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.


Which wave would travel fastest in a vacuum light or sound?

Light would travel faster in a vacuum compared to sound. Light travels at the speed of light in a vacuum, which is approximately 300,000 kilometers per second, while sound cannot travel in a vacuum as it requires a medium to propagate through, such as air, water, or solids.


Why did Einstein state that you can travel faster than light but not at the same speed at which the light travels?

Einstein's theory of relativity states that mass cannot accelerate to or past the speed of light because it would require infinite energy. However, objects with no mass, like light, can travel at the speed of light because they do not have the same limitations. Thus, according to Einstein, you can approach the speed of light but never reach or surpass it.


Why can't anything travel faster than light?

According to Einstein's theory of relativity, as an object with mass accelerates, its energy increases and its mass approaches infinity. This means that to accelerate an object with mass to the speed of light would require an infinite amount of energy, which is impossible. Therefore, nothing with mass can travel faster than light.


Why is it impossible to travel faster than light?

According to the theory of relativity proposed by Albert Einstein, it is impossible to travel faster than the speed of light because as an object approaches the speed of light, its mass increases infinitely and would require an infinite amount of energy to accelerate further. This means that it would take an infinite amount of energy to reach or exceed the speed of light, making it physically impossible to achieve.

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


Would you have a shadow if you go faster than the speed of light?

No, if you were able to travel faster than the speed of light, you would not have a shadow because light would not be able to keep up with your speed to create one. The theory of relativity states that nothing with mass can travel at or faster than the speed of light.

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.


What material would a light wave travel faster than through water?

Air.


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.


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.


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 a bulb travels at the speed of light and is turned on will it glow?

Light cannot travel faster than the speed of light, so a bulb traveling at the speed of light is not possible in the laws of physics as we know them. If it were somehow possible, the bulb may emit light, but we cannot definitively predict what would happen under such extreme conditions.


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".


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
