earth\'s gravity
let's assume we could make the earth have any mass we wanted. right now the gravitational acceleration at the surface of the earth is 9.81 m/s^2. what is the minimum and maximum g that would still allow humans to live indefinately?

Everything is interlinked, so it's a stupid question. There would be no man without everything else being as it is.

Re: earth\'s gravity
how much could g go up and down for the moon to stay in orbit

Re: earth\'s gravity
Forget the moon, how much extra mass would cause the Earth to slide out to an orbit that is too cold, or pulling away mass would push us into a killer hot orbit? Or do I have that backwards?

Re: earth\'s gravity
In a vacuum, the answer to your question is that we can have no gravity and be fine, as long as we exercise and make sure we don't atrophy, and on the other side, I think I heard it was like 6 G's or something, we're just too heavy and our bodies couldn't handle it indefinitely. That could be off a bit, I'm just going from memory. But I mean, there is some point where gravity is too much for our heart to pump blood around and our organs to work and stuff.
But like somebody pointed out, it's all interconnected. Different gravity would affect all the other things on the planet which would affect us. No gravity would mean no rain and we couldn't stop ourselves from drifting into space, and too much would crash the moon into us and god knows. It's not really possible to determine all the effects, but it wouldn't take being plus or minus 2 m/s^2 to notice the vast vast changes I wouldn't think. |
