FUNDAMENTAL FORCES

Fundamental Forces In the Universe

We mentioned that the laws of physics in the universe originated after the Big Bang. These laws are based on the “four fundamental forces” known to modern physics today. These forces were formed along with the formation of the first sub-atomic particles at specifically appointed times in the immediate aftermath of the Big Bang to form the entire order and system of the universe. Atoms, which make up the material universe, owe their existence and extremely even distribution across the universe to the interaction of these forces. These forces are the force of mass attraction known as the gravitational force, the electromagnetic force, the strong nuclear force, and the weak nuclear force. All have a distinct intensity and field of impact. The strong and weak nuclear forces operate only at the sub-atomic scale. The remaining two – the gravitational force and the electromagnetic force – govern assemblages of atoms, in other words “matter.” The flawless order on the earth is the outcome of the highly delicate proportion of these forces. A comparison of those forces produces a very interesting result. All the matter that was created and dispersed across the universe following the Big Bang was shaped by the effect of these forces, which have wide gulfs between them. Below are the stunningly different values of these forces shown in international standard units:

These fundamental forces allow the formation of the material universe through a perfect distribution of power. This proportion between the forces is based on such a delicate balance that they can cause the due effect on particles only at these particular proportions.

1. The Giant Power in the Nucleus:
The Strong Nuclear Force

Up to this point, we reviewed how the atom was created moment by moment and the delicate balances acting in this creation. We saw that everything around us, including ourselves, is made up of atoms and these atoms consist of many particles. What then is the force that holds all the particles that form the nucleus of the atom together? This force, which keeps the nucleus intact, and which is the most powerful force defined by the laws of physics, is the “strong nuclear force”.

This force ensures that the protons and neutrons in the nucleus of the atom stay together without flying apart. The nucleus of the atom is formed in this way. This force is so strong that it almost causes the protons and neutrons within the nucleus to bind to each other. This is why the minute particles that possess this force are called “gluon” meaning “glue” in Latin. The strength of this bond is adjusted very sensitively. The intensity of this force has been specifically arranged to provide that the protons and neutrons keep at a certain distance to each other. If this force had been just slightly stronger, the protons and the neutrons would bump into each other. If this force had been slightly weaker, they would be dispersed. This force has just the proper degree required for the formation of the nucleus of the atom after the first seconds of the Big Bang.

The Hiroshima and Nagasaki bombings were indicative of how destructive the strong nuclear force becomes once it is liberated. The only reason atomic bombs, which will be reviewed in more detail in the chapters ahead, are so effective is the liberation of tiny amounts of this force hidden in the nucleus of the atom.

2. Safety Belt of the Atom:
the Weak Nuclear Force

One of the most important factors maintaining order on the earth is the balance within the atom. This balance ensures that things do not suddenly fall apart or emit harmful radiation. The “weak nuclear force” is responsible for this balance between protons and neutrons in the nucleus of the atom. This force plays an important role in maintaining the equilibrium of the nuclei that contain high numbers of neutrons and protons.

As this balance is maintained, a neutron, if required, may be changed into a proton. Since the number of protons in the nucleus changes at the end of this process, the atom changes too and becomes a different atom. Here, the result is very significant. An atom transforms into a different atom without disintegrating and continues its existence. This safety belt protects living organisms against the dangers that would otherwise arise from particles breaking free uncontrollably and giving harm to people.

3. The Force That Keeps Electrons in Orbit:
The Electro-magnetic Force

The discovery of this force ushered in a new age in the world of physics. It was then understood that each particle bears “an electrical charge” according to its own structural characteristics and that a force exists between these electrical charges. This force provides that particles with opposite electrical charges attract each other and particles with the same charge repel each other, therefore ensuring that the protons in the nucleus of the atom and the electrons travelling in the orbits around it attract each other. In this way, the “nucleus” and the “electrons”, the two basic elements of the atom, stay together.

The slightest change in the strength of this force would cause electrons to shoot away from the nucleus or to fall into the nucleus. In both cases, it would become impossible for the atom and therefore, the material universe to exist. Yet, from the first moment this force formed, the protons in the nucleus attracted the electrons at the exact force required for the formation of the atom thanks to the value of this force.

One can stay in an environment without gravity only for a certain period using special equipment. Living beings can only survive in a system where gravity exists.

4. The Force Holding the Universe Together:
The Gravitational Force
Being the only force we can ordinarily perceive, it is also the one about which we know least. Commonly known as gravity, this force is actually called the “mass attraction force”. Although it is the least powerful force compared to the other forces, by it very large masses attract each other. This force is the reason why the galaxies and stars in the universe stay in each other’s orbits. The earth and other planets remain in a certain orbit around the sun again with the help of this gravitational force. We are able to walk on the earth because of this force. If there were a decline in the value of this force, the stars would fall, the earth would be ripped from its orbit and we would be dispersed from the earth into the space. In the case of the slightest increase, the stars would collide with each other, the earth would run into the sun and we would be pulled into the earth’s crust. These may seem very remote possibilities to you now but they would be inevitable if this force had deviated from its present value even for a very short time.
All scientists doing research on this subject admit that the precisely determined values of these fundamental forces are crucial for the existence of the universe.

Supreme design and perfect order prevail in the entire universe governed by these fundamental forces. The Owner of this order is, beyond doubt, Allah, Who created everything flawlessly out of nothing. Isaac Newton (1642-1727), the father of modern physics and celestial mechanics, who is recognized as “one of the greatest scientists who ever lived” draws attention to this fact: “This most beautiful system of the sun, planets, and comets could only proceed from the counsel and dominion of an intelligent and powerful Being. This Being governs all things, not as the soul of the world, but as Lord over all, and on account of His dominion. He is wont to be called Lord God, Universal Ruler.”

Addressing this point, the famous molecular biologist Michael Denton states in his book Nature’s Destiny: How the Laws of Biology Reveal Purpose in the Universe:
If, for example, the gravitational force was a trillion times stronger, then the universe would be far smaller and its life history far shorter. An average star would have a mass a trillion times less than the sun and a life span of about one year. On the other hand, if gravity had been less powerful, no stars or galaxies would have ever formed. The other relationships and values are no less critical. If the strong force had been just slightly weaker, the only element that would be stable would be hydrogen. No other atoms could exist. If it had been slightly stronger in relation to electromagnetism, then an atomic nucleus consisting of only two protons would be a stable feature of the universe-which would mean there would be no hydrogen, and if any stars or galaxies evolved, they would be very different from the way they are. Clearly, if these various forces and constants did not have precisely the values they do, there would be no stars, no supernovae, no planets, no atoms, no life.1
Renowned physicist Paul Davies states his admiration for the predetermined values of the laws of physics in the universe:
When one goes on to study cosmology, incredulity mounts. Recent discoveries about the primeval cosmos oblige us to accept that the expanding universe has been set up in its motion with a cooperation of astonishing precision.2
Supreme design and perfect order prevail in the entire universe constructed on a foundation provided by these fundamental forces. The owner of this order is, beyond doubt, Allah, Who created everything flawlessly out of nothing. Allah, the Lord of all the worlds, holds the stars in their orbits with the weakest of forces, and holds together the nucleus of the minute atom with the strongest of forces. All forces act according to the “measures” He has determined. Allah refers to the order in the creation of universe and the equilibriums “determined most exactly” in one of His verses:

He to whom the dominion of the heavens and the earth belongs. He does not have a son and He has no partner in His dominion. He created everything and determined it most exactly. (Surat al-Furqan: 2)
