Episode 55 - Living in a Black Hole

Send us Fan MailWhat if our universe isn't just expanding into space, but exists entirely inside a black hole? This isn't fringe speculation. Physicists Lee Smolin and Nikodem Poplawski have published peer-reviewed work suggesting every black hole spawns a new universe, and the math reflecting our own observable cosmos back at us is hard to ignore. In this episode, we break down the real science behind black hole cosmology, from the Schwarzschild radius calculation that mirrors the size of our universe, to the holographic principle that suggests everything we experience is encoded on a two-dimensional boundary surface. We then take that foundation somewhere the physics papers won't go: if our universe was engineered inside a black hole, simulation theory stops being about computers and starts being about spacetime itself. And if black holes are nested universes all the way down, and all the way up, what does that architecture tell us about where we sit in the structure? Support the show
