So long, in fact, that humankind will almost certainly be long-extinct by the time the last star fizzles out. I had the pleasure of meeting Mack when she joined me and my co-host Sara Geidlinger to record an episode of our “Bonn Park” podcast.ĭuring our fascinating conversation with Mack, she explained a number of the possible scenarios that cosmologists predicted for the very end of the universe, such as slow heat death, or sudden vacuum decay.Īll the possibilities for the death of the universe, she reassured us, are a long, long, long way in the future. That may sound like a grim tour, but I had the most wonderful guide: Katie Mack, who is known to her many fans on social media as is a theoretical cosmologist and author of the 2020 popular science book “The End of Everything (Astrophysically Speaking).”Īnd starting this June, she is joining the Perimeter Institute for Theoretical Physics in Waterloo, where she will research the mysteries of the cosmos and contribute to Perimeter’s work in public outreach and science education. I was recently given a guided tour of the end of the universe.
