If I have the math right, the crossover point where the relativistic energy exceeds the rest mass (...) (21 years ago, 24-Jun-03, to lugnet.space, FTX)

And if it's comparable to a sports car's engine, I'd think heat buildup would be a bit of a (...) (21 years ago, 24-Jun-03, to lugnet.space, FTX)

| | | | | (...) But you're going at .95c, which means you're hitting lots of particles per second. If your ship has a frontal area of 9 sq meters, and 90000 square centimeters, that's 90,000 molecules you're running into for every centimeter forward in space (...)

| | | | | (...) Jonathan, The craft would indeed contact a lot of particles (about 2.85x10^14 per second per square meter of frontal area at 0.95c) but the energy per particle is very small. So the total energy of those particles seems manageable in (...) (21 years ago, 24-Jun-03, to lugnet.space, FTX)
