That depends on the container.
Let me put this in a simple way...as I tried to do earlier.
If you have a perfect sphere and pressurise it then you have no stacking. It's equal.
Why should the symmetry of the container matter?
Here is your prior claim:
In the container you are not stacking naturally. You are forcing a compression by trapping it inside the container. Therefore there is no natural stacking. It uniform, like you say.
With the Earth dome there is natural stacking and it isn't uniform.
You made no appeals to the shape of the container and said that by trapping air inside it you make it so there is no natural stacking and thus it is uniform.
Why completely change that and pretend it only happens to spherical containers with nothing inside?
Is it because you realise it just refuted your model, so now you need to patch it?
So good job contradicting yourself and refuting your model yet again.
It doesn't push up as such. It resists by pushing against the atmospheric stack that is using each stack under it to use as a leverage
So it doesn't push up, but it pushes up?
It doesn't matter if you want to label the push up as resistance, it is still pushing up.
I know we're going way off track here but there's a method in my asking, as you are aware.
There really doesn't seem to be.
Yes, we need to establish a system of units to be able to quantity how much something weighs.
The stack of atmosphere under the water is far greater a resistance to it because it is not up against the upper atmosphere pushing that water down.
Again, the card doesn't just cover the water. It extends over the edges and you can do it with a wide variety of cards and glasses.
Again, it doesn't matter what resistance there is unless that resistance is really an upwards force. Without an upwards force to counter the downwards force of the stack above, the card would be pushed down.
along with the extreme low pressure inside that cup
Which is completely irrelevant unless the atmosphere below pushes up.
So going to admit the atmosphere below pushes up?
If so, you are back to not having an explanation for why things fall.
If not, then you have no explanation for why the card doesn't fall.
We need to understand a weight measurement to measure the mass of anything.
No we don't.
Just because you can only think of determining mass based upon weight doesn't mean everyone is like that.
Mass can be measured independent of weight.
It also disproves the fictional spouted gravity stone dead...but that should become obvious to those that pay attention.
No, what is obvious to everyone paying attention is that your model is complete garbage unable to explain even the simplest things like why do things fall. Any attempt at an explanation is easily destroyed by even a small amount of thinking about it, or experiments which are quite easy to do.
It is also obvious that you are only bringing up gravity like that to pretend there is no alternative, even though you are yet to show a single problem with gravity. But like I said, if you want to discuss gravity, do it in another thread.
Anyway, once you stop the upper atmosphere from pushing down on the water in the cup
Focus on the card first.
The card extends beyond the cup and thus the atmosphere is still pushing down on it.
The cup prevents this, so even with a small amount of atmosphere trapped in the cup of water, the water is only pushed on by a small amount,
And this small push, without a push from below, is enough to move the object.
If you want to focus on the water, then we can see that your explanation still fails. Take the card away and the water falls.
That vessel is evacuated of it's air by being replaced by denser fluid.
Well that's the first time I have seen you bring up this pile of garbage.
Just what makes you think that?
You have previously (mostly) accepted how evacuation of such a vessel works:
You have a chamber effectively sealed from outside, but open to the inside. You make this a low pressure region which results in the pressure equalising and thus the air flowing from the vessel to the chamber. Then you switch the seals and have it open to the outside, and then compress it making it a high pressure region which pushes the air out.
Where does this magic denser fluid come in?
If you can't grasp this then you're not only taking one step back you're sprinting back to a place where there's no hope of you understanding.
So if people don't just baselessly accept your garbage you just repeatedly insult them?
