    I know your all going to say, "This is a stupid question and you can't move faster than light." But, if you were to achieve FTL travel, would you go blind because your mover faster past the light so it can never reach your eyes. Like how when your near something that smells but you get away to fast for it to reach you. (On an unrelated topic, How fast is the speed of smell?)

    Yes it is a stupid question and you can't go faster than light.

    Since you already knew the answer it is all the more stupid.

    Moreover, the speed of light is the same for all observers in all inertial reference frames so your analysis, with FTL replaced by an achieveable speed doesn't work either.

    If you were to travel faster than the speed of light, you wouldn't be there, there is no there, no where, and there is no you.

    I answered this on a similar thread


    you wouldn't go blind, just mostly blind. the faster you go, the less you see, (think tunnel vision), at lightspeed you would see maybe 120 degrees, as you go even faster it will shrink more. eventually all you can see is what is directly in front of your eyes.


    the reason being, light 3 feet to one side has to move 3 feet to reach you, at lightspeed, by the time it's moved 3 feet, you're in front of that light, light in front doesn't have that problem, light 3 feet in front of you by the time it travels 2 feet it will hit you because you've moved forwards.
    It's not how many questions you ask, but the answers you get - Booms

    This is the Acadamy of Science! we don't need to 'prove' anything!

    wrong

    But there are some illusions that occur due to relativistic optical effects. For instance spheres that are ovoids due to length contraction in the direction of motion look like spheres.
