Science & Environment How Did A Mistake Unlock One Of Space's Mysteries? By NPR/TED Staff Published February 15, 2013 at 5:42 PM EST Facebook Twitter LinkedIn Email Listen • 12:29
Part 1 ofTED Radio Hour episode Peering Into Space .
Physicist Brian Greene explains how the prevailing theories about the fabric of space changed dramatically in the last century — twice. The most recent shift in thinking came about from a
strange mistake, and revealed hidden truths about the nature of our universe. Later in this episode, Greene talks more about why this discovery hints at the existence of other universes.
About Brian Greene
Brian Greene is perhaps the best-known proponent of superstring theory, the idea that minuscule strands of energy vibrating in a higher dimensional space-time create every particle and force
in the universe. Greene, a professor of physics and mathematics at Columbia University, has focused on unified theories for more than 25 years, and has written several best-selling and
non-technical books on the subject including The Elegant Universe, a Pulitzer finalist, and The Fabric of the Cosmos—each of which has been adapted into a NOVA mini-series. His latest book,
The Hidden Reality, explores the possibility that our universe is not the only universe.
