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!
Thanks to my Patreons who mean I can film hours of myself talking about relativity and then ask Alex to edit that into something which makes sense. Here is a random subset of those fine Patreon People:

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.
