It always amazes me how the atmosphere is such a thin layer between us and space.
Yup, to me it always seemed like the almost perfect vacuum of space would Hoover away any atmospheric gases on the Earth’s surface in the blink of an eye.
The earth’s gravity holds the atmosphere in place, but my little Hoover vacuum cleaner vacuums up all manner of things the earth is trying to hold onto, no problem. And space is the mega vacuum of all vacuums, a mega-vacuum, a giga-vacuum! I guess it’s in the math.
