Katie Mack unravels the connections between the smallest particles, the largest interstellar objects and the various ways the universe might end.

Why you should listen

Theoretical cosmologist, scientific storyteller and TED Fellow Katie Mack tackles the biggest and most profound questions about our universe. What is it made of? How did it begin? How will it end? In her work as a physics professor at North Carolina State University, she aims to create links between the wealth of new data astronomers and physicists are gathering and the latest developments in new theories of the cosmos. Parallel to her academic work, she uses her skills as a writer and communicator to make physics and astronomy more accessible to everyone through science writing, social media and public speaking. Her book, The End of Everything (Astrophysically Speaking), explores how the universe might end.
