  1. Re:Length contraction? on Excursions at the Speed of Light · · Score: 1

    I'm pretty sure things only contract along the axis of motion. At least in STR. About cameras I have no idea.

  2. Re:Length contraction? on Excursions at the Speed of Light · · Score: 1

    All this sounds correct to me, though I don't know what "ray tracing" is. In any event, as several posters have noted, the whole idea of accurately representing what it would look like to travel at light speed is fraught with conceptual difficulties.

  3. Re:Length contraction? on Excursions at the Speed of Light · · Score: 1

    Just to clarify, do you mean: (a) The storefronts would not appear to be shorter as you go faster, though they would appear to be rotated, or (b) The storefronts would appear to be shorter as well as appearing to be rotated ?

  4. Length contraction? on Excursions at the Speed of Light · · Score: 2, Interesting

    I always understood that distances lying on lines parallel to your path (e.g. the length of a passing storefront) got shorter as you approached c. In the video it looks like the storefronts remain a constant length, or maybe even expand, as the speed increases. Am I missing something?
