  1. "That happens (of course) in neither frame" What does happen then
  2. Einsteins relativistic train in tunnel paradox. There is a video on YouTube with this title. Towards the end of the video one person sees the length contracted train fall into the gap. The person on the train seems to see it become like a fluid that flows into the gap*. How can the train behave like this * i gather that this because the train is not completely rigid
  3. Thanks heres the video
  4. Simultaneity - Albert einstein and the theory of relativity. This video says that the person on the train will see lightning from front of the train first. But what if we take it that the train is stationary and the earth is moving below the train. How could we tben explain the passenger on the train seeing the front bolt first
