Multiverse: One Universe or Many? | World Science Festival

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 Original Program Date: June 1, 2013 MODERATOR: John Hockenberry PARTICIPANTS: Andreas Albrecht, Alan Guth, Andrei Linde, Neil Turok Multiverse: In the Beginning 00:00 John Hockenberry's Introduction 4:33 Participant Introductions 6:35 The Big Bang theory. 8:34 The vacuum of space and the Higgs field. 12:33 What is inflationary theory? 15:40 What does the inflationary model explain? 21:36 What is the experimental evidence of the multiverse? 26:22 What is so exciting about the Planck satellite?31:56 The CMB and what it means to a multiverse. 40:43 What came before the big bang? 46:45 Does string theory help predict there is a multiverse? 53:45 Having no choice is a hard choice to make. 1:00:33 Is the horizon of a black hole is much like the edge of the universe? 1:05:11 Is there a difference between a multiverse and two universes colliding? 1:11:23 Depending on infinity for predictions. 1:16:15 Don't miss a video!

ABOUT WORLD SCIENCE FESTIVAL: The World Science Festival (WSF) is a multimedia organization bringing the most transformative ideas in science to global audiences. Through long- and short-form videos spanning physics, cosmology, quantum mechanics, biology, neuroscience, consciousness, medicine, space exploration, the dilemma of free will, artificial intelligence, engineering, robotics, and beyond. WSF gathers world-renowned scientists, artists, and thinkers for dynamic discussions, debates, lectures, performances, films, and immersive live experiences. Founded in 2008 and headquartered in New York City, the World Science Festival is a production of the World Science Foundation, a 501(c)(3) nonprofit organization. Our mission is to cultivate a public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future. With live events reaching millions worldwide and hundreds of millions of digital views, WSF continues to expand its global impact through festivals, educational initiatives like World Science U, and digital content that explores the near and far future of our world.
