(...) That may be true, but I don't think anyone knows for sure, because we haven't tried going that fast yet. My spacecraft follow a very "hard SF" policy - no FTL travel, no artificial gravity, etc. But that's not to say that it's the only way... (...)

Hi. Gravity generators per se are not in violation of the laws of physics. However, they are far in advance of any current technology that we have. In order to generate an artificial gravity field, without the use of centrifugal force, we'd have to (...) (23 years ago, 21-Jun-01, to lugnet.space, lugnet.loc.au)

Wrong! Ion rockets are in use now, and have been for 30 years. They're just not big enough to for sub-orbital work. See (URL) Drew ----- Original Message ----- From: "Kyle D.
