If you are traveling at the speed of light and turn your headlights on will they work?

Answer 1

Of course they'll work. The question is if you will see them. You can't travel at the speed of light, anyway, or physics is wrong, so nobody would be able to give you an answer.

Assuming you were just really close to the speed of light, you would still see them. Einstein discovered that the speed of light in a vacuum is constant to ALL observers, no matter how fast the source of light is going relative to the observer. So at any speed, you can see your headlights just fine.

Answer 2

Yes, unless you unplugged them, or unless you don't have enough battery power left from pushing the speed of light. :)

Try throwing a ball at your friend while you are standing still and then try throwing a ball at your friend while you are running towards your friend, and then try throwing a ball at your friend while you are running away from your friend - assuming your friend will catch all three and assuming that you are throwing with same force each time, another friend standing at the sideline will notice the difference in the speed. But to you, the ball will seem to travel away from you at the same speed only as long as the ball is accelerating away at the same speed as when you throw the ball as you are standing. WIll your friend standing on the sideline see the headlight shooting away from your car though?

Let's keep it simple. If it takes too many explanations, then it's not worth explaining and it's probably not correct nor do we fully understand it, however, we can always imagine, BUT test and verify when we can.

As far as Newtonian Velocity is concerned... We can not travel at the speed of light under "normal" conditions of the "known" and "accepted" physics at the moment, but there are other ideas in the unified field/unification theory that suggests otherwise. Remember, modern day physics was considered a blasphemy back when it was a new idea :o)

Answer 3

Relative newtonian velocities are somewhat meaningless at this speed FYI.

You cannot travel at the speed of light for 1. If you were traveling close to the speed of light, however, the headlights will work and you will see the light travel away from your car or spaceship or whatnot at the speed of light.

Answer 4

Yes, for the same reason a plane flying faster than the bullets it shoots (when the plane isn't moving), doesn't shoot itself.

Answer 5

course they will that too at double speed...havn`t heard of the concept of relative velocity?
