We've Got A Long Way To Go

New Scientist published an interesting article on ten possible ways to traverse deep space. Unfortunately, the most promising technologies won't have us going nearly fast enough the reach another solar system in our lifetimes, and the coolest ones probably break the laws of physics.

And yes, the "warp drive" of Star Trek is pretty damned impossible to build, as it requires undiscovered "exotic matter", and requires more energy than what exists in the universe to sustain. I guess for now we'll just have to find other ways to satisfy our space exploration fantasies.
