Thus, that atom is effectively dealing far, far more energy than 1.5E-10 watts. Not (...) (22 years ago, 23-Jun-03, to lugnet.space, FTX)

Well, in the space-ish situation, the number of particles you're hitting will only come down to size; regardless of its shape, a ship shaped like a perfect lozenge will hit the same number of particles as a ship shaped like a cube, if their (...)

If you minimize the amount of forward contact on the front, less particles would hit it, causing less overall damage. (...) (22 years ago, 23-Jun-03, to lugnet.space, FTX)
