The term "fine-tuning," which began to be used towards the end of the 20th century, represents this truth revealed in the verses. Over the last quarter-century or so, a great many scientists, intellectuals and writers have shown that the universe is not a collection of coincidences. On the contrary, it has an extraordinary design and order ideally suited to human life in its every detail. (See Harun Yahya, The Creation of the Universe and A Chain of Miracles) Many features in the universe clearly show that the universe has been specially designed to support life. The physicist Dr. Karl Giberson expresses this fact thus:

In the 1960s, some physicists observed that our universe appears to have been fine-tuned for the existence of human life.

The Speed of the Big Bang Explosion:

The balances established with the Big Bang, the instantaneous formation of the universe, are one of the proofs that the universe did not come into being by chance. According to the well-known Adelaide University professor of mathematical physics Paul Davies, if the rate of expansion that took place following the Big Bang had been just one in a billion billion parts different
(1/1018), the universe could not have come into being.

The Four Forces:

All physical motion in the universe comes about thanks to the interaction and equilibrium of the four forces recognised by modern physics: gravity, electromagnetic force, strong nuclear force and weak nuclear force. These forces possess extraordinarily different values to one another.


Distances between Celestial Bodies:

The distribution of celestial bodies in space and the enormous spaces between them are essential to the existence of life on Earth. The distances between celestial bodies have been set out in a calculation compatible with a great many powerful universal forces in such a way as to support life on Earth.

Gravity:

- If gravity were stronger, excessive ammonia and methane would collect in the Earth's atmosphere, which would have a most damaging effect on life.
- If it were weaker, the Earth's atmosphere would lose excessive quantities of water, making life impossible.

The Earth’s Distance from the Sun:



- If this were any greater, the planet would grow very cold, the water cycle in the atmosphere would be affected, and the planet would enter an ice-age.
- If the Earth were any closer to the Sun, plants would burn up, the water cycle in the Earth's atmosphere would be irreparably damaged, and life would become impossible.

The Thickness of the Earth’s Crust:

- If the crust were any thicker, then an excessive amount of oxygen would be transferred to it from the atmosphere.
- If it were any thinner, the resulting amount of volcanic activity would make life impossible.


The Speed at which the Earth Revolves

- If this were any slower, the temperature difference between day and night would grow enormously.
- If it were any faster, then atmospheric winds would reach enormous speeds, and cyclones and storms would make life impossible.


The Earth’s Magnetic Field:

- If this were any more powerful, very strong electromagnetic storms would arise.
- If it were any weaker, then the Earth would lose its protection against the harmful particles given off by the Sun and known as solar winds. Both situations would make life impossible.

The Albedo Effect (The Fraction of Light Reflected by the Earth):

- If this were any greater, an ice-age would rapidly result.
- If it were any less, the greenhouse effect would lead to excessive warming. The Earth would first be flooded with the melting of the glaciers, and would then burn up.
The Proportion of Oxygen and Nitrogen in the Atmosphere:
- If this were any greater, vital functions would be adversely accelerated.
- If it were any less, vital functions would adversely slow down.

The Proportion of Carbon Dioxide and Water in the Atmosphere:

- If this were any greater, the atmosphere would overheat.
- If it were any less, the temperature of the atmosphere would fall.


The Thickness of the Ozone Layer:

- If this were any greater, the Earth's temperature would fall enormously.
- If it were any less, the Earth would overheat and be defenceless against the harmful ultraviolet rays emitted by the Sun.


Seismic Activity (Earthquakes):

- If this were any greater, there would be constant upheaval for living things.
- If it were any less, the nutrients at the sea bottom would fail to spread into the water. This would have a damaging effect on life in the seas and oceans and all living things on Earth.


The Earth’s Angle of Tilt:

The Earth has a 23 degree angle of inclination to its orbit. It is this inclination that gives rise to the seasons. If this angle were any greater or any less than it is now, the temperature difference between the seasons would reach extreme dimensions, with unbearably hot summers and bitterly cold winters.


The Size of the Sun:

A smaller star than the Sun would mean the Earth would freeze and a larger star would lead to its burning up.
The Attraction between the Earth and the Moon:
- If this were any greater, the powerful attraction of the Moon would have extremely serious effects on atmospheric conditions, the speed at which the Earth revolves around its own axis and on the ocean tides.
- If it were any less, this would lead to extreme climate changes.


The Distance between the Earth and the Moon:


If they were just a little closer, the Moon would crash into the Earth.
- If they were any further, the Moon would become lost in space.
- If they were even a little closer, the Moon's effect on the Earth's tides would reach dangerous dimensions. Ocean waves would inundate low-lying areas. The friction emerging as a result of this would raise the temperature of the oceans and the sensitive temperature balance essential to life on Earth would disappear.
- If they were even a little further away, the tides would decrease, leading the oceans to be less mobile. Immobile water would endanger life in the seas, and the level of the oxygen we breathe would be endangered.

The Temperature of the Earth and Carbon-Based Life:

The existence of carbon, the basis of all life, depends on the temperature remaining within specific limits. Carbon is an essential substance for organic molecules such as amino-acid, nucleic acid and protein: These constitute the basis of life. For that reason, life can only be carbon-based. Given this, the existing temperature needs to be no lower than -20 degrees and no higher than 1200 Celsius (2480 F). These are just the temperature limits on Earth.
These are just a few of the exceedingly sensitive balances which are essential for life on Earth to have emerged and to survive.
Yet even these are sufficient to definitively reveal that the Earth and the universe could not have come into being as the result of a number of consecutive coincidences.
The concepts of "fine-tuning" and the "anthropic principle" that began to be employed in the 20th century are further evidence of Allah's creation. The harmony and proportion therein were described with magnificent accuracy fourteen centuries ago in the Qur'an.
