So close... and yet still a freeking impossible distance away.
Oh.. it's just 11 light years away. That's a small number, right? As much as I'd like to be able to say we have a "warp drive" or "jump drive" or something like that... at the moment 11 light years might as well be 11 million light years. it makes no difference to our ability to get there.
Exactly. Even if we DID build an Orion nuclear spacecraft (http://www.spacedaily.com/news/nuclearspace-03h.html), at best we'll get 1/10th light speed, and it would take the equivalent of several thousand Saturn V launches to build the ship in space. So we're talking at best a 220 year round trip, IF everything went right.
