It can look dumb, but I always had this question as a kid, what physical principles would prevent this?

as a software engineer that watches too much youtube, this is the first time it’s clicked for me:

If the train moves at the speed of light, then nothing inside it will move because time will stop.

the pieces of information:

  • time moves slower the faster you travel, and
  • nothing can travel faster than the speed of light

have never been concretely connected in my head, but this makes a lot of sense now: time moves slower (for you) the faster you travel BECAUSE that’s the thing that stops you from moving faster than the speed of light… AND that holds true from all perspectives because it’s like… a trade-off?
