Neil deGrasse Tyson invites us into the future to the New York World’s Fair of 2039 in this exclusive season finale clip from Cosmos: Possible Worlds. Viewers visit the pavilion of the fourth dimension: time. Along with exploring a cosmic calendar, the question remains: if you could visit any moment in scientific history, where would you go? The finale episode of Cosmos airs on Monday, April 20 at 9/8c.
