to go FTL, you need an object that is already FTL, same with the "epic freezing" (absolute zero).

wikipedia is not a good source

Actually it's a little different with an object going faster than light.

The reason things cannot go faster than light is that it is the "cosmic speed limit". Nothing can go faster than it (on relativistic scales, don't get into quantum transfer of information which is seemingly "instant") or otherwise a large amount of models would break down. Otherwise, Einstein reasoned, we would have different laws of physics for

every different place in the universe. Einstein's intuition was that things were simpler. So hence came the theory of special relativity, which states that:

1) The speed of light,

*c*, is defined to be the fastest speed possible in the universe.

2) Each inertial reference frame is equally valid as the next - there is not "absolute" reference frame in the universe which is unmoving relative to everything else. In more understandable terms, everything is always measured as moving

*relative to* another "still" object.

So back to the question of "why can't things go faster than the speed of light?"

The answer is in that, one of the mathematical consequences of the Theory of relativity is that the "relativistic mass" of an object increases as it moves. So when an object is going really fast, say, at 95% of the speed of light, it's mass will have increased significantly. When you get to 99.9% of the speed of light, it's mass will increase. As you approach closer and closer to the speed of light, the mass will increase more, and more, and more, also making the object harder to accelerate more and more.

So, it would consequently require infinite amounts of energy for an object with mass to reach the speed of light. It can only get really close to it - 99.99999% of it, for example.

I hope this makes sense. I tried to make it friendly to those who avoid physics like the plague.
