So far, all of the "laws of physics" have turned out to be true, if they were considered an approximation applicable with a certain set of preconditions.
My only hope for human kind travelling interstellar distances is to figure something orthogonal out, as even speed of light is too slow (perhaps we extend our lifetimes to span millenia combined with teleportation? :).
I want to believe. So I'll spend more time than is wise evaluating evidence. But, like, it's gotta be some really good evidence.
