no. the beam will still travel the speed of light unless acted upon by another force. just because you are traveling the speed of light in one direction, doesn't mean the beam cant do the same in the other direction. i hope that answers your question.

The beam would be red shifted to an infinitely long wavelength. Basically, you would perceive nothing traveling away from you at the speed of light.
Why? Because light always looks to the observer to be traveling at the same speed - in a vacuum, no matter how fast you are moving, light will appear to move at the same speed - its the only constant, everything else is relative to the observer's frame of reference.
Regardless of the frequency of the light emitted, you would never effectively emit a wave - the emitter is traveling at the same speed as the emitted wave.
Looking at the same light source pointed to the front of the craft, you would see light moving away from the ship, again at what looks like the speed of light, but this time, the wavelength would be zero due to it being compressed.
Either way, nothing - infinite wavelength or infinity - zero wavelength - the nothing or infinity travels away at what looks like the speed of light to the observer in the ship.

First, it is impossible for an object with matter to go the speed of light so, no, the beam would travel away from you at the speed of light. From someone viewing you from the outside, the closer you get to the speed of light the redder would be the beam because the time between each pulse of photons from the light are stretched farther and farther apart.

The answer is simple: the light beam will not "just float" from anyone's point of view -- it will travel at exactly the speed of light from EVERYONE'S point of view.
Of course if you were traveling at the speed of light, time will have frozen for you -- you won't have time to play with any flashlight before you either smack into something or the universe comes to an end.

No, for several reasons. First, traveling at the speed of light requires an infinite amount of energy for any object with mass, so the whole scenario's impossible. Secondly, the speed of light is constant for all observers; the effects of Special Relativity cancel out all measurements that would reveal absolute motion. So, from the perspective of someone on that spacecraft, the flashlight would just shine backward in an apparently completely normal fashion. It would look strange to someone beside the spacecraft, but the behaviour of the light would be normal for them too.
It's impossible to view an electromagnetic wave stuck at one point in time. Realizing this was what led Albert Einstein to formulate Special Relativity.

this question has been asked so many times...(per theory) if you are driving your car in
space or on the earth and turn your headlights on...well since theory is that if you reach
the speed of light you become light therefore your car and you are no longer a solid
visible item. So therefore there will not be any headlights to turn on, you wont be there
to turn them on so therefore the answer is NO.
In the matter to time stretching...this is so the human mind can comprehend the speed.
At 186,282 mps you would be moving so fast so you could cover that distance in 1 second.
So in essence time does not change you are just fast enough to get more done in a second
so a second seems longer.

No it will not.. But it will elongate as youi are going in the opposite direction of the beam. That being the situation the beam will just get longer and longer. Should you slow down it will pass you. Causing friction in which combustion will occur and you will be so far into outer space a fire truck will not be able to reach you and quell the fire that is burning your sorry butt for traveling to outer space when your mother said dont leave the yard..But did you listen NOOOOO you just went ahead and left the yard..That will teach you.

Light is the same at any speed, however if you are travelling at the speed of light things move so fast past you that light can't show them.
Your own eye can't show them.
If they move past you you'll see them for a faction of a second, no more.
I mean they are moving at 186,000 miles per second
What can you see at THAT speed!

The beam would move away about two cm and then red shift to nothing.

No it will travel at the spped of light away from you. u will also observe it to trvel away from u at the speed of light as your reference clock will slow down relatively.
