Multiverse: One Universe or Many?
- Published on: 07 August 2014
- 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 World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
