Filling the Big Gap in Einstein’s Theory | Paul Steinhardt | TEDxCLESalon

Paul Steinhardt is a theoretical physicist whose research spans cosmology, astrophysics, particle physics, condensed matter physics, geophysics and photonics. Paul Steinhardt is a theoretical physicist whose research spans cosmology, astrophysics, particle physics, condensed matter physics, geophysics and photonics. He is one of the architects of inflationary cosmology, a modification of the big bang theory that proposes to explain the large scale structure of the universe. He also the first to demonstrated phenomenon known as eternal inflation, an unintended consequence of inflation and quantum physics that leads to a multiverse, instead of the smooth and flat universe that inflation was supposed to create. This led him to become a skeptic and to develop competing alternatives, such as the cyclic theory of the universe, in which the big bang is replaced by a big bounce. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
