if u wer going through space at the speed of light in ur car wat would happen wen u turned the headlights on?

Answer 1

If you could travel at the speed of light in a car and you turned on the headlights then the light from the headlights would leave the car at the speed of light. The speed of light is always a constant despite the frame of reference.

To develop this further if you imagine 2 cars travelling at 50mph towards each other. From the viewpoint of a passenger in 1 car it would seem that 1 car is stationary and the second is moving at 100mph.

This cannot be applied to light as it has its own set of laws. If two beams of light are heading towards each other, the realtive speed is still the speed of light, not double the speed of light.

Hope this helps.

Answer 2

OK, so you cannot travel at the speed of light but given enough energy you could travel at, say, half the speed of light.

So how fast will light travel away from your headlights then ... well, it will be just the same (300,000,000m/sec) if YOU measure it where YOU are, your speed relative to anything else is immaterial.

That's the funny thing about light, wherever you measure it it travels at the same speed RELATIVE TO YOU and those with you in the same 'frame of reference' (like on the same accelerating space-ship or planet or whatever)

Then just to confound all the above, the speed of light is constant only in a vacuum - in space - and slows down when it passes through materials of different density (that's how glass spectacles bend light to see clearly and things under water appear to be in the 'wrong' place). It is even possible to stop light photons completely using lasers and some special crystal (rubidium, I think) and then allow it to start up again when the lasers are turned off!

Answer 3

IF !! it were posible to travel at the speed of light ( this is still a debating point amongst the clever people) and you could turn your headlights on you would need something infront of you to reflect the light back, as space is reatively empty this is highly unlikely. You would probably see a rainbow effect this is because the spectrum is being broken down into its component parts which scientists believe travel at a slightly different speed, this is the Doppler effect, hope this has helped.

Answer 4

Let's say just under c to avoid that argument.

To the driver it looks as normal. To someone who sees the car moving at just under c, the light from the headlights moves at c but is narrow - like a laser beam - pointing in the direction the car travels. Oddly, perhaps, this is called the 'headlight effect'.

Answer 5

Well with our current knowledge in physics you cannot drive your car at the speed of light so your question is "invalid".

Why can't you drive a car at the speed of light? According to the theory of relativity, an object with a non-zero rest mass m will become infinite when travelling at speed of light. To bring it to that speed, you need an infinite amount of energy, which is not available in the whole universe....

Why, then, can light travel at the speed of ... light? Light (or a light photon) has zero rest mass, so it doesn't need infinte energy.

Now, what does a light see? (this is the proxy of your question - imagine you are a photon yourself). I can' imagine anything here, not having the experience myself. All I can say is to light, time is standing still, and the thing that "flows" continuously past it is ... space.

You see, we live in a world of something constantly flowing past us. If you stand still, time flows, and if you go very fast like light, then space flows...

Why doesn't time flow for light? It doesn't get old? Correct, it doesn't get old, nbot ever. Think of an explosion in a distant star. Light of that explosion takes years to reach the earth. When you see the explosion, it happened a long long time in your past... but what about the light photon that just fell into your eyes? It is still at the explosion time ... when it started the journey

Sorry if I confused you more...

Answer 6

The light of the headlights would come out and bend around the hood of your car, creating an auric glow around the bonnet... This is assuming you could travel at the speed of light, and assuming light speed travel didn't (contract) squash you and your motor vehical flat

Answer 7

If you were to move with a car at the speed of light ,your car would disintegrate in the form of radiation.
You would not have to worry about turning your lights on=you would become light radiation.
You need to study what is the nature of light and if you have the right teacher you might understand it.

Answer 8

First off, your lights would shine in front of you because they are in front of you. Secondly, you would have the appearance of being stretched out or what is known as Time Dilation. If some one was standing next to you you would appear to be longer then you are. Finally if you were traveling at the speed of light because you were entering a black hole, you would be stretched so thin - with your lights shinning in front of you - that eventually you would be ripped apart molecule by molecule. *hugs* ~:)

Answer 9

You would get a £60 speeding fine and most probably 3 penalty points on your licence for driving without due care and attention!

Answer 10

if you managed to reach the speed of light you will turn into energy and when you turn the headlights the frequancy of the wave (i mean you and your car) will increase.
