning, humankind has been probing the universe and standing in awe as we learned more and more about it, thus increasing our curiosity even more. Each discovery has revealed how little we collectively knew and has helped to showcase the marvelous creation of the universe.

In December 2019, the Daniel K. Inouye Telescope (DKIST), the world’s largest solar telescope, started capturing the highest-resolution images of the Sun that were ever taken. The motion on the surface of the Sun was observed in detail, and the magnificent image of millions of solar flares, each much larger and more effective than any volcanic eruption on Earth, enthralled scientists.

With its myriad of features such as its location, size, energy, and structure, the Sun is an indispensable resource for Earth. This source of heat and light was most likely created approximately 4.6 billion years ago to set the Earth ready for all the living things that were going to come much later.

It is a known fact that the Sun has a major role among all causes on which all life on Earth is dependent on. In fact, this is exactly what makes the Sun unique, or else it is just one of the billions of stars in the Milky Way. For instance, there would be no plants since photosynthesis is triggered by energy from the Sun. Processes that are crucial to the maintenance of the environment, such as water circulation, i.e. evaporation of water from the seas and oceans and its downpour elsewhere would not be possible. Winds would also not occur as they are caused by differing temperatures in the atmosphere. Without the Sun as the apparent cause of many vital processes, seasons would not emerge in the world, nor would the formation of vitamin D in our bodies would be possible. Of course, all of these phenomena are within the frame of the laws of creation, and our Lord can also create without cause or reason.

Location and size

While the Sun is 26 thousand light years far from the center of the Milky Way, its distance from the planet Earth is about 150 million km, which equals 8 minutes and 31 seconds at the speed of light. In other words, we are unable to watch the Sun live but can witness how it looked 8 minutes ago.

The Sun, normally a white, medium-sized star, appears yellow due to the Earth’s atmosphere. It is comprised of 91% hydrogen, 8.9% helium, 0.1% carbon, and other elements such as nitrogen. It is one of the stars we otherwise see during a clear night sky.

While the Sun is enormous in comparison to the size of Earth, it is a relatively small celestial object when compared to the size of the Universe. Our solar system consists of eight planets, several moons, numerous asteroids, and the Sun. The Sun, the heaviest and largest celestial body in the system, is 600 times larger than the total volume of all of the system’s planets. Equaling 99.8% of the total weight of its system, the Sun definitely generates a huge gravitational force which causes the other celestial objects to orbit itself. There is a perfect balance between the gravitational force of the Sun and the centrifugal force of the planets. If the rotational speeds of the planets were slower, they would quickly be pulled towards the Sun and consumed.

The Sun is a huge ball of flame with the temperatures of 5-6 thousand degrees Celsius on its outermost shell and 15-16 million degrees Celsius at its core. Its surface is in perpetual motion due to the convective movements triggered by the heat from its core [1]. Due to consecutive explosions and stirs that result in a kind of “plasma soup,” there is no fixed temperature on the Sun. The concentration of the surface magnetic field in certain regions prevents a purely homogeneous heat distribution. This is how the “sunspots” – dark-colored areas on the Sun’s surface – are formed.

Movements of the Sun

“And the sun runs the course appointed for it for a term.” (The Qur’an, 36:38)

As stated in the Holy Qur’an, the Sun moves on an orbit. While the Sun rotates around itself, it also travels towards Vega, a star 25 light-years from the Earth, at a speed of 220 km per second. The Sun completes a tour of the galaxy in about 230 million years.

The Sun rotates around itself at an average of 70 thousand km. Since it is in plasma form, the Sun moves at different speeds in different regions. The equator region completes one cycle in 25 days, while one cycle of the pole regions takes 35 days. The interior of the Sun is extremely volatile: A French research group led by Prof. Laurent Gizon examined the seismic sound waves in the Sun and discovered that the core of the Sun rotates 3-4 times faster than its other regions [2].

Similar to that of the Earth, the Sun has magnetic north and south poles that are in perpetual motion. These poles shift places every 11 years.

Reactions in the Sun

It is estimated that the hydrogen fuel of the Sun, which is counted among the middle-aged stars, will end after 6.5 billion years and thus send it to an utter collapse within itself which will result in it becoming a small star called a “white dwarf.”

The central region of the Sun undergoes intense pressures due to gravitational force. These pressures cause nuclear fusions and the energy produced through radioactive reactions in the Sun reaches to the Earth as light and heat. Every second, 564 million tons of hydrogen turns into helium, while approximately 4.5 million tons of material turn into energy and radiates into space.

Simply put, there are 400 billion 1-megaton strong nuclear explosions happening at any moment in the Sun. Moreover, the energy the Sun produces in one second is 6.1 million times more than that of the atomic bomb dropped on Hiroshima. Only one in 2.2 billion of the energy the Sun emits in space reaches the Earth and ends up catering to the needs of living beings.

Mercy rather than disaster

Particles that escape from the corona layer of the Sun, which perpetually moves with nuclear explosions with a temperature of about 1 million degrees Celsius, are dispersed into space. This wind of charged particles is emitted from the Sun in every direction at a blazing speed of 400 meters per second. This magnetic breeze called “Solar Wind” impacts the magnetic field of the Earth and causes storms in the magnetosphere layer of the atmosphere.

Fortunately, our planet Earth is protected by a magnetic shield, which deflects these harmful rays from the Sun to the polar regions.

The magnificent view of the polar lights of blue, red and green colors called “aura” in both poles is caused by the collision of the magnetic field waves from the Sun with the Earth’s atmosphere. This wonderful natural light show mostly takes place at the poles because the north and the south poles are the zero points of the Earth’s magnetic attraction where charged particles intensely enter the atmosphere.

Unexplained force

Large enough to house 1 million and 300 thousand Earths in itself, the Sun works like a giant nuclear reactor in which radioactive events take place with such subtle calculations that scientists cannot yet fully explain. This is a miraculous phenomenon, for normally, it is not possible for four positively-charged hydrogen atoms – which normally move around randomly – to come together and form helium.

Fusion radioactive chain reactions in the Sun continue as follows:

a) ¹H + ¹H → ²H + β⁺ + V_e

b) ²H + ¹H → ³He + ϒ

c) ³He + ³He → ⁴He + ¹H + ¹H

First, while two hydrogen (¹H) particles join, “deuterium” (²H) – which has a proton and a neutron – as well as positron and energy are created. Thanks to another hydrogen reacting with deuterium, a helium isotope with a neutron and gamma rays are formed. The reaction of this helium with similar helium particles results in the formation of two-neutron helium and two hydrogen atoms.

The force that fuses the two separate atomic nuclei that hold deuterium together is called “strong nuclear force.” The nature of this force cannot be fully explained. Theoretically, it is said to be generated through the back-and-forth movement or effect of a particle called “pion” between the protons. This force is the greatest physical force in the universe and is 10³⁶ times stronger than the force of gravity. Thanks to its power, this force is capable of fusing two hydrogen nuclei that normally repel each other with great force.

If this force was weaker than its current level, it would not be able to hold two hydrogen nuclei together. Any two adjacent protons would repel each other immediately, and the nuclear reaction in the Sun would end before it started. That is, the Sun would never exist.

What if the strong nuclear force was a little bit stronger?

George Greenstein explains that if this great force was a bit stronger, then the Sun would change completely, for the first stage of the reaction in the Sun would then be the production of di-protons, not deuteron. The weak nuclear force would be reduced to null and only the strong nuclear force would remain in the loop. In that case, the Sun’s fuel would immediately become so disproportionately effective and massive that the Sun and all similar stars would be blown to smithereens in a matter of seconds [3].

Yet, this is not so. The Sun has been set into motion as the main source of life on Earth, located millions of kilometers away.

“The Sun and the Moon are by an exact calculation (of the All-Merciful).” (The Qur’an, 55:5)

NASA Mission Sheds New Light On the Sun

Bale SD et al. “Highly structured slow solar wind emerging from an equatorial coronal hole.”

Howard RA et al. “Near-Sun observations of an F-corona decrease and K-corona fine structure.”

Kasper JC et al. “Alfvénic velocity spikes and rotational flows in the near-Sun solar wind.”

McComas DJ et al. “Probing the energetic particle environment near the Sun.”

Nature, December 2019.

Although the sun sits at the center of our solar system, its most basic behaviors still remain a big mystery. NASA’s Parker Solar Probe, launched in 2018, aimed to address some of the fundamental questions about the sun: Why is the sun’s outer atmosphere, the corona, so hot? Where does solar wind come from, and what causes it to be shot out of the corona? What makes the sun flare up sometimes, shooting even more excited particles out into space? These are some of the questions that scientists hope Parker can answer before its mission ends in 2025. Meanwhile, Parker got very close to the Sun for several days last November and in April 2019. Parker Solar Probe during its two encounters traveled within 15 million miles of the Sun’s surface, far surpassing the 25-million-mile record first set by NASA’s Helios 2 mission in 1976. Parker has also claimed the title of the fastest human-made object in history from Helios 2, as it surfed near the Sun at over 153,000 miles per hour. Its first batch of released results came from measurements of the corona, which is, remarkably, hotter than the surface itself. The corona extends millions of miles from the surface into space. The region is only visible to the naked eye during a solar eclipse as a golden ring hanging in a darkened sky. The corona emits powerful streams of high-energy particles, known as solar wind, which can be felt all across the solar system. Parker’s data shows that solar winds are far more turbulent near the sun than in our own vicinity. The wind drags the sun’s magnetic field out into space, and even bends the field enough for magnetic forces to completely flip around for a few minutes at a time, pointing back at the sun itself instead of into space. The strength of this effect was completely surprising and puzzling. Scientists also found that shifts in the sun’s magnetic field speed up the particles flowing away from the sun much faster than any of their models had previously predicted.

This really highlights the idea that proximity is everything for studying the sun. Parker continues to edge closer to the sun. As its orbit shrinks, it will eventually reach a perihelion distance of just 6.16 million km in 2025, where it will experience temperatures of nearly 1400°C. Thanks to the protection provided by its specially-designed, carbon-composite heat shield, the probe won’t melt and the spacecraft and its instruments will be kept at a temperature of about 29°C.

Science Stands Behind Bilingual Children

Nicoladis et al. “How to use a wide variety of words in telling a story with a small vocabulary: cognitive predictors of lexical selection for simultaneous bilingual children.” Language, Cognition and Neuroscience, October 2019.

A new study shows that bilingual children use just as many words while telling a story in either language as do children who only speak one language. Past research showed that bilingual children score lower than monolingual children on traditional vocabulary tests. However, these new findings may change the understanding of multiple languages and cognition in children. Learning a word is directly related to how much time is spent in each language. For bilingual children, time is split between languages. As expected, they tend to have lower vocabularies in each of their languages. However, this new research shows that as a function of storytelling, bilingual children are equally strong as monolingual children. Researchers examined a group of French-English bilingual children who had been taught two languages since birth, rather than learning a second language later in life. They used a new, highly sensitive measure for examining cognitive flexibility, a participant’s ability to switch between games with different rules, while maintaining accuracy and reaction time. Their study builds on previous research examining vocabulary in bilingual children who have learned English as a second language. Overall, the bilingual children used just as many words to tell a story in English as monolingual children. The children also used just as many words in French as they did in English when telling a story. Their analysis suggests that the number of words that bilingual children use in their stories is strongly correlated with their high levels of cognitive flexibility—the ability to switch between thinking about different concepts. Researchers emphasize that parents of bilingual children do not need to be concerned about long-term school achievement. Vocabulary is a strong predictor of success in education, and so is storytelling. In a storytelling context, bilingual kids are able to use this flexibility to convey stories in creative ways.

New Tomatoes Engineered for Urban Gardens and Outer Space

Kwon CT et al. “Rapid customization of Solanaceae fruit crops for urban agriculture.” Nature Biotechnology, December 2019.

Humanity have a massive problem: feeding our future selves. As a result of rising population, continued destruction due to climate change, and the fact that sustainable land use is becoming ever-more challenging, learning how to grow enough food for everyone is a burning question to address in the agriculture field. In an effort to grow more crops in smaller and less-than-ideal locations, scientists developed new genetically-modified “urban” tomatoes that ripen in compact bunches similar to grapes. These tomatoes resemble a bouquet whose roses have been replaced by ripe cherry tomatoes. They also mature quickly, producing ripe fruit that’s ready for harvest in less than 40 days. Scientist utilized the CRISPR gene-editing technology and produced the new tomatoes by fine-tuning three genes that control the switch to reproductive growth and plant size: 1) the SELF-PRUNING (SP), 2) SP5G, and 3) SIER genes. While the first two genes have the duty prevent growth, flowering and fruiting of the plant sooner, the SIER gene is in charge of controlling the length of the plant’s stems. Altering the first two genes resulted in tomato plants that didn’t produce a lot of fruit and tasted poorly. It was not until the scientists identified the third gene that they were able to produce the desired plant. This study demonstrates that we can produce crops in new ways, without having to tear up our land as much or add excessive fertilizer that runs off into rivers and streams. This could also be a complementary approach to help feed people locally and with a reduced carbon footprint. Climate change is expected to change growing conditions on Earth, worsening conditions for many crops.

Farmers could soon be growing tomatoes bunched like grapes in a storage unit, in a shipping container, on the roof of a skyscraper, and – as humanity stretches out past low Earth orbit toward the moon – eventually, in Mars.

She stood at the edge of the abyss, the blinding darkness engulfing her, enticing her. It would be easy to let go, to wither away and join him. Her arms felt numb, and her powerful legs were weak. Violent tremors traveled up and down her body. A small compelling hand, wet with tears, tugged on her arm. “What will we do now?” a quavering voice whispered. She opened her eyes. The sky was a cerulean blue, and the blazing sun was beating on her torn straw hat, casting a slender shadow on the spring green rice fields. Her rapid heart was calmed by a wind that caressed her cheek. To her dead husband, to her children, to Vietnam, she dropped the condolence letter, and with her feet firmly planted on the ground, said, “We will live.”

To say it was easy is an understatement. Raising five kids as a single mother, in a country where women are expected to be docile, seemed infeasible. “I was taught at a young age that men were the head of the household, they were the heroes of the family,” Diep Ngo, aged 80, recalls sadly, her eyes distant. “I felt helpless. My brothers were charting new paths, while I was still, unable to move.” With a suppressed sob, Ngo recounts that at the twilight hour, she would drown with dark thoughts, but every morning when the sun rose, they would be vanquished. The roosters were the reveille that awakened her slumber, her empty stomach was the battle cry, and the last words of hope from her departed beloved, the mantra that carried her on. 

The war took its toll on the civilians of Vietnam; it was a disease that plagued families with deaths and injuries. Young girls were jailbirds, kept busy looking after their younger siblings, torn rags their striped attire and restrictions the bars of their prison. Dreams were locked away, replaced by the basic needs crucial to survival. Even so, when asked if she would take part in the war that claimed her husband, Ngo, her mouth in a straight line and her eyes ablaze, adamantly nodded. Raising both arms until her fists were level with her head, she mustered a grimace. Her nose crinkled and teeth bared, but her eyes sparkled with humor. “Do you think anyone would’ve thought twice about taking me on?”

Scraping bits and pieces of broken memories from her childhood, Ngo recalls that the only freedom she truly had was that from the pressures of education. “I never did well in school. Women were not expected to accomplish anything, so it was highly unusual for a women to achieve higher education.” Now, it seems clear that this supposed freedom transformed itself into another burden upon her shoulders, for she had to take on menial tasks when drafted into the position of “man.” For the first time in her life, she left the cage built by the patriarchal society and refused wealthy suitors. “They were bloated with pride… I would never submit to any man like that.” Ngo was ridiculed by her neighbors as a result, but she felt a strange sensation, absent from her life ever since the fateful, disappointed sigh that accompanied the doctor declaring her gender 80 years ago: the jewel of independence.

“As their father was gone, I had to step into the role of the provider. Oh, what a burden it was, but the power and purpose it gave me fueled the sleepless nights.”

Before the age of 30, her long, black hair turned a platinum gray, and impending wrinkles scarred her face as the war robbed her of youth. A moment to weep or reconcile with memories of loved ones was lost in the present.

“Losing my husband was truly hard, but myself, and other women of Vietnam, had to choke back grief and look to the future,” she remarked. Leaving the house militarily before the sun rose and coming back well after the crescent moon silently loomed in the sky, the only thing Ngo regrets is not spending as much time with her children. But, what she had to do was necessary, as every day was a battle. Even so, how could she explain to them the rough calluses on her hands, which toiled tirelessly, tending the infested wounds left after the hungry bullets pierced the heart of Vietnam? How could she explain yet another outline of a large palm on her red cheek, this time from an angry customer, unsatisfied by the knee-length trousers she had spent all night mending?

Through it all, she remained an eternal warrior, whose struggles rivaled those of men fighting raging wars. Diep Ngo battled gender inequality and injustice, all while leading her family through desperate times. An old poem by Xuân Diệu filled her thoughts as America, the land of rebirth and opportunities, slowly emerged on the horizon: “Your feet have hardly tread round this way… Open your arms to clasp the spring, then from your hand let there be light” (translated by Thomas D. Le). And for the first time since her husband’s death, she welcomed the moist tears, for the valiant soldier’s burden had been lifted. Her dauntless mission was complete. 

I’m forever grateful for her valiant decision to bypass social stereotypes and become a sort-of soldier, leading her family to survival, to new opportunities, to an education, to happiness, to America. It’s a natural, humane feeling that is respectful of the wisdom, the strength, and the sacrifices of the old. Every evening, after the tiring cycle of school, I retreat back into my place of comfort: my grandmother’s arms, and for the past 17 years, her past life was but a false, beautiful painting, rid of pain and hardships and suffering. That one night, under a blanket of softly twinkling stars, I retraced her hands, touching them, caressing them, tracing her old, calloused, scarred fingers and her bulging veins, to finally realize the truth: that there was so much I didn’t know about my hero.

Enveloping our body like a piece of clothing, our skin is a miraculous organ that both forms a barrier against potential invaders and plays a crucial role in the maintenance of vital functions. It is a mirror that reflects our experiences, memories, and fate with the lines and marks on it. With a surface area of 1.72 square meters and a weight of approximately 9.6 kg, including the fatty tissue under it, the skin is the largest organ in our body and life cannot possibly be maintained without it.[1] It is through the skin that we learn knives cut, fire burns, and our mother has very soft hands. We don’t even realize, but the skin quietly carries out other numerous functions such as sweating toxins out of the body, maintaining body temperature, and synthesizing vitamin D.[2] Some of these functions are related to the sun and the protection of our body from it.

The sun emits all kinds of rays across the electromagnetic spectrum. The lethal ones among these rays are filtered by the atmosphere that envelops the Earth, so very few of these dangerous rays reach the land.[3] The rays that reach Earth are visible (wavelengths of 400-700 nm) and ultraviolet (wavelengths of 100-400 nm) rays. Ultraviolet radiation comes in three types: UVA, UVB, and UVC.

Having wavelengths of 320-400 nm, UVA rays make up 90% of the UV that reaches Earth’s surface. Regardless of whether it is cloudy or sunny, the same amount of these rays reaches Earth and penetrates as far as the lower layers of the human skin. UVA rays damage the connective tissue under the skin, causing the skin to get old and the formation of free radicals, which indirectly cause DNA damage, hence terminal skin cancers or melanoma. Rays that come in these wavelengths are also largely responsible for allergic reactions on the skin.

With wavelengths of 280-320 nm, UVB rays make up 5-10% of the UV radiation reaching Earth. These rays help with the synthesis of vitamin D but also cause sunburns and the synthesis of melanin in the skin. UVB rays also have a role in mutating genes that prevent growth of tumors, thus leading to the development of skin cancers other than melanoma.

With wavelengths of 100-280 nm, UVC rays are harmful to living things. When they reach the Earth’s atmosphere, UVC rays interact with the oxygen atoms here. This interaction leads to the formation of the ozone layer, which prevents UVC rays from almost never reaching the ground. These dangerous waves have been put into humankind’s service by being employed in the creation of the protective ozone layer.

Ultraviolet rays and the harmful effects of visible light on the skin

There are short-term and long-term effects of UV rays on the skin.

The short-term effects are sunburn, heat stroke, allergic reactions, suntan, and viral diseases such as herpes, which are usually felt shortly after exposure to the sun and can be triggered by suppression of the immune system. The long-term, accumulative effects are photo-aging (the skin getting wrinkly due to solar rays), sunspots, cataracts, and the development of skin cancers.[4]

On the other hand, our skin is not entirely unprotected against the dangerous effects of the sun. The keratin layer in the epidermis, the uppermost layer of the skin, absorbs or disperses light, so the amount of light penetrating into the layers below is significantly lowered. Beta-carotene in the skin along with some enzyme systems reduce free oxygen radicals released after exposure to the sun and thus eliminate solar damage. Likewise, melanin, which gives our skin its color, lies above the nuclei in skin cells and acts as an umbrella that protects the cellular DNA from solar radiation.[5]

Six subgroups of skin types have been determined according to color of the hair, eyes, and skin, as well as the skin’s reaction to solar rays. This classification is widely accepted for identifying risk groups and determining specific protection measures.[6]

Although the number of melanosomes, or melanin-producing cells in the human skin, is the same in all humans, the color of the skin is determined by the genetic differences in the type, amount, and size of melanin pigments. Melonosomes in Europeans are small and light, while those of Africans are larger and darker.[7]

The importance of protection from the sun

The frequency of skin cancer has been increasing, which is precipitated by the fact that the ozone layer has gotten thinner and people are not well informed about UV protection. Many people take beach vacations and sunbathe, do mountain sports, have tanned skin, work in open air professions (such as construction workers, lifeguards, and tour guides), and they do so without much care.

For protection, we should first know that harmful effects of solar rays accumulate over time. The damage caused by the sun is stored in the body, just like change we save in a piggy bank. Unfortunately, we accumulate 40-50% of the total damage we are exposed to in a lifetime in the first quarter of life – that is, during childhood and our teenage years.[8] The skin’s natural protection mechanisms are not fully developed during these periods, nor is our understanding of protection. A research study carried out in Australia has shown that the rate of malign melanoma seen in young people can be reduced by 73% through effective solar protection methods.[9]

The major reason for wrinkles, the primary and fundamental indication of aging skin, is not in fact our age but the sun. UVA and UVB rays break down the connective tissue below the skin, disrupt the skin’s repair mechanisms, and cause skin aging (or photo-aging). Therefore, photo-aging takes place faster and earlier in people who work outside.[10]

{Picture: Photo-aging visible on one side of a truck driver’s face}[11] 

It’s imperative that we begin teaching children and adolescents about UV protection: having suffered five sunburns in childhood and early youth increases the risk of developing melanoma by 80%.[12] Children shouldn’t spend long hours in the midday, summer sun. 

Solar damage isn’t just more likely in children and teenagers, but also in people with skin type 1 or 2 (light skin), red hair, and/or colored eyes (blue); people, especially light-skinned people, with many skin moles; people whose family members have or had skin cancer; those who have a skin disorder triggered by the sun (lupus, dermatomyositis, rosacea); and people who have innate light sensitivity (albino, xeroderma pigmentosum, etc.). All these groups must be particularly careful about protecting themselves from the sun.

What are some ways to protect ourselves from UV Rays? Well, because UV radiation bombards the Earth most intensely at noon during the summer, staying indoors is greatly recommended between the hours of 10:00 am and 4:00 pm.  Additionally, the reflection rate of solar rays is higher by the seaside and in snowy environments.[13]

Wearing appropriate clothes is still the most effective and the least expensive method of sun protection. Clothing can have a solar protection factor (SPF) of 15-30. The level of protection is determined by the type of fabric, number of pores, and type, color, and thickness of weaving. The best clothes are made from cotton, silk, and denim and are unbleached and woven tightly. Wet clothes are more permeable. The use of wide hats, sunglasses, and umbrellas are also important for protection.

In addition to these measures, sun protection creams should also be used. The idea that protection creams will prevent the synthesis of vitamin D, voiced frequently lately, should not prevent the use of sun protection because the solar rays we receive during the day from the face and hands are sufficient for the synthesis of vitamin D. A person should pick a sun cream appropriate for their skin and apply it in sufficient amounts 20 minutes before going out. Babies should be protected through natural means, and physical sun protection should be used for children and pregnant women. A person should reapply sun protection products every two or three hours while outside, and, if planning to swim, they should choose water resistant products.

Besides physical protection that blocks, scatters, or reflects solar rays, there are also skin-absorbable chemical protections with cosmetically accepted formulations that eliminate light by absorbing it.

Generally speaking, a good sun protection should protect against both UVA and UVB rays. It should be cosmetically acceptable, non-toxic, water and perspiration resistant, and at the appropriate SPF (sun protection factor) level. However, because reapplication is required every two to three hours, protection above SPF 50 is the same. Therefore, it is no use buying a more expensive, higher protection product.[14] For people with type 3 skin (darker white skin with gold tone), SPF 30 is sufficient. For light skinned people, children, and pregnant women, however, SPF 50 is recommended.

SPF is the number indicating by how many more times a sunscreen protects the skin against UVB than the skin itself. Skin type is very important in sunscreen choice. The natural protection period of a person with type 1 skin is 5-10 minutes, while it may go up to 90 minutes for a person with type 6 skin. In other words, a light-skinned person gets a sunburn in 5-10 minutes of exposure, while a dark-skinned person may not get one at all. Therefore, these people should not choose products at the same SPF level. For example, if the skin’s self-protection duration is five minutes, a sunscreen with a SPF of 30 provides the same protection for 150 minutes.

Apart from sun protection creams, oral products can also help with sun protection. For example, oral zinc intake is proven to prevent cellular and DNA damage caused by UV radiation. Vitamin C is effective at preventing UVA rays due to its antioxidant properties and vitamin E at preventing UVB rays. In addition, the intake of beta carotene (a precursor of vitamin A) and bioflavonoids (also called vitamin P which generally has effects similar to vitamin C), found in orange and red fruit, protects against UV damage. Polyphenolic compounds in green tea also display protective properties against UV radiation.[15]

Finally, we should remember that using a sun protection product is a small part of our attitude toward your overall protection from the sun. Considering the role of the ozone layer in filtering the sun’s harmful rays, we should protect the perfect balance in the universe and re-evaluate our responsibilities and future actions for the maintenance of this balance.

“It is He who created the night and the day, and the sun and the moon; all (the celestial bodies) swim along, each in its orbit with its own motion.”  (Quran 21:33)

Almost everyone – depending on his or her age, experience, and education level – is aware of certain facts about nature. We know that the Sun rises in the east and sets in the west; water boils at 100 centigrade; humans have five basic senses; birds can find their way back after migrating thousands of miles; and many more. Likewise, laws of thermodynamics, laws of motion, universal law of gravitation, and laws of planetary motion are among the many tools scientists use to explain how nature and the universe work. In the same context, whether or not we are conscious of it, there is this ubiquitous fact of “revolving, rotating, and circling” in the universe in relation to science, religion, and culture. From the Milky Way, sun, planets, and moons to human eyes, circling is everywhere in the universe. Also, it’s imprinted everywhere in the natural world. Giving examples from scientific, spiritual, and social life, this article aims to inquire the “revolving, rotating, and circling” phenomenon to see if it has any implications for humanity.

Rotation of planets

Earth is one of the eight planets in our solar system, all of which orbit the sun, a giant burning star. We know from astronomy that the sun can fit more than one million Earths inside it. Throughout human history, stargazers have realized that all these planets move in a systematic way. The planets orbit due to the immense gravitational pull generated by the sun. Even though the rate may change, each planet rotates around the sun and on its own axis, an imaginary line running through the center of every planet. Also, there are more than one hundred terrestrial, gas, and dwarf moons that revolve around the planets. Every planet, except Mercury and Venus has at least one moon. For example, the Earth has only one Moon (Luna) which orbits around Earth every 29 days; on the other hand, Jupiter has at least 67 moons such as Ganymede, Callisto, and Europa in orbit around it. In addition, our solar system is swarming with different types of bodies (e.g. comets, meteors, asteroids, and space dust) that rotate around the sun along with Earth. Furthermore, it is believed that the Sun is one of about 200 billion stars (maybe more) just in our galaxy, the Milky Way. Galaxies move and gravitationally pull each other, and they do so while rotating around a center. That is, nothing is truly at rest. (1)

Orbiting an atom

In the 1920s, scientists of quantum mechanics discovered that an atom acts like a small solar system. While planets circle elliptically around the sun, electrons rotate around the atom’s nucleus in diffuse, cloud-like waves; these are known as orbitals since they tell us only the probability of detecting the electron at various places within the atom (Choe 2004). These orbitals can blend together to constitute a clump-like “wave packet” that includes the electrons and does rotate around the nucleus. It looks like this quantum phenomenon seems to support rotation in the universe. (2)

The circulation of blood

Doubtless, the heart is one of the most vital and fascinating organs in the human body. It incessantly pumps fresh blood with necessary nutrients throughout the body so that we can survive. Even though it is as big as your fist, it works like a powerhouse by expanding and contracting 100,000 times each day, pumping approximately five quarts of blood per minute, around 2,000 gallons every day. While the heart beats, it pumps blood through blood vessels in the circulatory system to every area of the human body, which takes about 20 seconds to circulate all over the vascular system. It is reported that the blood travels approximately 12,000 miles per day – nearly half the distance of the Equator (24,902 miles). Blood circulation is vital and fundamental to human life: it not only transfers fresh oxygen and nutrients to organs, but also carries away waste such as carbon dioxide from the organs, which is necessary to maintain a healthy life. (3, 4)

Five stages in the human life cycle

Similar to the cycle of four seasons (spring, summer, fall, and winter) in a year, the human life cycle has five or six different stages (Birth, infancy, childhood, adolescence, and adulthood). Human life begins as a single tiny cell, not bigger than a mustard seed, in a mother’s womb. After nine months, circa 40 weeks of pregnancy, the mother gives birth to a newborn. During the first year of infancy, the baby is entirely dependent on the parents’ care, but babies develop very quickly to independency. Childhood includes a period from age 4 to 13, when children learn to eat with utensils, dress and undress without assistance, make friends, play with other kids, and other things. Adolescence is the when a child develops into an adult, when teenagers undergo a rapid transformation of their bodies known as puberty. After the age 20, the human body reaches peak fitness and fertility by stopping development and growth. As we age in adulthood, it takes our body a longer time to repair itself and we become less efficient in many skills. (5)

Circling and prayer

It looks like that this one important pillar of Islam reminds us of the spinning motion in the universe, atoms, the circulatory system, and the life cycle. According to Islamic scholars, millions of pilgrims circulating the Holy Ka’ba in Mecca represents the deep reverence in Oneness of Almighty God. It is believed that these seven compulsory circumambulations of the Ka’ba (the most sacred site in Islam) include individual and social meanings like solidarity and maintaining unity. One explanation as to why Muslims circle the Holy Ka’ba seven times, is the Qur’anic verse that describes the sky above as of seven layers:

“The seven heavens and the earth and whatever is in them exalt Him. And there is not a thing except that it exalts [God] by His praise, but you do not understand their [way of] exalting. Indeed, He is ever Forbearing and Forgiving” (Al-Isra17:44).

It is known in Islam that the spiritual part of the human being includes seven different souls known as nafs. Therefore, every circumambulation of the Holy Ka’ba is meant to move from one spiritual level to the next in order to reach and complete the final expectation to turn our self (nafs) from meat and bone into a more delicate, sensitive, and loving form of soul, one even superior to the Angels. This act of circling the House of God, the Holy Ka’ba, shows how man is sincerely, spiritually, and lovingly attached to the divine.

Conclusion

The planets circle the sun, electrons circle the nucleus in an atom, blood circles the human body, pilgrims circumambulate Holy Ka’ba, and seasons and life cycles circle. There are many more examples of circling in the universe. Even though we cannot see all of them with the naked eye, the entire cosmos, ranging from invisible particles to the moons, planets, stars, and galaxies, are in rotation. Remember that all these rotations happen in accordance with the laws that govern the nature. There is no free choice in any of it.

People are members of this infinite universe, and, unlike planets, electrons, flowers, and cells, they can reason and decide, since we are blessed with free will. As Muslims circumambulate the House of God, this pulling motion between the Ka’ba and pilgrims escalates divine love by changing spiritual dimensions in a way similar to moths flying and circling a light source. Without doubt, a visit to the House of God is an obligatory and praised pillar of Islam, but I believe that the Merciful God wants us also to circle many other divine values and social qualities to deserve His love, mercy, and grace. As long as we circumambulate these highly valued vital qualities such as prayer, selflessness, charity, affection, forgiveness, respect, love, truth, compassion, modesty, patience, and all other good qualities, they will pull us closer both to each other and to Almighty God. Ignoring circling these divine and social qualities would be as if Earth left its orbit.

Gravitational waves can be defined as the vibration of space-time. Sky is an ocean in which the waves are stationary.

When you throw a rock into the water, when a taut rope is plucked, when a spring is compressed and then released, or when our larynx vibrates, what forms is a wave. In each case, the medium where the wave forms is different: water, air, etc. Interestingly, light waves do not need a medium to travel.  A common feature of all kinds of waves is that they have wavelengths, frequencies and amplitudes. Another important feature they have is that there needs to be a source that triggers the wave. A spring, for example, needs to be compressed to produce the wave.

Gravitational waves, on the other hand, can be defined as the vibration of space-time. These waves were predicted by Einstein in 1916 in relation to the general theory of relativity. Let us consider that all interstellar and intergalactic space is filled up with a substance similar to water. Then when, say, two black holes collide, space itself ripples like water. In fact, discussions have long continued over the existence of ether, a substance that forms the texture and essence of matter. If there are waves in space, then it is highly likely that there is ether that fills up space as well.

In a very interesting narration, the Prophet Muhammad, peace be upon him, is reported to have suggested that heavens are not a vacuum: “The sky is a wave held back” (Tirmidhi, Tafsir surah, 57/1). Bediuzzaman Said Nursi, in his interpretation of this hadith, says, “[Sky] is an ocean in which the waves are stationary” (The Gleams, Twelfth Gleam); in other words, heavens are a sea whose waves have settled, calmed and become still. The Qur’anic verse 36:40 reads “It is not for the sun to overtake the moon, nor does the night outstrip the day. All (the celestial bodies and systems) float (swim) in an orbit (determined for each).” We can infer from this verse that space is likened to a sea because floating or swimming can occur in a substance but not in a vacuum.

The discovery of gravitational waves

Gravitational waves were discovered by a team of experimental physicists on February 11, 2016, that is, exactly one hundred years after they were predicted by Einstein in 1916, and the discovery earned three physicists, Rainer Weiss, Barry C. Barish, Kip S. Thorne, the Nobel Prize in 2017. The LIGO observatory (www.ligo.caltech.edu/page/what-are-gw) used an extremely sensitive interferometer to detect the gravitational waves produced by the collision of two black holes, one having 29 times the mass of the sun and the other 36, 1.3 billion years ago. The researchers used such a precise mechanism that it (the interferometer) could measure the distance to the nearest star to an accuracy smaller than the width of a human hair.

The LIGO observatory used an extremely sensitive interferometer to detect the gravitational waves produced by the collision of two black holes, one having 29 times the mass of the sun and the other 36, 1.3 billion years ago.

The working principle of an interferometer is based on the idea of splitting a laser beam from a single source into two components and then recombining them. The split beams get to the target at the same time after diverging at a right angle and being reflected back from two mirrors. Scientifically speaking, there is not any phase difference between the two. However, if the beams are subject to an effect like gravitational waves, the waves cannot get to the target at the same time, or in scientific terms, an interference pattern is formed on the screen because of the phase difference. In the same way, the waves generated by the collision of two black holes had an impact on the movements of the perpendicular laser beams as they ran past the area that housed the interferometer built by the LIGO team and caused a time difference in their arrival at the detector. In this experiment, the effect of the gravitational waves was measured by directing laser lights through L-shaped vacuum tunnels four kilometers long. The length of the tunnels was so precisely adjusted as to measure a difference, if any, as small as a proton.

The reason why the laser interferometer was so finely tuned is that the waves generated by two colliding black holes are so infinitesimally weak that only such an experimental mechanism could capture them. In other words, the experiment had to be precise beyond the atomic scale because the gravitational waves that reached the solar system could change the distance between the sun and the earth by just the size of an atom. To reiterate, the mechanism was designed so precisely that it can detect differences between laser beams as short as ten-thousandths the size of a proton. It should be remembered that a proton is a very, very small particle in the nucleus of an atom with a diameter of 10^-15 (one-million millionth) of a millimeter.

Furthermore, the gravitational waves were discovered simultaneously by two separate interferometers, which were located at a distance of 3220 km from each other. The reason for the dual measurement tools was to ensure that the waves were indeed gravitational waves.

What has excited scientists most about the discovery of gravitational waves, besides their confirmation of Einstein’s theory, is the fact that we will be able to exploit gravitational waves in addition to light and radio waves in order to explore space. It can be foreseen that telescopes working with gravitational waves can be developed or advanced laser interferometers can be built in space and discover other gravitational waves.

Gravitational waves are generated in space all the time. Large-scale phenomena such as the collision of two black holes or the explosion of supernovae cause ripples in the sea of space. It is highly likely that systems that can detect these waves will provide us with new information about the fabric of space and thus lead to new discoveries.

The fact that gravitational waves were discovered using technological tools is an excellent example of how technology can nurture science. Moreover, this study proves that some discoveries can only be made by big teams like those in the CERN experiments.

It is postulated that the universe rippled violently during the first creation as a result of the tremendous expansion, the effects of which might still exist and should warrant new studies. It is only a matter of time that a super-sensitive mechanism could confirm the Big Bang theory. It is believed that the gravitational waves generated at the very beginning of this expansion are still present and experimental designs such as that in the LIGO are likely to discover them. The Qur’anic verse 51: 47 is considered to be referring to this expansion: “And the heaven, We have constructed it mightily; and it is surely We Who have vast power, and keep expanding it.”

It is almost certain that technological progress will lead to new discoveries that will provide us with deeper insights into the incredible composition of the universe. Bediuzzaman describes the universe as “a rosebud, wrapped in thousands a variety of veils of unity” (The Rays, Second Ray, Third Station). Every new discovery is going to show us the magnificent secrets of this rosebud.

In order to find answers to these questions, let’s consider ourselves sitting at home after a long, tiring day. Are we aware that we are moving very fast even at a moment when we seem to be resting? When we travel by bus, we are motionless from the standpoint of a sitting passenger, yet have a velocity compared to an outsider standing on the sidewalk. The trees lining the road seem to be going backwards, but they are fixed to the ground with no speed. Therefore, velocity is relative and we in fact move at different speeds while sitting at home depending on the objects of reference. We have a zero velocity relative to our guests sitting with us on the couch, but have various speeds compared to the center of Earth, the moon, the sun and the center of the Milky Way galaxy. Not only us, but all existence in the universe has a movement, or oscillation. This movement is usually in the form of a revolution for objects of important mass and as a vibration for particles with smaller masses.

The shining celestial bodies of the cosmos rotate around themselves like whirling dervishes. They revolve around other heavenly bodies or around their common center of gravities, such as pilgrims revolving around Ka’ba in Mecca. The gravitational force set in the universe pulls all objects towards each other. This gravitational force indeed pulls all masses together; however, it is counterbalanced by the motion of revolution given to grand heavenly bodies. As a matter of fact, everything is moving: a solar system with its planets, moons, and comets; the Milky Way galaxy, along with billions of stars, nebulas, galaxies, interstellar dust, gas clouds, and other celestial objects… all are moving in a giant rotating motion like a carousel. In this article, you are going to find some of the scientific findings of our revolving planet, the sun, and the universe, and how some verses in the Qur’an sound miraculously relevant to them.

The Earth’s motion

First of all, we have a velocity stemming from the Earth’s rotation. People living on the equator travel approximately a thousand miles per hour in reference to the center of the globe due to this rotation. While people on the poles never gain any distance over 24 hours, people on the equator travel nearly 23,800 miles! Inside a plane, because we move at the same rate as the plane, we cannot feel its speed. In a similar way, since we move at the same rate as Earth, we cannot feel the globe’s movement.

There are many benefits associated with the Earth’s rotation. The delineation of day and night, atmospheric jet streams, oceanic currents, and similar events rise from the rotation of Earth around its axis. For instance, it causes the warm water currents of the Gulf Stream to reach England, generating a warm and rainy climate.

There are verses in the Qur’an that point to the globular shape of the Earth and its rotation around its axis and revolution around the sun:

“He has created the heavens and the Earth with truth. He wraps the night around the day, and He wraps the day around the night. And He has made the sun and the moon subservient (to His command), each running its course for a term appointed (by Him). Be aware! He is the All-Glorious with irresistible might, the All-Forgiving.” (Az-Zumar 5)

Yet another verse furthers this point:

“It is He Who has created the night and the day and the sun and the moon. Every one (of such celestial bodies) floats in its orbit.” (Al-Anbiya 33)

The verb “wrap” is usually used for round objects, and the perpetual arrival of day and night are only possible with a circular planet. The Earth’s rotation leads to different days, on the micro level, and different seasons, on the macro level. The Qur’an concisely summarizes all these physical events with the simple phrase, “wrap the night around the day.”

The Earth’s primary motion is around the sun. We are roughly 93 million miles away from the sun and we make this orbit, which is nearly 584 million miles, every 365 days. According to the center of the sun, our average velocity on this orbit is approximately 66 thousand miles per hour.
In addition, other planets travel around the sun via different orbits and speeds, each moving on a separate plane. For a moment, it is significant to visualize the sun, which is more than a million times larger than Earth, with its planets and other viscera revolving around it via no visible bond between them.

The movement of the sun

As stated earlier, when we travel on a bus, we observe the trees and buildings near the road going backwards even though we are the ones moving. In a similar way, we see the sun as revolving around us, though in fact the Earth is the one moving. In the Qur’an, the chapter of Al-Anbiya, the verse reading, “each running its course,” is about the creation of the sun and moon, clearly pointing to their movements. Unfortunately, the verse that reads, “A(nother) clear sign for them; And the sun runs the course appointed for it for a term to its resting-place, for the stability of it(s system)…” (Ya Sin 38) was misunderstood as the sun revolving around the Earth. However, we know today that our sun is one of a couple hundred billion stars in the Milky Way galaxy. As such, it both rotates around itself and revolves around the center of the Milky Way galaxy, and confirms the miraculous declaration of the truth in the verse.

In addition, the sun also has a secondary movement inside the local star cluster towards a certain direction. We can explain this with an example: the atmosphere is in motion along with the Earth. Each particle and particle set that makes up the atmosphere not only moves right and left, but also has a total revolution around the Earth. The sun behaves in a similar way within the star cluster and around the center of the Milky Way.

How are we going to define the velocity of the sun? We can determine the sun’s speed by referencing a constant point depending on the average velocity of stars in the section of the galaxy that we inhabit. The sun, according to a local constant point, travels towards the shiny Vega star in the Lyra constellation with an average speed of 43 thousand miles per hour.

Apart from their individual movements, the stars in our galaxy also revolve around the galactic center. The velocity of this movement depends on the star’s mass and its distance to the galaxy’s center. The sun completes one loop inside the Milky Way galaxy every 225 million years. It has completed a total of 20 tours around the galaxy’s center since the Earth’s creation. Our Earth, which moves along with the Sun, travels around the galaxy’s center at nearly 492 thousand miles per hour.

The motion of the Milky Way galaxy

Our galaxy is one of the billions of galaxies in known space. Galaxies are the biggest known structures. The universe expands and galaxies move away from each other, conforming to the meaning of the verse, “And the heaven, We have constructed it mightily; and it is surely We Who have vast power, and keep expanding it” (Adh-Dhariyat 47). Our galaxy, along with nearby galaxies, is pulled towards the Leo and Virgo constellations. The cause of this attraction is not understood yet.

Since all galaxies are moving, how can we determine the velocity of the Milky Way galaxy? As is known, the entire universe is filled with cosmic radiation as a remnant of the Big Bang. When this radiation is taken as a reference, the Milky Way travels at around 1.3 million miles per hour.

At the moment, when we think we are sitting in place, we are actually moving around the center of the Earth, sun, our local star cluster, the center of the Milky Way galaxy, and also moving away from other galaxies. We have velocity in relation to all of these movements. The revolution of the universe is also a fact verified by the Divine word: “I swear by the heaven ever-revolving” (At-Tariq 11).

Love is the bond between all things – the light and life of existence. We love ourselves, our families, the place we live, our nation, living things, the world, and the whole universe. We feel pleasure when people we love are happy, and we feel pain at their pain. Sometimes it is hard to see something as so valuable or wonderful, particularly when there is plenty of it to go around or when it happens all the time. We forget that every healthy baby born is a miracle. We are surprised by one that has seven toes, not the ones who are perfect. How many of us are grateful every time we swallow something, take a breath, sleep or even go to the bathroom? If somebody loses sleep, or loses a kidney, then they know how good it was when they had it. Maybe sometimes we should think in the negative to see how it is right now.

For instance, let’s assume there wasn’t love in the world. Just think: nobody loved their spouses, their kids, their jobs, their country, employees, students, or friends. The trees feed themselves with muddy water, but feed their kids (fruit) with sugar, milk, and honey. What if they didn’t? What if they just became selfish? What if God didn’t love us? Didn’t listen to our prayers, and punished us with every little mistake we made? Would the sun still come up and smile at us in the morning? Would rain fall to give life to soil? Maybe not… The sun loves the plants, the plants love the sun. Animals like plants, and we love all of them. Love connects everything and everybody together. It forms families, turns a job or a class into fun, and makes labor pains bearable. It makes this big, scary, dark world, a home.

Whose faults do you see more clearly – those you love or those you don’t love? Doesn’t love hide all flaws and even turn flaws into something you might love later?

If I had to make a recipe for love, I would add more compassion than passion. Lots of relationships start with passionate love, but they will last longer when there is compassion. Love is not always looking at each other; sometimes it is simply looking in the same direction.

Our nature consists of a body and a soul. The body is to the soul what a purse is to the gold it holds. It is the spirit that matters, not the body. When the soul leaves the body, they do not let it stay at home. They bury it quickly. Our bodies are like a torch. Our reason, knowledge, and love are the light coming out of it. They light up our way. Remember that the two containers in us, the mind and the heart, never fill up. The more you learn, the more you can learn; the more you love, the more you can love. Our souls can also be compared to a pool. Our behaviors, habits, our five senses, and what we see, hear, and feel with them are like taps filling it up. What is in the pool depends on what flows from the taps. What do you want to fill it with? Love, hate, gossip, prayer, nice words, apps? You pick…

Love is the greatest motivator of all time. The wind and the sun argue about who is the strongest. The wind points to a guy on the street and says it will make the man lose his jacket. However, the mightier it blows, the harder the guy holds on to his jacket. When the sun shows its face, he takes it off willingly. Love and fear are two very strong feelings. You can make your kids eat healthy and you can make your students study; you can make your employees work hard and, in general, you can make people do things by intimidating them with harsh words, but this motivation is temporary. When you are not looking, they will go back to their old ways. But if it is in their heart, if they love it, you don’t have to be watching them all the time.

It is impossible to for me to not remember Rumi, the heart of the circle of guidance of his time, when thinking about love. People from all religions were drawn to him like spiritual butterflies drawn to light. He has been titled, “The Sultan of Lovers.” His is divine love, a fiery one with constant longing. During separation, he burns with fire. He shows no discontent though, because of the requirement for passion. Refraining from complaint is a sign of loyalty towards the beloved. For him, death is like a festival; it is a means for unity with the loved one. Rumi unifies the love of God with the love of humanity. He came to the conclusion that to love humans is to love God. A Turkish saying – we love all creation for we love the Creator – works in parallel with this.

Even if I don’t know what to say about love, I hope I can at least feel it and spread it. I hope all of us have lives filled with infinite love. Love that will make us love more, that will help us to be better people, and to really feel that we are alive. As Rumi says, “Every mortal will taste death, but only some will taste life.”
