What would happen if you were in a car traveling the speed of light and you turned on your head lights?

Well, nobody can say for sure.
First, mass increases as speed increase, so you'd never actually get going that fast.Or, for really fast speed, the faster you go, the harder it is to go faster.
But, the most likely answer is: Your headlights would turn on, you wouldn't notice anything different.
As you get close to the speed of light, an effect called 'foreshortening' kicks in. You think you are looking 100 miles ahead, everyone else see you looking an inch ahead. In other words, when you get going fast enough everything _around_ you gets 'squished in'.
So, to you it would look like the light traveled just as far, and just as fast as usual, but everyone else would just see a doppler shifted greenish blob of light.

Speed of light changes with reference for example if the speed of light = 3.8*10^8 m/s and your going 10^8 m/s then you see the speed of light moves 4.8*10^9 m/s in reference to you therefore theoretically if you were moving the speed of light the light around you would be move 2*3.8*10^8m/s and the headlights would apear normal.

you won't be able to pass on the speed of sunshine. issues that accomplish that pass in uncomplicated terms at that %, in no way speedier and in no way slower. if you're going at almost the speed of sunshine, and also you turn on the headlights and degree the speed of the mild that comes out from them, you'll examine a similar % of sunshine that you'll examine in case you and the motorized vehicle were status nevertheless. a lot of human beings do not forget that transferring at some % relative to the observer (hence the "idea of Relativity") motives variations in the mover's length, time, and mass. (The equations that describe the variations are stated as the Lorentz differences.) "%" is, inspite of each thing, length in line with time. As you move in route of the speed of sunshine, the variations on your length and time exercising consultation in this way of way that the size-in line with-time of the mild from the headlights comes out to be a similar fee of length-in line with-time because the sitting-nevertheless fee is. so that you'll degree a similar % of sunshine from those headlights at any % you've been going.

It s a very good question dat would seem to chalenge d theory of relativity.but d fact s dat d assumptions taken by einstine while proving d theory was 'd speed of light is absolute n we take everything relative to dat. So d speed of light does nt change with d change in frame of referance.dat means
when u r standing on d ground or moving in a train dat moves some hundred km or ur hypothetical assumption

since you are travelling at speed of light, you can see light in front of you......Source(s): common sense
