So genuine question who's going to area 51

Me that's a stupid question

I am going !!

Ayy time to unveil the truth am i right

@Mono can i be your waifu

Urmm sure

You are a girl right?

Sksksksksksk obvs

4 people are going to area 51

me and the other 3 fingers

@Akhanyatin yes. Space is a vacuum with maybe a few chunks od atoms floating around. But as distance increases gravity unproportionally decreases. Eventually the molecules with kinetic energy escape and the gravity is too weak to pull them back in. Therefor we get a vacuum that escapes earth's atmosphere. Technically the pressure in space isnt zero but it essentially is zero for every calculation purpose.

Vacuum, space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there.

vacuums

do

not

suck

They dont

High pressure pushes

@the21cat RIP I thought you were a flat earther lol

I was trying to get you to admit that there could be a pressure gradient

it was way easier than expected... but then you're not a FE

FE'ers, how long does it take to fly from Argentina to Australia?

21 cat. Yer loonier than a 3 dollar bill

a pressure gradient indicates a container

every container of pressure has a gradient

why would we deny the pressure gradient when it is characteristic of a container?

lmao gas fills its container so why would there be a pressure gradient in a container

it should be constant

and it isn't constant on earth because we're not in a container

but it's not lmao

¯\_(ツ)_/¯

literally all pressurized containers have a gradient

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

that's actually kinda illuminating

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

imagine having to prove we aren't in a container

Imagine having to prove we are

"second law of thermodynamics!"

I mean actually proving it’s existence

what is this debate about
