Well, first of all, it would really be good night moon! With the reduction in gravity, the moon's orbit would (quite rapidly, I think) get bigger until it escaped from Earth's gravity entirely. Then tides would get very weak, because only the influence of the sun would be left. We might have more earthquakes and volcanic eruptions; you need to talk to some of the physicists at USC or UCLA. Weather would also be affected; air masses might move more rapidly, and air pressure would decrease. Second, it would play hell with Olympic records. Everyone and all the other critters could jump higher, run faster, and lift bigger objects (although they would weigh less while having the same inertia; complicated, no?) Or could they, with thinner air? Trees might grow higher; they could pump water up to the top easier, and with lower air pressure winds would be less damaging. Birds would have less weight to lift off the ground, but air would be thinner; might even out. Probably, they also have biophysicists at USC and UCLA, who have been thinking about the effects of reduced gravity in connection with the space station, etc. —Dr. Richard Hart, Cheyenne, Wyoming Damn. I was just hoping it would eliviate some of the weight. —Andy
