Also, a lot lately in this thread is kind of around how den pressure works as, let's say, a replacement for gravity on a flat earth, simply as that. But after reading Jane's compendium on the subject, there's a whole lot more that is required: The dome, the way the sun heats and cools it due to proximity and causes it to breathe, the heat source at the north pole and crystal that projects the stars, seemingly all of which play into the hypothesis. Can den pressure stand on it's own without these other aspects, or are they necessary for understanding it by taking them into account? If the latter, I can see why this is 75 pages.
It can stand on its own and as part of it all.
The major issue is to get the basics in so people understand the extreme simplicity first that leads to what we perceive around us.

Just so I understand, a seemingly super basic question, but am not sure based upon your answer. Den pressure requires a domed flat earth and it wouldn't work on a globe earth?
Denpressure absolutely 1 trillion % and then some...will never work on  a global earth like the one we're coaxed into believing.
We know the earth is a globe from measured distances, satellite angles, angle of the sun. All easily proven.
Good for you, you stick to that and I'll stick to my stuff.

That doesn't answer the question completely. I'll ask it another way, does den pressure require a dome?

Absolutely.
The dome is natural by stack. It doesn't just appear for atmosphere, it is the end tack of the build up of atmosphere which creates the atmospheric pressure around us all and every other object pushing into it.
This is why the dome is helium ice and other elements that build up to it that are broken into their parts by expansion from bottom to top.

It has to have a foundation and the Earth provides it as a solid at the edges, creating the  necessary sloped build  alla round as the major foundation for the actual dome we see reflections off of...not into.

However, this requires much more explanation and will literally skew understanding of denpressure if it's allowed to go too far down that rabbit hole.

No, no, I think it provides a crucial element. Yes, it does serve up other rabbit holes, but if necessary, should be included. It shouldn't skew Den pressure because it's a vital component of the hypothesis. Without it, den pressure doesn't work. Unfortunately for you, that means you have to defend dome theory too, but so be it. It's part and parcel to Den pressure, but hopefully all can discuss as a package.

Balloons expand because of the pressure differential between outside and inside. This is a force on the wall acting against the elastic properties of the rubber trying to pull it back to it's nominal shape.  If you were inside the balloon you would not be "pinned to the edge".  The air would just flow around you as it equalizes.  The force only applies to the wall because it's an continuous barrier that prevents the air going anywhere else.  Try inflating a balloon with a hole in it and see how far you get.
So, the force applies to the wall but magically avoids the thing right next to the wall? Sure, high pressure heads towards low, inflate a balloon with a hole and it's all going to be rushing towards that hole, but without that there is still a force acting on you. It'd be a bit more than just the wind going by you given that it's demonstrably stronger, like you pointed out that's the whole reason a balloon inflates.

Once you've tied it off and stopped inflating, sure, then it's just air going around and nothing would keep you pinned, but there is an active, constant force on you during the process of inflation and I genuinely cannot see how anyone could deny that with a straight face.

Seriously. Stop arguing for the sake of arguing.

Woah, that escalated quickly. My intent was not gish galloping. Though a lovely phrase, I have to work more into my daily conversation. That aside. Look at the logic:

- Den pressure requires a dome
- We talk about den pressure without a dome
- Hence, we should be talking about Den pressure with a dome

The dome is required for Den pressure to exist. How is that "overwhelming an opponent with as many arguments as possible, without regard for accuracy or strength of the arguments." (Yeah, I had to look up gish galloping)

Why won't you answer my question, which came first, but demand I answer yours?
Because you're trying to skew the basics which was my intention and here I am having to deal with Cavendish and so called gravity.

OK, "deal with Cavendish and so called gravity"!


       



If you call it "Cavendish and so-called gravity" how do you explain the 61 sets of measurements (on the left) from 1798 to 2000 that give close to the currently accepted value.

Even the very first, by Henry Cavendish himself,
      gave the value of G = 6.74 x 10-11 m3 kg-1 s-2
      compared to the ‎CODATA Value of G = 6.674 x 10-11 m3 kg-1 s-2.
Not too bad for 220 years ago.

So, if the result of Henry Cavendish's experiment was just "due to a gust of air" how is it that all the others are so close?

Can you show any denpressure experiments that gave comparable accuracy results?

You said a whole lot that goes into your explanations of why you think things happen they way they happen, but I want to exclude that from the discussion for the time being.

Question: does 1cm cube of steel weigh more in air or at the bottom of a pool?

He says the steel is porous and contains air itself.
Which we know by chemical reactions to be false.
Theres a whole science behind metalurgy.

It doesn't take much thought to understand that it is actually porous and so is just about everything solid.

It's also about trapped atmosphere.

Your definiton of porous or the scientific society's?

No ons arguing for the sake of aruing except you.
Denpressure sits alone with only you and scept as champions.
We can deny it with a straight face because it is wrong on so many levels.

Scepti recently stated two things regarding his super simple theory.
1.  Explaining denP would require confusing denp and take us further down his fantasy of a rabbit hole.

2.  We are pressed tot eh "foundation" because aur presses or stacks or expands or whtever in alldirections.
And There is a dome!
So lets combine these two thoughts.
At some point in the middle of our balloon bubble, we will get pushed or energized or forced or whatever he calls it to the edge or foundation or boundary or helium ice.
So at some point an airplane would accellerate OUT despite other FErs stating the magnetic north pulls us IN to the center.

Actually 3 things.
I think scept denounced that things fall at 9.81.
Forget 1 and 2.
Admit or refute things fall at 9.81

Not magically.  You’re sounding more like a real flat earther all the time.  The balloon inflates because of the difference in pressure between outside and inside.  Inside, this pressure difference is not present, so an object inside will not experience this force. 

Air flows to fill low pressure spaces incredibly quickly if not restricted.  Inside a roughly spherical closed space like a balloon, it’s to all intents and purposes instant.  You can take a hour putting air in a balloon and it inflates just as well as if you do it in two seconds.  So your claim is demonstrably false.

I’m not arguing for the sake of it.  I’m arguing because everything I learned in school and university plus years of practical mechanical design experience (including lots of air and gas systems) tells me you are wrong.

I didn’t say you believed in Den Pressure, but you have been arguing that it should work on its own terms as a possible gravity replacement.  My original comment on this thread wasn’t even about gravity at all.  It’s that it would also screw up what we know about gas pressure and the implications for all the technology based on it which manages to work somehow.  Others have made similar entirely reasonable points, including examples of where this theory doesn’t work.

Funny thing is you’ve spent much of this thread telling others we should try to understand Den Pressure before dismissing it.  Maybe you should try to understand fluid mechanics before accusing others of lying?

Measure the time it takes an object to fall 1m. Do you agree a piece of lead and one of copper will fall at the same speed?
From 1 metre, most likely. That proves nothing about gravity.

If I change the shape of one and drop them from a height, one will fall faster than the other.
What happens then?
It gets called out as air resistance.

The it comes down to the nonsense of big so called vacuum chambers and the dropping of objects as some kind of proof. It's complete nonsense.
Do you agree that the acceleration varies at different places slightly and is not related to armospheric pressure?
No, not at all.
The rate of fall or the weight of an object does not depend on atmospheric pressure.  Otherwise a 1kg bag of sugar would vary.

Why do you think balloons expand when you inflate them? It's not because the force is balanced in all directions, because it could be going in any direction, it's because there is excessive force against the edges. If you are against that edge, you will be pinned to that edge. You're 'pressed in one direction' because the force isn't at equilibrium, you have to be pressed somewhere, and that's obvious going to be an edge. If you start off against the metal surface, are you seriously going to tell me the force wouldn't pin you to it?
No, this is completely wrong. 

As the 'Circus Big Top in Space' fills with gas it will diffuse and air pressure will be equal (give or take) throughout.  Nothing will pin you anywhere. 

A scientifically educated person like yourself coming out with this stuff just makes me think laughing behind your hand at us as we even bother to engage with such obvious nonsense.

The dome is required for Den pressure to exist. How is that "overwhelming an opponent with as many arguments as possible, without regard for accuracy or strength of the arguments." (Yeah, I had to look up gish galloping)
Because it's focusing on a different aspect. Yes, denpressure needs a dome, but if you leap to the intricacies of that before you understand how the rest of it works than you're just making it certain you're going to go back to the first topic when you remember less of it and ask the same questions all over.

Not magically.  You’re sounding more like a real flat earther all the time.  The balloon inflates because of the difference in pressure between outside and inside.  Inside, this pressure difference is not present, so an object inside will not experience this force. 
What you are saying fundamentally does not make sense. The outside of a balloon cannot inflate if the inside is not also inflating, and you can't have it growing in size (ie: moving outwards, or accelerating as they were once stationary) without a force. You just can't. We aren't talking about static moments here, we are talking about what happens during the process of inflation and, yes, it's because of a difference in pressure (which easily translates to denpressure) but there is still a force. The time it takes doesn't matter, though obviously the force is greater if you do it faster. Puncture a balloon filled to bursting point and it's much more violent than one that's barely started expanding.

Though it's worth pointing out a balloon isn't where this started. A balloon only got brought up because of a denial of an even more basic principle, the actual chamber in question was a metal disc with rubber stretched over the top. In a regular balloon, thanks to the shape of it, things'd only get pinned to the point opposite the inflation. That chamber has a whole surface for things to push against.

Quote
I didn’t say you believed in Den Pressure, but you have been arguing that it should work on its own terms as a possible gravity replacement.
No. I'm saying you shouldn't argue against the aspects of it that do make sense just because a FEer said them. When you mix in good arguments with bad, you ruin your own credibility for those that disagree with you, and misinform those that do agree on underlying physics.

Why do you think balloons expand when you inflate them? It's not because the force is balanced in all directions, because it could be going in any direction, it's because there is excessive force against the edges. If you are against that edge, you will be pinned to that edge.

Do you see my problem? You have to actively ignore what I say in order to defend your position. Yes, it will diffuse, the air pressure will be equal throughout, but we aren't at that stage yet. I explicitly pointed that out. I'm not laughing, I'm banging my head on the wall.

If you are inside a chamber while it is being inflated, you aren't going to remain perfectly stationary with air in balance all around you. If you seriously think that I don't know what I could possibly say to explain anything to you.

I think the only reason Jane defends these theories is because she researched and wrote topics on them.  If the theory is completely obliterated and defeat is accepted, all the work she has done would have been a colossal waste of time.
You are fundamentally misunderstanding the purpose of the compendium. I wrote it because a) it's fun, b) it should help people make informed arguments to refute theories rather than repeating tired old nonsense that *gasp* the FEers responsible for said theories thought of years and years ago and made sure they could answer. Being purposefully dense does not help anyone except your ego.
You can only 'obliterate' a theory if you know the slightest thing about it. Actively refusing to get informed just makes you look like an idiot.

Or better yet, take me through the physics of how one would be "pinned" to floor whilst the big top is inflating.  All you keep doing is saying "surely you must see it" whilst waving your hands around and offering no explanation whatsoever.

By which you mean repeated explanations you conveniently cut out of your posts?

The air has to go somewhere. Where do you think pressure imbalances go in a sealed vessel, before it has reached equilibrium? Instead of outright ignoring that, think about it. Imagine being in the vessel. Is the wind rushing all around you going to magically move through the floor to push you away from it, or will it just be the natural reaction force of the floor itself? Any inflation of the vessel, each injection of air is going to expand outwards and rush through it in its quest to reach equilibrium, and going to come slamming right into you at the edge by necessity before it reaches that point. It is not going to be able to get behind you to balance that force before it has even reached you.

How much more explanation do you need?!

Not magically.  You’re sounding more like a real flat earther all the time.  The balloon inflates because of the difference in pressure between outside and inside.  Inside, this pressure difference is not present, so an object inside will not experience this force. 
What you are saying fundamentally does not make sense. The outside of a balloon cannot inflate if the inside is not also inflating, and you can't have it growing in size (ie: moving outwards, or accelerating as they were once stationary) without a force. You just can't. We aren't talking about static moments here, we are talking about what happens during the process of inflation and, yes, it's because of a difference in pressure (which easily translates to denpressure) but there is still a force. The time it takes doesn't matter, though obviously the force is greater if you do it faster. Puncture a balloon filled to bursting point and it's much more violent than one that's barely started expanding.

I’ll try again, but I’ve already said this as simply as I know how.

The wall of the balloon expands because of the pressure difference between the inside and outside of the wall.  Obviously the inside of the wall expands.

This answers your initial question (“why do you think a balloon inflates?”).

An object on the inside does not have this pressure differential.  There will be temporary pressure differences as air is pumped in, but it will flow around the object. 

The only force on the object will be like wind.  The object could potentially be blown towards the side, but it won’t be “pinned”.  The flow inside from rapidly inflating the balloon would be very turbulent and a small object able to be carried by the air is likely to be knocked all over the place.

We know what wind feels like on earth, and it’s very different from gravity.

Though it's worth pointing out a balloon isn't where this started. A balloon only got brought up because of a denial of an even more basic principle, the actual chamber in question was a metal disc with rubber stretched over the top. In a regular balloon, thanks to the shape of it, things'd only get pinned to the point opposite the inflation. That chamber has a whole surface for things to push against.

Not my problem, it’s your example.  If you’re struggling to get this, why try to change to a more complicated example?

I didn’t say you believed in Den Pressure, but you have been arguing that it should work on its own terms as a possible gravity replacement.
No. I'm saying you shouldn't argue against the aspects of it that do make sense just because a FEer said them. When you mix in good arguments with bad, you ruin your own credibility for those that disagree with you, and misinform those that do agree on underlying physics.

Well now I’m arguing with an alleged “round earther”, who apparently doesn’t agree with the underlying physics.

And I’m not misinforming anyone.

Temporary is all that matters, I'm just talking about a moment to demonstrate the principle.
It's not going to flow around an object and never touch it or affect it.

The dome is required for Den pressure to exist. How is that "overwhelming an opponent with as many arguments as possible, without regard for accuracy or strength of the arguments." (Yeah, I had to look up gish galloping)
Because it's focusing on a different aspect. Yes, denpressure needs a dome, but if you leap to the intricacies of that before you understand how the rest of it works than you're just making it certain you're going to go back to the first topic when you remember less of it and ask the same questions all over.

How is it a leap into the 'intricacies'? Den pressure only works inside a dome. Umm, kind of crucial, intrinsic, not a "different aspect." It's like a guy asking the man with a broken leg, "How do you walk?"

Man with a broken leg: "I wear this cast that keeps everything stable and rigid."
Guy: "What are those things leaning against the wall?"
Man with a broken leg: "Oh, those are my crutches, I use them to walk."

Do you see my problem? You have to actively ignore what I say in order to defend your position. Yes, it will diffuse, the air pressure will be equal throughout, but we aren't at that stage yet. I explicitly pointed that out. I'm not laughing, I'm banging my head on the wall.
If bashing your head against a wall knock a little basic physics into, go for it! And I'm told on good authority, me at age two, that "It feels good when you stop ;)!"

The only forces on a person during the inflation of a balloon forces due to air-flow, aerodynamic forces or wind, not due to pressure.

Unless this space is being inflated rapidly these forces will be small and nothing that would pin anything (other than a bit of fluff) to anything.

Pressure is a scalar quantity and cannot the only forces it can apply are due to pressure differences and unless inflation is very rapid those are extremely.

That is why denpressure is such an impossible hypothesis yet some Sceppy claims a lump of iron absorbing an impossible mass of air causes gives it weight.

He still has nothing to cause a downward force so still needs gravitation.


You cannot "stack" a fluid, with of without a dome - end of story, Amen!

More like answering:
"Oh, I use those crutches, hold them in my hands."
"How do your hands work?"

Sure, it's necessary info, required for it all to work, but it's pointless knowledge if you don't understand the rest. If you want an RE analogue, the Sun is vital to the Earth's orbit, but if you want to understand orbits you don't need to know any more than 'it's there.' Sure, asking after composition, properties, nuclear fusions, all valid questions, but you don't need to know all those intricacies to understand the Earth's orbit.

That's the point. You could go on endlessly shifting topics from one area to another via connecting threads, and at the end of the day understand nothing. That's why it's a poor-form tactic, it demonstrates more care about trying to find a flaw than it does trying to understand. Only move on when you've at least reached a basic understanding of where you are, otherwise trying to build on that is pointless.

You literally just acknowledged there would be a force, it's just small in your typical balloon. So long as there is a fill-in for the inflation in the analogy, you get that directional pressure against the surface.

Denpressure has direction. There is something special about the Earth as an edge to the dome.

As I said from the beginning an object inside would be affected by the flow of air from higher to lower pressure. 

Is that anything like the force that keep us on the ground, though?

I’d have thought someone would have noticed the enormous gale of wind pushing us down.  It probably wouldn’t help air travel either.

Questions like what causes wind, and why it differs, as well as what gives lift, are separate. Do you accept that there is a reason for denpressure to push things in a specific direction, towards the ground, yes or no?

There's no point in moving on without an answer to that.

This is what I'm talking about with the dome being intrinsic. Now we have this. How does den pressure have "direction"? Is this the "foundation" thing that's been mentioned? And what is "special" about the earth? Is there yet another "different aspect" that's required for den pressure to work that hasn't been brought up?

How about reading the posts I addressed to others discussing that rather than just asking me to repeat it right after saying it once?
