if u are moving at the speed of light can u see or if u are moving at the speed of sound can u hear?

Answer 1

Everybody keeps forgetting the reason why the Theory of Relativity has the word "RELATIVITY" on it.
As you approach the speed of light, "your" time (relative to somebody who is stationary) slows down. To you, it looks as if every minute is normal, but to somebody stationary looking at you, it seems as if your clock is going slower.
Therefore,
When you approach the speed of light, everything would seem normal to you. You would still see and hear.

Answer 2

While gkltdd is correct, if you ignore that and make the assumption that this can be done in a regular vehicle in normal space/time (non-wormhole), then the answer is yes and no.

If were to travel at the speed of light, you would be able to see and hear from in front of you. However, anything to the 90degree's and behind you would not be visible or audible as you would be traveling as fast (for light) or faster (for sound) that the waves being emitted.

Answer 3

No one can move at the speed of light. Einstine theroized what might happen if we could, but its only a theory and we won't know for sure till we can. So the point is moot.

Answer 4

I think liam assumes you "could" travel at the speed of light, in wichy case who says you could not see?
If you travel at the speed of sound you can still hear, you'll hear of the toher folks that are travelling at the speed of sound in your plane, their voice travels relatively to you. you wont hear some shouting from outside the plane though.

Answer 5

--gkltdd that equation is wrong

if you are moving at the speed of light it is

E=mc^2/ sqrt (1-v^2/c^2)

Answer 6

No, because you would be a ball of energy.

Einstein:
E=mc^2

NOTE/EDIT:
What I meant was E= m (rel) c^2. Common sense Mantis....

The answer is still that you would be transformed into a ball of energy. (for all of the thumbs down.)

Answer 7

yes
