David Tennant Explains Einstein’s Theory of General Relativity In This Adorable Video

One hundred years ago, a guy named Albert came up with the most important physics-based theory of the century: the theory of general relativity. Even though physicists love this theory, which has been vital to pretty much every theory since, most of us normal denizens don’t really understand the theory. It involves things like “space time” and “warped time,” which are real things and not terms invented by Steven Moffat. For those of us who aren’t physicists, David Tennant is here to help. In this adorable animated video, the tenth Doctor uses his singular style of annunciation to explain Einstein’s theory in simple terms. In Tennant’s Scottish accent, “dark matter” almost sounds salacious.
