What Happens After The Last Star Dies?
Our Spotify podcast: https://open.spotify.com/show/5rqQFYd... The stars are temporary. Every one of them, including the small yellow one that rises over you each morning, belongs to a brief opening chapter of cosmic history, and the sky full of them that you treat as the permanent backdrop of the world is closer to a single frame in a film that runs almost forever. The age of starlight ends at around one hundred trillion years, and against the darkness that follows it, the entire era of stars rounds down to almost nothing. So what actually happens after the last star burns out, when the universe can no longer make light, and how much of all of time still lies ahead in the dark? Tonight we take the long, slow walk forward through the far future of the universe, era by era, following the timeline that astrophysicists Fred Adams and Gregory Laughlin call the five ages of the cosmos. We move through the death of the last star and the age of embers, past cooling white dwarfs and diamond-cored black dwarfs, through the slow unraveling of the galaxies and the possible decay of matter itself, into the long reign of black holes evaporating across a googol years, out to the last unwitnessed supernovae and the near-perfect stillness of heat death. And we sit with the newest ideas about how it all ends, from black dwarf supernovae to the surprising possibility that even the corpses, and even you, slowly evaporate. Get cozy and let this slow walk through the far future of the universe keep you company tonight.
