Think like a physicist. Wonder like a human. Into the Impossible is where Cosmic Conversations happen â uniting Nobel Prize winners, iconoclasts, authors, and technologists to explore realityâs deepest questions. From AI to aliens, from biophysics to the brain, from the cosmos to the multiverse, Brian Keating, Chancellorâs Distinguished Professor of Physics at UC San Diego covers it all.
If youâve ever asked Whatâs out there? or Whatâs next?, this is where curiosity meets clarity.

In a sweeping conversation drawn from his collaboration with Stephen Hawking, Thomas Hertog explores the radical âno-boundaryâ theoryâa vision of the cosmos with no singular beginning, evolving laws of physics, and a past that isnât fixed until observed. Rejecting the untestable multiverse, Hertog and Hawking built a fully quantum cosmology that embeds the observer within the equations, predicting inflation and replacing anthropic guesswork with a falsifiable framework.
Hertog explains how time could emerge from something deeper than the Big Bang, why constants of nature may be dynamic, and how holography hints the laws of physics themselves might fade away at the origin. He then turns to the experimentsâfrom next-generation CMB polarization to gravitational wave backgroundsâthat could confirm or refute this bold vision, challenging us to see the universe as a living, evolving system whose history we help to shape.
