Multiverse: One Universe or Many?

Full Program: Big Ideas Programs | 01:22:35

Featuring Theoretical Cosmologist Andreas Albrecht, Cosmologist Alan Guth, Cosmologist Andrei Linde, and Physicist Neil Turok with Journalist John Hockenberry Moderating

The inflationary theory of cosmology, an enduring theory about our universe and how it was formed, explains that just after the Big Bang, the universe went through a period of rapid expansion. This theory has been critical to understanding what’s going on in the cosmos today. But now, this long-held notion—which seems to suggest as-yet-unproven and perhaps unprovable features such as the multiverse—is under increasing attack. Through informed debate among architects of the inflationary theory and its prime competitors, this program explored our best attempts to understand where we came from. This program is part of the Big Ideas series.

The multiverse is not some exciting possibility suggested by the theory of inflation. It's a contrivance designed to save that theory. Without a multiverse, inflation doesn't work: so, presto chango! If you really want inflation to work you just gotta go with the multiverse. Garbage in, garbage out.
