Most quoted

"If the world has begun with a single quantum, the notions of space and time would not have any meaning at the beginning; they would only begin to have a sensible meaning when the original quantum had been divided into a sufficient number of quanta. If this suggestion is correct, the beginning of the world happened a little before the beginning of space and time."

— from Nature, 'The Beginning of the World from the Point of View of Quantum Theory', 1931

There is no conflict between science and religion. My science is my religion, and my religion is my science.

Various biographical accounts

The 'Big Bang' theory, as it is now known, is a rather crude name for what I envisioned. It sounds like a firecracker.

Attributed in discussions of his work

I am not a theologian, nor am I a philosopher. I am a physicist and a priest. The two are not mutually exclusive, though some seem to think so.

Biographical notes

If the universe had a beginning, it must have had a beginner. But that's a theological question, not a scientific one... for now.

Discussions on cosmology and faith

Einstein, bless his heart, initially found my idea 'abominable.' He later came around, which proves even great minds can be a bit slow.

Anecdotal accounts of his interactions with Einstein

Some scientists are so afraid of God that they would rather believe in an eternal, static universe than one that had a beginning. How quaint.

Attributed in discussions of scientific resistance to his theories

My theory is not a proof of God. It is simply a scientific explanation of the universe's origin. If one finds God in it, that is their own interpretation.

Interviews and writings

The universe is expanding, much like one's waistline after a good meal. But with far more profound implications.

Attributed in informal discussions

To say the universe is eternal is to say it has always been. A rather unscientific statement, wouldn't you agree?
