Why Did The Universe Begin?
Summary
Hosts Jana Levin and Steve Strogatz interview physicist Thomas Hertog about his collaborative work with Stephen Hawking on the universe's origins. They discuss moving beyond the multiverse theory to a "Darwinian" model where physical laws evolved from quantum uncertainty. Using holographic principles, they argue that time and laws emerged retrospectively, suggesting fundamental limits to what we can know about the Big Bang.
