Maybe because we already understand most of the physics required for space flight and the boring conclusion is that huge arrays of lasers are the most feasible way to accelerate an object to a fraction of light speed.
Sure we can dream about FTL, but the physics support for that is minimal at best.
- adrianN 9y agoI'm reasonably sure that hydrogen bombs are the most feasible way to accelerate an object to ~0.03c. We know how to build bombs, and concepts for big-shock-absorber-with-bomb-shute spaceships looked feasible with the tech from 1960.
- sliken 9y agoSure, but how about 0.2c? Carrying your fuel with you has some pretty serious limitations for anything short of a fair chunk of your mass being anti-matter. However with the lasers you leave the fuel at home.
