Mixing Science and Religion: The Big Bang God

I’ve been reading about the origin of the universe again, looking at it from the scientific point of view. I have no problem accepting science’s theory that the universe began 13.7 billion years ago with an explosion. I’m amused that the Father of the Big Bang theory is a Catholic priest, Father George LeMaitre, who believed that Albert Einstein’s theory of relativity (1917) was not inconsistent with an ever-expanding universe. Einstein, however, believed that the world was a closed system, in perfect equilibrium and unchanging.

LeMaitre met Einstein at a conference on physics in October of 1927 and explained his conviction that application of  the theory of general relativity to the study of the cosmos would  in fact lead to the conclusion that the universe was dynamic, that it was moving. (A Russian mathematician, Alexander Friedmann, in 1922 had suggested the same idea but died before following up on his theory.)  Einstein’s response to LeMaitre was something like, “Father, your calculations are correct, but your physics is abominable.”

Undismayed by the senior scientist’s rejection of his theory, Lemaitre continued to look for  observable proof. About two years later LeMaitre had his proof. American astronomer Edwin Hubble published the results of data he collected by means of telescopic observations of the universe, and confirmed that most galaxies seem to be withdrawing from one another. The theory of an initial Big Bang as the origin of the universe seemed more than credible.

Years earlier Einstein had objected to physicists who proposed that the subatomic world depended not simply on determinable laws of mechanics (as those of Isaac Newton), but also on chance.  He said famously, “God does not play dice with the universe.” Einstein held out for a grand cohesive design and was dismissive of the notion that uncertainty was part of the key to exploring and understanding the world of science.

Tension between science and religion is less intense today than in past decades, but people of science and religion usually quell conflicts by happily acknowledging that science and religion are two different and separate fields in pursuit of the truth and the two should not interfere with each other. People of religion are less adamant about how God does things; chance may play a role and chance can be part of  God’s plan.

While I believe that God is ultimately responsible for creating ex nihilo (i.e., God did not use matter that pre-existed the Creator), I can accept the proposal that the Big Bang could have been the result of a new phase in a universe which had known many previous cycles of expansion and collapse.

In truth, however, my own conviction is that the Big Bang  was the explosion of God’s great love, the creative force which slowly evolved over billions of years to produce the universe as we know it today, and this explosion of love was charged with the purpose and intention of making creatures whom God would love so dearly. Yes, I’m mixing science and religion, but if both lead to truth, I have no hesitation to own the findings of both, and even allow some melding of the two into one philosophy of life.

The Bible tells who made the world; science gives me a clue about how it was made. I see no conflict between the two. The Bible is not a science book; a science book is not a book of religion. My eyes are not my ears; my ears are not my eyes, but both sets of organs help me come to knowledge.

The question that intrigues me is, “What would I know about God if I assumed the world was created by a divine being and yet science was the only way I had to draw conclusions about the creator. If I had no supernatural revelation in the form of Moses, prophets, Jesus the Christ, St. Paul and the Spirit-alive-in-the-Church what conclusions could I draw about the deity?”

Isolated from revelation, relying on science I could easily draw the conclusion that God (the creator) is complex, playful, patient, colorful, truly transcendent.

You my object that I have already brought religion into the answer by assuming there was a creator, but apart f the Bible and Church magisterium, I have to wrestle with the arguments the philosopher Thomas Aquinas offered on a natural plain for positing the existence of God. I cannot argue away the notion of an unmoved mover, or an uncaused cause. I do not need religion to come to acknowledge the existence of a creator-god. I think it a matter of common sense.

When I read that, based on supercomputer estimates, there may be 500 billion galaxies, I think how complex the creator must be.  When I read that the most distant object we know is a stellar explosion called a gamma ray burst which released as much energy as ten trillion Sun-like stars, I think how playful the creator must be.

When I read the universe has doubled in size eight times during the time it has taken for the light of the most distant celestial object to reach us, I think how patient this creator must be. When I read that scientists can deduce the chemical composition of the sun by collecting enough light to pass through a prism which then splits the light into a spectrum, I think how colorful the creator must be.

When I read this comment of Albert Einstein, “As a child, I received instruction both in the Bible and in the Talmud. I am a Jew but I am enthralled by the luminous figure of the Nazarene…No one can read the Gospels without feeling the actual presence of Jesus. His personality pulsates in every word. No myth is filled with such life,” I think how transcendent this God ours must truly be!

Thanks to revelation I can refine my understanding of God, without resolving the mystery, and feel pretty sure my assessment based on science is right.

Big Bang


I think it amusing and encouraging that a Belgian Catholic priest, Father George Lemaitre (1894-1966), is known as "the Father of the Big Bang." Inspired by Albert Einstein's general theory of relativity, Lemaitre proposed that if taken to its logical conclusion Einstein's theory demonstrated that ours is an ever-expanding universe.

Einstein, following the common opinion of his day, believed the universe was a closed system, that it was static. Lemaitre questioned the number (the so-called cosmological constant) which Einstein put into his theory to make it work. When Lemaitre proposed his theory to the master in 1927, Einstein reportedly replied, "Your calculations are correct, but your physics is abominable."

(To be fair, Alexander Friedmann, a Russian mathematician, using math rather than physics, had come to the same conclusion about five years before Lemaitre did, but died without ever following up with observational data. Lemaitre may be said to have re-discovered the theory of an expanding universe.)

Lemaitre's observational data was supplied in 1929 by the American astronomer Edwin Hubble, whose telescopic search of the galaxies verified that they indeed seemed to be receding from one another. Einstein finally agreed.

An unlikely "prophet" of the big bang theory was American poet and short-story writer Edgar Allen Poe (1809-49). In an essay he entitled Eureka (1848), Poe surveys the universe and develops his theory that the start of the universe came from "a certain exertion of the diffusive power (presumed to be the Divine Volition.)" This was 80 years before Lemaitre talked with Einstein.

The Big Bang implies that the universe had a beginning. The biblical story of Yahweh's creating the heavens and the earth had some scientific basis. The continuing expansion of the universe from that initial big bang showed that in a sense creation was still happening. There is a dynamic in the world as we know it, and evolution is an obvious possibility.

Dominican theologian St. Thomas Aquinas concluded in the 13th century that "that the world began is an article of faith...it cannot be proved demonstratively" (Summa, I, 46, 2). It seems most appropriate to me that a diocesan priest who studied Aquinas should be the one to offer a demonstration.

I am but a neophyte when it comes to following some of Aquinas' arguments. I could not explain Einstein's theory for love or money. I have only the vaguest sense of Lemaitre's discovery.

But I am thoroughly engaged by the idea that someone of Lemaitre's background in religion and Church ministry should propose this far-reaching discovery about the universe. Coming from a faith perspective I should expect the universe to be ever expanding. God has shown a super abundance of love, a prodigality of forgiveness, the sheer wastefulness of grace. The multiplicity of stars alone reflects the extravangance of his generosity. Lemaitre discovered through his study of science that the universe is still expanding. Perhaps he could have come to that same conclusion by reflecting on faith alone. Scientists would have balked at a conclusion based on religion, but the rest of us would have said, "Yes, of course the universe is dynamic! God is like that!"
