PBS Space Time - Season 2015 Episode 25 Can You Trust Your Eyes in Spacetime?
10.0048 minutes
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!
