Regardless of what you say you're udner some kind of illusion that tehre's no pressure inside the chamber.
A lie by you. Please quote where I ever posted such a thing.
There’s a reason vacuum gauges read a whole range. Vacuum gauges read when pressure is below atmospheric pressure.

A simple gauge shows the reality that different degrees of negative pressure / vacuum is expected.
And even posted about how much vacuum can realistically be drawn for a AC system as an example. Where moisture and air has to evacuated before refrigerate is added to ensure proper AC operation.
Vacuum pumps work against a close system .
That’s why they can evacuate an AC system of air and moisture so the system can be filled with refrigerant to work and not freeze up with moisture.
You're not offering anything.
What is it you're trying to offer?
No. I’m offering reality that vacuum pumps are used to evacuate air and moister from AC systems in preparation for adding coolant.
What Is Refrigerant Evacuation?
Refrigerant evacuation is the removal of moisture, air and non-condensable gases from a refrigeration system.[3] During this process, a vacuum pump is used to draw the sealed HVAC system into a vacuum. This removes air, nitrogen and moisture from the unit.[4]

Deep vacuum method will require you to pull vacuum down to 500 microns or less (ideally less than 200 microns to ensure no moisture at all).
Once you have reached your vacuum isolate vacuum by shutting the ball valves on your core removers and perform a rise test for 30 minutes.
It should not rise more than 100 microns. If it does break the vacuum with nitrogen, then perform evacuation again to ensure the removal off all contaminants. You may need to change oil in the vacuum pump, I recommend changing after every use! This is why it is best to have a variety of vacuum pumps as you don't need a 230 litre per min pump on a domestic fridge.

Now stop trying to avoid the question by lawyering it to death. And stop trying to change the subject from the meat of the post.
Why does a feather fall faster and faster in a chamber as a pump draws out an increasing amount of gas molecules below the amount found at one atmosphere until the point a feather will fall at the same rate as a coin or bowling ball.
Explain what you mean by a pump drawing our gas.
I didn’t post “drawing out gas.”
A vacuum pump literally provides the prime mover to reduce the amount of air molecules in a closed space that can seal out atmospheric pressure. Reduce the number of air molecules for a given volume less than what is found at one atmosphere.
We have been over this countless times. Use the pump to move gas molecules out of the chamber, and move them to atmosphere. Enough air molecules can be removed until air resistance becomes negligible to the point a coin, bowling ball, feather will drop at the same rate.
Now. Stop changing the subject. Why in the delusion of den pressure, why does a feather fall faster in a chamber where air molecules have been evacuated out of that chamber than less what is found at one atmosphere. This occurs before “perfect vacuum”.
There are and even in normal atmospheric conditions it still offers a displacement of it by an object placed into it.
Understand this.
And also understand that the object will be squeezed down against a much less resistant atmosphere within that chamber.
So, as I said, pay attention to denpressure before you argue against it.
Because you have no clue about it and it's clear.
What has what to do with, as pressure is reduced less and less than atmospheric a feather falls faster and faster as air resistance becomes negligible. Which completely contradicts sense pressure delusion. As pressure is reduced less that atmospheric pressure in den pressure delusion, objects like a feather should fall slower.
So you are down to three things.
One. You ignore what is an actually posted.
Two. You lie about what is actually posted.
Three. You ignore demonstrable reality.
Ok, I've looked through where I left off and there doesn't seem to be much except the you tube experiments that starman put out. All the rest are just little digs and not worth a reply, so I'll concentrate on those youtube videos of starman.
Firstly, I've never mentioned anything floating in any evacuated chamber. If you find that I have, I will accept that I'm wrong and you are right. If you cannot find anything then you are simply making stuff up to keep hold on to fake gravity for some strange reason. Ok back to the experiments.
In the first clip with the two balls and feather, they are in a EVACUATION chamber. It still has pressure but very little resistance to the feather due to the molecules being EXPANDED, meaning the mass of the feather can easily push through the friction under it because it is weak.
As I said before but people didn't listen. The feather or a ball or wood, all originates from being pushed UP from the ground and it's natural break down is back to where it came from, because the matter inside is greater than the atmosphere it is under. No gravity, just a cycle of dense materials being pushed up all the time and being pushed against what is above it, for example: the matter in the atmosphere. No gravity involved and no floating.
The moon experiment is laughable and should never ever be put out by science to try to prove anything, because it's just killed off what you were trying to prove in the first place by using that evacuated chamber.
You see, what you lot failed to grasp, is that the chamber on Earth is subject to FULL gravity as you lot bang on about...yet your moon is subject to ONE SIXTH of Earth's gravity and guess what we see when both experiments are performed?
We see the same drop. It makes no odds though because gravity is 100% made up and cannot be explained as to what it is, yet it's gripped onto like a mouse caught in an Eagles claw.
I'm well aware that your gravity is hard to disprove. There's a simple reason for that. It's because it's like the invisible man; you can't see him, you can't feel him... but you're told he's all around you and to accept it because it's true.
No gravity, just a element stack of dense to less dense molecules/matter/particles all pushing against each other from top to bottom and bottom to top. Action and reaction in equal measures.
So. You expect people to go back to 2014?
This is how stupid den pressure delusion is. You claim molecules with mass expand to take up all space so no space is massless. You claim even in an evacuated chamber the molecules expand so there is no free space. Every bit of volume in the chamber is filled with mass / matter. With no space between the molecules. No space between matter. Is that a false statement.
A feather has mass / matter.
In your delusion for a feather to fall, the mass/matter of the father must occupy the same space filled with the mass/matter of air molecules. Your delusion literally requires the matter of the feather and the matter of air molecules to simultaneously occupy the same space in the same instance for the feather to fall.
