What is the real power behind the rush to fill in complete emptyness

[littlebanger]

is there something going on when i vacuum is crated from nothing at all in the atmospher? i mean why such a big rush to fill in that gap which it seems like the power to fill it in is endless and will always happen . if something can't be replaced then that something can't be removed

as usual i have struggled to explain myself properly Thank for any comments

I agree that you have struggled to express yourself properly. I have no idea what you are asking.

You're too vague with your description. Can you flesh out your question a little more?

What do you mean by "...when i vacuum is crated from nothing at all in the atmospher..."
When does this happen?

My guess is the original post is asking why pockets of near empty space don't randomly occur in the atmosphere. It's because the molecules are bouncing in essentially random directions, combined with a huge number of molecules per amount of volume in the atmosphere (except for the outer fringes). Even if there's an instant where there is a partial reduction in density in a zone, it's quickly filled by the surrounding molecules in the atmosphere.

On a large scale, due to weather effects, there are higher and lower pressure areas within the atomosphere.

well i just mean like . if you have a rubber bottle squash it and tighten a top onto it then it can't get back to its normal shape without sucking in air . i was just wondering why can't it just leave nothing at all inside and just spring back to its shape

thanks for the answers.

Because with that you are lowering the volume of the bottle and squishing the air out. When you close the bottle, the air inside and the air outside have the same pressure, atmospheric pressure (because of the rigidity of the bottle there might be some pressure difference but we will look a situation like its a balloon or something). In order for the bottle to get back to its original shape it needs to increase its volume, but there is only that much air so to do that the pressure inside must drop and the outside pressure don't allow that, it is pressing on the bottle.

Simply put: the bottle is being acted on by a force. Over every square inch of the bottle's surface, there is a pressure of 14.7 pounds pushing inward. Let's say an average bottle has a surface of 50in^2; it is being crushed by a force of 735lbs.! Is that enoough to keep the bottle squished?
