An interesting read over at cracked about some crazy space travel ideas which might be possible but it’s probably better they not be attempted. My favorite is #4: The Atom Bomb-Powered Spacecraft

Their idea was a mammoth spaceship weighing up to 7 million tons that ran on nuclear bombs. Yes, nuclear bombs. As in, you take a huge spaceship, and stick a fucking nuke under it, then set it off. These guys would have taken one look at the giant gun guy and laughed in his face.

Number two on the list doesn’t sound too appetising either!
