Neil deGrasse Tyson on Time: Doctor Who, Star Trek or Ray Bradbury?

What is time? In this Cosmic Query, astrophysicist Neil deGrasse Tyson answers a fan who wonders whether time is more like Ray Bradbury's linear depiction of time in "A Sound of Thunder," the branching timestream depicted in 2009's "Star Trek" or the way Doctor Who describes it in the classic episode "Blink": "a big ball of wibbly, wobbly, timey-wimey...stuff." Enjoy this "Behind the Scenes" video with comic co-host Colin Jost of Saturday Night Live Weekend Update.
