I saw 2010 and other stuff. You send your probe, ship, whatever around a planet. It comes in at an orbit that brings it very close to the planet, but it does not crash, and shoots out on the other side, escaping orbit at a very fast speed. How fat depends on the trajectory it comes in at, and the mass of the objection you are banking against to pick up the speed. So take a voyager size probe, and using the sun, if we did the math perfect, and nailed said math perfect, how fast could we shoot that probe out into space? Like .95 speed of light or something like that? Anyone thought about this kind of stuff? We need to figure this kind of stuff out, no stagnate here until our destruction...
