The Earth is not round (but it’s not flat either)

So what is the true shape of our planet? And if it’s not perfectly spherical, could there be anything else in the Universe that is? Watch the one-minute animation above to find out.

This animation is based on an episode from BBC Radio 4’s series The Curious Cases of Rutherford and Fry. Listen to A Study In Spheres, an exploration of roundness.
