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)

The world may not have ended on December 21, 2012, but that does not mean it won’t end at all. So what will be the force that will disperse this robust system of ours, rendering all forces including gravity obsolete, and forcing the sun and planets out of their orbits?

The universe contains billions of heavenly systems that travel interdependently in a perfect and harmonious fashion. What could be the obvious cause or force that could disrupt this great arrangement, deorbit the stars and planets, and make every other force ineffective including gravity? If we ponder upon the verses of the Holy Qur’an, “When the sun is folded up (and darkened). And when the stars fall (losing their luster)” (At-Takwir, 81:1−2), “And when the heaven is torn away (with all the truths becoming manifest)” (At-Takwir, 81:11) with our current cosmological advances, will Black holes be the cause that will likely destroy the Sun and even devour the light of stars so that they are unable to function?

Black holes are considered to have the potential to cause a universal apocalypse. It seems plausible that with such gravitational power of Black holes, mountains would be casted away, and magma displacement via volcanic eruptions could lead to major earthquakes. There are a couple of recent geologic studies pointing out the possibility that the gravity of the sun and moon play a role in development of earthquakes. The 7-8 meter rise in seas and 35-40 cm rise in land caused by lunar and solar eclipses are considered to be a possible factor among many factors that triggers an earthquake. Earthquakes of 12-15 Richter scale magnitude can occur because of the gravitational force of Black holes. The biggest earthquake ever recorded was of 9.2 magnitude; such that if it happens again, it can lead to a major catastrophe in a very short time.

Let’s not forget that we are residing on a globe filled with fire in its center. Gases that make up the atmosphere are held only with help of planetary gravity. One of the forces that will boil all the waters away and let all the gases escape the planet could be Black hole gravitation. The air in our atmosphere and resulting “air pressure” can be destroyed by Black hole gravity. Oceans would start boiling violently and then might evaporate off the planet. In this case, living things would suffer severe structural damages since all life forms are composed mostly of water (~70%). That is why astronauts wear a special space suit filled with air made up of normal atmospheric pressure when they leave the atmosphere. We should also keep in mind that trillions of heavenly bodies (asteroids, meteors, and comets) located in the two asteroid belts (Orion and Kuiper) may be freed from their gravitational control by the vacuum impact of the Black hole, causing colossal cosmic collisions.

The disruption of gravitational balance

There is a sensitive relationship between the elements of the universe, such as electromagnetic, nuclear forces and an apocalypse may result from a disruption of these.

According to the general relativity theory, the time-space plane can be rolled or wrinkled up like a paper. The gravitational force of black holes can cause the displacement of stars which are interconnected through weak web of attractions. As if a piece of net takes a specific shape when loaded with heavy objects, the web of space-time, also known as the cosmos, could be distorted and even torn apart by black holes with their infinite mass “sitting” in it. This is a characteristic of black holes. A possible explanation for this might be that via elimination of common physical laws, the black hole region could become the gateway to metaphysical dimensions. Cosmos of space and time is described as strong-built, fracture-free in the Qur’an; “You do not see any fault or incongruity in the creation of the all Merciful. Look yet again: can you see any rifts?” (Al-Mulk, 67:3). However, in verses about the apocalypse, cosmic fractures that will occur is constantly repeated; “Day will come, land to be transformed into another, skies to be converted into others” (Ibrahim, 14:48)”On the day when the earth is changed into another earth, and the heavens (also)” (Abraham, 14:48), ”And the sky split asunder, and so, on that day it will be most frail” (Al-Haqqah, 69:16), and “The sky will cleft open thereby” (Al-Muzzammil, 73:18). We can conclude from these verses that new heavens would be created from these “fractures.”

The way that doomsday will actually take place is in the knowledge and control of Our Creator who executes these acts and maintains the order of the universe. Approaches and conclusions made with current physical and cosmic sciences will enable a better understanding of the verses related to doomsday.

The Sun rising in the West and the apocalypse

Can a comet or a planet change the direction of the earth’s rotation by colliding with it? Can the earth change direction and start to rotate from East to West instead of West to East? A catastrophic event like this may cause colossal destruction and end the lives of many organisms. As a matter of fact, a comet impact in recent years was detected to slow down the rotational speed of planet Jupiter.

Venus is a mysterious planet on many levels. For example it rotates in the opposite direction compared to other planets. Sun rises in the West on Jupiter. Dense rock and dust layers of Venusian atmosphere is theorized to be formed as a result of a collision, and because of this collision, it is thought to have started spinning in the opposite direction. A day in Venus is longer than a year. In other words Venus revolves around the Sun faster than it rotates around itself.

Bediuzzaman Said Nursi explains the sun rising in the West rather metaphorically as follows:

“While God knows best, the Qur’an, which is in effect the intellect of the earth, will disappear from its head at the end of time and, as a result, the earth will go mad. With Divine leave, it will collide with another planet and its rotation will be reversed. Through Divine Will, its journey from west to east will be reversed from east to west, and the sun will start to rise in the west. Truly, if the gravity of the Qur’an, which is the firm rope of God that binds the earth to the sun and the ground to the Divine Supreme Throne, is broken, the tether holding the earth will come unfastened. The earth will consequently become dizzy and deranged: on account of the reversal of its usual motion, the sun will rise in the west. Through its collision with another planet, Doomsday will begin at the Divine command.” (The Rays, p. 365)

Whichever way the earth comes to an end, even if the universe is not destroyed by an external destructive event, an apocalypse is foretold as something that will eventually happen with some mind-blowing descriptions in the Qur’an. What science speaks of black holes and other astrophysical possibilities in the universe seems to confirm these descriptions:

When the sun is folded up, and when the stars fall, and when the mountains are set moving. (At-Takwir, 81:1-3)
When heaven is cleft open, and when the stars fall in disorder and are scattered, and when the seas burst forth. (At-Taqwir, 81:1-3)

When a honeybee discovers a new source of honey within about ten metres of the hive, she returns to the hive and regurgitates drops of honey which are eagerly drunk by other bees. Then, in order to indicate the source of the drops they have just drunk, she performs an interesting sequence of movements we call the ‘round dance’. She dances round in a circle, first in one direction, then reversing and going round in the opposite direction, again reversing and so on. During the performance, other bees follow her about, holding their antenna against her abdomen. After the dance, she flies back to the food source, normally a particular flower or group of flowers. The other bees who followed the dance do not fly after her but fly out in all directions. However, fairly soon, a great number of them find the new source. They do so because they have smelt the scent of the flowers that clung to the dancer’s body and so to recognize the right kind of flower. Observing this procedure of the bees’ communication with admiration, Frisch reported that the ‘round dance’ tells the other bees to go out and search in the near neighbourhood of the hive; and the scent on the dancer’s body tells them which flowers to look for. In one experiment, bees informed by a dancer at once found the right flowers in a section of Munich Botanical Gardens where 700 different plant species were blooming.

But honeybees search for food at a greater distance than 10 metres. They have been observed to fly more than 13 km in search of honey. Remembering the average that a honeybee is only about 13 mm long, that 13 km for a bee is the equivalent of about 1,600 km for a human being. It is clear that, even for distances considerably less than 13 km, the round dance would not be much use. If the discoverer of a new food source informed the other bees to go out and search in all directions for over several kilometres, they would never find the flowers. Thus, when a bee finds food at a considerable distance, say over 100 metres from the hive, she returns to the hive, offers the honey she has found, and then performs a different kind of special dance. She dances along in a straight line for a certain distance, wagging her tail vigorously and buzzing away by means of slight vibrations of the muscles that flap her wings in flight. At the end of this wagging run, she stops buzzing and wagging her tail, circles round to one side back to where she started, does another wagging run, circles round to the opposite side, does a third wagging run and so on. This sequence of movements is called ‘tail-wagging dance’. Showing special interest in wagging runs, a number of other bees follow her round. It is known that bees cannot hear sounds in the air, however they can feel the buzzing vibrations through the surface on which the dance is performed. Like the round dance the ‘tail-wagging’ dance tells the followers of the dance that there is food available, and what flowers to look for, from the smell. But it tells them much more than this; it tells them precisely how far away the flowers are, and in exactly what direction. And so, the bees who study the dance can fly with precision to the spot indicated, even at a distance of kilometers, and find the honey-bearing flowers.

The distance to the food is conveyed by the tempo of the dance. A quick-step tempo means a relatively nearby food source, a slow tempo means a more distant one. More precisely as the distance increases, so does the duration of each wagging run. The bees who follow the dance study several wagging runs and then appear to calculate the average duration which they then translate into distance by a mathematical rule.

The ‘tail-wagging dance’ is sometimes done on a horizontal surface just outside the hive. When this happens, the dancer indicates the direction of food by aiming her run in exactly the direction of the food. She can do this if she can see the sun (or the polarized light of the blue sky, which indicates the position of the sun to bees, though not to us). So, actually she is taking up a position in which she sees the sun as the same angle as during her flight to the honey source. The wagging run makes the same angle with the sun on her outward flight did. But the dance is normally performed in the dark inside the hive, on the vertical surface of the honeycomb. Here the angle between the flight path and the sun is translated into the angle between the wagging run and the vertical direction straight upwards.

Another remarkable fact about the bees communication is that if the bee reached her goal (and returned from it) by an L-shaped detour, she uses the angles and lengths of the two sections of flight to calculate the true direction of the goal by straight-line flight, and this is the direction she conveys in her dance, even when she did not this direct route herself.

As for the bees who are following the dance, they are working literally in the dark and can only use touch to find out the angle of the dancer’s wagging run against the vertical. They translate this back into a visual angle with the sun, fly off in this direction for the distance signaled by the wagging run tempo, and look for the flowers of the scent they smelt on the dancer.

So far we have described the language of the Carniolan race of honeybees according to the findings of Frisch. Other races have different ‘dialects’. German, North African, Caucasian, Italian honeybees all indicate distance and direction by much shorter dances than the Carniolans. How the honeybees have learned to communicate with each other is certainly remarkable! However, it is not a true language, because the system used by bees, unlike human languages, cannot generate new combination of structures and symbols to describe novel events. One example of their limitation is that bees appear to have no way of communicating height or depth beyond a few meters. Thus, if you take a bee to a source of food in a place, say 10 metres above ground level, she will return to her hive and try to indicate the food source by means of her dance. Then, the other bees will all fly out in the direction she indicated, but they will never find the source. No matter how near the source is, even if it is just above the hive, the result will be the same.
