The good news is we’d be pretty dead if we had no atmosphere anyway, plus there’d be no clouds.

    What if a rainstorm dropped all of its water in a single giant drop?

    If there was no air I'm pretty sure clouds wouldn't form in the first place.

    If there wasn't an atmosphere to provide resistance, there wouldn't be water vapor suspended in it, there wouldn't be dust particles suspended in it to provide places for condensation to happen.

    With no air resistance, there wouldn't be rain in the first place.

    Fun fact

    Definitely not

    A cubic foot of water weighs just under 62 and a half pounds. Atmosphere to slow it down or not, having that land on you from altitude would hurt.

    They mentioned a 2 in. thick sheet of rain falling, which is ~288 cubic in. per 1 foot x 1 foot area, about 10 lbs of water. Falling as a flat sheet at terminal velocity would hit you with a force of 127 newtons. What that means as far as injuries go I have no idea. I'm sure it'd cause a nasty headache at the least though.

    Fair warning, I'm terrible at math so I could be completely wrong

    Terminal velocity is only as fast as it is because of air resistance. With no air resistance, the only limiting factor of speed is starting height.

    It’s like the experiment with the feather and the hammer they did on the Moon.

    Reminds me of that page in the Bone comic where the snow comes down all at once. I loved that scene!
