Tyler J. Tyler says, how might time travel be policed or regulated if it were able to happen? If we could all... If you have bad actors going through it, right? Right. Well, again, I'm less fearful of time travel because of the view that I hold that you couldn't actually change anything. Brian: Is that the same thing as Hawking's time travel conjecture? You think? It depends exactly which one.
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?
