Can You Trust Your Eyes in Spacetime? (2015x25)

Air date: Jul 15, 2015

Last time we talked about what curvature means, looked at geodesics, great circles on spheres, and tried to understand the notion of "straightness". This week on Spacetime, we take a detour into how geometry works in spacetime. Get excited, because this episode is even more mind-bending than the last!
