Ptolemy Tompkins, collaborator on the New York Times bestselling Proof of Heaven and Proof of Angels, is at his lowest point, personally and professionally, when he meets with an astrophysicist with a message for the world: God is real, and science proves it.

Proof of God is the unlikely story of how this serious scientist and this broken writer, in a series of conversations stretching over several months, come to understand that the universe--from the smallest sub-atomic particles that make up everything in existence to the farthest reaches of the universe--bears evidence of a creator. In short, God not only exists, but science gives us tools to know this.

Proof of God shows how science and religion both point to the same stunning and world-changing truth: God is real.
