If you're in a vehicle going the speed of light, what happens when you turn on the headlights?

Answer 1

At that speed, I'd be more worried about the brakes.

OK, seriously - the headlights would shine normally from your perspective. From the Earth's frame of reference, they would take forever (literally!) to turn on, but since you would be traveling at the speed of light, "forever" would appear as normal time to you (a quirk of the theory of relativity), so you wouldn't notice any difference from if you were stationary. The headlights would work just fine as far as you were concerned.

In case you're worried about the light moving forward when you're already going at the speed of light, that isn't a problem. As Einstein discovered, physical laws follow your frame of reference, so the light would (from your perspective) still appear to move at the speed of light forward away from your car.

This ignores the inconvenient fact that it's impossible for you to reach the speed of light, but if you could somehow do it, the above answer is what you would see - headlights working normally.

Answer 2

you wouldn't be able to see it infront of you b/c Light does not inhibit speed of moving objects
for example if you had a train moving 30 mph and on that train an rc car moving 4mph the total speed of that vehicle would be 34 mph b/c of the train moving underneath it on the other hand if you have a lamp on top of that train the light waves would still travelat the speed of light without being influenced by the speed of the train

this concludes that the speed of the vehicle would not influnce the light coming from the headlinghts but since they are traveleing at the same speed none of the light would result in illuminating the road or whatever it is infront of you.

And anyways your eyes and brain cannot see and process things that fast.

Answer 3

while you're interior the vehicle, you nonetheless see the sunshine going from the headlight on the cost of sunshine as commonplace. while you're on the floor (table certain) you purely see the sunshine in no way comes out. It sounds contradictory. Does the sunshine ever comes out form the headlight? that is because of the fact time interior the vehicle remains table certain with admire to the individuals on the floor. So if time remains table certain, easy does not flow regardless of if it strikes a the cost of sunshine.

Answer 4

I think, from an observer who is standing outside, motionless, he'll probably see no lights since it can't leave your headlight...

not sure though from your point of view. maybe you'll see the lights, since in relative to your vehicle, you're not moving anywhere.

Answer 5

I think it's similar to breaking the sound barrier when you go faster than the speed of sound, only in this case you break the light barrier which creates a photonic boom.

Answer 6

Its impossible to go the speed of light because as you approach that speed the mass of the car imcreases which would make you go slower.

Answer 7

You're car emits a glowing white aura, as the light surrounds you...

Answer 8

Since I spend most of my time on the roads in reverse or sideways, I go faster!

Answer 9

i would assume that the light would trail behind you...but i suppose there is no way to tell! Interesting question!

Answer 10

saying you hadnt fried yet you would actually not see them everything would be a white blurr
