David Tennant Explained Einstein’s Theory of General Relativity for Its 100th Anniversary

A century ago, a 36-year-old Albert Einstein published his general theory of relativity, which to the average Joe entails fuzzy concepts like spacetime and field equations and free-falling bodies. Now, though, animator Eoin Duffy and a team of writers have made this charming video explainer, which, while not especially erudite, gets the basic tenets of the theory across while still managing to entertain.

Part of that entertainment comes from narrator David Tennant, erstwhile Doctor Who, who now spends his time controlling minds and wearing purple on Jessica Jones. Enjoy.
