the theory in use today states that, if you are travelling AT the speed of light, and hold a lamp, the light beam will still be going forward only at c, the speed of light, which is a constant.
that theory also states that it is NOT possible to go faster than light.
to assume that you can be going faster than light, you have to say that the theory is obsolete. But for the time being no one would know what to replace it with.
so in absence of a theory describing your situation, the speed of light emitted by a source moving faster than light, is going to be undefined. Maybe it remains the constant c?
hope this helps

Yes
Even if it were behind you. You are traveling with the light! The theory of relativity shows that it is how you perceive the universe that is traveling past you at the speed of light that changes.
According to the theory of relativity, this situation would be the same as you standing still with the light in front you while the whole universe passes you by at faster the speed of light. It does not matter whether you stood with the light with you facing backwards, sideways or whatever, relative to the passing universe.
They say that if you did travel, the show around you would be great, but you would end up in a different time or parallel universe

I agree with Infinity's answer. If the lamp is traveling with you then you should be able to see the light. It might look like it is coming right at you though and blind you in the process. I do not think that the light will encompass the space in front of you so you will not be able to see what is coming up next unless it has it's own light source. So you may fly strait into a dark piece of matter. Good luck!! May the force be with you!!

Yes - if you are travelling forward with lamp in front of you.
You are travelling say at 10times the speed of light. The lamp you are holding is also travelling along with you i.e at 10times the speed of light.
so your relative speed w.r.t lamp is zero :)
hence you should be able to see the light.
----------------------
If you travel backwards.......then you can have fun.
if you travel for 1 hour and then stop this is what you will see.
1. when you are travelling you will neither see the lamp nor its light.
2. Once you come to halt, first you see the image of your holding the lamp.
3. then you will see as if the lamp makes a copy of itself, then this new copy starts to travel backwards towards the "origin".

If u travel faster than light ,first u will be dead,second u will be in another dimension,third u will have a mass of infinity.

Yes, the speed of light is relative. No matter what speed you travel light always seems to travel at the speed of ...well... light.

Unless your mass is zero, you can't reach the speed of light. Or maybe your eyes will turn inside out and you will see the light behind you!

No, not if the light you are holding, is the only source of light.

Better yet, turn around when you travel, point it back, and enjoy the show!

good que. is the speed of light is relative or not ?
