In the vacuum of space, there are very few particles, and they are mostly moving very very fast, which gives them high energy and high temperature. I forget what happens at 40,000 m that causes the shift from cold atmosphere to "this is space" but that's how the temperature is increasing -- as you climb there are fewer and fewer particles, moving faster and faster. permalink fedilink source parent [โ] gole@lemmy.zip 1 point 2 months ago Good question. I don't know the answer but it started to get warmer from the stratosphere at 16km permalink fedilink source parent [โ] mech@feddit.org 2 points 2 months ago Fun fact: A real space elevator would need to be 458x as long to reach geostationary orbit. At the speed of earth's current fastest elevator, it would take almost a month to reach the top. permalink fedilink source parent
