Title: Gravity Effects on Gases Post by: connorp on Sep 4, 2013 So let's say we found a way to transport gases out of the atmosphere and into outer space. How far away would the gases have to be transported from Earth's surface as to not have gravity pull them back into the atmosphere?
Title: Re: Gravity Effects on Gases Post by: mikael on Sep 4, 2013 There's always gravity being exerted on an object no matter how high you go. I'm assuming you're wondering about the "point of no return". That I don't know the answer of :( I'd assume anything beyond the ionosphere would be that point.

But by the looks of it, this would happen around the thermopause, correct? |
