Episode notes

Einstein's theory, where the description of reality in terms of space and time that we experience doesn't hold. inside black holes and at the big bang, my feeling is that in those extreme regions of the universe, the more fundamental holographic quantum nature rises to the forefront. And so the big bang in holographic way of thinking about the universe becomes almost like, it becomes almost like an epistemic horizon. A region where you call, yeah, you run out of bits almost literally. That's kind of where it stands.

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.
