If you could travel faster than light, then you could also travel to the past. This is related to the definition of simultaneity, in the Special Theory of Relativity.

Would light travel faster through space or wind?
It would travel faster through space since there are no particles to get in its way. The wind is an opposing force so it is harder to move faster. The difference between the two would be negligble but specifically, light moves faster through space.
What can you say about the speed of the different colors light in air?
I could say that shorter wavelengths move faster, but that would be wrong. The truth is that all wavelengths/colors travel at the same speed.
Which wave of light has the greatest frequency?
nope. because then it would travel faster than light, which is currently impossible.
Why do light waves require a medium in which to travel?
Light waves do not require a medium through which to travel. They will travel (propagate) perfectly well in a vacuum. Otherwise, light would not pass through the vacuum of space. It would be very dark here on earth as the light from the sun, moon and stars could not reach Earth through the vacuum of space.
Can a bullet travel faster than the speed of sound?
Yes, bullets travel faster than the speed of sound. That is why if someone was to shoot a target from a distance and you were standing beside the target, you would be able to see the target get hit by the bullet before you would hear the crack of the gun Some bullets travel faster than the speed of sound, but not all.
What happens if you could travel at the speed of light or faster?
you would never get old, but you wouldn't be able to see yourself

Can a lepton travel faster than the speed of light?
Leptons have mass.According to special relativity, no particle with mass can travel at or faster than the speed of light. It would take infinite energy to do so.
Will humans be able to travel faster than light in the future?
That seems unlikely. Any method used to travel faster than the speed of light would also make it possible to travel to the past; and as any science-fiction fan knows, that is quite problematic.
What material would a light wave travel faster than through water?
Air.
Could we travel faster than the speed of light Why or why not?
No. Just to travel AT the speed of light would require more energy than the entire universe contains. So all objects move at some fraction of light speed, never 1 nor greater.
The speed of light is faster in a liquid true or false?
It travels faster in a liquid than in a gas, but it would travel faster still in a solid.
If you could travel speeds greater then the speed of light would you be able to travel back in time?
Yes and No. Yes because traveling faster than light would make you go back in time. No because you would need an infinite amount of energy to go at the speed of light according to Einstein Also going at the speed of light or faster you would tern into light. So "you" could not go at the speed of light but light could. Time travel is possible but only at the earths gravitational pull (Turn) if the earth went backwards in spinning, but at the speed of light, the earth would move backwards through time as it broke the atmospheric compression field. WELL, AS IT HAPPENS... On a Distance against Time graph, the more distance you travel in the same amount of time, the steeper the line and therefore the faster your speed. The speed of light on such a graph is VERY steep, but it is NOT vertical. If it was a vertical line, then you would be travelling INFINITELY far distances in zero seconds. Which is impossible. However, assuming that it isn't, going EVEN FASTER would mean the line would start to curve back on itself, which would mean you were travelling a certain distance in a certain number of NEGATIVE seconds. Which would mean you were travelling back in time. So to answer your question, going faster than the speed of light would result in a VERY high speed. However, to go back in time you would need to go faster than a vertical line on a distance against time graph. In other words, to go back in time you would need to go FASTER THAN AN INFINITE SPEED. So, no you couldn't travel back in time by going faster than the speed of light. Even if you could, which you can't.
If there is a speed of light what is the speed of dark?
Dark does not exist, it is only the absence of light. Darkness is not an entity, so it does not travel and has no speed. In principle, a shadow or nonentity could "travel" faster than the speed of light. For example, if you pivoted a powerful laser a few degrees the point of light would travel across a screen very far away at a "speed" greater than light. Note that this is not at all faster than light motion. You could achieve a similar effect by casting shadows on things very far away. But none of this is actually a "speed."
Why do light waves travel faster in empty air than in matter?
I believe it might be because the light has nothing to reflect off of so it would travel in a straight line
Would man ever coceivably travel faster than the speed of light?
No. Anything EXCEPT for light that travels as fast or faster than light would need a near infinite amount of energy, and I expect that near all of us know that near infinite energy is and was only available when the universe was compacted to smaller-than-atom size, as it contained all the energy that's ever existed. Even if we did manage to travel at or faster than light-speed, we would travel back in time. That means the faster than light we travel, the farther back in time we would go. Knowing that, so far, we know for a fact that faster-than-light travel has not been achieved, as we would've had impacts on this time period. Some believe that the pyramids were built by alien's, but I believe that we were the ones who built it, but us from the future. Does this answer your question?
IS electromagnetic waves travel faster than speed of light?
Electromagnetic waves are, by definition, light. So they travel at the exact same speed as light.Also, a "Do" would be appropriate here, instead of an "IS".
