A Gigatonne bomb sounds a little unsubtle to me, I would have thought that a stream of smaller bombs, each that give it a small push would be the best way to go. And would still be far cheaper than building some kind of nuclear powered rocket that needs hundreds of tonnes of nuclear fuel, and then launching it. Using lots of small bombs also has the advantage that if one bomb is a dud you will still move it most of the way.

quote:Originally posted by bigtimThis is a common missconception. Gravity is not a force. The force is the product of mass and the strength of the gravitational filed, ie. the quotient of the ratio force/mass.
