Before the Big Bang V

Summary In this film Stephen Hawking, James Hartle and Thomas Hertog explain their model of the early universe: The No Boundary Proposal. In the 1960's and 70's Hawking and Penrose showed that according to classical general relativity, given some minimal assumptions the origin of an expanding universe is a singularity: a point of infinite density and spacetime curvature. But this and other singularity theorems do not take into account the strange world of quantum mechanics. So in the 1980's Hawking and collaborators started to build a model of the big bang that included quantum effects.The result is the No Boundary Proposal, a model that may be able to explain some of the deepest mysteries of the cosmos such as, is there a multiverse? how is there an arrow of time and what really happened a the big bang? This is the fifth in a series of films exploring competing models of the early universe. View more details
