Steven Steven's trick to sort of turn time into space is in a way exactly what the doctor ordered. He had an intuition that he could do all of physics without time, as actually everything could be just spatial, Euclidean geometries. Now almost 40 years on, really, from Steven's time into time goes into space business. And that's then and then we haven't even talked about holography. Right, we will. Don't you worry,. but I do want to go a flavor of some of the some of the issues that one faces here. You already mentioned turning time into something that looks like space. Yeah.

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.
