That's amazing. I've watched lots of videos about length contraction and I don't think any of them ever mentioned this (the shape of an object moving a near light speed won't change to an observer, it will just appear as if it had rotated instead of being "squeezed" as every video about this seems to imply)!

- MayeulC 3y agoYou rather showed the opposite. While interesting, this video only explains length contraction, not the Terrell–Penrose effect. In this video, the passing spaceship would appear to be rotated to the observer, not just contracted, as, to quote Penrose via Wikipedia, the light from the trailing part reaches the observer from behind the [spaceship], which it can do since the [spaceship] is continuously moving out of its way"
