Episode notes

Jim Kelly: How does a hypothetical paradox preclude the existence of time travel? Brian O'Neill: Information is this intangible thing. And I always hear physicists arguing about whether we lose or gain information every time you do something with a black hole. So it's really concrete when you think about it as information carried by stuff.

What type of time travel is in A Christmas Carol? Neil deGrasse Tyson and comedian Chuck Nice answer fan questions on time travel, paradoxes, and wormholes with theoretical physicist, Brian Greene. Did Ebenezer Scrooge get pulled through a wormhole?
