Theoretically - Yes.

Theoretically, yes. But only if you were already travelling faster than the speed of light. There's no way to actually get there, but if somehow you were travelling that fast already there's nothing in the theory that says it's impossible to continue. The problem is acceleration, not speed.

Scientists have actually accelerated a particle faster then the speed of light for a very brief moment. So yes! Also they slowed down a light beam to 1mph but unless energised will fade away in seconds.

Yes, it is possible to go at the speed of light in a vacuum (light goes slower in things like glass or air) and even faster, but there are catches:
You can go as fast as light in a vacuum if you have no mass - photons ('particles' of light) do this all the time.
You can go faster than light in a vacuum if you have negative mass, or if you go backwards in time. Tachyons are postulated particles that do this.

Actually I can think of only one thing that can move faster than the speed of light and thats the speed of dark. You see the dark has to always stay ahead of the light, so its faster!!!!

It is possible but only when you can have a source of infinite energy
The equation of kinetic energy( KE) for a particle in motion with velocity v is:
KE = m ( 1/ â(1- (v/c)^2 ))
So the as v tends to C the change in KE tends to infinity which means that you need to do infinite amount of work on the particle to make its velocity reach c(which is the speed of light).

i suppose in theory everything is possible. Though there are no means known, even in theory, that anything can travel faster then the spead of light. look at a black hole for instance, its caused but the mass inside being so big, that the pull of its gravity is so strong that even light can't escape.it goes in but doesnt rebound out. thats why we cants see anything there.

It's all down to the reference point. If you have two travellers moving away from each other both travelling at 0.6 the speed of light then they are technically moving away from each other at 1.2 times the speed of light (time for an aspirin, one of me headaches coming on).

neither. The speed of light is the speed of electro-magnetic interaction, it is not possible to exceed this nor match it using anything made of matter (spacecraft or whatever). relativity does not allow. E=MC2

You can travel close to the speed of light, you can never attain it or surpass it.
