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!

Past Episodes On SpaceTime:
“Are Space And Time An Illusion?”:

“Is Gravity An Illusion?”

“Can A Circle Be A Straight Line?”
