Episode notes

Holographic constructions work very much what we call top-down, so backwards in time. They're anchored on the histories that play a role in the wave function or anchors on our observations. I think it's more the Feynman kind of description that is perhaps at the heart of this theory. Do you believe there really exist other universes where things are very different? Other branches? That does not quite enter in our theory.

Is there a multiverse, and if so, how should we think of ourselves within it? In many modern cosmological models, the universe includes more than one realm, with possibly different laws of physics, and these realms may or may not include intelligent observers. There is a longstanding puzzle about how, in such a scenario, we should calculate what we, as presumably intelligent observers ourselves, should expect to see. Today's guest, Thomas Hertog, is a physicist and longstanding collaborator of Stephen Hawking. They worked together (often with James Hartle) to address these questions, and the work is still ongoing.
