The alchemist has a better chance of reaching his goals.
you missed my central question- do you think we know everythign there is to know about internstellar travel.
By all we know right now, yes- you are right. But I dont assume we know everything by a long shot.
FTL travel is impossible, but wormhole travel does not violate FTL.
"In early development of transonic and supersonic aircraft, a steep dive was often used to provide extra acceleration through the high drag region around Mach 1.0. This steep increase in drag gave rise to the popular false notion of an unbreakable sound barrier, because it seemed that no aircraft technology in the foreseeable future would have enough propulsive force or control authority to overcome it. Indeed, one of the popular analytical methods for calculating drag at high speeds, the Prandtl-Glauert rule, predicts an infinite amount of drag at Mach 1.0."

I'd invoke Clarke's Rule here, but then again, in a simple universe modern science hypothesizes is made up of 7- or 9-dimensional vibrating strings, we certainly know everything there is to know about the laws of physics...
