Ask anyone and they'll tell you that Neil deGrasse Tyson—astrophysicist, author, Cosmos host, and all around awesome guy—is one of the most iconic scientists of our time. So it was a dream come true when he stopped by VICELAND's Desus & Mero to give the hosts a crash course in topics ranging from time travel to the cosmos to how rainbows really work.
On Monday night's episode, Neil deGrasse Tyson also talked about what it was like to grow up in the Bronx, his infamous "actually" tweets, and his relationship with Bill Nye. Check out the digital extended cut above.
