Interesting thought.

Nah... you're just thinking of climate science, political science, sociology and psychology.

The real sciences are still ok.

The dark matter hypothesis goes back much further than Oort, by 50 years or so, to explain the stability of galaxies that are rotating too fast to be accounted for by the gravitation of the visible matter they contain.

As such, it is hardly a foundational principle of all astronomy (like, say, Newton's law of gravitation), and a Nobel prize awaits anyone who can prove that the "extra" gravity in the rapidly rotating galaxies comes from conventional matter. Similarly, a Nobel prize awaits anyone who can directly observe dark matter. Until one or the other happens, dark matter remains a hypothesis.

Reference?

I rather doubt that these physicists were able to prove the hypothesis that something other than gravity was involved, but I'd be happy to read about it.

I just got through saying I'd be happy to read their proof, if such proof exists. I merely said I had doubts, but I'm willing to be convinced otherwise with sufficient proof.

How did you find out about it, if not from a reference?

@2733812

What I was looking for was the "proof" you said existed for non-gravitational effects that eliminate the need for the dark matter hypothesis.

It seems that there have been several attempts, beginning with Alfvén, to introduce electromagnetic forces on a galactic scale. Unfortunately for these models, they make many predictions that run counter to observations, hence the plasma universe model is not accepted.

https://en.wikipedia.org/wiki/Plasma_cosmology

Recently, a hypothesis of scale invariance that the author says may obviate the need for dark matter/energy has been published. It will have its day in court, but again nothing has as yet been proved by it.

The first reference I gave indeed cites failures of the plasma model.

"Some of the places where plasma cosmology supporters are most at odds with standard explanations include the need for their models to have light element production without Big Bang nucleosynthesis, which, in the context of Alfvén–Klein cosmology, has been shown to produce excessive x-rays and gamma rays beyond that observed.[33][34] Plasma cosmology proponents have made further proposals to explain light element abundances, but the attendant issues have not been fully addressed.[35] In 1995 Eric Lerner published his alternative explanation for the cosmic microwave background radiation (CMB).[36] He argued that his model explained the fidelity of the CMB spectrum to that of a black body and the low level of anisotropies found, even while the level of isotropy at 1:105 is not accounted for to that precision by any alternative models. Additionally, the sensitivity and resolution of the measurement of the CMB anisotropies was greatly advanced by WMAP and the Planck satellite and the statistics of the signal were so in line with the predictions of the Big Bang model, that the CMB has been heralded as a major confirmation of the Big Bang model to the detriment of alternatives.[37] The acoustic peaks in the early universe are fit with high accuracy by the predictions of the Big Bang model, and, to date, there has never been an attempt to explain the detailed spectrum of the anisotropies within the framework of plasma cosmology or any other alternative cosmological model."

A scientist who makes theoretical claims indeed has to prove them to the satisfaction of other scientists. Claims are tested experimentally, and if they fail to match experiment, they are rejected. If the plasma model is right, then the Big Bang didn't happen, general relativity is wrong and the sun is not powered by nuclear fusion. Remarkable claims like these require remarkable proofs, which so far have not been forthcoming. On the contrary, they have been DISproved.

This is not to say that the dark matter/energy hypothesis is therefore necessarily correct, but just that the plasma hypothesis is wrong.

No one denies that a charged particle in motion is a current.

What they do deny is that the charged particle flux to the sun is anywhere near large enough to account for the power the sun produces if it were simply a plasma discharge. Why does the Earth only have a feeble aurora borealis if there is all this galactic current flowing? Why isn't Jupiter or Saturn glowing like a small sun?

They know perfectly well that the solar "wind" is an expression for a flow of charged particles from the sun.

Do you also think that when oceanographers speak of water "currents" they mean electric currents?

And I notice that you have conspicuously dodged my questions.

Simply saying it's nonsense doesn't prove it's nonsense.

And now you are skedaddling because you have no proof. biggrin smilie

P.S. Even Velikovsky didn't buy the electric Sun hypothesis.

" Alfred de Grazia reports that Velikovsky never accepted Juergens' [electric Sun] theory, because the thermonuclear theory seemed sound to him.[16] de Grazia writes that he:

"asked Velikovsky, more than once, whether he could accept Juergens' theory, he would reply with a definite negative. He adhered to internal thermo-nuclear fusion as the secret of the Sun's radiation" "

You're skedaddling because I asked questions about the electric Sun hypothesis that you can't answer. If you could, you wouldn't be throwing up these "disrespect" smokescreens.
