When we look at the stars in the night sky, it’s easy to wonder about our personal significance to a universe so vast. Brian Greene, professor of physics and mathematics and director of Columbia University’s Center for Theoretical Physics, joins host Krys Boyd to talk about the many ways we contemplate our existence. His book is called “Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe.”
