    1. What color is a mirror?
    2. If you were walking on water, what will happen if you trip?
    3. If you were driving a car at light speed, what will happen if you switch on the headlights?
    4. If you were choking on water, will drinking more water stop you from choking?
    5. Why do people keep saying space exists if its nothing?

    More as they come, stay tuned.

    lemme take a stab at some of these

    1)every color
    2)you would fall into/onto water, depending how its done
    3)you would be still the same speed but with headlights on
    4)drinking more would make it worse
    5)because even nothing is named, to show contrast to what something is

    If you talk about a mirror with exactly 100% reflectivity, it would have no color, however, suppose the mirror only reflected 80 % then there would be some light absorbed by the mirror and it would have its charactoristic color, say silver maybe or gold, or copper, depends on the composition of the mirror.

    If you tripped, you would fall on your face, presumable because you are walking on ice.

    Since you can't drive ANYTHING but photons at the speed of light, it is a meaningless question but if you are going something slightly less than C, the light coming off the lamp would be going at C so would leave the vacinity of the lamp but it would be doppler shifted to the blue, shorter wavelength.

    Yes, you would go from chocking to drowning.

    It is thought space is quantized so it is not nothing but little tiny bits of something that string theorists call strings, either open or closed and pegged to a dimension, kind of like velco sticking out of a piece of cloth.

    for # 3 you'd still see the headlights in normal color, since C is constant relative to the observer, aka you in this case.

    I agree with the rest... although it seems too easy and thus is probably wrong

    Same as if you were going at any other speed. Somehow the light will always get in front of you, even if you travel at light speed. Weird...it probably has something to do with the idea that time stops at light speed.
