We’re thrilled to welcome cosmologist and author Katie Mack to our livestream series! Respected cosmologist, writer and author Katie will be taking part in Uplink 07 this Friday, May 1st at 3PM EDT / 8PM BST / 9pm CEST. You can watch live on our YouTube channel right here! Don’t forget to subscribe to our channel for news on some very exciting forthcoming Uplink livestreams.


Dr Katie Mack is a theoretical astrophysicist who studies a range of questions in cosmology, the study of the universe from beginning to end. She currently holds the position of Assistant Professor of Physics at North Carolina State University, where she is also a member of the Leadership in Public Science Cluster. Throughout her career, Katie has studied dark matter, the early universe, galaxy formation, black holes, cosmic strings, and the ultimate fate of the cosmos. Alongside her academic research, she is an active science communicator and has been published in a number of popular publications such as Scientific American, Slate, Sky & Telescope,, and Cosmos Magazine, where she is a columnist. You can find her on Twitter as @AstroKatie.


Katie is publishing her first book The End Of Everything (Astrophysically Speaking) this August! It’s an accessible and eye-opening look at five ways the universe could end – and the mind-blowing lessons each scenario reveals about the most important concepts in cosmology!


We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now? Katie has been contemplating these questions since she was a young student, when her astronomy professor informed her the universe could end at any moment, in an instant. This revelation set her on the path toward theoretical astrophysics. She takes us on a mind-bending tour through five of the cosmos’s possible finales: the Big Crunch, Heat Death, the Big Rip, Vacuum Decay (the one that could happen at any moment!), and the Bounce. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, the book is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know!
