If you don't know what being stringency, so how you can get whether it is relevant or not?
He was stating that the definitions he obtained while searching for it were not relevant to making objects fall (i.e. replacing gravity).
If you have a different definition, which is relevant to replacing gravity, feel free to provide it.

In short, no image, no proof.
You would say the same even with images, just declaring them to be faked or photoshopped.
The images are not needed for the proof.
Objects are known to fall in a vacuum, so we know it isn't the air pushing it down.
In fact, we know the air resists its motion, with objects having a larger surface to mass ratio being slowed more than objects with a smaller surface area to mass ratio.
If it was the air pushing things down it would be the other way around, with lighter objects falling faster than heavier objects.
i.e. we would expect to the see the feather drop straight to the ground as the air can easily push it while a steel ball bearing would just float around as the air struggles to push it down due to its mass.
Instead we see the exact opposite.
And again, buoyancy also shows that the air is not only resisting motion, but actually pushing objects upwards.
This can be demonstrated by weighing an object in a vacuum, and then weighing it in air and observing that the weight in air is less.
Yet if the air was pushing it down, then more air (or air instead of no air) would cause the weight to increase.
We can also see this with helium balloons which float in air but sink at low pressure.
This can further be demonstrated with other mediums/fluids, such as water or mercury, where buoyancy causes objects to float.
We also know this isn't just density magically sorting itself out as we can measure the pressure in these fluids and note the pressure is higher the lower you go, with this pressure differential creating a force which is the buoyant force.
So we can conclusively know that air is not pushing objects down, nor are other fluids.
Your entire attempt at disproof is "I don't understand buoyancy so gravity is fake"
Neutrally buoyant things have the force due to buoyancy balance the force due to gravity.
The pressure of the water above the object is less than the pressure below the object.
This causes an upwards force, which is countered by gravity's downwards force.
Now care to actually address the issue?
If you like I can provide the full explanation of buoyancy again and show how it supports gravity rather than refutes it.
