  1. You would not be able to see the headlights because the speed of the car is identical to the speed of the headlights.

    More important, if you are driving at the speed of light, you are very likely to get into a car accident.

    If you are lucky enough not to get into an accident, the cops will definitely give you a ticket for speeding.


  2. first of all it is impossible to move with the speed of light because when we accelerate something with the speed of light its mass increases to infinite mass and to move infinite mass infinite force is required which does not exist.....and if you move with that speed and you turn on the lights of your car than it will come out as you see ordinary nothing different will be happened..

    hope you understand it..

  3. if your goin at the speed of light n u turn lights on then u wont see anything cause since ur moving at the same speed u would just be goint along with it

  4. your lights wuld come on...

    um the light wuldnt travel infront bcause it wouldnt have time to catch up

  5. Strangely enough, you'd see it as you do now. Let's say the speed of light is 100 mph. If you go 99 mph, the light will still zoom ahead as if you were standing still. If that phenomenon happens at 99, it is a good possibility that it will be the same for 100.

  6. If you are driving at the speed of light and you turn some headlights on?

    First scenario, you are traveling at the speed of light...and the light emission from the headlights will travel at 2x the speed of light. (from a static reference point)

    The second scenario is if the light particles are the only source of propulsion (provided it becomes a propulsion technology) then the turning on of lights (provided it provides the same output of luminous flux emissions) it should cancel the propulsion out.

  7. The theory of relativity holds that the speed of light is observed to be the same for all observers regardless of their inertial reference frame.  This means that no matter how fast you are going, light will always seem to zoom past you at what seems to you to be the speed of light.  The solution to this strange paradox is time dilation.  If you are travelling at .99C, time is going very very slow for you.  So while a stationary observer may see you going past very quickly, and the light only moving ahead of you a little bit faster, since time is slowed down so much for you, you will observe the light to be travelling at its regular speed.  What you actually see is a more complicated question, because everything will be very highly blue-shifted, but I don't think that was part of your question anyway.

    Oh sorry I forgot, as your speed increases so does your time dilation, up to the speed of light.  At the speed of light, your local time is, theoretically, completely stopped.  What end results this would have are debatable at best.  Travelling at the speed of light kind of "breaks the equation" sort of in the same sense that the singularity at the center of a black hole does.  Keep in mind that it would take an infinite amount of energy to accelerate even a single particle to the speed of light, so this is no more than a thought experiment anyway.

  8. if you are driving at the speed of light and turn on the headlights you would see nothing. Light projected is equal to the speed of light.

  9. If you are at the moving at the speed of light you wouldnt be able to see anything

  10. Nothing. Until you stop.
