minus-square@[email protected]linkfedilink9•9 hours agoI remember that video, but I‘m not sure it is comparable — air might flow faster than water [citation needed] and there might be less of it [citation needed].
minus-square@[email protected]linkfedilink2•5 hours agothere’s more water than air (mass-wise). Above you, atmosphere scale height is 8 km, with a density of 1.25 kg / m³. That makes 10^4 kg of air above your head per m² surface area. To get the same mass of water per surface area, it would only have to be about 10 m deep. But the ocean is kilometers deep in most places.
