At the speed of light, time also stops for the object travelling at that speed. The observers continue to experience time. So if we travelled at light speed to a place that's 1 million light years away, we would perceive it as occurring without the passage of time. Meanwhile, anyone back on Earth would experience 1 million light years of time. Humanity wouldn't exist, in any recognizable form, by the time you got back.
So interstellar travel must involve not only the manipulation of space/speed but also time.
One of my thoughts was that if particles are just waves moving along a quantum field, perhaps it's not possible to create a wormhole, as you would need to unhinge those waves from the field their on and attach them to a different portion of the field. But maybe I'm thinking of particles and fields too much like beads on a string, and they don't actually exist like that. Maybe it's more like wave in a pool, so it's a question of finding a way to make those pools jump from one pool to another. I don't really know enough about the subject to comment.

This is why I'm skeptical about alien visitors. It's hard enough to contend with the speed of light problems, but to be able to jump from one pool of particle waves to another, like you say(and I realize your comment about not knowing enough) you would have to know what pool to jump to in the first place. How do you come up with a destination in space?
