Does cold air move to hot or does hot air move to cold?
6 AnswersPhysics1 decade agoWhy doesn't the earth's atmosphere float out to space?
I am told that space is a near vacuum so, why isn't the atmosphere just sucked out into nothingness? Please don't tell me it's gravity because I know that if you induce a vaccuum here on earth and then expose it to the air, air will rush to fill the void. Therefore, it would seem that gravity has no affect.
18 AnswersAstronomy & Space1 decade agoFollow up to the hole through the earth question...Once you reached the center, would you be weightless?
Because gravity is a mass vs. mass connection (and assuming you could withstand the heat, had an elevator to get out, had a large enough room at the center able to resist the crushing effect above, etc., etc.) would you be weightless? or would gravity pull you apart?
6 AnswersAstronomy & Space1 decade agoOf what value has the International Space Station been?
The space station has been occupied for almost 7 years now. I know that I am the victim of 'reportable' news but has there been any science produced that hasn't already been done aboard the MIR or the short life of SpaceLAB, that justifies it's expense? (Other than marathon running, tourists and the ability to have elementary students ask questions of people who just happen to be in orbit)
