On a personal note - myself and a friend came up with this stuff ourselves about a year ago. When you see a proton excite a gas BEFORE it enters it, it shows that entering the gas makes it go faster than light, and thus shows that its possable to travel faster than light.
The point of talking about the speed of light in a vacuum as opposed to, say, certain gases, was to clarify this. Regardless, energy is essentially massless. The fact that energy (including photons) can exceed the speed of light doesn't violate the essential principle of relativity. It would still take an infinite amount of energy to push matter to the speed of light. So no, it's still not possible to travel faster than light, or even at
the speed of light, without wormholes/other dimensions.
er, i maybe tired but im pretty sure you have got yourself a lil' confused there mate. for a start I said -*PROTON*- not photon, and a proton is certainly not a 0 mass particle like photons are as Protons are fermions and photons are besons. So yes i know that, which is why this is like "wow, a mass is exceeding the speed of light". Moreover, its not just that it exceeds the speed of light, but its instantaneous transportation also shows that it must be teleporting, and thus timetraveling.
Sorry if i didnt explin that too well. ill try to dig the info back up on that experiment too if i can find the damn thing amoungst my mess lol.
