but it's not lmao

2019-07-18 05:40:25 UTC  

¯\_(ツ)_/¯

2019-07-18 05:40:27 UTC  

literally all pressurized containers have a gradient

2019-07-18 05:41:06 UTC  

1

The pressure gradient would be in any container that is in a gravitational field. It's just that in most situations, the gradient in air is too small to worry about and it is ignored.

You can determine the gradient the same way you do pressure underwater. You just multiply the depth of the fluid by the density. For very large columns, the density of air would vary. But for a small container, we can assume it's nearly constant, around ρ=1.225kg/m3
That means near sea level, if the pressure at the bottom of a container is 1atm or about 1013mbar, the pressure 1m higher would be less by the weight of that amount of air.

ΔP=ρgh
ΔP=(1.225kg/m3)(9.81m/s2)(1m)
ΔP=0.12mbar
1m up in your container, the pressure is less by about 0.01%.

huh

2019-07-18 07:07:31 UTC  

that's actually kinda illuminating

2019-07-18 07:08:55 UTC  

it shows that even with constant density atmosphere, you could get a pressure gradient

2019-07-18 07:29:37 UTC  

imagine having to prove we aren't in a container

2019-07-18 12:13:19 UTC  

Imagine having to prove we are

2019-07-18 12:33:49 UTC  

"second law of thermodynamics!"

2019-07-18 12:39:42 UTC  

I mean actually proving it’s existence

2019-07-18 12:41:01 UTC  

what is this debate about

2019-07-18 12:44:06 UTC  

Wether there is a dome or not

2019-07-18 12:44:17 UTC  

It’s not really a debate at the moment

2019-07-18 12:44:44 UTC  

ok what is your opinion

2019-07-18 12:45:44 UTC  

No existe

2019-07-18 12:57:39 UTC  

ok i guess we have nothing to debate about xd

2019-07-18 13:02:41 UTC  

Lol

2019-07-18 13:32:35 UTC  

If we were in space all the air would be gone

2019-07-18 13:47:53 UTC  

It isn't gone thanks to gravity

2019-07-18 14:00:14 UTC  

@Citizen Z how come?

2019-07-18 14:12:28 UTC  

Entropy

2019-07-18 14:14:01 UTC  

Entropy is the reason we have a pressure gradient

2019-07-18 14:19:54 UTC  

I don’t think you understand entropy citizen

2019-07-18 14:51:42 UTC  

@Citizen Z so because of the dome, we have a constant pressure everywhere on the planet not matter the altitude?

2019-07-18 15:06:21 UTC  

Even with a dome, there'd be a pressure gradient. Atmospheric pressure is caused by weight of the atmosphere, so the higher your altitude, the less pressure would be exerted on you.

2019-07-18 15:28:24 UTC  

buoyancy and density would not explain a pressure gradient.... only one thing would explain that...

2019-07-18 15:29:06 UTC  

Buoyancy requires gravity

2019-07-18 15:29:16 UTC  

shhht they don't know that :P

2019-07-18 15:41:15 UTC  

Here's a great video of a density tower in micro gravity to demonstrate how buoyancy requires gravity:

2019-07-18 17:23:43 UTC  

is there a debate to be had regarding this image?

2019-07-18 17:29:34 UTC  

right, so in 2014, when no one knew, he was supposed to know?

2019-07-18 17:30:38 UTC  

And so the plot thickens...

2019-07-18 17:59:14 UTC  

I guess he was silenced by the big evil corp that guards Antarctica :/

2019-07-18 19:52:18 UTC  

Technically buoyancy requires a force that acts on the whole system not gravity. Its just the only other possible forces i couls think of wouls be Fc (centripital force (or centrifugal force one of the 2) which would say we are spinning very fast in a circle. Which is ok i guess. Theres not really anuthing wrong with it

2019-07-18 19:53:05 UTC  

there is though, FE believe the earth is stationary

2019-07-18 20:03:06 UTC  

Most of them yes. But not all of them

2019-07-18 20:05:33 UTC  

The non-religious ones don't find it necessary to incorporate geocentrism.

2019-07-18 20:14:40 UTC  

the non religious ones make less sense because what is their excuse?

2019-07-18 20:15:02 UTC  

Purely distrust in the government, I think.
