Experiment ideas to prove Denpressure?

understanding that a ping pong ball will not drop the same as an iron ball of equal visual size.

But they do drop at the same rate.



With you not able to state way a steel ball twenty times the density of the ping pong ball isn’t dropping twenty times faster.


With you not able to model when the steel ball should gain the lead, and show your modeling correct by experimenting.

With you showing no correlation between drop rates and densities.

With history showing again and again that objects of different densities and masses accelerate towards earth at 9.8m^2, allowing for accurate modeling and trajectory calculations.

Gravity loses because gravity is fictional.

And yet objects of different densities fall at a rate dictated by gravity, acceleration rates that don’t correlate to densities. 

That's a fallacy.
The balloon proves that.

And gravity can be demonstrated through versions of the Cavendish experiment.

Another fallacy.

And a simple experiment shows air dose not push objects down to make them fall down.

It’s evident by the wake left behind the object, the object is pulled down by a force independent of the air medium.  And not a force from the air medium.

But you can see the effect of any dense mass displacement of the atmosphere by simple evacuation of a plastic bottle or even that tanker rail car and so on and so on.

Are you going to tell me gravity pulls it into a crush?

What’s your stated experiment that allows a person to experience den pressure and not gravity?

ANy experiment shows it. It's just a simple case of people throwing aside gravity and paying attention to what they actually do see.

With history showing again and again that objects of different densities and masses accelerate towards earth at 9.8m^2, allowing for accurate modeling and trajectory calculations.

No they don't.

Because if it’s less dense than the atmosphere, it produces lift to overcome gravity.

Why is the balloon not crushed like a human chest breathing?  Why isn’t the ballon crushed to the ground.

The Cavendish experiment has been improved upon over the decades confirming gravity. Do you have better modeling than gravity the predicts and explains the results.

But you can see the effect of any dense mass displacement of the atmosphere by simple evacuation of a plastic bottle or even that tanker rail car and so on and so on.

Which has nothing to do with a simple experiment shows the ball is not pushed down by the air.  So there is a force of gravity acting on the ball. 
 

Gravity is the force that bunches air molecules together at the earth’s surface to create pressure in the open container that is earth.  If the earth had a dome to make it closed like a gas bottle with no gravity, the gas molecules would bounce of each other until they filled the entire space above earth  to create a uniform density and pressure.

It’s worse for you in DPD (den pressure delusion) in your claim air molecules expand so there is no free space.  They then must by necessity in you model expand until pressure differences are equalized.  Like how gas and density equalize in a gas bottle.  In DPD the air molecules would expand until there is no lower pressure in the upper atmosphere.  In you model, what keeps air molecules from expanding when there is pressure and density differences until the atmosphere would be equalized.

DPD still has no explanation what makes gas molecules overcome their tendency to bounce off each other until they have equal spacing, and bunch up at the earths surface.  It’s because the force of gravity overcomes the tendency and draws them down.


The simple fact a Venturi can mix gasoline and air to the proper ratio in a carburetor for a combination engines shows individual molecules are a fixed size, and there is space between individual gas molecules.  And the space increases as pressure decreases.

In the DPD, gas molecules would expand to eliminate all free space in a carburetor making it impossible for the incoming air to pick up the gasoline, and impossible to mix to the correct ratio for combustion.

Are you going to tell me gravity pulls it into a crush?

Who has done that.


Gravity pulls down.  Lighter than air or wings generate a counter force called lift.  If lift is greater than gravity, an object will gain altitude.


We know pressure and gravity are two different forces.  Or a rocket wouldn’t need to keep center of gravity ahead of center of pressure for stable flight.


With you still having no explanation why a ping pong ball and a steel ball fall at the same rate.  And you still have no explanation why the steel ball being twenty times more dense isn’t falling twenty times faster.


And you still can’t model your false assertions.


And you still have not shown a correlation between the rates at which objects drop and their densities.


Gravity with the force of 9.8 m/s^2 accurately models trajectories.  With you having no way to get the right units with DPD with density and mass to get the time a ball drops from a height of 10 meters. 

ANy experiment shows it. It's just a simple case of people throwing aside gravity and paying attention to what they actually do see.

The fact a steel ball and ping pong ball drop at the same rate disproves DPD.


The fact we can breathe with lungs and carburetors work disproves DPD.


The fact molecular sieves work off molecules having individual fixed sizes for a range of pressures disproves DPD.

The fact feathers fall faster and faster as the density of air decreases below that of one atmosphere disproves DPD.  Where in DPD reduction of pressure should mean less “crushing” force so the feather should fall increasingly slower. 

The fact air density can be so reduced where air resistance becomes negligible so a feather, coin, and bowling ball all fall at the same rate disproved DPD.

The fact you can use gravity to predict the outcome of the Cavendish experiment disproves DPD.


The fact you can drop a ball and have it bounce up converting kinetic energy back to gravity potential energy, and not be “crushed” down preventing bouncing disproves DPD.

The fact you can skip a stone off water and not have it “crushed” down into the water disproves DPD.



The fact you can drop a ball.



And see the ball is not pushed down by air, but pulled through the air disproves the den pressure delusion.

If DP was reality and the air pushes denser objects down, why does smoke which contains soot/ash which is clearly denser than atmosphere rise and able to push through the stacked atmosphere pushing it down.

Simple force pushing the smoke into the atmosphere to compress those layers out of the way until they start to sit within layers and cannot be squeezed back against due to the mass of force ejected into that atmosphere.

Why something mostly air doesn’t fall like something totally solid in air. The same reason a water balloon mostly floats in water.

Because the buoyant force acting on all objects has a greater ratio to the mass / more effective on the balloon than the buoyant force has with most objects that are solid, where the air molecules are pulled down by gravity that allows for an upward buoyant force.  The force of gravity fuels the system.

Now. For you.  How does atmosphere push mercury up in a tube of a barometer?

How is it able to sit on a layer when it's always being crushed?

This is why I ask people to pay full attention to what I'm saying.

The atmosphere is layered and each layer is stacked according to the dense makeup of those layers and their ability to withstand compression against their compression with each wanting to decompress in doing so.

Basically, each layer is pushing and resisting or trying to decompress by compressing the layer above creating a resistance in the layer below as that attempt to decompress against the above, causing that compression results in the molecules needing to use a foundation to enable this, which is the layer below.

I've written it like this for a reason.
So you can spend enough time figuring it out.

Ok, so that's the atmosphere in itself.

Now offer up any dense mass into that atmosphere and you create another massive compressive force of all the molecules surrounding the dense mass forced into that atmospheric stacked layers at that point, creating a compression above and below that varies in force with each layer due to resistance of the many layers trying to decompress.

It means the dense mass offered into the atmospheric stacked layers displaces its own entirety of that dense mass of the atmosphere.

It means the atmosphere is now acting like a spring trying to decompress against the dense mass but it depends on the foundation of the dense mass or the force holding it as to whether that decompressive force can actuate.

The atmosphere is layered and each layer is stacked according to the dense makeup of those layers and their ability to withstand compression against their compression with each wanting to decompress in doing so.

Which means with your expanding molecules and no free space in DPD, lungs and carburetors would  be useless.


How would CO2 get out of the bloodstream and lungs? 

It means the atmosphere is now acting like a spring trying to decompress against the dense mass but it depends on the foundation of the dense mass or the force holding it as to whether that decompressive force can actuate.

The higher you go, the lower the atmosphere is.  Low pressure area can't compress a higher pressure.

Now offer up any dense mass into that atmosphere and you create another massive compressive force of all the molecules surrounding the dense mass forced into that atmospheric stacked layers at that point, creating a compression above and below that varies in force with each layer due to resistance of the many layers trying to decompress.

Again.  Gravity explains why gas molecules that bounce off each other and seek to equalize their space migrate towards the ground.

In DPD wouldn’t the atmosphere equalize to a consistent pressure and density with your expanding gas molecules when encountering reduced pressure, ensuring no free space. There is less pressure above, so your DPD expanding molecules should be expanding upward.  Not downward.  Trying to equalize the pressure and density of the atmosphere.

Why something mostly air doesn’t fall like something totally solid in air. The same reason a water balloon mostly floats in water.

And this is what we're talking about. It's a dense mass structure (balloon) displacing the atmosphere minus the volume of the balloon.
It now comes down to the area just as it does with all dense mass objects in terms of making the area smaller or larger to create less resistance or more resistance to the displacement of atmosphere decompressing against it and its ability to be resisted by the layering below it.

The spring back is determined by the amount of displacement of the object in the stacking system of layers the object takes up.

Because the buoyant force acting on all objects has a greater ratio to the mass / more effective on the balloon than the buoyant force has with most objects that are solid, where the air molecules are pulled down by gravity that allows for an upward buoyant force.  The force of gravity fuels the system.

There is no force of gravity and there never has been or ever will be. It's fictional. It's pretty simply as to what's happening once you get your head around it.

Now. For you.  How does atmosphere push mercury up in a tube of a barometer?

The mercury does its own job by displacing its own dense mass against that atmosphere, causing the atmosphere to compress and obviously react to that by attempting to decompress.

You really need to get to understand the staked layer system and what I've just explained not too long ago.

There is less pressure above, so your DP expanding molecules should be expanding upward.
Not downward.  Trying to equalize the pressure and density of the atmosphere.

Ok you're starting to get somewhere. Now all you have to do is understand the stacking system of layers and the breakdown of molecules within.

No. DPD doesn’t explain anything.


Because it requires low pressure to impossibly compress high pressure.  If DPD was real, the atmosphere would be uniform pressure and density.  Because in your delusion there is no gravity.  Only the springiness of your expanding molecules.

Gravity explains why gas molecules that bounce off each other and try to space themselves equally bunch up at the earths surface.

Sorry.

It works because of the low pressure left in the tube which allows the mercury to be compressed up into that space with a lot less resistance to its liquid mass, meaning the mercury in the bowl that's displacing the atmosphere by its own dense mass can be decompressed against or compressed against depending on the agitation of the atmosphere due to fluctuations with central Earth energy movement (sun).

No vacuums anywhere because they cannot exist.

Why in deb pressure delusion does the springiness of air molecules only work up and down.  In reality there should be a randomness of “pressure” in all directions.

So den pressure there should be no pressure from the randomness of the springiness cancelling out.

That's all that's required. Compression and decompression cause vibration and frequencies of varying dense forces.

They simply don't bounce off each other with free space between them. Nothing would exist if this was the case.

There's never a canceling out. Always action and equal and opposite reaction and nothing else, meaning there can never be a canceling out.

The mercury does it by displacement of atmosphere. I've just explained it a few posts ago. Seriously pay attention to it before your typing fingers go to work.

No it doesn't.

It's impossible for something low pressure to overcome higher pressure, meaning a tank with low pressure will not suck/pull/drag anything in. It's a fallacy.

Gravity is what causes weight and weight to accelerate down.

Gravity is the force that gives directionality to weight.


Air molecules that are actually gas molecules bounce off each other and will spread out / equalize their distance from one another in a closed container like a gas bottle.


In the open top earth, gravity explains what force overrides gas molecules tendency to spread out as far as possible with their random bouncing to bunch up at the earth’s surface.  Gravity gives the directionality of bunching air molecules down to the earth’s surface.


In den pressure delusion, DPD, there is no gravity. No downward force to give directionality.


In DPD delusion where molecules expand, there is nothing that governs they can only expand up/down.  Their motion is random and in DPD, they seek to expand to fill up low pressure.  With no gravity, your expanding molecules would expand towards the path of least resistance.  That means up into lower atmosphere. In your model the molecules would want to expand up into lower atmosphere until pressure is equalized.  Until the potential to expand is gone.

But it’s worse than that for DPD.  Gas molecules if not flowing from high pressure to low pressure bounce around randomly.  That means in the den pressure delusion, there is noting to govern the springiness of your molecules would be only up or down. The springiness would be random and in all directions.


Sorry.  Gravity is the force that drives gas molecules that would normally try to equalize their distance from each other down to the surface of the earth.  Gravity is the force the bunches the atmosphere at earth’s surface and gravity is the force that gives weight the directionality of down towards earth.

Dense mass displaces the atmospheric stacked layering that dense mass is forced into.

Ok.  Draw up how that holds up a column of mercury, and don’t use vacuum.

 They don't just work up and down they work in every way 360 degrees. But it's how they work being the key and this is why you need to pay attention to the stacked layering of the atmosphere.

No.  It’s easy to understand the atmosphere doesn’t work that way…

Don’t think about it.  Answer the question.

Den pressure delusional does not explain how we as humans breathe, nor explains how an carbureted engine takes in air to mix it with fuel to reach the proper mix and ratio for combustion.

Individual molecules of fixed size with space between them explains how in breathing in the smallest of spaces in the lungs CO2 can mix with fresh air and the CO2 be exhaled.

Individual molecules of fixed size with space between them explains how in breathing in the smallest of spaces fresh O2 can make it to the blood stream.

Individual molecules of fixed size with space between them explains how a carburetor and a Venturi can be used to mix gasoline and air in the proper ratios that allow for combustion.  Where if there is not enough air mixed with the gasoline it will flood the engine and not ignite.  Or if there is too much air, and not enough fuel.

DPD, den pressure delusion, where molecules expand and contract to ensure no free space with pressure would just vapor look lungs and carburetors.  There would be no mixing. 

Lungs would just buildup CO2 molecules in the DPD as the molecules would sit there expanding and contracting, taking up all the space.  No room to mix with fresh air in the small passages of the lungs.

Carburetors would bring in expanding air molecules in the DPD taking up all the space in the Venturi allows no room for mixing with fuel.  Especially no room from the mixing of air and fuel required to reach the correct ratios for combustion. 

Lungs and carburetors with expanding and contracting molecules that allow for no free space between molecules would be useless in the den pressure delusion.

Dense mass displaces the atmospheric stacked layering that dense mass is forced into.

Going to explain how a rock skips on water in den pressure delusion?

So.

Back to the skipping of the rock thing.

The original post is below.


But the meat of my argument is this.  In the DPD, den pressure delusion, why would rocks skip on water with the “crushing” force of the atmosphere?

When I think of “crush” I think of a hand driving a ball into a table or water?  Where there is no converting kinetic energy back to potential energy because the “crushing” atmosphere in DPD wouldn’t allow the ball or rock to jump back up into the atmosphere.






 DPD wouldn’t allow for skipping rocks

New thought.  It’s about skipping rocks.  A little of tying old arguments to the new.

How do you distinguish “forces”.

A simple experiment shows the atmosphere doesn’t push down a dropped ball.



By the way the ball moves and creates a wake, it’s obvious the ball is pulled through the atmosphere by gravity.

So the new thought was from skipping rocks.

Gravity pulls down on things.  Over simplification, but let’s go with it for simplicity.

I can skip a rock across water.  The rock and water are both pulled downward.  The water pool not changing potential energy, the rock converting potential energy to kinetic energy.  I guess you could also ask why a dropped ball would bounce in den pressure.

Well, long story short. The rock thrown at the proper angle has a collision with the water, skips off the water.  A process of being thrown, pulled down by gravity as it travels, collisions, and equal and opposite reactions.


A ball has potential energy from being held above the earth and the force of gravity pulling on it.  The ball is released, and in a perfect world hits something hard like a steel plate, bounces up and would return to its starting height.  But will not from friction.  Friction and sound energy created from the collision, and friction with the air.


Video of the skipped rock..



In den pressure delusion.  Hmm how about we just start calling it DPD.  In the den pressure delusion, DPD and the atmosphere supposedly crushing everything to the point it makes you breathe?

Quote from: sceptimatic on June 01, 2023, 02:53:15 AM

You create a low pressure to allow higher pressure to enter your lungs and your lungs expand to fill the low pressure within your cavity which expands with your lungs to compress the external atmosphere which then compresses back to crush your chest back and also your lungs to expel the circulated gases back to the atmosphere and off we go again.

I still think if den pressure was true you should be able to make someone breathe by spinning then head over heels.

Anyway.

Why would a rock skip in the DPD?  Would it create a different effect on skipping rocks.  The “atmosphere” is supposedly crushing everything down into the “ground”?  The rock is more dense than the water.  Why wouldn’t the water just be an extension of DPD and keep crushing the rock down as an extension of the atmosphere?

How would potential energy work in den-pressure delusion, DPD? 

Or maybe it’s more of the aspect the atmosphere is a force crushing things down in DPD (den pressure delusion) and isn’t a median to be skipped off of? 

There is no downward force.  Only somehow a “crushing” force from low pressure to high pressure that contradicts the words of its own creator? 

Quote from: sceptimatic on May 31, 2023, 03:14:25 AM

It's impossible for something low pressure to overcome higher pressure, meaning a tank with low pressure will not suck/pull/drag anything in. It's a fallacy.

So why would the atmosphere be a “crushing force” and why wouldn’t the water be an extension of the “crushing force” instead in reality being a media to skip a rock off of?

Other things ignored.

Which has nothing to do with a simple experiment shows the ball is not pushed down by the air.  So there is a force of gravity acting on the ball. 
 

Gravity is the force that bunches air molecules together at the earth’s surface to create pressure in the open container that is earth.  If the earth had a dome to make it closed like a gas bottle with no gravity, the gas molecules would bounce of each other until they filled the entire space above earth  to create a uniform density and pressure.

It’s worse for you in DPD (den pressure delusion) in your claim air molecules expand so there is no free space.  They then must by necessity in you model expand until pressure differences are equalized.  Like how gas and density equalize in a gas bottle.  In DPD the air molecules would expand until there is no lower pressure in the upper atmosphere.  In you model, what keeps air molecules from expanding when there is pressure and density differences until the atmosphere would be equalized.

DPD still has no explanation what makes gas molecules overcome their tendency to bounce off each other until they have equal spacing, and bunch up at the earths surface.  It’s because the force of gravity overcomes the tendency and draws them down.


The simple fact a Venturi can mix gasoline and air to the proper ratio in a carburetor for a combination engines shows individual molecules are a fixed size, and there is space between individual gas molecules.  And the space increases as pressure decreases.

In the DPD, gas molecules would expand to eliminate all free space in a carburetor making it impossible for the incoming air to pick up the gasoline, and impossible to mix to the correct ratio for combustion.

Are you going to tell me gravity pulls it into a crush?

The fact feathers fall faster and faster as the density of air decreases below that of one atmosphere disproves DPD.  Where in DPD reduction of pressure should mean less “crushing” force so the feather should fall increasingly slower. 

The fact air density can be so reduced where air resistance becomes negligible so a feather, coin, and bowling ball all fall at the same rate disproved DPD.

The fact you can drop a ball and have it bounce up converting kinetic energy back to gravity potential energy, and not be “crushed” down preventing bouncing disproves DPD.

The fact you can skip a stone off water and not have it “crushed” down into the water disproves DPD.



The fact you can drop a ball.



And see the ball is not pushed down by air, but pulled through the air disproves the den pressure delusion.
