Will intersteller space-travel ever be possible or even feasible? Given the fact that nothing unaided can even approach the speed-of-light or surpass it (you start to either shrink or stretch, I forget which, once you go 80% light-speed), how would it be possible without some form of traveling through worm-holes, or using a string-theory method, etc. (forget black-holes, those will just kill you).
Therefore I'm deeply sadden to have to say to you that I personally believe (even though I'm a HUGE Star Trek:TOS and TNG fan) that unless some form of solution to the problem of faster-than-light speed can be found, we're DOOMED to remain in our own solar-system until the END-OF-TIME (unmanned space-craft not included). Do you think instead we'll have to settle for half-light to three-quarter-light speed multi-generational ships? THAT WOULD SUCK!!!
