Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We're all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.

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

How?! How is there an xkcd for EVERY gawdamned thing?!

[–] ladicius@lemmy.world 31 points 1 year ago (2 children)

XKCD is an allknowing timetravelling entity.

[–] grysbok@lemmy.sdf.org 8 points 1 year ago

Can confirm. XKCD spoke at my college and signed my laptop.

Ooh, now I'm wondering if Doctor Who will make a reference... 😱

Has xkcd done an xkcd on xkcds?

Seemingly not officially but there's this

[–] petrich0r@lemmy.world 34 points 1 year ago

the unexplained meteorological phenomenon is simply dubbed a “Skrillex Storm”—because, in the words of one researcher, “It had one hell of a drop.”

[–] NewNewAccount@lemmy.world 2 points 1 year ago

This is amazing.

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

[–] themeatbridge@lemmy.world 15 points 1 year ago

Also, we'd all be dead.

[–] ladicius@lemmy.world 9 points 1 year ago

Oh, you and your facts.

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

[–] SmoothLiquidation@lemmy.world 5 points 1 year ago (1 children)

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.

[–] BarrelAgedBoredom@lemm.ee 1 points 1 year ago

I did tweak the drag coefficient while doing the math but I had no idea how to figure out what would be most accurate. The number I got there is with a drag coefficient of 1

[–] DaCookeyMonsta@lemmy.world 2 points 1 year ago

Energy would be better to look at than force, since at any distance the force is the same (mass and acceleration aka grsvoty are both static)

Fun fact

Definitely not

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