Existence of God – Astrophysics
In The Beginning…
Evidence for the âBig Bangâ
Originally, Albert Einstein believed, like most scientists of his day, that the universe was infinite into the past, without a beginning. What changed his mind?
Today, some people believe God created everything as recently as 6,000 years ago. Others think that blind chance explains why our universe is capable of supporting life. What are they missing?
The answer in both cases is recent scientific discoveries. Specifically, evidence of a beginning. And evidence that strongly supports creation by an intelligent being or, at a minimum, shows it to be nearly impossible for the universe to be an accident.
Letâs start with Einstein. To make his General Theory of Relativity (GTR) work, he had to add a âfudge-factorâ called the cosmological constant. This allowed the GTR to account for our universe being eternally static into the past. Then he met Fr. Georges LemaĂźtre.
In 1927, Fr. LemaĂźtre had put forth his theory that the universe was not static but was, in fact, expanding. While Einstein appreciated the elegant math involved, he didnât accept the idea of an expanding universe because of the far-reaching implications. Einstein recognized that an expanding universe would require a beginning.
In 1933, Einstein and LemaĂźtre traveled together to California for a series of seminars. While there, Edwin Hubble convinced Einstein that LemaĂźtre was correct â the universe is, in fact, expanding. Hubble had come to the same conclusion as LemaĂźtre from a different scientific approach. He was able to show Einstein, with the help of the Mount Wilson Observatory telescope, the âred shiftâ. This red shift proved that all observable galaxies in the universe are traveling away from our galaxy. In fact, the farther a galaxy is from our galaxy, the faster it is traveling away from us. Einstein had to correct his GTR by removing the cosmological constant and factoring in LemaĂźtreâs math.
What was the consequence of this discovery? LemaĂźtre reasoned that the universe had to have a beginning. An absolute beginning of the universe signifies a beginning of physical time. Since physical time conditions all physical reality (that is, physical reality does not exist without physical time), the absolute beginning of physical time must also be the absolute beginning of physical reality. Prior to the absolute beginning of physical reality, physical reality would have been nothing – utterly nonexistent.
This ânothingâ could not have done anything. It could not have moved itself from nothing to something. As the ancient Greek philosophers have taught us for thousands of years, âFrom nothing, only nothing comes.â Then how did physical reality come to exist? It must be that something beyond (transcending) physical reality did it, and this âtranscendent somethingâ is called a Creator.
Letâs look at some evidence for the âBig Bangâ as the creation event. In 1948, scientists Alpher, Herman and Garnow, as part of their work on Big Bang Nucleosynthesis, predicted that the universe should show remnants of the Big Bang in the form of Cosmic Microwave Background radiation. In 1965, Arno Penzias and Robert Wilson observed CMB radiation by pure accident while scanning the heavens with an antenna to map signals from the Milky Way. (For this accident, Penzias and Wilson shared a Nobel Prize in 1978. )
CMB radiation was later confirmed by two COBE satellites, the WMAP satellite and the Planck satellite, which all show this radiation to be uniformly distributed throughout the universe and at a temperature of 2.7Â degrees Kelvin, as predicted. The temperature allows scientists to date the Big Bang back to 13.8 billion years ago. âLet there be light …â
Actually, the first light didnât appear for maybe 200 million years after the Big Bang. There is a NASA article explaining the initial light and the âred shiftâ mentioned above – search for âFirst Light & Reionizationâ at jwst.nasa.gov
So, we have seen evidence for a beginning of the universe from:
1) Georges LemaĂźtreâs math
2) Hubbleâs âred shiftâ
3) CMB radiation.
Additional proof can be found in the Borde-VilenkinGuth Proof and other Space-Time Geometry Proofs (evaluating multiverses, bouncing universes etc. â they all require a beginning).

Evidence of Fine Tuning…
Universal Constants and Entropy
Letâs now look at universal constants and their associated anthropic coincidences. Universal constants are literally the mathematical specifications for our universe. They are the same everywhere within our universe â not just our galaxy. Anthropic coincidences are those universal constants whose values are exactly what is required for life to exist, even though the odds are highly unlikely at best. There are about 20 universal constants. Here are a few examples:
Entropy (2nd law of thermodynamics â a measure of disorder. Technically, entropy is not a universal constant, but it is a recognized and measurable, statistical inevitability.)
Speed of Light (~186,000 m/s or ~300,000 k/s)
Gravitational Attraction Constant (G = 6.67 x 10-11)
Weak Force Constant (gw x 1.43 x 10-62)
Strong Nuclear Force Coupling Constant (gs=15)
Electromagnetic Force has three associated constants:
a) Mass of a proton (mp = 1.67 X10-27 kg)
b) Mass of an electron (me = 9.11 x 10-31 kg)
c) Electromagnetic Charge (e + 1.6 x 10-19 C)
What is the likelihood that, at the Big Bang, these constants had just the right values for life to develop and continue to exist (i.e., the anthropic values)? Letâs consider Entropy, the law of disorder, before we get to the universal constants. Entropy increases when a wind-up toy runs down. The spring inside the toy gets tight with the winding of a key and it seeks to get back to its normal state by unwinding. Once maximum disorder is attained (unwound spring), no further work can be done, the toy stops working unless someone winds it again. Same with our universe. Stars are working to heat space to a uniform temperature but they will likely burn out in the distant future. With no outside source for additional fuel, stars will be unable to do any work, like an unwound toy. We will be at a high entropy state, unable to generate or sustain life.
Scientist Roger Penrose calculated the odds of Entropy being low enough, at the Big Bang, for life to form at 1010123 to 1 against. DNA evidence is admissible in court to find a person guilty âbeyond a reasonable doubtâ since the odds against error are 42 billion to one. The odds against Entropy being low enough at the Big Bang to allow life to form in our universe are vastly higher – trillions of trillions of trillions to one. Is it more reasonable to conclude that the Entropy level is the result of chance or the work of an intelligent Creator fine tuning the universe?
Letâs look at some universal constants. If either the Gravitational Constant or the Weak Force constant had varied from their values by one part in 1050 (.00000000 0000000000000000000000000000000000000000001) â either higher or lower, the universe would have continuously exploded in its expansion, incinerating everything (bad for life forms) or contracted into a black hole compressing everything into a very, very tiny mass, 10-33 centimeters (equally bad for life forms). Is this another âanthropic coincidence?â
If the Strong Nuclear Force coupling constant had been 2% higher at the Big Bang, there would be no hydrogen in our universe (no nuclear fuel for stars, no water, etc. â quite bad for life forms). Conversely, if the SNF coupling constant had been 2% lower at the Big Bang, there would be no element heavier than hydrogen (no carbon – disastrous for life.)
Finally, if the Gravitational Force, the Mass of the Proton, the Mass of the Electron, or the Electromagnetic Charge had varied ever so slightly (higher or lower) from their values at the Big Bang, then the entire universe would have been populated by blue giant stars or red dwarf stars. Blue giants incinerate everything and red dwarfs do not give off enough heat to get anything in the universe beyond freezing. Potential life forms would have either burned up or frozen. Yes, more âanthropic coincidencesâ.
What are we saying? At the Big Bang, the very smallest of shifts â higher or lower â in the values cited above would have made the emergence of any life forms impossible! And not just the above constants, but a lot of the others as well! What were the odds of hitting the anthropic values (the values needed for life forms) of all our universeâs constants so precisely at the Big Bang when the possibilities either higher or lower were virtually endless? They were roughly equivalent to the odds of a single monkey typing the entire corpus of English literature by the random tapping of keys in a single try. Or someone winning the lottery a trillion times in a row. It is enough to make non-believers believe. The famous physicist and cosmologist Sir Fred Hoyle, of Cambridge University, was an atheist who, when confronted with the necessity of these âanthropic coincidencesâ working in concert with one another to produce carbon at the Big Bang, stated, âWould you not say to yourself, âSome super-calculating intellect must have designed the properties of the carbon atom, otherwise ]the chance of my finding such an atom through the blind forces of nature would be utterly miniscule?â Of course you would… A common sense interpretation of the facts suggests that a super intellect has monkeyed with physics, as well as with 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.â (Fred Hoyle 1981. âThe Universe: Past and Present Reflections.â Engineering and Science. Pasadena, CA: California Institute of Technology Press, November, pp. 8-12.)
Later on, he compared the odds of the universe having abundant carbon (a necessary building block for life) to a tornado blowing through a junkyard and leaving in its wake a fully assembled jumbo jet all ready for flight. Needless to say, Hoyle changed his mind about atheism, and now believes in an intelligent Creator.
The evidence of a Creator is all around us. Weâve examined astrophysics alone. More evidence can be found through philosophy, medicine, and biology.
Father Robert J.Spitzer, S.J., Ph.D., (philosopher of science, author of 10 books, and Magis Center founder) has stated, âIf the values of the constants did not occur by pure chance (because that is virtually impossible) and those values are necessary for life forms, then there must be another cause â either a multiverse or a supernatural designer.â He explains that multiverses (for which we have no observable evidence) also need a Creator. They require a beginning and even more fine tuning.
As Fr. Spitzer asks, âIs it reasonable and responsible to believe in a Creator if there is no other natural explanation for the constants of our universe being what they are?â
