it is a gradient

Pressure goes down as we climb altitude

And in some point there is no pressure anymore.

Or very very very little.

very far away

@Minotarus Are you saying you can have gas pressure next to a hard vacuum without a container? Doesn't that violate the 2nd law of thermodynamics?

the canister can be considered as gravity

What's gravity?

"Are you saying you can have gas pressure next to a hard vacuum without a container? Doesn't that violate the 2nd law of thermodynamics?"

also, is thermodynamics not to do with heat???

Where does the 2nd law say that?

So and i said there is no hard vacuum.

Please read what I write.

"The second law of thermodynamics places an observation of EVERYDAY LIFE into a formal statement:
Heat flows spontaneously from a substance at a higher temperature to a substance at a lower temperature and does not flow spontaneously in the other direction."

h

🤦

So that doen't voilate it where does it voilate there rule?

thermodynamics is trying to fined a equilibrium, gravity is preventing that from happening

gravity as in the bending of spacetime ?

In other words,
Laws of Entropy (2LOT): Unless it is hindered 'purposely'; in "Nature"....
Heat Flows from Hot to Cold (Always !!)
Energy Concentrated to Dispersed (Always !!)
High Pressure to Low Pressure (Always !!).

It has NEVER BEEN VIOLATED ...

@Nico2020 What is gravity?

we are basing the whole globe model on a theory

Heat Flows from Hot to Cold (Always !!) But that isn't the case in space

its not even a theory reall or a hypothesis gravity is more like an idea

easiest way to understand is mass attracting mass

yeah thats not a fact that happens

@Minotarus You have to prove space.

@Nico2020 What's mass?

So where is the heat?

You speaking of?

Earth?

mass
/mas/
noun
1. a large body of matter with no definite shape

@Nico2020 No matter is mols or 10^23 atoms.

Wrong

Gravity is messaurbale

?

So what's mass then?

weight times accerlation

gravity is relative density thats all

this is elementary physics, come on guys. I'm gonna get some ice cream or something

Alright so a brick on the floor is under zero acceleration, so
bricks weight = 2kg
acceleration = 0 m/s^2
2 x 0 = 0
So bricks have zero mass correct?
