This article examines how amazingly fine-tuned the laws of physics which govern the universe are that even a well respected secular scientist has commented that the evidence “suggests that a super intellect has monkeyed with physics.”


 

Introduction

There are four fundamental forces of physics in the universe:  1) gravity2) electromagnetism3) the strong nuclear force and 4) the weak nuclear force

Not only must all of the fundamental forces operate individually within just-right parameters, but all four forces must work perfectly together for life to be possible anywhere in the universe.

 

A Just-Right Force of Gravity

        Gravity Probe B Satellite >>

Gravity causes the moon to orbit the earth, the planets to orbit the sun, the sun to orbit the center of the Milky Way galaxy and the Milky Way to orbit the Local Group of galaxies, and so on. Gravity also keeps the earth tilted at 23.5° and keeps the earth from rotating too quickly.  The gravitational force that the moon exerts on Earth produces the ocean tides which keep Earth’s oceans from becoming stagnant and polluted.

If the force of gravity was slightly stronger than it is, stars would burn their nuclear fuel too quickly and too unevenly to support life. If the force of gravity was slightly weaker than it is, matter would not clump together to form larger structures (e.g., moons and planets) and stars would not form or burn nuclear fuel.

The force of gravity must be just-right for life to exist anywhere in the universe.

 

A Just-Right Electromagnetic Force

The electromagnetic force is what causes certain life essential chemicals to form.

If the electromagnetic force was stronger than it is, some of the chemicals essential for life (e.g., carbon and oxygen) would not bond together and other life-essential elements would be too unstable for fission to occur. If the electromagnetic force were weaker than it is, chemicals could not bond properly and there would be insufficient carbon and oxygen to support life.

The electromagnetic force must be just-right for life to exist anywhere in the universe.

A Just-Right  Strong Nuclear Force

The strong nuclear force keeps protons and neutrons inside the nuclei of an atom.

If the strong nuclear force was stronger than it is, hydrogen would not form and nuclei essential for life would be unstable. If the strong nuclear force was weaker than it is, no elements other than hydrogen could exist. There would be no carbon, oxygen, nitrogen, sodium, potassium, iron or any of the other life essential elements. [See, Lee Strobel, Case for a Creator, pgs. 130-131 (2004) citing to discussions with Robin Collins, Ph.D.]

The strong nuclear force must be just-right for life to exist anywhere in the universe.

 

A Just-Right Weak Nuclear Force

The weak nuclear force is responsible for radioactive decay of elements like uranium, thorium and potassium. Without the weak nuclear force, stars (including the sun) would not burn at all.

If the weak nuclear force was stronger than it is, too much hydrogen would convert to helium which would cause stars, like the sun, to produce too much heavy element material.  If the weak nuclear force were any weaker than it is, too little helium would be produced and star burning would not produce enough heavy element material. It has been calculated that a change in the weak nuclear force by even one part in 10100 would have prevented the universe from being able to support life. [William Lane Craig, On Guard, pg. 109 (2010)]

The weak nuclear force must be just-right for life to exist anywhere in the universe.

All four fundamental forces of physics must not only exist and exert the just-right amount of force, but all four (4) forces must work perfectly together for life to be possible anywhere in the universe.  Even Stephen Hawking (one of the world’s most renown physicists) recognizes the extreme fine-tuning that exists in the system of physical laws that govern the universe:

The laws of nature form a system that is extremely fine-tuned, and very little in physical law can be altered without destroying the possibility of the development of life as we know it. Were it not for a series of startling coincidences in the precise details of physical law, it seems, humans and similar life-forms would never have come into being. [Stephen Hawking and Leonard Mlodinow, The Grand Design, pgs. 160-161 (2012)]

Conclusion

Only because the four fundamental forces operate within just-right parameters and work perfectly together is life possible in the universe. 

As referenced in this article and other articles on this website, the exquisite precision and chance calculations involved with the numerous finely-tuned design features necessary for life to exist in the universe are astronomical — numbers like 1060 (the mass density of the universe >>), 10100 (the weak nuclear force >>), 10120 (the energy density of the universe >>). 

The incomprehensibility of this kind of fine-tuning is more fully appreciated when one considers that there are only about 1025 grains of sand on all the beaches on Planet Earth. So, fine-tuning in the order of 1060 would be something like saying that not a single grain of sand could be added to or removed from one beach on Planet Earth without causing the earth to be unable to support life. Actually, the illustration is a tremendous understatement because it assumes a change in one part in about 1025 (the estimated number of grains of sand on Earth) whereas the total mass density of the universe must be fined-tuned to within one part in 1060 and dark energy must be fined tuned to 10120 which are substantially greater numbers that 1025.

When one looks at the probability calculations for life to have developed by chance, the numbers are even more incomprehensible.  For example, just the chance of amino acids randomly coming together to form the 2,000 enzymes that are essential for life has been calculated as only one chance in 1040,000 >>.

Taking all of the fine-tuned features that must exist in a life-permitting universe into consideration, Donald Page of Princeton’s Institute for Advanced Science has calculated that the odds of the universe developing by blind, random chance into a form suitable for life as one chance in 10,000,000,000124>>,  a number so large that it exceeds all imagination. [Ravi Zacharias, The End of Reason, pg. 35 (2008)]

As summed up by secular scientist, Fred Hoyle (a well-respected English astronomer primarily known for his contribution to the theory of stellar nucleosynthesis) —

A commonsense interpretation of the facts suggests that a super intellect has monkeyed with physics, as well as chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question. (Emphasis added). [Fred Hoyle, “The Universe: Past and Present Reflections,” Annual Review of Astronomy and Astrophysics 20, pg. 16 (1982)]

Consequently, Christian apologists maintain there is no compelling reason why belief in an intelligent designer (rather than random chance) is not a rational, if not the most rational, explanation for the existence of the universe and life in the universe, especially when one considers the multiple independent lines of argumentation for God’s existence including:

  • God’s existence best explains why anything exists rather than nothing (an argument for the existence of a “first uncaused cause”) >>
  • God’s existence best explains the cause of the universe coming into existence (the Kalam Cosmological Argument) >>
  • God’s existence best explains all the mind-boggling, just-right design features scientists have discovered throughout the universe which make it possible for life to exist in the universe (the Intelligent Design aka Teleological Argument) >>
  • God’s existence best explains the existence of objective morality
  • God’s existence best explains man’s search for, and innate belief in, meaning, purpose and significance
