Technically speaking, the mass effect would account for a spacecraft being capable of traveling AT the speed of light. But reducing a ship's mass--even to zero--wouldn't allow it to travel FASTER than light. You'd need some kind of wormhole for that to occur, and that's not really FTL so much as it is teleportation.
Yeah, I think there may be some pretty interesting reasons why that is the case. Now, I'm not a physicist, so please take what I say with a heavy dose of salt.
If string theory pans out (a big if), I think we'll get new insights into why the universe behaves the way it does. For example, the speed of light is approximately 186,282 mps in a vacuum. Why that speed, though? Why not 348,721 mps? Perhaps the very nature of the universe controls how fast particles move.
Assume that string theory is correct. What we detect as "matter" is nothing more than vibrating loops of energy at a certain resonance. Vibrational pattern A constitutes photons, B= up quarks, C= down quarks, and so on. Now what about the empty space we see? Well, it's not really empty at all. It also consists of vibrating loops of energy, but they're not turned "on" in a resonance that gives them mass and other properties. They have the
potential to become "particles," however. Imagine that the entirety of the universe's four dimensions (eleven according to M-theory- but that isn't needed here) is nothing but a giant unified
field of planck length sized strings that are vibrating. None of them move; instead they transfer their energy to other strings surrounding them which we describe as movement. Strange? Yes it is, but we know that quantum physics is crazy.
