Many of the world’s most eminent physicists were among the audience of two thousand to whom Georges Lemaître was about to present a theory that bordered on the crackpot.

Lemaître was not just a physicist and a mathematician, but a Catholic priest as well, and he was to speak in a session on a topic that physicists had just begun to grapple with: the evolution of the universe. Dressed in his black clerical garb and white collar, as if prepared to take confessions, he stepped to the podium and presented an idea that veered perilously close to theology.
