If you were traveling in a vehicle at the speed of light, and you turned ur lights on, would anything happen?

The the car would stall

Ha\n\nInteresting speculation \n\n1. The light will not change color no matter how fast you go. Only in your perception it will, so unless the law enforcement is traveling within your frame of reference you would be found guilty anyway.\n2. True, if you are moving towards the light its frequency will increase towards the blue and will appear green to you, but the acceleration would kill you.  \n3. If you could travel with speed of light why would you care about traffic lights?\n\nGood question anyway.

No it can't.\n\nLaser light goes at exactly the speed of light.

Moving faster than light isn't really the real issue for space travel as traveling AT the speed of light solves all the distance problems(unless you are interested in time travel!). Of course that in itself is a big challenge. If one could demass the vehicle then surely one could achieve the speed of light!!! Afterall photons do travel at this speed.\nBut we would do very well even with speeds like .99999c because time dilation will reduce the time required drastically. Have the science, just need the technology!

nope... it would have a delay.  I would guesstimate that it would take about 30-45 seconds for the light to come on.   I am just guessing here.

This is where The Theory Of Relativity starts to come in to play. Relative to your position in the car traveling at the speed of light, the headlights come on and illuminate your path. Relative to someone outside the car watching you travel the speed of light, nothing happens, no light travels outward past the headlamps.

No matter how fast you go or think you are going, light always appears to be going the speed of light.\n\nEven if you are going 0.99999999999 c from the viewpoint of an outside observer, you would still see light traveling at the speed of light around you. Now, light sent by objects moving at 0.9999999999 c towards you (those "ahead" of you) would be severely blue-shifted and light from objects moving away from you at that speed (those "behind" you) would be severely red-shifted.\n\nBut light from any object moving the same speed as you would look perfectly normal. In fact if you covered the windows of your spaceship (it better be a spaceship, since you won't be in any atmosphere for very long), you wouldn't know you were moving at all!

The moment you hit the speed of light, time would stop for you, so it would be pretty hard (impossible) to turn the darn lights on!\n\nSaid another way, as you approach the speed of light, the outside observer sees you slowing down; when you hit the speed of light, it would take the observer an infinite amount of time to see any change in your state.\n\nNow, suppose you left your headlights on the whole way, what would everyone see?\n\nAs you approached the speed of light, the light is still reflecting off the objects around you, so the observer, and you, continue to see the reflected light. Once you hit light speed, however, the energy transfer required to turn heat into light wouldn't occur, so no one would see the photons. Of course, since you're traveling at the speed of light at that point, everyone would see you hit the object.\n\nOr this way... the light leaving your headlight changes it's frequency in proportion to the speed you're moving, once you hit light speed, the light would become matter! Of course, the wave packet that is light + your car wouldn't are too much, since time wouldn't exist for you anymore.\n\nHave a nice trip!

You can't be in a vehicle going the speed of light, because as objects accelerate they gain mass and a car going the speed of light would be insanely massive.

well, its absolutely impossible to travel at the speed of light, but lets pretend you can so i can actually give you an answer to the question. The speed of light is actually the ultimate speed limit to the universe, nothing can travel faster than light, so although you would expect the light to be going at twice the speed of light (you plus the speed of light, because of einsteins theory of relativity)it can't because it is physically impossible for even light to travel faster than the speed of light so it would be going at the same speed of you and not reach any path in front of you. Of course, if you turned on your headlights before you started moving, the light would always be one step ahead of you.\n\nbut again, this situation couldn't happen anyway since you can't get to the speed of light, it would make the denomonator in the lorentz factor 0, and you cant have a 0 in the denomonator of a fraction.

Interesting quatum phenomenon question.  The lights would come on, but they might appear strange to an observer due to the Doppler effect.  You, inside the car, would continue to see a headlight 'beam' because light's speed is a universal constant and not dependent on the speed of the source.  However, traveling beyond the speed of light in conventional space is not possible, to our knowledge.  For one, it would require infinate energy.  It would also cause macro-scale collapses in casaulity (effects happening before the cause).  To date, these bizzare effects have only been seen on quantum scales.

This is one of the oldest questions in the world, after Einstein came out with his special relativity.  The answer is that no matter how fast you are going, your headlight beam is STILL shining ahead at the speed of light. This is exactly what the equations say, and it works.  If it wasn't true, then all the giant particle smashers in the world costing billions of dollars wouldn't even work.

If you are travelling fast I would think the signal would be completely disrupted...:D

I'd say you disappear, and as soon as you're gone, your mother reappears. And if you keep doing it, you'll create an endless loop.\n\n\nGot another one for ya:\n\nYou're in your spaceship, traveling at the speed of light. You turn on the headlights. What happens?

The two key elements in this question are that the speed of the spacecraft is constant, and that you are at rest relative to the spacecraft.  In this situation, you will observe the beam of light moving forward and hitting the object just the same as if you were sitting in your living room.  This is in accordance with Einstein's Special Theory of Relativity.\n\nHowever, if the spacecraft were accelerating instead of moving at a constant speed, the same might not be true. As long as the spacecraft continues to accelerate, even at speeds below the speed of light, it is possible to set up a scenario in which the spaceship stays ahead of the beam of light forever!  This is in accordance with Einstein's General Theory of Relativity, which considers the effects of acceleration and gravity on light.

This question comes up very regularly. If you do a search you will find it has been answered dozens of times in the past few months.\n\nThe speed of light is an absolute constant. It doesn't matter what speed you are travelling at the light will always be travelling away from you at the same speed: the speed of light.\n\nThe freaky part is that the light from your headlights would seem to be travelling away form you at the speed of light (C), but to an observer who was sitting still the light would also appears to be travelling away from them at the speed of light. How can that happen? Well it's one of the tricky bits of relativity, but part of the solution lies in understanding that although light never slows down or speeds up relative to any observer it does change frequency.\n\nSo to you the light from your headlights will look quite normal, but to someone sitting still your headlights will appear to be emitting x-rays. The light would be invisible to them.\n\nThe corrolary of that is that any light approaching your windshield will be equally shifted into the x-ray part of the spectrum. Although the headlights will be emitting visible light, any time they strike an object and reflect back they will reflect back extremely low frequency light that is invisible to the human eye.\n\n\nSo no, it won't do a damn bit o good to turn on your headlights. That's not because the light won't travel, it will travel just fine. The problem will be that any light that reflects back off the road will be invisible to the human eye.

No it is not possible to travel faster than light because the equipment you try to use will not work. The fastest thing to probably work may be a fast car. But there is still no way to travel fater than the speed of light. Speed of light travels at about 7 miles per second. I hope this helps.
