PART 1 PROOFS OF ALLAH'S EXISTENCE

THE CREATION OF THE UNIVERSE and THE EQUILIBRIUM IN THE EXPLOSION

Allah created the heavens and the earth with truth. There is certainly a Sign in that for the believers. (Qur'an, 29:44)

A century ago, the creation of the universe was a concept that astronomers as a rule ignored. The reason was the general acceptance of the idea that the universe existed in infinite time. Examining the universe, scientists supposed that it was just a conglomeration of matter and imagined that it had no beginning. There was no moment of "creation"-a moment when the universe and everything in it came into being.

This notion of an infinite universe fit in very well with atheism. It is not hard to see why. To hold that the universe had a beginning could imply that it was created and that, of course requires a Creator-that is, Allah. It was much more convenient and safer to circumvent the issue by putting forward the idea that "the universe exists for eternity", even though there was not the slightest scientific basis for making such a claim.

Unsurprisingly, the discoveries in the 20th century proved with compelling evidence that at some time, all the matter in the universe was compacted in a single point-mass that had "zero volume" because of its immense gravitational force. Our universe came into being as the result of the explosion of this point-mass that had zero volume. This explosion has come to be called the "the Big Bang" and its existence has repeatedly been confirmed by observational evidence.

There was another truth that the Big Bang pointed to. To say that something has zero volume is tantamount to saying that it is "nothing". The whole universe was created from this "nothing". And furthermore this universe had a beginning, contrary to the view of materialism, which holds that "the universe has existed for eternity".

With the Big Bang's victory, the myth of 'eternal matter' that constituted the basis of the materialist philosophy is thrown into the trash-heap of history. What, then, was before the Big Bang and what was the power that brought the universe into 'being' with this big explosion when it was previously 'non-existent'? This question certainly implies, though terribly disturbing for the materialists, the existence of a Creator. The renowned atheist philosopher Antony Flew comments on the issue. He says:

Notoriously, confession is good for the soul. I will therefore begin by confessing that the Stratonician atheist has to be embarrassed by the contemporary cosmological consensus. For it seems that the cosmologists are providing a scientific proof, that the universe had a beginning. So long as the universe can be comfortably thought of as being not only without end but also without beginning, it remains easy to urge that its brute existence, and whatever are found to be its most fundamental features, should be accepted as the explanatory ultimates. Although I believe that it remains still correct, it certainly is neither easy nor comfortable to maintain this position in the face of the Big Bang story.¹

Many scientists who do not blindly condition themselves to be atheists have admitted the role of an almighty Creator in the creation of the universe. This Creator must be a Being Who has created both matter and time, yet Who is independent of both. Well-known astrophysicist Hugh Ross has this to say:

If time's beginning is concurrent with the beginning of the universe, as the space-theorem says, then the cause of the universe must be some entity operating in a time dimension completely independent of and preexistent to the time dimension of the cosmos. This conclusion tells us that God is not the universe itself, nor is God contained within the universe.²

Yes, matter and time are created by the almighty Creator Who is independent of all these notions. This Creator is Allah, Who is the Lord of the heavens and the earth.

In truth, the Big Bang caused much greater trouble for the materialists than the above confessions of the atheist philosopher, Antony Flew. For the Big Bang not only proves that the universe was created out of nothing, but also that it was brought into being in a very planned, systematic and controlled manner.

The Big Bang took place with the explosion of the point which contained all the matter and energy of the universe and its dispersion into space in all directions with a terrifying speed. Out of this matter and energy, there came about a great balance containing galaxies, stars, the sun, the earth and all other heavenly bodies. Moreover, laws were formed called the 'laws of physics', which are uniform throughout the whole universe and do not change. All these indicate that a perfect order arose after the Big Bang.

Explosions that we are normally familiar with, however, do not bring about order. All of the observable explosions tend to harm, disintegrate, and destroy what is present. For example, the atom and hydrogen bomb explosions, fire-damp explosions, volcanic explosions, natural gas explosions, solar explosions: they all have destructive effects.

Sir Fred Hoyle, the world-renowned astronomer, who finally had to accept the Big Bang theory after many years of opposition, expresses this situation very well. He says:

The big bang theory holds that the universe began with a single explosion. Yet as can be seen, an explosion merely throws matter apart, while the big bang has mysteriously produced the opposite effect - with matter clumping together in the form of galaxies.³

Another aspect of this extraordinary order formed in the universe following the Big Bang is the creation of a 'habitable universe'. The conditions for the formation of a habitable planet are so many and so complex that it is impossible to think that this formation is coincidental.

Paul Davies, a renowned professor of theoretical physics, calculated how 'fine tuned' the pace of expansion after the Big Bang was, and he reached an incredible conclusion. According to Davies, if the rate of expansion after the Big Bang had been different even by the ratio of one over a billion times a billion, no habitable star type, and therefore any form of life, would have been formed. Paul Davies says:

Careful measurement puts the rate of expansion very close to a critical value at which the universe will just escape its own gravity and expand forever. A little slower and the cosmos would collapse, a little faster and the cosmic material would have long ago completely dispersed. It is interesting to ask precisely how delicately the rate of expansion has been 'fine-tuned' to fall on this narrow dividing line between two catastrophes. If at the time the pattern of expansion was already firmly established, the expansion rate had differed from its actual value by more than one in a billion billion, it would have been sufficient to throw the delicate balance out. The big bang was not, evidently, any old bang, but an explosion of exquisitely arranged magnitude.⁴

The laws of physics that emerged together with the Big Bang have not changed at all over a period of 15 billion years. Furthermore, these laws stand on calculations so scrupulous that even a millimetre's variation from their current values can result in the destruction of the whole structure and configuration of the universe.

We created the heavens and the earth, and everything between them, in six days and We were not affected by fatigue. (Qur'an, 50:38)

The famous physicist Prof. Stephen Hawking states in his book A Brief History of Time, that the universe is set on calculations and balances more finely tuned than we can conceive. Hawking states with reference to the rate of expansion of the universe:

If the rate of expansion one second after the big bang had been smaller by even one part in a hundred thousand million million, the universe would have recollapsed before it ever reached its present size.⁵

Paul Davies also explains the unavoidable consequence to be derived from these incredibly precise balances and calculations:

It is hard to resist the impression that the present structure of the universe, apparently so sensitive to minor alterations in the numbers, has been rather carefully thought out… The seemingly miraculous concurrence of numerical values that nature has assigned to her fundamental constants must remain the most compelling evidence for an element of cosmic design.⁶

In relation to the same fact, an American professor of Astronomy, George Greenstein, writes in his book The Symbiotic Universe:

How could this possibly have come to pass [that the laws of physics conform themselves to life]?.. As we survey all the evidence, the thought insistently arises that some supernatural agency must be involved.7

In fact in order to recognize that the universe is not a "product of coincidences" one does not really need any of these calculations at all. Simply by looking around himself, a person can easily perceive the fact of creation in even the tiniest details of what he sees. How could a universe like this, perfect in its systems, the sun, the earth, people, houses, cars, trees, flowers, insects, and all the other things in it ever have come into existence as the result of atoms falling together by chance after an explosion? Every detail we peer at shows the evidence of Allah's existence and supreme power. Only people who reflect can grasp these signs.

In the creation of the heavens and earth, and the alternation of the night and day, and the ships which sail the seas to people's benefit, and the water which Allah sends down from the sky- by which He brings the earth to life when it was dead and scatters about in it creatures of every kind-and the varying direction of the winds, and the clouds subservient between heaven and earth, there are Signs for people who use their intellect. (Qur'an, 2: 164)

Doubtlessly, the design of the universe is evidence of Allah's power to establish. The precise balances and all the human beings and other creatures are the evidence of Allah's supreme power and act of creation. This result discovered by modern science is just a reworking of a truth revealed fourteen centuries ago in the Qur'an:

Your Lord is Allah, Who created the heavens and the earth in six days and then settled Himself firmly on the Throne. He covers the day with the night and, each pursuing the other urgently; and the sun and moon and stars are subservient to His command. Both creation and command belong to Him. Blessed be Allah, the Lord of all worlds. (Qur'an, 7:54)

GREATEST DESIGN: UNIVERSE

"He Who created the seven heavens in layers. You will not find any flaw in the creation of the All-Merciful. Look again-do you see any gaps? Then look again and again. Your sight will return to you dazzled and exhausted!" (Qur'an, 67:3-4)

There are unchangeable fundamental laws in the universe, which affect all animate and inanimate beings alike. These laws are proofs that illustrate the perfection in the creation of the universe just as are the flawless creatures that live therein. Today, these hints are presented to us as laws of physics as discovered largely by physicists. The laws ordinarily accepted as 'laws of physics' are nothing but the evidence of the perfection in creation of Allah. (For detailed information refer to: Harun Yahya, The Creation of the Universe).

Let us give just a few examples of the perfection of design in the universe.

For instance, let us examine one of a dozen crucial properties of rainwater: the 'viscosity of water'.

Different liquids have different degrees of velocity. However, the viscosity of water is perfect for the use of all creatures. If it was a little higher than it is, plants could not have used it for transporting the nutrients vitally important for survival within their capillary tubes.

If the viscosity of water were lower than it is, the flow of rivers would have been a great deal different, hence the mountain formations would have changed, valleys and plateaus would not have formed, and rocks could not have disintegrated to form soil.

Water also facilitates the circulation of the red blood cells that defend our bodies against microbes and dangerous substances. If water's viscosity were greater, the movement of these cells within the vessels would have been totally impossible, the heart would have been overwhelmed in pumping the blood and would possibly have failed to obtain the energy necessary for this job.

Even these few examples sufficiently illustrate that water is a fluid that has been especially created for living beings. Allah, in reference to water, states in a verse:

It is He Who sends down water from the sky. From it you drink and from it come the shrubs among which you graze your herds. And by it He makes crops grow for you and olives and dates and grapes and fruit of every kind. There is certainly a Sign in that for people who reflect. (Surat an-Nahl: 10-11)

Balance Of Forces

What would happen if the gravitational force were greater than it is today? Running or walking would be impossible. Humans and animals would spend much more energy moving about, which would diminish the energy resources of the earth. What if gravity were less powerful? Light objects could not maintain their state of balance. For instance, dust particles picked up by breezes would float in the air for long periods. The speed of raindrops would decrease, and they possibly would evaporate before reaching the ground. Rivers would flow more slowly and hence electricity would not be generated at the same rate.

All this is rooted in the property of the gravitational pull of masses. Newton's law of gravitation states that the force of the gravitational attraction between objects depends on their masses and the distance between them. Hence, if the distance between two stars is increased three times, the gravitational force is decreased by a factor of nine, or if the distance is decreased to half, the force of gravity is increased four times.

This law helps explain the current positions of the earth, moon and planets. If the law of gravitation were different, for example, if the gravitational force were increased as the distance increased, the orbits of the planets would not be elliptical and they would collapse into the sun. If it were weaker, the earth would be set on a course steadily away from the sun. So, if the force of gravity did not have precisely the value it does, the earth would either collide with the sun or be lost in the depths of space.

What If Planck's Constant Were Different?

We encounter different forms of energy all the time. For instance, even the heat that we sense in front of the fire has been created with intricate balances.

In physics, energy is assumed to radiate not as a wave but in small particular amounts called 'quanta'. In calculating the radiant energy, a certain unchanging value called Planck's Constant is used. This number is generally small enough to be considered negligible. This number is one of the fundamental and unchanging indices in nature, which is approximately expressed as 6.626x10-34. In any situation involving radiation, if the energy of a photon is divided by its frequency the result will always equal this constant. All forms of electromagnetic energy, i.e. heat, light, etc. are governed by Planck's Constant.

If this minute number were a different size, then the heat we sense in front of a fire would have been much stronger. Either, at one extreme, the smallest fire could have contained enough energy to burn us up or at the other extreme, even a giant fireball the size of the sun would not have been sufficient to warm the earth.

Frictional Force

Frictional forces are generally considered inconveniences, as they are encountered especially while moving things in our daily lives. However, what would the world be like if frictional forces were completely eliminated? Pens and papers would slip out of our hands and fall down from the table to the floor, tables would slide to the corners of rooms, and in short all objects would fall and roll until everything finally came to a stop at the lowest point. In a frictionless world, all knots would untie, screws and nails would come off, no cars could ever brake, while sounds would never die but echo endlessly.

All of these laws of physics are clear proofs that the universe, just like all the creatures within it, is a product of divine design. In fact, the laws of physics are nothing but human explanations and descriptions of the divine order that Allah has created. Allah has created the unchanging laws of order in the universe and put them in the service of humans so that man will reflect upon and understand the Sovereignty of Allah and give thanks for His blessings.

One can continue giving countless examples in illustration of the order in the creation of Allah. Every created thing since the formation of the universe millions of years ago has been brought into existence by nothing other than the Omniscience and Sovereignty of Allah.

A LIVING PLANET: THE EARTH

Allah created the heavens and the earth with truth. There is certainly a Sign in that for the believers. (Qur'an, 29:44)

The earth is a living planet where many complex systems run perfectly without stopping at all. When compared to other planets, it is evident that in all its aspects the earth is specially designed for human life. Built on delicate balances, life prevails in every spot of this planet, from the atmosphere to the depths of the earth.

Exploring only a few of the millions of these delicate balances would be sufficient to show that the world we live in is specially designed for us.

One of the most important balances in our planet is revealed in the atmosphere that surrounds us. The atmosphere of the earth holds the most appropriate gasses in the most appropriate ratio needed for the survival not only of human beings, but also of all the living beings on the earth.

The 77% nitrogen, 21% oxygen and 1% carbon dioxide as well as other gasses readily available in the atmosphere represent the ideal figures necessary for the survival of living beings. Oxygen, a gas that is vital for living beings, helps food to be burned and converted into energy in our bodies.

If the oxygen quantity in the atmosphere were greater than 21%, the cells in our body would soon start to suffer great damages. The vegetation and hydrocarbon molecules needed for life would also be destroyed. If this quantity were less, then this would cause difficulties in our respiration, and the food we eat would not be converted into energy. Therefore, the 21% oxygen in the atmosphere is the most ideal quantity determined for life.

No less than oxygen, other gasses like nitrogen and carbon dioxide are also arranged in the ideal quantity for the needs of living beings and the continuity of life. The amount of nitrogen in the atmosphere has the ideal ratio to balance the harmful and burning effects of oxygen. This ratio represents the most appropriate value required for photosynthesis, which is essential for life's energy supply on the earth. Moreover, the amount of carbon dioxide has the most appropriate value that is needed to maintain the stability of the surface temperature of the earth and to prevent heat loss especially at night time. This gas, comprising 1% of the atmosphere, covers the earth like a quilt and prevents the loss of heat to space. If this amount were greater, the temperature of the earth would increase excessively, causing climatic instability and posing a serious threat against living beings.

These proportions remain constant thanks to a perfect system. The vegetation covering the earth converts carbon dioxide to oxygen, producing 190 billion tons of oxygen every day. The proportion of other gasses is always kept constant on the earth by the help of interconnected complex systems. Life is thus sustained.

In addition to the establishment of the ideal gas mixture required for life on the earth, the mechanisms needed to preserve and maintain this order are created alongside with it. Any break in the balance, though instantaneous, or any change in the ratios even for a very short time period, would mean the total destruction of life. Yet, this does not happen. The formation of these gasses in the atmosphere just in the amount people need, and the constant preservation of these ratios indicate a planned creation.

The creation of the heavens and earth is far greater than the creation of mankind. But most of mankind do not know it. (Qur'an, 40:57)

At the same time, the earth has the ideal size in terms of magnitude to possess an atmosphere. If the mass of the earth were a little less, then its gravitational force would be insufficient and the atmosphere would be dispersed in space. If its mass were a little greater, then the gravitational force would be too much and the earth would absorb all gasses in the atmosphere. There is an incredibly high number of conditions required for the formation of an atmosphere such as the one our world currently has and all of these conditions should exist altogether to be able to talk of life.

The creation of these delicate proportions and balances in the sky is mentioned in the 7th verse of Surat ar-Rahman:

He erected heaven and established the balance. (Qur'an, 55:7)

The majority of people spend their lives without being aware of the delicate balances and subtle adjustments in the gas composition of the atmosphere, the distance of the world to the sun or the movements of planets. They are ignorant of the great significance of these balances and adjustments to their own lives. However, even a minor deviation in any one of these arrangements would create very severe problems regarding the existence and survival of humankind.

There are many other balances established on earth for the continuity of life:

For instance, if the surface gravity were stronger than its current value, the atmosphere would retain too much ammonia and methane gasses, which would mean the end of life. If it were weaker, the planet's atmosphere would lose too much water, and life on earth would be impossible.

The thickness of the earth's crust constitutes another one of the delicate balances in the earth. If the earth's crust were thicker, too much oxygen would be transferred from the atmosphere to the crust and this would have severe effects on human life.

If the opposite were true, that is, if the earth's crust were thinner, volcanic and tectonic activity would be too great to permit life on earth.

Another crucial balance for human life is the ozone level in the atmosphere. If it were greater than its current value, the surface temperatures would be too low. If it were less, surface temperatures would be too high, and there would be too much ultraviolet radiation at the surface.

Everything in the heavens and every creature on the earth prostrates to Allah, as do the angels. They are not puffed up with pride. (Qur'an, 16:49)

In fact, the absence of even a single of these balances would set the end to life on earth. However, Allah has created the universe with infinite wisdom and power and designed the earth specially for human life. Despite this fact, the majority of people lead their lives in total ignorance of these events. In the Qur'an, Allah reminds people of His blessings in the 13th verse of Surat al-Fatir:

(Allah) makes night merge into day and day merge into night, and He has made the sun and moon subservient, each one running until a specified time. That is Allah, your Lord. The Kingdom is His. Those you call on besides Him have no power over even the smallest speck. (Qur'an, 35:13)

It is sufficient look at millions of dead planets in space in order to understand that the delicate balances required for life on earth is not a result of random coincidences. The conditions essential for life are too complicated to have been formed 'on their own' and at random, and these conditions are specially created for life alone.

These balances we have briefly described so far are only a few of the millions of intricate, interrelated balances and orders established so that people can live in peace and safety on the earth.

Examining only a part of the balances and harmony on the earth is enough to comprehend the superior being of Allah and grasp the existence of a planned creation in every detail of the universe. It is no doubt impossible for a person or any other living being to build such an enormous balance and order. Nor are the components of this order such as atoms, elements, molecules, and gasses capable of establishing an order based on such intricate and extremely delicate calculations and measurements, and such fine tunings. This is because activities like planning, ordering, arranging, calculating, and proportioning can only be realized by beings that possess wisdom, knowledge and power. The Exalted Being Who orders, plans and balances the entire universe to be fit for life of human beings on a planet like earth and Who sustains it with dramatically delicate measures and balances is Allah, Who has Infinite Wisdom, Knowledge and Power.

In the Qur'an, it is stated that those people who are able to realize these facts are only 'people with intelligence':

In the creation of the heavens and the earth, and the alternation of night and day, there are Signs for people with intelligence: those who remember Allah, standing, sitting and lying on their sides, and reflect on the creation of the heavens and the earth: "Our Lord, You have not created this for nothing. Glory be to You! So safeguard us from the punishment of the Fire." (Qur'an, 3:190-191)

THE HIDDEN POWER IN LIGHTNING

One Bolt Of Lightning Produces More Electricity Than The USA

At night, in heavy rain, the sky is suddenly lit up, followed shortly after by a violent noise. Do you know how the magnificent lightning that so illuminates the sky comes about? Do you know how much light it emits? Or how much heat it gives off?

A flash of lightning is the bright light which forms during the release of the electricity in the atmosphere during rainstorms. But when does this bright light form? Lightning can happen when electrical tension in two separate points in the atmosphere-within a single cloud, or between a cloud and the ground, or between two grounds-reaches a high level.

Light bolts happen in the form of at least two strikes. In the first release a negative (-) charge flows from the cloud to the ground. This is not a particularly bright flash. A number of branches can generally be seen spreading out from the main channel. As this first strike reaches the ground, an opposite charge forms at the point it will hit and a second positive charge-bearing current forms from within that same channel directly to the cloud. The two flashes generally meet about 50 metres above the ground. A short circuit forms at the conjunction between the cloud and the ground, as a result of which a very bright strong electric current heads from inside the channel to the cloud. The potential difference in this current between the cloud and the ground is greater than several million volts.

More Electricity Production Than Thousands Of Generating Stations

The energy given off by a single bolt of lightning is greater than that produced in all the electricity generating stations in America. The temperature in the channel where the lightning forms can be as high as 10,000 degrees Celsius. The temperature in kilns for melting iron is between 1,050 and 1,100 degrees. The heat given off by the smallest bolt of lightning is ten times this. This terrible heat means that lightning can easily burn and destroy all the elements on Earth. To make another comparison, the surface temperature of the Sun is as much as 700,000 degrees. In other words, the temperature of lightning is 1/70th of that of the surface of the Sun. The light emitted by lightning is greater than that given off by 10 million 100-watt bulbs. For purposes of comparison, a single lightning bolt illuminates its surroundings more than if one bulb is lit in every house in Istanbul. Allah draws attention to this wondrous brightness of lightning in the Qur'an,

. . . The brightness of His lightning almost blinds the sight. (Surat an-Nur: 43)

	Splendour Which Arises In Half A Second  •An average streak of lightning can power a 100-watt bulb for more than 3 months. •The air temperature where lightning strikes rises by as much as 25,000 degrees. •It travels at 150,000 km/second. Lightning's average thickness is 2.5-5 cm. •Lightning produces nitrogen molecules, which are important for the survival of the Earth's vegetation cover. •An average lightning strike contains an electrical force of 20,000 amps. A welder uses 250-400 amps to weld steel. •Lightning moves at 150,000 km/second, or half the speed of light, and 100,000 times faster than sound.

The bolt which forms descends to earth very rapidly, at 96,000 kmph. The first strike reaches the conjunction or surface in 20 milliseconds, and the return strike returns to the cloud in 70 microseconds. Lightning lasts a total of up to half a second. The reason for the thunder which accompanies it stems from the sudden heating of the air around the channel. As a result of this, the air expands at a speed greater than that of sound, although the shock wave returns to being a normal sound wave within a few metres. The sound waves are formed according to the later atmospheric air and surface shapes. That is the reason for consecutive thunder and lightning.

When we bear all of these properties of lightning in mind we can see that this phenomenon is a miraculous one. The way that such a tremendous force emerges from positively and negatively charged particles, invisible to the naked eye, shows that lightning is consciously created. Furthermore, the fact that nitrogen molecules, so beneficial to plants, emerge from this force again proves that lightning was created with a particular wisdom. (For details see Harun Yahya, Design in Nature, Taha Publishers, UK, 2001.)

Allah specifically draws our attention to lightning in the Qur'an. The meaning of Surat ar-Rad, one of the Suras of the Qur'an, is actually 'Thunder.' In those verses regarding lightning Allah reveals that He presents lightning to people as a source of fear and hope. Indeed, a lightning strike is a sign that it is about to rain, and rain either brings hope, in the form of plentiful crops, or else frightens people by causing such disasters as flooding or landslides. In Surat ar-Rum Allah reveals that,

Among His Signs is that He shows you lightning, a source of fear and eager hope, and sends down water from the sky, bringing the dead earth back to life by it. There are certainly Signs in that for people who use their intellect. (Surat ar-Rum: 24)

Allah has also revealed that the thunder which arises when lightning strikes glorifies His praise. In that same verse He warns people by stating that when He so wishes He sends lightning to punish unbelievers:

The thunder glorifies His praise, as do the angels, out of fear of Him. He discharges the thunderbolts, striking with them anyone He wills. Yet still they argue about Allah when He is inexorable in His power! (Surat ar-Ra'd:13)

Allah has created a number of signs for us in lightning. We must think and give thanks that thunder, which many people have perhaps never considered in this much detail and which inspires such feelings of fear and hope in man, is a means by which fear of Allah increases and is sent down by Him for specific purposes when He so chooses.

IT IS A SCIENTIFIC FACT THAT THE WORLD COMES INTO EXISTENCE IN OUR BRAINS -1-

When you take a look at the room in which you are sitting, what you see is not the room outside of you, but a copy of the room that exists in your brain. You will never be able to see the original room with your sense organs.

All events and objects that we encounter in real life-buildings, people, cities, cars, places-in fact, everything we see, hold, touch, smell, taste and hear-come into existence as visions and feelings in our brains.

We are taught to think that these images and feelings are caused by a solid world outside of our brains, where material things exist. However, in reality we never see real existing materials and we never touch real materials. In other words, every material entity which we believe exists in our lives, is, in fact, only a vision which is created in our brains.

This is not a philosophical speculation. It is an empirical fact that has been proven by modern science. Today, any scientist who is a specialist in medicine, biology, neurology or any other field related to brain research would say, when asked how and where we see the world, that we see the whole world in the vision center located in our brains.

We acknowledge that all the individual features of the world are experienced through our sense organs. The information that reaches us through those organs is converted into electrical signals, and the individual parts of our brain analyze and process these signals. After this interpreting process takes place inside our brain, we will, for example, see a book, taste a strawberry, smell a flower, feel the texture of a silk fabric or hear leaves shaking in the wind.

We have been taught that we are touching the cloth outside of our body, reading a book that is 30 cm (1 ft) away from us, smelling the trees that are far away from us, or hearing the shaking of the leaves that are far above us. However, this is all in our imagination. All of these things are happening within our brains.

Everything we perceive is specially recreated for us in our brains. Therefore, when we say, "We are aware the world around us," we are talking about copied images of colors and shapes, of sounds and smells.

At this point we encounter another surprising fact; that there are, in fact, no colors, voices or visions within our brain. All that can be found in our brains are electrical signals. This is not a philosophical speculation. This is simply a scientific description of the functions of our percetions. In her book Mapping The Mind, Rita Carter explains the way we perceive the world as follows:

Each one [of the sense organs] is intricately adapted to deal with its own type of stimulus: molecules, waves or vibrations. But the answer does not lie here, because despite their wonderful variety, each organ does essentially the same job: it translates its particular type of stimulus into electrical pulses. A pulse is a pulse is a pulse. It is not the colour red, or the first notes of Beethoven's Fifth-it is a bit of electrical energy. Indeed, rather than discriminating one type of sensory input from another, the sense organs actually make them more alike. 

All sensory stimuli, then enter the brain in more or less undifferentiated form as a stream of electrical pulses created by neurons firing, domino-fashion, along a certain route. This is all that happens. There is no reverse transformer that at some stage turns this electrical activity back into light waves or molecules. What makes one stream into vision and another into smell depends, rather, on which neurons are stimulated.¹

In other words, all of our feelings and perceptions about the world (smells, visions, tastes etc.) are comprised of the same material, that is, electrical signals. Moreover, our brain is what makes these signals meaningful for us, and interprets these signals as senses of smell, taste, vision, sound or touch. It is a stunning fact that the brain, which is made of wet meat, can know which electrical signal should be interpreted as smell and which one as vision, and can convert the same material into different senses and feelings.

It's Not Our Eyes That See, It Is Our Brain

The CEO of a company might consider the company building, his car in the parking lot, his house by the beach, his yacht, and all the people who work for him, his lawyers, his family, and his friends to be outside of his body. However, all of these things are merely visions formed in his skull, in a tiny part of his brain.

Because of the indoctrination that we receive throughout our lives, we imagine that we see the whole world with our eyes. Eventually, we usually conclude that our eyes are the windows that open up to the world. However, science shows us that we do not see through our eyes. The millions of nerve cells inside the eyes are responsible for sending a message to the brain, as if down a cable, in order to make "seeing" happen. If we analyze the information we learned in high school, it becomes easier for us to understand the reality of vision.

The light reflecting off an object passes through the lens of the eye and causes an upside-down image on the retina at the back of the eyeball. After some chemical operations carried out by retinal rods and cones, this vision becomes an electrical impulse. This impulse is then sent through connections in the nervous system to the back of the brain. The brain converts this flow into a meaningful, three-dimensional vision.

For example, when you watch children playing in a park, you are not seeing the children and the park with your eyes, because the image of this view forms not before your eyes, but at the back of your brain.

Even though we have given a simple explanation, in reality the physiology of vision is an extraordinary operation. Without fail, light is converted into electrical signals, and, subsequently, these electrical signals reveal a colorful, shining, three-dimensional world. R. L. Gregory, in his book Eye and Brain: The Psychology of Seeing, acknowledges this significant fact, and explains this incredible structure:

We are given tiny distorted upside-down images in the eyes, and we see separate solid objects in surrounding space. From the patterns of simulation on the retinas we perceive the world of objects, and this is nothing short of a miracle.²

When you watch children playing in a park, you are not seeing the children and the park with your eyes, because the image of this view forms not before your eyes, but at the back of your brain.

All of these facts lead to the same conclusion. Throughout our lives, we always assume that the world exists outside of us. However, the world is within us. Although we believe that the world lies outside us, it is in the smallest part of our brain. For example, the CEO of a company might consider the company building, his car in the parking lot, his house by the beach, his yacht, and all the people who work for him, his lawyers, his family, and his friends to be outside of his body. However, all of these things are merely visions formed in his skull, in a tiny part of his brain.

He is unaware of this fact and, even if he knew, would not bother to think about it. If he stood proudly next to his latest-model luxury car, and the wind blew a piece of dust or a small object into his eye, he might gently scratch his itching, open eye and notice that the "material things" he saw moved upside down or to the sides. He might then realize that material things seen in the environment are not stable.

What this demonstrates is that every person throughout his or her life witnesses everything inside their brain and cannot reach the specific material objects that supposedly cause their experiences. The images we see are copies in our brains of the objects that we assume to exist outside of us. We can never know to what extent these copies resemble the originals, or whether or not the originals even exist.

Although German psychiatry professor Hoimar Von Ditfurth is a materialist, he acknowledges this fact about scientific reality:

No matter how we put the argument, the result doesn't change. What stands before us in full shape and what our eyes view is not the "world". It is only its image, a resemblance, a projection whose association with the original is open to discussion.³

For example, when you take a look at the room in which you are sitting, what you see is not the room outside of you, but a copy of the room that exists in your brain. You will never be able to see the original room with your sense organs.

How Can A Bright And Colorful Image Appear In Your Dark Brain?

Every person throughout his or her life witnesses everything inside their brain and cannot reach the specific material objects that supposedly cause their experiences.

There is another point that should not be neglected; light cannot pass through the skull. The physical area in which the brain is located is completely dark, and light cannot possibly penetrate it. However, incredible as it may seem, it is possible to observe a bright and colorful world in this total darkness.Colorful natural beauty, bright sights, all the tones of the color green, the colors of fruits, the designs of flowers, the brightness of the sun, people walking on a busy road, fast cars in traffic, clothes in a shopping mall-are all created in the dark brain.

Imagine a barbecue burning in front of you. You can sit and watch the fire for a long time, but throughout this entire time, your brain never deals with the original of light, brightness or heat from the fire. Even when you feel its heat and see its light, the inside of your brain remains dark and maintains a constant temperature. It is a profound mystery that, in the darkness, the electrical signals turn into colorful, bright visions. Anyone who thinks deeply will be amazed by this wondrous occurrence.

Light Is Also Composed In Our Brain

While discussing what science has discovered about vision, we mentioned that the light we receive from the outside gives rise to some movements of the eye cells, and these movements form a pattern from which our visual experience emerges. However, there is another point that we need to make: Light, as we perceive it, does not reside outside of our brain. The light we know and understand is also formed within our brain. What we call light in the outside world, which is supposedly outside our brains, consists of electromagnetic waves and particles of energy called photons. When these electromagnetic waves or photons reach the retina, light, as we experience it, begins to come into existence. This is the way light is described in physical terms:

The term "light" is used for electromagnetic waves and photons. The same term is used in physiology, as the feeling experienced by a person when electromagnetic waves and photons strike the retina of the eye. In both objective and subjective terms, "light" is a form of energy coming into existence in the eye of a person, which a person becomes aware of through the retina by the effects of vision.⁴

Consequently, light comes into existence as a result of the effects that some electromagnetic waves and particles cause in us. In other words, there is no light outside our bodies which creates the light we see in our brains. There is only energy. And when this energy reaches us we see a colorful, bright, and light-filled world. We can therefore conclude that everything we see merely exists in our brains. This is a scientific truth, proven with scientific evidence.

	Say: “What do you think? If Allah made it permanent night for you till the Day of Rising, what god is there other than Allah to bring you light? Do you not then hear?” (Qur’an, 28:71)

IT IS A SCIENTIFIC FACT THAT THE WORLD COMES INTO EXISTENCE IN OUR BRAINS -2-

What a human being would refer to as "my life" is a collection of all perceptions being put together in a meaningful way and watched from a screen in the brain, and one can never come out of one's brain.

When you look out of the window, you think that you see an image with your eyes, as this is the way that you have been taught to think. However, in reality this is not how it works, because you do not see the world with your eyes. You see the image created in your brains. This is not a prediction, nor a philosophical speculation, but the scientific truth. Everything we perceive takes place in our brains, and that we have no need for the outside world or material beings to experience these perceptions.

We Hear All Types Of Sound In Our Brains

Despite the volume of the sounds you hear, the interior of your brain is actually very quiet. However, you hear noise, such as voices, very clearly in your brain.

The hearing process also operates in a similar manner to the visual process. In other words, we hear sounds in our brains in the same way that we see the view of the outside world in our brains. The ear captures the sounds around us and delivers them to the middle ear. The middle ear amplifies the sound vibrations and delivers them to the inner ear. The inner ear transforms these sound vibrations into electric signals, on the basis of their frequency and intensity, and then transmits them to the brain. These messages in the brain are then sent to the hearing center where the sounds are interpreted. Therefore, the hearing process takes place in the hearing center in essentially the same way that the seeing process takes place in the seeing center.

Therefore, actual sounds do not exist outside our brains, even though there are physical vibrations we call sound waves. These sound waves are not transformed into sounds outside or inside our ears, but rather inside our brains. As the visual process is not performed by our eyes, neither do our ears perform the hearing process. For example, when you are having a chat with a friend, you observe the sight of your friend in your brain, and hear his or her voice in your brain. As the view in your brain is formed, you will have a deep feeling of three dimensions, and your friend's voice is also heard with a similar feeling of depth. For example, you could see your friend as being a long way from you, or sitting behind you; accordingly you feel his voice as if it is coming from him, from near you or from your back. However, your friend's voice is not far away or behind you. It is in your brain.

The smell molecules never actually reach the brain. In our sense of smell, it is only electrical signals which reach the brain, as happens with sound and sight.

The extraordinariness about the real nature of the sound you hear is not limited to this. The brain is actually both lightproof and soundproof. Sound never in fact reaches the brain. Therefore, despite the volume of the sounds you hear, the interior of your brain is actually very quiet. However, you hear noise, such as voices, very clearly in your brain. This is an extraordinary fact. The electrical signals that reach the brain are heard in your brain as sound, for example the sound of a concert in a stadium filled with people.

All Smells Occur In The Brain

If someone is asked how he senses the smells around him, he would probably say "with my nose". However, this answer is not the right one, even though most people would instantly conclude that it was the truth. Gordon Shepherd, a professor of neurology from Yale University, explains why this is incorrect:

We think that we smell with our noses, [but] this is a little like saying that we hear with our ear lobes.¹

Our sense of smell works in a similar mechanism to our other sense organs. In fact, the only function of the nose is its ability to act as an intake channel for smell molecules. Volatile molecules such as vanilla, or the scent of a rose, come to receptors located on hairs in a part of the nose called the epithelium and interact with them. The result of the interaction of the smell molecules with the epithelium reaches the brain as an electric signal. These electric signals are then perceived as a scent by the brain. Thus, all smells which we interpret as good or bad are merely perceptions generated in the brain after the interaction with volatile molecules has been transduced into electric signals. The fragrance of perfume, of a flower, of a food which you like, of the sea-in short all smells you may or may not like-are perceived in the brain. However, the smell molecules never actually reach the brain. In our sense of smell, it is only electrical signals which reach the brain, as happens with sound and sight. 

George Berkeley, a philosopher who has realized the importance of this truth, says "At the beginning, it was believed that colors, odors, etc., 'really exist,' but subsequently such views were renounced, and it was seen that they only exist in dependence on our sensations."²

Michael Posner, a psychologist and Marcus Raichle, a neurologist from Washington University comment on the issue of how sight and other senses occur, even in the absence of an external stimulus:

Open your eyes, and a scene fills your view effortlessly; close your eyes and think of that scene, and you can summon an image of it, certainly not as vivid, solid, or complete as a scene you see with your eyes, but still one that captures the scene's essential characteristics. In both cases, an image of the scene is formed in the mind. The image formed from actual visual experiences is called a "percept" to distinguish it from an imagined image. The percept is formed as the result of light hitting the retina and sending signals that are further processed in the brain. But how are we able to create an image when no light is hitting the retina to send such signals?³

If the taste nerves in your brain were cut off, it would be impossible for the taste of anything you eat to reach your brain, and you would entirely lose your sense of taste.

There is no need for an external source to form an image in your mind. This same situation holds true for the sense of smell. In the same way as you are aware of a smell which does not really exist in your dreams or imagination, you cannot be sure whether or not those objects, which you smell in real life, exist outside you. Even if you assume that these objects exist outside of you, you can never deal with the original objects.

All Tastes Occur In The Brain

The sense of taste can be explained in a manner similar to those of the other sense organs. Tasting is caused by little buds in the tongue and throat. The tongue can detect four different tastes, bitter, sour, sweet and salty. Taste buds, after a chain of processes, transform sensory information into electrical signals and then transfer them to the brain. Subsequently, those signals are perceived by the brain as tastes. The taste that you experience when you eat a cake, yogurt, a lemon or a fruit is, in reality, a process that interprets electrical signals in the brain.

An image of a cake will be linked with the taste of the sugar, all of which occurs in the brain and everything sensed is related to the cake which you like so much. The taste that you are conscious of after you have eaten your cake, with a full appetite, is nothing other than an effect generated in your brain caused by electrical signals. You are only aware of what your brain interprets from the external stimuli. You can never reach the original object; for example you cannot see, smell or taste the actual chocolate itself. If the taste nerves in your brain were cut off, it would be impossible for the taste of anything you eat to reach your brain, and you would entirely lose your sense of taste. The fact that the tastes of which you are aware seem extraordinarily real should certainly not deceive you. This is the scientific explanation of the matter.

If our fingertips are given a stimulus in a different manner, we can sense entirely different feelings. Today this can be done by mechanical simulators. With the help of a special glove, a person can feel the sensation of stroking a cat, shaking hands with someone, washing his hands, or touching a hard material, even though none of these things may be present.

The Sense Of Touch Also Occurs In The Brain

The sense of touch is one of the factors which prevents people from being convinced of the aforementioned truth that the senses of sight, hearing and taste occur within the brain. For example, if you told someone that he sees a book within his brain, he would, if he didn't think carefully, reply "I can't be seeing the book in my brain-look, I'm touching it with my hand". Or, if we said "we cannot know whether the original of this book exists as a material object outside or not", again the same superficially minded person might answer "no, look, I'm holding it with my hand and I feel the hardness of it-that isn't a perception but an existence which has material reality".

When you touch a material object, you sense whether it is hard, soft, wet, sticky or silky in the brain. The effects that come from your fingertips are transmitted to the brain as an electrical signal and these signals are perceived in the brain as the sense of touch.

However, there is a fact that such people cannot understand, or perhaps just ignore. The sense of touch also occurs in the brain as much as do all the other senses. That is to say, when you touch a material object, you sense whether it is hard, soft, wet, sticky or silky in the brain. The effects that come from your fingertips are transmitted to the brain as an electrical signal and these signals are perceived in the brain as the sense of touch. For instance, if you touch a rough surface, you can never know whether the surface is, in reality, indeed a rough surface, or how a rough surface actually feels. That is because you can never touch the original of a rough surface. The knowledge that you have about touching a surface is your brain's interpretation of certain stimuli. This important truth, which needs careful consideration, is expressed by twentieth century philosopher Bertrand Russell:

As to the sense of touch when we press the table with our fingers, that is an electric disturbance on the electrons and protons of our fingertips, produced, according to modern physics, by the proximity of the electrons and protons in the table. If the same disturbance in our finger-tips arose in any other way, we should have the sensations, in spite of there being no table.⁴

The point that Russell makes here is extremely important. In fact, if our fingertips are given a stimulus in a different manner, we can sense entirely different feelings. Today this can be done by mechanical simulators. With the help of a special glove, a person can feel the sensation of stroking a cat, shaking hands with someone, washing his hands, or touching a hard material, even though none of these things may be present. In reality, of course, none of these sensations represent occurrences in the real world. This is further evidence that all the sensations felt by a human being are formed within the mind.
