lol, we are never going to go lightspeed, nothing, except light, unless we find ways to break physics like crazy.
there's not enough energy in the universe for that to happen.

Did you really laugh out loud when you read this thread?
Anyway, I think the issues of light speed travel are apparent to pretty much everyone with an interest in the topic. Even forgetting the technical issues, it'd be a pretty impractical means of travel - if the road from here to there isn't perfectly clear when you depart, you're in trouble, 'cause you can't grab the wheel and swerve around a passing space antelope at 186,000 miles per second.
I find it interesting that nearly all science-fiction in popular media uses some alternate method of travel. Star Trek warps spacetime, Star Wars has hyperspace, Battlestar Galactica makes FTL spacefold jumps, Stargate pokes wormholes in spacetime, etc. Trying to move at extraordinary sublight velocities has pretty much been abandoned in both practical science and entertainment.
