two proofs that light does not exist

2. Nothing can travel faster than the speed of light, because this would be inconsistent with the observational fact that the speed of light must be constant for all observers. And, as we approach the speed of light, space contracts, so at the speed of light, space will have dwindled away to zero, since the speed of light is the absolute limit. If space did not approach zero, there might be another limit beyond the speed of light that could still be approached (if space were not zero at the speed of light, then at the speed of light space would still be contracting, and could potentially contract some more than it already had). Also if space did not approach zero at the speed of light, it would be possible to apply an acceleration that would affect the back of my body before the front, and this would create two distinguishable inertial frames of reference, which is impossible beyond the speed of light because the speed of light is (observationally) the absolute limit. If space is zero, then time must also be zero. Therefore at the speed of light, space and time are both zero. That is they cease to exist
