It doesn't matter how fast or slow. The point is made and you are now starting to get it, until you decide not to.
It does matter.
Quite a lot.
Consider a simple hollow steel cube, with a gas outlet attached.
We place it on a balance and weigh it.
We then attach a pump and remove the majority of the air from it.
We then re-weigh it.
If your nonsense was true, it is displacing more air, and should weigh more. But in reality it is observed to weigh less.
And this is where speed comes in.
If the air can go through the wall quite quickly, then you would never be able to reduce the air inside it significantly at all.
And by the time you took it back to the balance, it would be just as full as it was before.
However, if it proceeds at an incredibly slow rate, then there is plenty of time to get most of the air out and place it on the balance to weight it again.
It will then slowly enter it.
We can see the same with a helium filled balloon.
If it was incredibly fast, the helium would just leak out of the balloon as you try to inflate it, so you would never get a nice buoyant balloon.
But if it is slow, it will be inflated, with the helium trapped inside, slowly leaking out over the course of days to weeks, with the balloon shrinking as it does and getting less buoyant.
So the rate is very important as it dictates what we would be able to observe.
And the incredibly slow diffusion of helium through it is irrelevant for the discussion at hand.
We can get materials which are air tight, with some displacing more atmosphere and weighing less, while others displace more atmosphere and weigh more.
It is as if there are 2 separate effects, one (downards) which scales based upon mass, and one counter to that (i.e. upwards) which scales based upon fluid being displaced.
And this also relates directly to the sieves. Again, if nothing is air tight, how can the sieves stop the air or part of it going through?
Not if you have no real clue about denpressure.
Even more so if you do have a clue about denpressure.
There is simply no reason at all for these observations.
And again, not if you refuse/fail to understand pressure.
And again, it only appears to have a reason if you are intentionally seeking out an incredibly superficial understanding.
If instead you seek out a more in depth, connected understand, you very quickly realise so much of the world simply can't work in your fantasy.
As has been explained to you repeatedly, the big issue here for the existence of solids and liquids is the absence of pulling forces.
You need pulling forces to hold solids and liquids together.
No pulling forces, and they all fall apart.
In your fantasy, with no pulling forces, a "solid" object should behave just like a liquid, freely flowing, freely being pushed around, as there is nothing to PULL it together.
I repeatedly tell people they have their own thoughts and are welcome to them.
Until it comes to something like gravity, the round Earth, free space, or pulling forces; at which point you boldly claim it to be fictional garbage and do not want people to accept these parts of reality.
I never tell anyone to believe in denpressure. I merely say, if you want to understand it then put in the effort instead of trying to ridicule putting up your shield.
Again, there is a very big difference between believing in something (or accepting it) and understanding it.
I understand your nonsense, and this causes me to realise it is nonsense.
Pointing out why your BS doesn't work doesn't mean we don't understand it or that we are trying to ridicule it.
You on the other hand use every trick in the book to beat down those who do not follow your strict indoctrinated beliefs.
No we don't.
We use evidence, logic, reason. Things your garbage lacks.
You use it every day so there's no fail on my part.
No one uses your delusional BS.
This is just a pathetic lie you keep telling yourself.
So much of reality relies upon your delusional BS being wrong, with people using things other than your delusional BS to make things work.
It appears it hasn't so it works.
No one has adopted your delusional BS, so no, it doesn't mean it works.
It's only the wording and reasoning that changes.
Yet you can't provide any of that reasoning. Instead you just repeatedly assert the same pathetic lie that it all works the same.
But that is where you really shoot yourself in the foot.
If it all works the same, why should anyone believe your delusional BS?
If it all works the same, that means we can stick to mainstream science, which has the same results.
Again, in order to justify your BS, showing it is real and gravity et al are not, you need to provide an example where they differ.
I have already provided plenty where your delusional BS produces a result which is not observed in reality.
