Meanwhile, in the trenches of the western front, a devoutly religious young Belgian Georges Lemaitre vows to become both a physicist and a Catholic priest if he survives. When the war ends, Einstein does make his breakthrough and is thrust into the international limelight. Lemaitre confronts him with a startling concept: that buried in the maths of the theory of relativity is a beginning of space and time, a moment when the universe came into existence - a day without yesterday. But can the priest be trusted? Or is he simply trying to foist a version of Biblical Genesis onto Einstein's now world famous theory.
