Your in a car travelling the speed of light, and you turn on the headlights. What happens?

It's physically impossible to achieve the speed of light. When any object approaches the speed of light, everything inside and outside the object slows down, mother nature does not let any object reach the speed of light. So the car couldn't get to the speed of light in the first place.

The Truth
Another reason why the car could not reach the speed of light is because when you reach the speed of light, you need to have an infinite mass, which the car cannot do.

Einstein's Theory of Relativity; any object with mass cannot travel at or above the speed of light.

So the answer is, your car cannot get to the speed of light.

If in some magical world you could travel at the speed of light , The light of the headlights wouldn't turn on.

You guys are no fun. Fionn is the only fun one.
But fionn, I turned them on.

Your question contradicts Einstein's Special Theory of Relativity which states that no object with mass CAN travel at, or above, the speed of light (c). As your car approaches c, its resistance to acceleration (mass) increases so that it would take an impossibly infinite force to actually reach c. Your question, then, is based on an impossible premise. It's like asking 'What would happen if I reached the North Pole and kept going north?'

As you approach the speed of light with your headlights on, however, you would still measure the light beam racing away from your car at 186,000 miles per second (c). A 'stationary' observer watching this happen, though, would not then measure the beam's speed at almost twice c. Relativity says that all observers always get the same measurement for c.

While that may not sound logical or plausible, it happens because what we normally think of as fixed concepts--length and time--are both variable at high speeds. If you observed a car travelling past you at close to c, its length in the direction of travel would appear shortened and the passage of time on board would appear slowed down.

Why in the hell would you need headlights traveling at the speed of light...

If, for sake of argument, you got going that fast, anything close enough to bounce light back to u making you able to see it would be in your path and would cause you to hit it.

Okay nerds, he's saying if the car DOES reach the speed of light. He's saying will it? Have some fun!

The car could never reach the speed of light.
