PONDERING THE IMPONDERABLES: The Biggest Questions of Cosmology

Saturday, June 3, 2017
2:00 pm - 3:30 pm EST

Physicists and cosmologists are closing in on how the universe operates at its very core. But even with powerful telescopes and particle accelerators pushed nearly to their limits, experimenters struggle to keep up as theoreticians march forward, leaving grand theories untested. Is our universe unique or one of many? What was there before the Big Bang? Why is there something rather than nothing? Some argue that if these deep questions can’t be confirmed empirically, they’re not relevant to science. Are they right? Join world-leading cosmologists, philosophers and physicists as they tackle the profound questions of existence.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Andrei LindeCosmologist

Andrei Linde is a professor of physics at Stanford University, one of the authors of the inflationary theory and the theory of inflationary multiverse. He invented the theory of chaotic inflation, which is the most general version of inflationary cosmology. Linde also helped to develop the theory of eternal chaotic inflation, and the mechanism of vacuum stabilization in string theory.
