Stark Trek - How far are we?
kqr2: I think the main problem with the Star Trek scenario is "faster than light travel".  Of course, traveling faster than light really isn't possible however most of the alternate mechanisms proposed, e.g. worm holes, etc. don't seem that feasible either.I think more realistic is that man gets a toehold on space by being able to harness resources from other planets / asteroids.  If people can become self-sufficient in space, perhaps generation after generation, we can creep out further into space.But it takes a big initial commitment and it's unlikely we'll ever resolve all the problems on earth so I'm not sure how much of a priority it will be.
