20150819: Do Events Inside Black Holes Happen?
 04:56: ... determines the spacetime geometry in its neighborhood, the resulting geodesics of which correspond to ...
 05:19: So as far as Earth is concerned, that black hole generates the same spacetime geometry out here that the Sun does.
 06:26: See, spacetime geometry in this region is very foreign.


20150715: Can You Trust Your Eyes in Spacetime?
 00:02: But before we can graduate to the curves version and general relativity, we need a stronger foundation in spacetime geometry.
 01:07: Now, we're not going to do a complete treatment of special relativity or all aspects of flat spacetime geometry.
 01:22: Our principle tool for exploring flat spacetime geometry will be something called a spacetime diagram for representing physical events.


20150708: Curvature Demonstrated + Comments
 06:29: I wanted to make sure this was on better footing before we moved on to flat spacetime geometry in the next episode.


20150702: Can a Circle Be a Straight Line?
 07:49: Flat spacetime geometry is part two, which is next week.
