What Existed Before Time Itself?

Our Spotify podcast: https://open.spotify.com/show/5rqQFYd... Almost everyone who learns that the universe began about fourteen billion years ago eventually asks the same quiet question: what was there before? It feels like the most natural thing in the world to wonder. But our best theory of the beginning does not actually describe the beginning — pushed back toward the very first instant, the equations dissolve into infinity, the place where physics admits it has reached the edge of its own validity. And the closer you look, the stranger the question becomes, until you start to suspect that the word before may not point anywhere at all. So what if time itself had a first moment, or no first moment, and asking what came earlier is like asking what lies north of the North Pole? This is a slow, late-night walk to the very edge of time, as close as physics can take us. We sit with a fourth-century bishop who decided there was no "then" when there was no time, with a philosopher who proved that time both must and cannot have begun, and with the physicists who watched time round off into space, who wrote down an equation for the whole universe and found no time inside it at all, and who traced the one-way flow of time back to a fingerprint left at the beginning. We follow the no-boundary proposal, imaginary time, the problem of time, and the strange possibility that there was no edge at all. By the end, the question is not so much answered as transformed. Get cozy and let this slow walk to the edge of time keep you company tonight.
