Episode notes

The Higgs boson was discovered at the Large Hadron Collider in 2012. It tells us something about how particle physics changed in the very early universe and gave us the sort of nice happy universe we have today. And so you can kind of chart out based on the masses of like the Higgs Boson where we lie in this landscape of stable universes or notstable universes.

Cosmologists are always talking excitedly about the Big Bang and all the cool stuff that happened in the 14 billion years between then and now. But what about the future? We don't know for sure, but we know enough about the laws of physics to sketch out several plausible scenarios for what the future of our universe will hold. Katie Mack is a cosmologist who is writing a book about the end of the universe. We talk about the possibilities of a Big Crunch (and potential Big Bounce), a gentle cooling off where the universe gradually grows silent, and of course the prospect of a dramatic phase transition, otherwise known as the "bubble of quantum death." Which would make a great name for a band, I think we can all agree.
