Ripples From The Big Bang: Listening to the Beginning of Time | World Science Festival

In March, a major breakthrough in understanding the origin of universe took the scientific community–and the general public–by storm. A team lead by astronomer John Kovac, using a powerful telescope at the South Pole, reported evidence of ripples in the fabric of space time produced by the big bang, a long-sought prediction of our most refined approach to cosmology, the inflationary theory. Amidst the worldwide celebration, though, some have been quietly suggesting that the champagne has been uncorked prematurely. Join a singular conversation, among the world’s most respected pioneers in cosmological theory and observation, that will explore the state of the art in the ongoing quest to understand the beginning of the universe. This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation. Original Program Date: May 30, 2014 Host: Brian Greene Participants: Andrei Linde, Alan Guth, Amber Miller, John Kovac, Paul Steinhardt Brian Greene's Introduction. 00:12 Participant Introductions. 20:34 Can we confirm that there are ripples in the fabric of space? 22:19 What did you find with BICEP2? 26:05 What is the inflationary theory? 31:46 What is making the universe accelerate? 37:33 What were the main issues with the inflationary theory? 44:42 What is chaotic inflation? 51:22 How do we calculate density motivations? 59:00 Looking for cosmic fluctuation. 1:03:40 How close were the predictions to the observations? 1:09:03 How confident are you that the swirls are coming from quantum fluctuations? 1:14:40 What are the concerns about the inflationary theory? 1:23:49 Final thoughts. 1:29:33 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.
