Katie Mack on How the Universe Ends | Perimeter Institute Public Lecture

The Big Bang theory tells the story of the beginning of the Universe, our cosmic home for the last 13.8 billion years. But how does the story end? I’ll share what modern astrophysics tells us about the ultimate fate of the cosmos, and what the catastrophic destruction of all reality would look like to anyone still around to see it. Dr. Katie Mack is a theoretical astrophysicist exploring a range of questions in cosmology, the study of the universe from beginning to end. She currently holds the position of Hawking Chair in Cosmology and Science Communication at the Perimeter Institute for Theoretical Physics, where she carries out research on dark matter and the early universe and works to make physics more accessible to the general public. She is the author of the book "The End of Everything (Astrophysically Speaking)" and has written for a number of popular publications, such as the New York Times, Washington Post, Scientific American, Slate, Sky & Telescope, BBC Science Focus, and Cosmos magazine.
