Pondering this mystery led Hawking to study the big bang origin, but his early work ran into a crisis when the maths predicted many big bangs producing a multiverse countless different universes, most of which would be far too bizarre to harbour life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked shoulder to shoulder for twenty years on a quantum theory of the big bang that could account for the universes lifefriendly character.
