God and Astronomy – Robert Jastrow


Robert Jastrow (September 7, 1925—February 8, 2008) was an astronaut, physicist, and cosmologist who lived and worked in America. He was a head scientist at NASA, as well as a popular author and futurist.

He received his doctorate in theoretical physics from Columbia University in 1948, at the age of only twenty-three. He later joined NASA when it was founded in 1958. He was the first president of the Committee for the Exploration of the Moon, and at the same time, he was the director of the Theory Department at NASA (1958 – 1961). He was one of the founders of the Goddard Institute for Space Research in 1961, where he worked until his retirement in 1981.

He is the recipient of several medals: the NASA medal for outstanding scientific achievements, the medal of excellence from Columbia University, the honorary doctor of science from Manhattan College, etc. His views on creation were that although he was “an agnostic, not a believer”, in his opinion, “the veil over the mystery of creation will never be lifted by human effort, at least not in the near future.” He is the author of several books: “Red Giants and White Dwarf” (1961), “Astronomy: Basics and Limits” (1972), “Until the Sun Dies” (1977), “God and the Astronomers” (1978), “The Magic Loom”: The Mind in Space’ (1981), ‘Journey to the Stars: Today and Then’ (1990).

Religion and Science

"It is now clear that astronomical evidence supports the perspective of Holy Scripture about the beginning of the world. The details differ, but the essential elements of the astronomical explanation and that of Holy Scripture in the Book of Genesis are the same: the chain begins with man who arose suddenly and instantaneously, at a specific moment in time, in a flash of light and energy." - Robert Jastrow, astronaut, physicist, and cosmologist.


Now three lines of evidence—the motions of the galaxies, the laws of thermodynamics, and the life story of the stars—pointed to one conclusion; all indicated that the Universe had a beginning. A few scientists bit the bullet and dared to ask ”What came before the beginning? ” Edmund Whittaker, a British physicist, wrote a book on religion and the new astronomy called The Beginning and End of the World, in which he said, “There is no ground for supposing that matter and energy existed before and was suddenly galvanized into action. For what could distinguish that moment from all other moments in eternity?” Whittaker concluded, “It is simpler to postulate creation ex nihilo—Divine will constituting Nature from nothingness.” Some were even bolder, and asked “Who was the Prime Mover?” The British theorist, Edward Milne, wrote a mathematical treatise on relativity which concluded by saying, ”As to the first cause of the Universe, in the context of expansion, that is left for the reader to insert, but our picture is incomplete without Him.”

But the views of most physicists and astronomers are closer to that of Saint Augustine, who, asking himself what God was doing before he made Heaven and Earth, gave the reply, “He was creating Hell for people who asked questions like that.” In fact, some prominent scientists began to feel the same irritation over the expanding Universe that Einstein had expressed earlier. Eddington wrote in 193 1, “I have no axe to grind in this discussion,” but “the notion of a beginning is repugnant to me… I simply do not believe that the present order of things started off with a bang… the expanding Universe is preposterous… incredible… it leaves me cold,” The German chemist, Walter Nernst, wrote, “To deny the infinite duration of time would be to betray the very foundations of science.” More recently, Phillip Morrison of MIT said in a BBC film on cosmology, “I find it hard to accept the Big Bang theory; I would like to reject it.” And Allan Sandage of Palomar Observatory, who established the uniformity of the expansion of the Universe out to nearly ten billion light years, said, ‘It is such a strange conclusion, . . it cannot really be true.” (The italics are mine.)

There is a strange ring of feeling and emotion in these reactions. They come from the heart, whereas you would expect the judgments to come from the brain. Why?

I think part of the answer is that scientists cannot bear the thought of a natural phenomenon which cannot be explained, even with unlimited time and money. There is a kind of religion in science; it is the religion of a person who believes there is order and harmony in the Universe, and every event can be explained in a rational way as the product of some previous event; every effect must have its cause; there is no First Cause. Einstein wrote, “The scientist is possessed by the sense of universal causation.” This religious faith of the scientist is violated by the discovery that the world had a beginning under conditions in which the known laws of physics are not valid, and as a product of forces or circumstances, we cannot discover. When that happens, the scientist has lost control. If he really examined the implications, he would be traumatized. As usual, when faced with trauma, the mind reacts by ignoring the implications—in science, this is known as ”refusing to speculate”—or trivializing the origin of the world by calling it the Big Bang as if the Universe were a firecracker.


This is an exceedingly strange development, unexpected by all but the theologians. They have always accepted the word of the Bible: In the beginning, God created heaven and earth. To which St. Augustine added, “Who can understand this mystery or explain it to others? ” It is unexpected because science has had such extraordinary success in tracing the chain of cause and effect backward in time. We have been able to connect the appearance of man on this planet to the crossing of the threshold of life, the manufacture of the chemical ingredients of life within stars that have long since expired, the formation of those stars out of the primal mists, and the expansion and cooling of the parent cloud of gases out of the cosmic fireball.

Now we would like to pursue that inquiry further back in time, but the barrier to further progress seems insurmountable. It is not a matter of another year, another decade of work, another measurement, or another theory; at this moment it seems as though science will never be able to raise the curtain on the mystery of creation.


For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.
