Why you should listen

Katie Mack tackles the biggest questions about our universe: What is it made of? How did it begin? How will it end? As the Hawking Chair in Cosmology and Science Communication at the Perimeter Institute for Theoretical Physics, she researches dark matter and the early universe. Beyond academics, she shares the wonders of physics and astronomy through science writing, social media and public speaking. Her book, The End of Everything (Astrophysically Speaking), explores how the universe might end, weaving together scientific theory with profound questions about existence. She is a TED Fellow.
