Nothing magical about it, only common sense and perfectly logical.
It is pure magic, directly defying common sense, and in no way logical.
Again, density provides no reason for things to move in any direction.
Again, origin, if it actually worked, would mean an object thrown to the right would fall to the left.
Neither works.
Objects have to be taken off the surface
Sure, I can find an overhang, and pull an object down, away from where it originated, and then it falls down.
It doesn't fall back up to where I pulled it away from.
So again, where it started clearly doesn't matter.
But even more so, I can take water, and boil it and it starts going up. Then it condenses and it starts going down.
Again, where it originated clearly doesn't matter.
Stop repeating the same pathetic, refuted BS.
It just shows how utterly pathetic and desperate you are.
And what shows this even more, is how you are so absolutely pathetic, and know your pathetic BS can't work, that you need to repeatedly switch between 2 contradictory ideas.
If it is about origin, then stop appealing to density. It should simply be it originated there, so if you move it away it goes back. And that should apply regardless of which direction it is moved.
If it is about density, then stop appealing to origin. It should not matter where the object originated, or how it got to where it is. Instead, it should simply be that it is denser so it goes down.
But you know that neither of these can work.
Origin means it should go back to where it originated, not down.
And you know density doesn't work, because you have no reason for why that should make it move.
So you need to continually switch back and forth; which just has the effect of showing you know you are spouting pure BS.
where they are motionless before you throw it up.
No, I threw it down, away from the overhang.
it’s own density in a less dense medium makes it fall down
WHY?
Stop just asserting the same pathetic BS.
Why should being denser make it go down?
How does this work to generate a force?
Again, if it is accelerating it needs a force.
The same principle holds for things that rise up in air and in water, being less dense than air or water.
You mean when you ignore reality.
Back in reality we see a balance between the downwards force due to gravity, and an upwards force due to the pressure gradient.
You know, the thing you need to keep fleeing from because it destroys your pathetic BS.
The upwards force due to the pressure gradient is equal in magnitude to the weight of the fluid displaced.
If this upwards force is greater, the object rises, if it is lower, it sinks (but its apparent weight is reduced).
You certainly know a helium balloon rises up in air with no external force needed, right?
No, I don't. Because that is pure BS as already explained.
There is a pressure gradient in all fluids. This is easily verifiable and measurable.
This is an external force acting on everything in that fluid.
That includes the helium filled balloon.
That means the helium filled balloon is being pushed upwards by the air.
You know this.
You appeal to this pressure gradient when you are spamming pure BS about airplanes.
So you know this pressure gradient exists.
And you would have to be a complete imbecile to not realise that pressure gradient provides an upwards force.
If you place a scale above the helium filled balloon, and zero it, and then measure the total upwards force on the balloon, and then calculate the upwards force from the pressure gradient, you find you are missing a downwards force acting on the balloon.
So that gives us 3 reasons to need an external force trying to pull things down.
1 - In order to accelerate, an object needs a force acting on it. So for things to fall, they need a downwards force acting on them.
2 - In order for an object to not be pushed upwards by that pressure gradient, it needs a downwards force to counter it, and even in cases where it does go up, you still need a downwards force to get the resulting force on the object.
3 - In order to maintain this pressure gradient, even the air (or other fluid) needs a downwards force acting on it. Even when it is the same density as the fluid around it, or more dense than the fluid above and less dense than the fluid below, it still needs that force.
So why do you reject all this and instead wilfully lie to everyone by claiming no such force is needed and that objects just magically accelerate without a force?
Why do you repeatedly ignore this pressure gradient which destroys your delusional fantasy?
That’s why you had to make up ANOTHER non existent force
Now try that again honestly.
Due to the first real force, which has been repeatedly demonstrated beyond any sane doubt, the air (and other fluids) are pulled down, creating a pressure gradient which pushes up objects immersed in it, directly giving that force you claim is a second made up force.
But because you are so adamant about rejecting that first real force; you are now desperately forced to dismiss the resulting force as fake as well, and then also ignore or reject the pressure gradient or the logical consequences of it.
i.e. your pathetic BS falls apart, while reality with gravity continues to work just fine, with you still unable to show a single fault.
