You have never, ever, provided a practical demonstration.
You can never show me gas pressure without containment, you push a rhetoric of a sky vacuum, a vast space for the gas to fill, which you have claimed it isn't filling it because it's gradieted? That's preposterous and nonsensical as you must first have containment to have gas pressure to have the gradient you claim answers the question of how you can have gas pressure without a container. God of the gaps "Gravity" is not overcoming entropy, ever. If you try to claim an imaginary downward "force" is applicable to a gas expanding in all directions then you can first mumble your way through the very obvious contradiction in terms - you won't find that in your bible books because it's clearly fucking nonsense.
