If you were in a car traveling at the speed of light, and then turned your headlights on what would happen?

Answer 1

interesting

Answer 2

The light they were emitting would also be traveling at the speed of light; like it would even if you weren't traveling at the speed of light?

Now, your implied question might be: Would they help you see; would they illuminate anything. Maybe, but it wouldn't matter. You can 'outrun' your lights going 200 mph let alone the speed of light; the car cannot stop fast enough if you see something in the headlights that would make you stop.

Of course, if you designed a car that went the speed of light, then:
1. There'd be no where you could drive it safely (unless you invented a mechanism to auto-steer, stop, etc. so that you wouldn't hit anything), and
2. You'd probably be rich (as light speed travel could be applied to things other than cars).

Answer 3

A car couldn't, unless it was invisible to the eye, and then the headlight would be at the same speed, so you wouldn't know the difference. In otherwords, speed is speed, whether it is a car, or planet, or light beam or a light beam. Speed is the same. Kind of like traveling on earth, with a motorcycle, or bicycle. Things go slower than the speed of light, but they go the speed you are going. Does light chase you? No. Only the earth moves, and depending on the direction you are going does it seem faster or slower.

Answer 4

All cars are cars travelling at the speed of light. So, when you turned your headlamps on, they would come on, and they would light up the road so you could drive better. Everything travels at the speed of light, just in different directions through spacetime. If you are talking about a car travelling at the speed of light relative to the road, I'm gonna guess there is some kind of explosion and a plasma trail. But in general, when you are in a car and you turn on the headlamps, they come on. From your point of view the light from the headlamps travels away from you at the speed of light. From the point of view of an observer watching you recede from them at the speed of light, you are flattened, along with the beams from your headlamps, to an infinitesimal size in the direction you are travelling, and time is dilated, that is, you do not age (and thus light has no time to move) in transit in a reference frame through which you are travelling at the speed of light, which everything is doing, only in slightly different directions. That's kinda why nothing ever changes. It's all moving much too quickly.

Answer 5

If you were travelling in a car at the speed of light, you would be a pile of volcanic ash. The wind resistance would have created such enormous friction that before you got halfway to the speed of light, you would have spontaneously combusted into carbon dioxide and water.

Realistically, I highly doubt there is a car or corporeal human body that could survive travelling at the speed of light for much more than a nanosecond.

Answer 6

If you were traveling at the speed of light, you would traveling the same speed of light so the light wouldn't be a head of you but be with you. So you really couldn't really see anything in front of you. It would actually be dark in front of you

Answer 7

You'd be driving in the dark! The lights wouldn't project forward because you're travelling that fast.

Answer 8

whilst glancing down at the headlight switch, you would have travelled several thousand miles, and probably crashed cos you werent paying attention !

Answer 9

as u r moving by the seed of the light.... i guess u wont be able to see any thing abut the light

Answer 10

Uh, gee Tennessee, what would happen? Maybe we should ask Mr. Whoopee!!!!

Answer 11

you would turn into a black hole and we would not have to answer another question that doesn't have a reasonable answer, you listen to too many comedians.
