It was 3 o’clock in the morning. The rain outside beat on the windows and the loud thunder ripped through the night. A loud knock on the door startled the boy. All alone in the mansion, he was not really expecting anyone this late. But the stranger insistently knocked on the door. The boy got up hesitantly and grabbed the doorknob with shaking hands… Flash forward. He woke up with a scream, drenched in a pool of sweat. “Thank God, it was all a dream.”

I turned off the TV, feeling a mix of boredom and hunger gnawing hunger at the pit of my stomach. I headed down to the kitchen to grab a bite.

The world is full of wonders. We are amazed at how fish swim or how birds fly; by imitating their systems, we attempt to swim or fly. One of our most precious attributes is curiosity. Once I attended an exhibition associated with a popular movie. I was amazed at the power of human imagination and the dreams it can conjure, turning them into reality. The props and costumes used in this movie were displayed lavishly for the curious eyes of the fans and the flash of the cameras. We, as human beings, were being entertained with the products of the human imagination. Even the flow of events that happened at the exhibition, the flashing cameras, the décor and costumes, which seemed so important at that time, were all a design of the human imagination; they were not real. As the actors and actresses took on the personalities of their characters, they not only assumed the role of a movie character, but also became a player in a man-made dream world. We followed the entertainment with curiosity and interest. The characters, the story, the costumes, the light, and sound: all this captivated our attention. As the glow of the entertainment slowly faded off, I began to feel that this popular movie and even the exhibition itself existed within another movie… a more real movie in which we all played our roles.

My favorite pieces in the exhibition were the “magically alive” animated portraits. I couldn’t help but smile when I saw the people in the portraits applauding us, as if we had accomplished some feat. I liked the idea of animated portraits and photos. A picture is ultimately just a 2D image, but an animated image encompasses a third dimension: time. A movie’s ability to capture the charm of time is what appeals to us and captivates our attention.

Early in the morning, I glanced out my window and noticed the autumn leaves falling from the tree in my back yard. About two or three weeks ago they were all green, but now the scene had completely changed. Tinted with different shades of orange, yellow, red and purple, the leaves ruffled on their branches with the whoosh of the light breeze.

I imagined that my window was an animated picture inside my home. There was someone insistently striking His brush against my easel, coloring this picture day by day, moment by moment, and giving it motion for me, making me feel the changes He brought about. Filled with these wondrous thoughts, words fell out of my mouth: “He is truly a magnificent artist.” At the moment, I recalled what the lead character in a movie had said as he looked, bewildered at the harmony of colors in the sky during sunset: “God must have been an artist.”

In order to make an animated picture or create a video sequence, the consecutive pictures or “frames” of a scene must be joined together. If the difference between the capture times of two consecutive frames is too long, the video will not run smoothly, stuttering like an old silent film, with intermittent flickers. Modern day movies use a larger number of frames per unit of time. The greater the number of frames, the smoother the images will appear. When I focused my attention on this outside “movie,” a movie in which I was an actress along with the rest of humanity, I couldn’t help but wonder what the number of frames was. Since we are living in a “perfect” movie, the movie of our world that we see through our eyes everyday must have an infinite number of frames. I contently followed the descent of a snowflake onto my hand. It made me admit once again that we’re part of a great cinematography and screenplay. The producer is not only an artist who covertly paints the pictures with His gentle brush strokes, but is also someone who strings an infinite number of picture frames with great skill and attention to detail, creating the perfect animation of “life.”

Imagine the animation of a falling bird feather; one would need to perform an enormous number of calculations between the sequences of frames. It would be necessary to run many computers in parallel to be able to process such animation in real time. Then I used this same information and applied it to the scene of the falling snowflake. Contemplating the details of each moment within that scenario and considering each moment to be a single frame helps you appreciate the complicated task of stringing these frames together in real time.

When you see a man inscribing circles with a light source you actually see a circle of a light. In fact, you perceive it as a circle because of the speed and the continuity of the motion. Life is analogous to that imaginary circle; it exists because of the continuity of the artist’s efforts. Yes, life as a “perfect” movie is similar to the continuity of this circle of light, because the artist’s magnificent skills continuously color and illuminate each picture frame, stringing them together in a perfect fashion.

Wait, wait, it doesn’t end here. I close my eyes; it is easy for me to see things that happened years ago in all their details. The time I dropped my ice cream on my favorite shirt when I was five, the gift that my brother gave me on my thirteenth birthday, the day I graduated from college… like a movie, I can watch all these whenever I like. This illustrates another issue in video processing, storing the videos, in other words, the frames, in an efficient way so that they can be accessed promptly when needed. I already have a good technique to store the story of my life in my memories. Moreover, in order to remember any sequence, all I need to do is just remember a small detail of the time, an event, or a memento. This is the fastest content-based image retrieval system I have ever seen! No moment of life is wasted and all is saved somewhere, providing relief for the human heart, which is helplessly attracted to eternity. Any art necessitates an exhibition and an audience. Then there must be a place and a time in which the whole movie will be watched again by the audience.

My brain not only stores my memories as videos, but also creates videos as I dream. These are mostly movies in the making; because I can do everything in my dreams, they do not need to be logical. I heard the phrase “Dream Theater” and I smiled. What else can one call a dream other than a grand theater full of surprises? Moreover, although the length of time that a dream takes up is not that long, it still contains a sizeable story that takes up days of real life. It’s one rabbit warren inside another.

As the rain hits the Boston ground, I look outside my window at my moving picture. Through this open window, I also hear the pitter-patter of the falling rain. The smell of wet soil seeps into my room. I shut my eyes and I can repaint the entire picture, using nothing but sounds and smell. What kind of magic is this? I cannot stop myself as I think about Him, the Producer of the real movie of my very existence. After all, I know that He loves me. No matter how busy I am watching man-made movies inside the real movie, I feel the presence of the true artist always with me and the imprint of His ever-lasting art in every moment of my life.

During the Renaissance, science began to develop rapidly. New discoveries about how the universe functions were termed scientific laws, even though they were actually descriptions of what had been observed. Moreover, they were believed to be the main causes. Science gradually became the ultimate explanation of existence, and caused many people to reject religion as obsolete.

All of this changed with the beginning of the twentieth century. Modern physics showed that the universe functions completely differently from what we see in daily life. The basic laws of mechanical physics, once thought to be the creator of the action, turned out to be valid only under certain approximations. The concept of absolute space-time was replaced with a relative and dynamic one. We discovered our limitations in measuring certain physical quantities, and that some particles cannot be observed directly. We recognized that physical laws are not deterministic, and thus cannot predict how a system’s state will change over time. All they can do is present possible alternatives.

Such drastic changes in our understanding forced many to reconsider science’s claim to provide the final explanation of the universe. Today, new discoveries are termed scientific theories. We know that much remains to be discovered, and are expecting more surprises. It also is becoming increasingly harder to claim that one day we will produce a complete description and resolve all mysteries.

In this article, we will illustrate some of the changes in our understanding of the universe and scientific philosophy by analyzing a simple physical event: a falling rock. Since it is an ordinary event, one may think there is nothing mysterious about it. It seems to be a completely deterministic event with no exceptions. One also may think that there is a simple reason for the rock to fall down: the attractive force between objects with mass. As we will see, however, the story turns out to be completely different.

Newton’s Law of Attraction

From experience, we know that a rock left in the air falls to the ground. We also know from astrophysical observations that the Earth circles around the sun. In these examples, the main interaction between the rock and the Earth, or between the Earth and the sun, is called gravity. Through observation, we know that gravity has an attractive nature. Let’s consider the following question, which science should be able to answer if it is the ultimate explanation: Why does a rock fall down?

A nineteenth-century physicist would reply: “A very simple question! Newton’s law of attraction. Objects with mass apply an attractive force to each other, the magnitude of which is proportional to the objects’ mass and inversely proportional to the square of the distance between the objects. Since the Earth and the rock both have mass, they are subject to this law. This is why a rock falls down.”

But this only describes a falling rock. Many who believed this claimed that there could be no change in this scenario, and especially no room for a Creator Who actually let the rock fall down. But, we ask, how do masses apply their forces to each other? Why is this force proportional to mass and inversely proportional to distance?

We do not have to pursue this argument, for we know that the so-called final explanation is incorrect. If the nineteenth-century physicist could have observed more carefully, he or she would have realized that Newton’s law of attraction could not answer all questions involving gravity. For instance, why is light, a particle without mass, deflected by gravity? Such a physicist also could not calculate correctly Mercury’s perihelion around the sun.

We now know that objects with mass do not apply attractive forces to each other. In describing gravity, Newton’s law of attraction can be used as an approximation when gravity is weak. What we see or feel as gravitational attraction is explained more accurately, but completely differently, by the theory of general relativity.

The Theory of General Relativity

What does the theory of general relativity say about a falling rock? According to it, objects with mass curve space-time, a dynamic object, in a definite manner. In this curved space-time, a free particle that is affected only by gravity moves in a geodesic path. In the space-time curved by the Earth, the geodesic path for an object with mass can be calculated through the Earth’s center. As it has mass, a rock should follow this geodesic path. Thus it moves through the Earth’s center, and we see it as falling down.

This description is radically different from the one derived from Newton’s law of attraction. Space-time is considered dynamic, rather than absolute, and is affected by matter. Also, a falling rock is in free motion and is not acted upon by any of force belonging to the Earth.

The general theory of relativity can describe many physical phenomena related to black holes, gravitational collapse, gravitational radiation, and the large-scale structure of the universe that Newton’s theory cannot. It also covers Newton’s law of attraction in a weak gravity approximation, and fits with observations made so far.

However, it has some problems. Starting from its basic principles, it can be proven that the theory cannot describe some physical phenomena properly. Equations governing the dynamics of space-time and matter allow an initial, ordinary configuration of matter to end up in a state that can no longer be analyzed by general relativity. This final state is called a singularity. A black hole’s formation by gravitational collapse is an example of this.

Thus general relativity is also an approximate description that is sensible under certain conditions. Our understanding of gravity and a falling rock is much improved when compared to the past. But this is not the end of the story.

There is another important reason why general relativity is not the final theory of gravity. Other than gravity, three known interactions occur between matter: electromagnetic, strong, and weak. These interactions can be observed in the atomic world, and are described successfully by quantum theory. The basic principles of quantum theory are very different from those of general relativity.

Quantum Theory

While general relativity is deterministic, quantum theory is indeterministic. In general relativity, a system’s state can be specified in the usual physical terms, for instance, by giving positions and velocities. In quantum theory, a system’s state is described in abstract mathematical terms by a vector in a Hilbert space, which has no a priori relation with the physical world. Furthermore, positions and velocities can no longer be known together. The formalisms of two theories are very different and contradictory.

At first, this seems to be a philosophical problem. On a large scale involving planetary distances, quantum effects are negligible and gravity dominates other interactions. But on an atomic scale, gravitational interactions are generically very weak and can be neglected when compared to other interactions. Therefore, quantum theory and general relativity seem to be complementary for a large-scale general relativity. However, quantum theory provides appropriate descriptions on an atomic scale.

Based on these ideas, one may claim that the rather deep philosophical conflict between two successful theories is, for all practical purposes, harmless and unimportant. But this is incorrect, for in some cases both gravitational and quantum effects are not negligible. For instance, a black hole may have an atomic size, which can be described properly by quantum theory. On the other hand, since black holes naturally involve strong gravitational interactions, general relativity plays a crucial role in their description. This is an important feature of black holes, one that makes them interesting objects to study.

The quantum theory of gravity describes both gravitational and quantum effects properly. Apart from the fact that there are few candidates (like string theory), we still do not know this theory’s basic principles, which should cover the principles of quantum theory and general relativity. The two main obstacles to this are that sophisticated (and as yet undeveloped) mathematics are needed to attack theoretical problems, and that direct experimentation is impossible, since such experiments involve energies that cannot be produced on Earth.

This simply means that we do not have a complete description of a rock falling, one of the simplest physical events one can imagine. On the other hand, why is a rather deeper question then describing the event. It seems that such classical deterministic theories as general relativity can answer this question if some basic principles are assumed. But these basic assumptions can be questioned, and it is hard to claim that they are immutable. As discussed earlier, the basic principles of Newton’s theory turn out to be sensible in an approximation involving weak gravity. The existence of such nonphysical states as singularities imply that a similar conclusion holds for general relativity. Therefore, even in classical deterministic theories, the question of why cannot be answered honestly.

The situation in quantum theory is completely different. In classical theories, a system’s state changes over time and in a definite manner. In quantum theory, however, only probabilities of possible changes can be calculated, and the system may change according to one of these alternatives. Furthermore, among the possible alternatives, classically forbidden ones may be present. More important, according to basic quantum theory principles, the question of why a specific alternative is chosen cannot be answered in scientific terms.

It is interesting to see the implications of quantum theory’s uncommon features for our simple example, since the unknown quantum theory of gravity should have all of these indeterministic features. According to general relativity, all rocks left free in the air fall in exactly the same manner. But this description is not completely correct, for general relativity is not the final theory of gravity.

By roughly analyzing the same event from a quantum theory point of view, one can see that, due to seemingly strange quantum effects, a rock left in the air may go up as well as down, although going up is forbidden by general relativity. This seems to conflict with daily experience, and one may wonder why we always see objects left free in the air as falling down but not up. The reason is that for macroscopic objects like rocks, quantum effects are generically very small and a system’s state changes, most probably, as classically expected. Stated differently, the ratio of rocks going up to the ones going down is incredibly small. This is why we believe that every time we let go of a rock it will fall down. However, this does not rule out exceptions.

Conclusion

In this article, we analyzed a simple event to illustrate some of the changes in our understanding of how the universe functions. Many physicists used to believe that the order around us could be explained by assuming simple physical laws. However, the more we learn about the universe, the more we encounter new principles and new surprises-and the more we recognize our ignorance. Furthermore, modern physics states that the universe does not function according to strict causality and determinism.

In light of these developments, it is clear that we should renew our understanding of physical laws and the idea that they have a role in creating the action and the order around us. Being the most fundamental natural science, this conclusion of modern physics also influences other sciences. Therefore, science should be accepted as an important tool for seeking and seeing the beauty of the created order around us, and nothing more.

The Quran calls the attention of human beings to the Divine manifestations on creatures such as the honeybee, ant, gnat and spider and invites them to reflect on and study phenomena like the movements of air, the alternation of day and night and the seasons, and the movements of heavenly bodies. The importance the Qur’an gives to the study of natural events inspired Muslim scientists to undertake investigations using observation and the experimental method – long before these came into use in Europe.

Science passed to Europe through the two centuries of the Crusades, through the universities in al-Andalus and Sicily and the translations made there from Arabic. This was the main factor behind the Renaissance in Europe. Building on (without ever openly acknowledging) the works of Muslim scientists, Western scientists led the way to the birth of modern science. Until correct conclusions were reached about phenomena through observation and experimental methods, the assertions of the ancient Greek philosophers had been accepted as the basic laws of nature. For example, it had been asserted as true without question from the time of Aristotle that the speed of an object’s falling is proportionate to its weight. However, the experiments done by Galileo and Newton proved this to be false. Those experiments showed that- so long as the resistance of air is negligible in proportion to the weight of the object and its vertical cross sectional area – the unhindered movement of an object on the earth is not dependent on its mass. This means that objects of different weight dropped from the same point reach earth at the same time. Such developments in physics led scientists to app rove observation and experiment as a basic rule in establishing natural facts. It was the job of scientists to try to discover the laws and basic truths prevalent in the universe through observation and experiment – empirical methods – while it was the task of philosophers to reflect on and comment on them, in other words, in order to have true conclusions about the universe and the events taking place in it we had to discard all of our preconceptions about them and study nature through empirical methods and then comment on the natural events and the relations between them.

In order to have a clearer understanding of modern science and what it can give us of truth about the universe, let us consider the law of general gravity, which is an undeniably established scientific fact:

Various observations and experiments have shown that any two objects attract each other or exert force upon each other proportionately to their masses and in inverse proportion to the square of the distance between them.

The force of attraction or gravity is the force which is in effect in events such as the falling of an object and the revolving of the earth around the sun. Science presents gravity as if it were the cause of such events. However, what we call the force of gravitation is only a notion which we use to explain those events. That is, there is an attraction observed between objects. In order to explain this attraction, we give it a name like the law or force of gravitation and then think that we have explained the event of attraction.

Science does not know the nature of what it calls the force of gravitation but, starting from the assertion that we have already successfully explained many events whose causes were unknown in the past, claims that it will be explained in the future. Nevertheless, science is unable to explain the real cause of all the events in the universe. What science in fact does is, starting from the recurrence of an event under the same conditions, to make a generalization and call it a law. Then it proceeds to assert that the same event will take place again and again under the same conditions. For example, after observing the falling of objects thrown into the air, it makes a generalization that all objects thrown into the air fall, and expresses this event of falling by a mathematical formula.

It can serve as a simple example to see how science works to calculate and state beforehand how long it takes for an object thrown into the air with a certain force and at a certain angle to fall and at what distance it falls. Since events take place in a cause-and- effect series, knowing what effect or event will take place in the next step does not require understanding why it takes place in that way. Therefore, although we suppose that the law of gravity will be understood as, say, dependent on an exchange between certain particles or the obliquity of spatial time, it will nevertheless remain unexplained through scientific methods why such an exchange takes place or why the spatial time becomes oblique and why that exchange or obliquity occurs according to certain mathematical formulations and thereby objects attract each other. In addition to the fact that why objects attract each other remains unknown, it is also a mystery (and a wonder) that this event of attraction takes place according to a mathematical formula. Because of our familiarity with the events taking place in nature, we ignore the important fact that every thing, every event in nature is a miracle. In order to see why the event of gravitation is a dazzling miracle, we should consider it more closely:

As an example to understand the law of gravity, let us consider the falling of a stone dropped (and then allowed to fall unhindered) from a certain high point. Left unhindered, that stone will realize a certain trajectory as the result of gravity affecting it. It will move faster and faster and finally hit the ground. How the stone will accelerate, how long it will take it to reach the ground and how it will move at every second of its trajectory depends on the stones distance from the centre of the earth, the mass of the earth and the constant of gravity. This means that the stone does not move at random, rather each of its movements during its fall is determined through mathematical formulas. This is an extremely regular movement. From this we inevitably conclude that if the stone does this movement of falling by itself, without an agent directing or determining its trajectory, then the stone must know accurately the constant of gravity, the mass of the earth and its distance from the centre of the earth at each moment of its trajectory, and then move in conformity with that knowledge. Whoever has a bit of intelligence will not attribute to the stone itself such a trajectory, simple in appearance but extremely complex in reality. Indeed, the falling of a stone is so complex a movement that during it all the objects in the universe, every thing with a certain mass, exerts on it certain force of attraction and the stone moves under the influence of all those forces. (Here we do not consider other essential forces such as the electro-magnetic and nuclear ones, which have determining effect on the movement of things. Expressed, again, with certain mathematical formulas, these forces make the movements in the universe even more complex.) That is, in order to determine its trajectory, the stone must know the exact distance between itself and each of about 1080 particles in the universe, calculate accurately at each moment of its trajectory the force of the attraction exerted on it by each of those particles according to the mathematical formula of gravity – a force which changes every moment – and focus all those forces to a single point in consideration of the direction of each. Let alone a stone, even the most advanced computer the size of the universe could not accomplish that. For the position of each of the particles with respect to the stone changes at every moment during its fall. Thus, the simplest-seeming movement in the universe like the falling of a stone requires comprehensive knowledge and mastery of an infinite number of interrelated processes.

Since any event taking place in any part of the universe has connection with each of the particles in the universe and the whole of the universe itself, only one who has perfect knowledge of each of those particles and the universe as a whole, one who sees the whole of the universe with each particle in it, can determine and direct all the movements in the universe. Also, since the law of gravity and all the other physical laws are the same and have the same uniformity throughout the whole of the universe, the one who makes these laws operative in the whole of the universe must be an absolutely powerful one, who dominates each and every thing in the universe. Otherwise, each atom in the universe must have an eye seeing the whole of the universe at the same time, know the position, mass, electrical charge, in short, all the physical features, of each particle in the universe, be aware of all the physical laws and obey the laws itself originated.

Every event and every thing in the universe is interrelated to every other and whatever takes place in the universe takes place according to certain laws. Therefore, it is impossible for even the smallest, most insignificant-seeming event to take place without one with an absolute, perfect knowledge of the universe with all its particles and an absolute power governing it. Said Nursi expresses this fact as follows:

If the existence and operation of the universe is not attributed to God Almighty, then it requires admitting that each particle has the attributes of the Necessarily Existent Being, and that each particle should both dominate and be dominated by all other particles. Again, each particle should have an all-encompassing will and knowledge, for the existence of a single thing is dependent on all things and one who does not own the universe cannot rule a single particle.

After explaining how complex a phenomenon gravitation is, we can go a little further to see the real cause of that phenomenon. The relation sensed between the fall of a stone and the rotation of the moon around the world in a fixed orbit led Newton to discover the law of gravity. Ever since this law received a general welcome, the cause of the falling down of an object thrown into the air has unquestionably been accepted as gravity. However, it is not necessary that the real cause of this movement is the force of the attraction of the earth or the existence of another material cause.

Consider this:

Let us imagine some animate beings living on a two- dimensional table. These living beings are aware of only the table on which they live and completely unaware of the three- dimensional world around them. Someone from the three- dimensional world fires at the table in equal frequencies and makes holes at equal distance from each other. Seeing the holes at equal distances, the animate beings living completely unaware of the three-dimensional world will inevitably conclude that each hole causes another one to be made. Whereas it is some other firing from the outside world who made the holes.

This is how the scientists attributing every thing and event in the universe to the law of causality think about the working of the universe. It is questionable whether the attraction of an object toward another near it (for example, the attraction of a falling stone toward the ground) is because of the objects themselves or there is some other source forcing the objects to such a movement. (The event of attraction is the simplest of the events occurring in the universe. You may consider how a honeybee makes honey or a cow gives milk, events which contain a much greater number of physical interactions, chemical reactions and cause and effect.) In short, since the movement of an object according to the law of gravity is one each moment of which is mathematically described and requires as many masses and distances as the articles in the universe and the distances among them to be known in their mutual, complex relations, there must be One Who is the All-Knowing. This One must also have an absolute will to choose and assign for each event a law out of innumerable ones. The uniformity of the law, that is, all the laws being prevalent throughout the universe calls for the unity of that All-Knowing and All-Willing One, and the obedience of all things, small or great, to those laws demonstrate that that One is also the All- Powerful. Again, the unchangeability or stability of the laws and the magnificent, unchanging order and harmony of the universe show that that One is Self- Subsistent and the All-Subsisting. That means it is that All-Knowing, All-Willing, All-Powerful, Self-Subsistent and All-Subsisting, Single One Who causes a stone to fall. For no one and nothing in the universe has the knowledge, will and power absolutely necessary for the falling of a stone. Every thing and event in the universe is too complex and magnificent for any material cause to bring it about. There is then no way for man other than to admit and recognize the Existence and Unity of God.
