Haven't you figured it out on your own?
I figured out based upon gravity and the property of gasses, that the atmosphere should have a pressure gradient, just like all fluids.
And as a gas, it wont just collapse.
So no, I haven't "figured out" your entirely baseless claim with no basis in reality; unless by "figured out" you mean recognise it is pure BS.
As for your image, the question is why is there a pressure gradient?
And if you want to claim it is based upon density, why isn't the lowest layer a layer of CO2, followed by a layer of oxygen, then a layer of nitrogen?
It seems it doesn't layer based upon density at all, and instead the gasses are quite well mixed.
Instead, it "layers" based upon pressure. With the gas near the surface being at the greatest pressure and the gas higher up being at a lower pressure, with that pressure (and temperature) dictating its density.
If it was just magically density, then I should be able to create an airtight box, pump loads of gas into it so it is a nice high density, and then open the lid and just have it sit there.
But instead, the pressure pushes it up.
Gravity causes only the fall of objects, based on the idea that objects with greater mass exert gravity on objects of lesser mass.
Only if you pretend that that "object" is the only thing in existence (other than what it is falling towards), and everything else doesn't exist.
Again, what you are saying here is like saying, if you get a see saw, and put a light person on one end and they are close to the ground, and then a heavy person on the other, gravity can't explain why the light person goes up.
It is dishonest BS which has already been refuted.
Look at a sky diver, what happens when they try to fall through the air? They need to push the air out of the way, compressing the air in front of them as they do so, which in turn slows them down.
And guess what? The same happens with the air.
In order for air to fall down, it needs to push the air below out of the way or compress it.
Alternatively, now with what you are saying, everything should just be a single point at the core. That you shouldn't be able to walk on Earth, gravity should cause you to fall through the ground and into the centre of Earth.
Of course, this entirely ignores the fact that you can't just fall through a solid object. You would need to push it out of the way.
But again, the same applies for fluids, it is just much easier to push out of the way.
So yet again, the delusional BS you are spouting is so far removed from reality it isn't funny.
Through understanding of what gravity entails, you don't get to pick and choose what falls and what doesn't.
I don't get to choose, simple physics does.
And that includes not being able to force everything into the same point.
Again, going back to that box of compressed air. When you open it, that high pressure air pushes the air above out of the way.
The more you compress a gas, the more it pushes back.
So what happens with gravity? Well that air above is pushing the air below, compressing it.
This compressed air below in turn pushes the air above up, keeping it supported.
This directly provides the pressure gradient.
The pressure gradient should be the density of the fluid times the value of g at that location.
As an approximation for a small height change, (so the density and value of g remains roughly the same) the change in pressure should be roughly rho*g*h.
And this is what is observed.
If the pressure gradient is greater than that, it means something has pressurised the air and so that air pushes back up to expand.
And if the pressure gradient is lower than that, it means something has removed the air, and the air can't hold the air above it, so that air falls down, to compress the air below and get that pressure gradient back.
And this pressure gradient will also act on EVERY object in that fluid, pushing it upwards.
It is then a competition between the upwards force from the pressure gradient and the downwards force from gravity.
If gravity wins, the object goes down. If the pressure gradient wins, the object goes up.
Different layers of air is consistent with buoyancy theory.
No, it isn't, as you cannot explain the pressure gradient.
You cannot explain why this pressure gradient doesn't push things up.
You cannot explain why it is a pressure gradient, rather than actual separation based upon the density of the components of air.
However, all of the points you have claimed are entirely consistent with gravity and the RE.
You lying about it wont change it.
Again, gravity explains it, your BS can't.
You do not understand your own theory.
I do understand it, which is why I recognise your claims are pure BS.
Conversely, you are desperate to reject it at all costs as it destroys your fantasy.
So which one has a vested interest? YOU!
