There is no proof drag is causing objects of differing densities to fall at different rates of acceleration.
There's is proof density is causing objects of differing densities to fall at different rates of acceleration.
What you're claiming doesn't have any proof to it and while the objects have different densities, there is something physical to show why they fall at different rates. You're expecting me to dismiss a physical fact (different density levels) and instead believe something that makes less sense?
If the objects had the same density you might have a point, but they don't. This drag you speak of is not even a variable. The only variable is the density of the objects, which should be a clue as to why one falls faster than another.

The faster a ball pushes on water the more water particles there are and it slows the ball down, right... but this is because the ball has enough density to sink at all in water, so what?
So what if the force is proportional?
It can be!
That doesn't somehow magically nullify anything I am pointing out, just the same as having drag there doesn't nullify it.

Drag isn't "a variable" if water is used in one tank and water is used in the other tank.
Scientists drop things "in a vacuum" all the time because it is the one environment where no one could measure any difference in the rate of falling objects due to the density differences being too drastic.
I mean you're dropping solid objects in a zero density environment, of course they are going to appear to fall at the "same" speed.
People just haven't worked that out yet, or they are pushing an agenda and know it full well, either way I am not interested, I want the truth, not some stupid fantasy that never gets proven (not even one component of it does).
