# If your in a car traveling at the speed of light and turn your headlights on what happens?

Relevance

If you are going at the speed of light, which is the maximum speed of an object in C-Space. The photons you release will travel at the speed of light. So the photons will remain inside the headlamps. You will not be able to see anything.

Email me if you find out how to travel at the speed of light...it will be a great advancement in science.

If you were in the car, it would look the same as if you were standing still. Einsteins principle of relativity states that there is no way to determine if you are moving at a uniform velocity (without external reference). So the beam from the headlights moves away from you at the speed of light, no matter how fast you are going.

Dan A is correct. According to Einstein's theory, anything traveling at the speed of light *always* appears to the observer to be traveling at the speed of light, even if the observer is traveling in the same direction at the speed of light. This is, in fact, one of the fundamental principles *behind* the theory of relativity, as Michaelson & Morley discovered prior to Einstein's word that light traveled at the same speed in any direction (i.e. regardless of the direction the earth was spinning). Of course, they were looking for ether, and believed that they had made a mistake in their experimental design when they discovered less than the calculated difference in velocity.

The speed of light is constant... this is the principle behind relativity.

The light will still shine ahead of you at a speed of 3 x 10^8 m/s in YOUR relativistic frame.
