It’s Saturday … time to resurrect a DM gnome! The Sterile Neutrino!

Indian Institute of Technology Guwahati researchers have found distinctive similarities between the nature of dark matter and neutrinos.

… snip …

In fact, the present work of the team shows that the lightest right-handed or sterile neutrino, provided it exists as a part of a popular neutrino mass generation mechanism, having a mass of order a kilo to a mega electron-volts can be the dark matter candidate.
LOL! This isn’t new. Back in the 90s there were already scientific articles saying that sterile neutrinos could be dark matter. And this new article admits that “attempts have been made in the past to also use such sterile neutrinos as dark matter; however, those are currently under severe constraints from the non-observance of X-ray signals and cannot satisfy the observed dark matter density due to the difficulty associated with their production in the early Universe.” It’s not clear from the article how these Indian *scientists* think we can get around those constraints. They just say we can examine this regurgitated possibility in “future experiments”. When all is said and done, this article just seems to be Indian DM scientists performing their #1 job … keeping hope alive and public money flowing. I suspect Indian scientists have mortgages and children to educate, too.

By the way, my *favorite* WOKE astrophysicist, Chanda Prescod-Weinstein, has recently weighed in on this topic too. She wrote (https://www.newscientist.com/article/mg ... find-them/ ) “Sterile neutrinos could explain dark matter – if we can find them”. There's the rub. Then she admits that “searches have so far come up empty” and concludes that “even if nothing turns up once we have explored every place this hypothetical particle could be hiding, that will still be valuable. If sterile neutrinos turn out to only be a figment of the particle theorist’s imagination, we will know it is time to move on.” And she’s right. Mainstream astrophysicists will win any way this turns out because their mortgages will have been paid a little longer and there’s always a new gnome around the corner. ;)

@BeAChooser Speak of the Devil...

In 1999 Mysterious Finger-Like Features Were Spotted on the Sun – Now Scientists Have an Explanation

I'll just bet they do.

https://scitechdaily.com/in-1999-myster ... planation/

From the article:
In January 1999, scientists observed mysterious motions within a solar flare.

Unlike typical flares that showed bright energy erupting outwards from the Sun, this solar flare also displayed a downward flow of motion, as if material was falling back towards the Sun. Described as “downward-moving dark voids,” astronomers wondered what exactly they were seeing.

Now, in a study published today (January 27, 2022) in Nature Astronomy, astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) offer a new explanation for the poorly understood downflows, now referred to as supra-arcade downflows (SADs) by the scientific community.

“We wanted to know how these structures occur,” says lead author and CfA astronomer Chengcai Shen, who describes the structures as “dark finger-like features.” “What’s driving them and are they truly tied to magnetic reconnection?”

Scientists have assumed that SADs are tied to magnetic reconnection since their discovery in the 90s. The process occurs when magnetic fields break, releasing fast moving and extremely energetic radiation, and then reform.

“On the Sun, what happens is you have a lot of magnetic fields that are pointing in all different directions. Eventually the magnetic fields are pushed together to the point where they reconfigure and release a lot of energy in the form of a solar flare,” says study co-author and CfA astronomer Kathy Reeves.

Reeves adds, “It’s like stretching out a rubber band and snipping it in the middle. It’s stressed and stretched thin, so it’s going to snap back.”

Scientists assumed the dark downflows were signs of the broken magnetic fields “snapping back” to the Sun after a solar flare eruption.

But there was a catch.

Most of the downflows observed by scientists are “puzzlingly slow,” says co-author Bin Chen, an astronomer at the New Jersey Institute of Technology.

Shen explains, “This is not predicted by classic reconnection models, which show the downflows should be much quicker. It’s a conflict that requires some other explanation.”

<snip>

The results show that most SADs are not generated by magnetic reconnection after all. Instead, they form on their own in the turbulent environment and are the result of two fluids with different densities interacting.

Reeves says scientists are essentially seeing the same thing that happens when water and oil are mixed together: the two different fluid densities are unstable and ultimately separate.

“Those dark, finger-like voids are actually an absence of plasma. The density is much lower there than the surrounding plasma,” Reeves says.
Well. I'm glad that's settled.

Here's the original paper from 2000 that claimed the features were signs of magnetic reconnection.

https://www.sciencedaily.com/releases/2 ... 233737.htm
BOZEMAN, MT -- A decades-old mystery about the behavior of magnetic fields in solar flares may now be solved, thanks to careful observations by a pair of solar scientists.

David McKenzie, a research scientist at Montana State University-Bozeman, and Hugh Hudson of the Institute of Space and Astronautical Science in Japan, have sighted solar magnetic fields snapping back to the sun, like stretched rubber bands, during the energy release of solar flares.

This behavior, called magnetic field line shrinkage or reconnection outflow, was predicted nearly 30 years ago but never directly observed.
So I guess this latest paper means that this "predicted" (by the mainstream) behavior is STILL not been directly observed. ;)

I applaud Chengcai Shen, Bin Chen, Katharine K. Reeves, Sijie Yu, Vanessa Polito and Xiaoyan Xie , the researchers in the study you cited. They didn't just sweep the "snap back" speed discrepancy under the rug like so many other astrophysicists probably did. Sweeping or ignoring discrepancies has become such a part of modern astrophysics, their behavior is a welcome surprise. They investigated and finally made a REAL contribution to understanding the sun .. by debunking one of pillars supporting the magnetic reconnection myth. Hope they continue such good scientific work.

@BeAChooser How would you interpret “Those dark, finger-like voids are actually an absence of plasma. The density is much lower there than the surrounding plasma,” and the oil and water analogy in light of EU theory?

Well, obviously, the authors weren't thinking about electromagnetic effects on plasmas when they wrote that, and in congratulating them, I wasn't suggesting they were in our EU camp or that their debunking of a supposed proof of magnetic reconnection was deliberate on their part. As for my interpretation ... perhaps the fingers indicate the presence of double layers (Langmuir plasma sheaths)? Certainly some electromagnetic phenomena.

Oh Darn … there's really bad news for the Sterile Neutrinos are Dark Matter gnomists …

Nuclear reactor experiment rules out one dark matter hope

It was an anomaly detected in the storm of a nuclear reactor so puzzling that physicists hoped it would shine a light on dark matter, one of the universe's greatest mysteries.

However new research has definitively ruled out that this strange measurement signalled the existence of a "sterile neutrino", a hypothetical particle that has long eluded scientists.
