CORRECTIONS:
- Yes, the diagram of the photon clock on the train has a light path of over 45° from the vertical which means the train is going faster than the speed of light. Let’s just agree the train (and everything within it) is not to scale!
- Let me know if you spot any more mistakes!

Clips from Interstellar (2014) are all copyright some combination of Paramount Pictures and Warner Bros. and I thought we could all agree my use here is pretty fair. But they have already put a copyright claim in on this video, so theres that.
