A recent BBC America special, entitled The Science of Doctor Who, sought to explore exactly that, various scientific elements of the long running sci-fi adventure. Experts in various fields got together to pick apart the science, figure out how realistic it is, and see how close science and science fiction actually are in this case.
In the clip below, show runner Steven Moffat is joined by theoretical physicists Jim Al Khalil and Michio Kaku, and space scientist Maggie Aderin Pocock, to talk about the time travel in Doctor Who. They offer various possible explanations for the Doctor’s ability to tumble through time in the TARDIS, as well as attempt to lay a theoretical foundation for time travel in general.
The thing that struck me most about this video, aside from scientific concepts that I don’t particularly understand, is how stoked all of these people are. Sure, they’re talking about their life’s work, their great passion in this world, in a wide public forum. That has to feel good. But they also come across really excited to talk about Doctor Who as well. Scientists who are way into science fiction might be the nerdiest thing to ever exist, but it’s cute as hell.
