this thing requires a proper calculation...depends on your speed.
faster than the speed of light?
adagio?
lento?
presto?

I'm no physicist, but this is how I understand it:
Light cannot travel faster than... well... light. Therefore, if you were travelling at any speed, and shined a light in the direction of your travel, the light emitted would still be going precisely the same speed as if you had projected it while stationary.
C=C Your velocity does not add to the velocity of the light.
So assuming you were next to the torch rather than behind it, if you were travelling (as some theoretical observer, perhaps) at the very speed of light, and then created a light in a radius around this "torch", the light travelling sideways toward you would never reach you, since it would be travelling at an angle, at the same speed you're already going, and never quite catch up to you.

If you were holding the torch then yes as the torch is already travelling at the speed of light and the light would emit from the torch at the speed of light in front of you.

No you won't.
As the torch is also travelling at the speed of light, when it is turned on then the light won't come out because the forward speed of the light coming out is the same as the forward speed of the torch, so they cancel out.
Of course, it could leave a trail of light behind you, but since you're travelling forwards at the speed of light, no light from behind can catch you up so that you can see it.

Yes, that's why it's the theory of Relativity. You are travelling at the speed of light 'relative' to something else - the Earth perhaps. But the torch is stationary 'relative' to you. So you will see the light. Somebody on Earth would not.

Yes.
It's called the Law of the Propagation of Light. The speed of light is always a constant. Even if you were going the speed of light, light would still appear to move at the speed of light. This apparent contradiction is what led Einstein to formulate the Theory of Relativity.

No. Let's look at it as an analogy: if I am traveling in a car at sixty miles per hour, and I have a bird in the car with me, and it begins to fly around, it gradually loses its inertia, and soon has to fly forward at faster and faster speeds to avoid being plastered against the back window. But let's imagine that once in the air the bird can achieve a top speed of sixty m.p.h. and maintain it indefinitely. Does the bird fly faster than me and leave the car behind? No, it stays at the same speed relative to the car and stays in place.
So, if a flashlight traveling at the speed of light in a forward direction is turned on, it overtakes the light before it can leave the reflector, the same way the car overtakes the bird before it can fly out the window.

If you were traveling in some sort of craft that was moving at the the speed of light then, yes, you would see the light. Just like you would hear noise in an airplane moving at the speed of sound. This only applies to a theoretical craft with some sort of inertia-cancelating thinger. As far as I know. >_< I learned it from my History teacher, I can't give you any more.
Try asking Nick Sagan. xD (His Treks much better than the Treks paulgar75 refers to! Nyah!)

Yes as the torch is already travelling at that speed with you!

The nearer an merchandise gets to the cost of sunshine, it is approximately 2.998 x 10^8 m/s = 6.7 x 10^8 miles/h, relative to the earth the shorter the dimensions of the article to an observer in the international in accordance to the theory of length constraction. the way I see it is that if the gadget gets previous the cost of sunshine then the article could appear like it is shifting in opposite subsequently the touch could be dealing with back. in terms of time employing the formula t = gamma x t', the place t is the time dilation, t' is the right time and gamma = a million/sqrt(a million-v^2/c^2), you will discover that element would be a adverse imaginary quantity which might propose that the gadget could be going back in time (interior the imaginary plane or area). for sure that's purely my theory.
