Discussion Overview

The discussion revolves around the claim that the universe may not be expanding, challenging established theories such as relativity and the Big Bang theory. Participants explore various perspectives on this claim, including philosophical implications and the validity of scientific consensus.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants reference a website that presents an alternative view on the universe's expansion, suggesting it offers a different perspective.
  • Others argue that the claims made on the website contradict well-established scientific theories, including relativity and quantum mechanics.
  • There is a call for participants to identify specific statements from the alternative view that could be disproven.
  • Concerns are raised about the philosophical basis of the claims, with some suggesting that rejecting common scientific understanding undermines the need for science itself.
  • Participants express skepticism about the alternative view, with one noting a perceived lack of understanding of fundamental physics concepts in the claims presented.
  • Some participants emphasize the importance of questioning established models and being open to alternative explanations, while also critiquing the current state of theoretical physics.
  • There is a discussion about the nature of gravity and other fundamental forces, with differing opinions on whether current descriptions are adequate or merely labels.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the claims regarding the universe not expanding, with multiple competing views presented. The discussion remains unresolved, with no consensus reached on the alternative perspective.

Contextual Notes

Some participants note that the claims made by the alternative view may rely on misunderstandings of established physics, but the specifics of these misunderstandings are not fully explored. There is also mention of the limitations of current theoretical frameworks, such as renormalization.

It is not a law it is an observation.

If a law cannot be derived from a model, then observations in accordance with that law cannot be considered evidence for that model. You can say z-pinching ignites fusion all you want... but if you cannot derive precise numerical results from the basic principles of your theory, then you cannot argue observed results support the model.

You're still at the "Hey, this could be a possibility" stage, not at the "Hey look at me, I got proof this is right" stage.



Can you explain to me how that would constitute a flaw?

Since we've now established that the electric sun model does NOT give a precise numerical prediction of neutrino flux, this part of my argument is irrelevant.


Do you understand the huge difference in the strength of the forces as anything other than a number?

The difference is a number.


Electric charges try very hard to arrange themselves so that net electric charge is zero. A website with no credibility is not going to convince me without proof that this tendency is not only suspended in the interior of the sun... but it happens in just the right amount so that the sun doesn't blow itself apart.

What? The fact has been observed period. What more evidence do you need?

Z-pinching has been observed and there are quantitative exlanations of it. Go learn plasma physics if you want the laws and numbers.

This is not my theory. It is a quantitative and a qualitative theory and if you want the quantitative details then study it more.

Your assumption is incorrect. The precise value comes directly from nuclear science of the fusion going on in the Z-pinch effect. The number has been OBSERVED and quantified and it matches inversly to the sun-spot number. Can the standard model explain that? Not even close.

The difference is a number.

No the difference is a ratio and a huge one at that.

Again demonstrate the flaws in the model instead of quibbling about these banalities.

My studies are currently directed into differential geometry / lie groups with the immediate intention of gaining more than a casual understanding of general relativity.

Anyways, I don't doubt Z-pinching has been observed and there are quantitative explanations of it. I'm doubting that, from there, you can make precise quantitative predictions of things like neutrino flux from the sun.


This is not my theory. It is a quantitative and a qualitative theory and if you want the quantitative details then study it more.

If and when I do, it will be from respectable sources, not crackpot sites.

Which is why cosmologists are considering incorporating plasma physics into their models... NOT throwing away their (mostly successful) theories in an attempt to rewrite everything in terms of plasmas.

The flaw is that it is asserting that charges don't behave the way they usually do, without proof.

If one model easily explains a set of data and the other is at a total loss to explain it what does that say?

Doubt all you want, but your doubt does not constitute an argument.

Your little pidgeon-holes and categories conveniently enable you to escape from learning anything contrary to your faith.

Well that is a start at least, but it amounts to more retro-fitting and cannibalizing of a perfectly coherent and explanitory model.

Please explain that one in more detail.

And how does one go about deriving from the electric sun model that neutrino flux should be inversely proportional to sunspot density?

So?

Those who live in glass houses...

Which has no proof of correctness.


Please explain that one in more detail.

That electric charge tends to organize itself to form neutrally charged structures.

What difference does it make to the theory when the inverse proportionality is observed?

This is another diversionary tactic. You want to know the math go ask a plasma physicist.


So?

lol

are you going to make any arguments about the theory or what?


Which has no proof of correctness.

You have been saying that from before you knew anything about it.

The fact is that it can explain more data than the standard model can so it has more "proof".

I wonder if you are ever going to understand the theory well enough to debate it.

That electric charge tends to organize itself to form neutrally charged structures.

The fact is that the neutrino flux density suggests strongly that the fusion is taking place in the double layer not in the depths of the sun.

The idea that the gravity of the plasma can overwhelm the electrical repulsion is a completely hypothetical concept. We have nerver observed such a process and the data does not support the hypothesis.

Plasma physicists don't appear to endorse the model you describe. For instance, consider this page hosted by the Princeton Plasma Physics Laboratory:

http://fusedweb.pppl.gov/

While we're discussing plasma physics, check out this excerpt from the pppl page at http://www.pppl.gov/projects/pages/magnetic_reconnect.html

Magnetic reconnection is the breaking and topological rearrangement of magnetic field lines in a plasma. It is one of the most fundamental processes of plasma physics and has important relevance to fusion research, as well as to the physics of the Earth's magnetosphere and solar flares. It may also play a key role in heating the plasma in the solar atmosphere, or solar corona.

(I don't remember in which thread you claimed that such notions were nonsensical fancies of astronomers who know nothing about electrodynamics)


And Auburn University cautions strongly about using terrestrial experiments to model interstellar plasmas at http://www.physics.auburn.edu/~plasma/basic/spacelab/simulate.html

(and this site too states that fusion occurs in the core)


The fact is that it can explain more data than the standard model can so it has more "proof".

But can it make precise numerical calculations from initial assumptions?


We have nerver observed such a process and the data does not support the hypothesis.

Sure it does.

Not all of them do of course and I never said that they did. Not all physicists endorse the BBT either. So what?

? what on Earth are you talking about. I never said that those ideas that you quoted are nonsense. If you can find the misinterpreted post of mine let me know.

So what does this have to do with the model I was talking about? Another diversion? Can't debate the Plasma Cosmology model?


But can it make precise numerical calculations from initial assumptions?

Yes indeed it can. You would know this if you dared to actually learn the model.




Sure it does.

go on... explain just how it explains the proportionality with the sun-spots.

I spent half an hour looking for a reputable website that had something similar to the electric sun model. I could find none. Can you point me to one, or am I right in suspecting none exist?

You attempt to gain support from extrapolation from experiments on terrestrial plasmas. Analogy with the properties of terrestrial plasmas is the sole motivation given on the electric-cosmos website.

And where can I find the model?

I'm curious as to how this relates to my assertion that electric charge tends to organize itself to form neutrally charged structures.

So you are giving up on Plasma Cosmology?

What? The sole motivation is to build a more solid understanding of cosmology.

You can't... give up

There is zero evidence that the fusion happens in the core and there is evidence that it happens at the surface.

I was speaking about the motivation to choose that theory amongst the assortment of alternatives.

Oh that is easy. Because it solves the mysteries that the standard model cannot explain... and I suppose I will have to list them again or can you read or even remember?

I remember. And I remember objecting because solving the mystery implies being able to generate precise numerical calculations which your website does not provide.

That website does not provide all the calculations nor does it give the whole of our knowledge of Plasma Physics. Did you really expect it to? How many small introductory websites do you know of that give every bit of quantitative knowledge about a theory?

This is meant to be a qualitative and slightly quantitative overview of the theory not the complete and total content of every single bit of information about the theory.

I believe I have asked you to provide the details; you could have said them yourself or redirected me to a less elementary website.

I believe it was I who first pointed out that the information on that website is just as useless in understanding anything as reading a pop media layperson's book on a mainstream physical theory.

I believe you will have to buy a book for that.

It is a detailed and very adequate introduction to the theory. I figured that was the obvious place to start. I didn't realize that you were ready to devote months or years to the study of Plasma Physics! But good for you! :wink:
