What happens if you're traveling at the speed of light and you turn a flashlight on...?
This is the quintessential Relativity question, not really a mind blowing speed of light question. If you are witnessing the traveler zooming by you at the speed of light and they turn on their flashlight, the light does not escape the end flash light due the fact that nothing moves faster than the speed of light. Even a light of a flashlight that is turned on cannot go faster than the speed of light. It's the Law!
Here is the Relativity part. When the traveler himself, turns on the flashlight the light itself behaves just as it would normally. The light shines forward at the speed of light ahead of the vehicle. This occurs because the flashlight is stationary relative to the traveler. It is going zero miles per hour relative to the traveler. It's all relative. Different results but true to the laws of physics, Relative to the Observer. You cannot observe from outside of the vehicle and also observe from inside the vehicle at the same time so you see no paradox.
This is not how it appears. It is how it is. That is what Relativity is all about
Jeez, you've never watched Star Trek?? The light will behave relative to the vehicle, just like Bordz60 said. It's all theoretical, though. Nothing with mass can achieve the speed of light.
Then you'll not be able to see where you're going :-)
But what happens if you turn around and turn the flashlight on. Do you see in to the past?

If you're in a car which is on the speed of light, what happens when you turn on the headlights?

It is proven that time stops when you are moving at the speed of light. Time as we know it on earth is a man made notion, for it is really a measurement of distance - a revolution around once. Therefore it would be relative to where you were and how fast you are moving and not at all a...

If I was on a space ship traveling at the speed of light (The natural speed limit proposed by Einstein) and I fired a gun would the bullet remain in the gun?My belief is no it would not. I believe the bullet would leave the gun at the same increased velocity that it would achieve if I had fired the...

if it happens then just move in universe, today in ploto and the other day in other galaxy.

What is the speed of dark?My husband found this question in his fortune cookie tonight. Neither one of us knew how to answer it. And we certainly didn't know how it related to fortune. So, I thought it might be interesting to throw it out here and see others had to say.

Suppose a light ray travelling near a black hole, which has so much gravity that the escape velocity is twice the speed of light, got caught in its gravitational field. Will the light travel at the speed of light or travel at double the speed of light?Similarly what happen to other objects...
