Steven Moffat (and 3 scientists) explain Doctor Who's time travel

The beloved BBC sci-fi series Doctor Who has always been a little timey-wimey when it comes to how the actual science of time travel works, but apparently quite a bit of thought actually goes into making the TARDIS run. Want to see Who showrunner Steven Moffat and some scientists explain how it all works?

This enlightening discussion comes to us thanks to a recent BBC special dubbed The Science of Doctor Who, which brought in theoretical physicists Michio Kaku and Jim Al Khalili, as well as space scientist Maggie Aderin Pocock, to chat with Moffat about time travel concepts.

The discussion is actually pretty interesting, and they touch on just how close (or far away) we actually are to making all of this a reality. But more than anything, it's absolutely awesome to see real physicists and rocket scientists talking about Doctor Who as if it were actually real.

Just awesome.

Check out a clip from the show below.

What do you think? How close are we to building our own little blue boxes that are bigger on the inside?
