Greatest Design: Universe

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 viscosity. 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?

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.

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.

All products of technology make use of friction in one form or the other. The engine of a vehicle functions by help of friction.

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 echoe 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.

"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!" (Surat al-Mulk: 3-4)

In the universe there are unchanging laws that affect all animate as well as inanimate things. Physicists use various constants of physics to explain these unchanging laws. These constants are among the evidence that illustrate the perfect creation of the universe just as it does the perfect creation evident in the beings living therein. If these constants were to change slightly, neither the earth on which we live nor the universe could have existed.

They said 'Glory be to You! We have no knowledge except what You have taught us. You are the All-Knowing, the All-Wise.' (Surat al-Baqara: 32)
