Imagine knowing that a discovery you've made will bring you a Nobel Prize … only to suddenly learn that it was based on an error. In 2014, Brian Keating, a professor at the Center for Astrophysics and Space Sciences at the University of California, San Diego, led a team that reported finding one of cosmology's most treasured secrets: proof of the theory of cosmic inflation.

Keating talked to host Steven Strogatz about why he chases the universe's greatest mysteries and what it was like to have a major discovery slip out of his grasp.
