Can Electricity Travel Through Space on Astrophysical Jets? (mdpi.com)
Slashdot reader Chris Reeve writes: An October 2017 paper titled Electric Currents along Astrophysical Jets reports that "Several researchers have reported direct evidence for large scale electric currents along astrophysical jets." A review of the citations at the end of that paper and others (here and here, for instance) would seem to suggest that one of the great Internet science debates has finally been settled: Electricity does indeed travel through space over vast cosmic distances.
What has been interesting to watch about this unexpected development is that science journalists have so far not explicitly reported this as a shift in theory, and commenters on sites like phys.org appear to deny that any change has even occurred: "The jets have been shown not to be electric currents, the energy and the physics involved are certainly not electromagnetic." This comment completely rejecting these new findings was highly rated by other phys.org readers, suggesting that the failure to explicitly report this as a change in theory has left this controversial topic in a highly confused state.
The paper summarizes what it calls "observational evidence for the existence of large scale electric currents and their associated grand design helical magnetic fields in kpc-scale astrophysical jets." And the original submitter details the history of the question in a follow-up comment arguing that at our current moment in time, "a mistaken bias against electricity in space continues to dominate conversations."

Dear Slashdot Community,
Some 11 years ago, I watched a curious thing happen in the comments of a Slashdot article, and it would forever change my life. I watched on as members of the tech community labeled as pseudoscience the simple idea that electricity can travel through space over plasma (and actually do stuff of importance at the largest observable scales). Since that day, I have systematically tracked this electricity in space debate, and I have come to view the reporting on this topic as the greatest science journalism failure of our time.
To review, a plasma is just a gas with some percentage of unbound charged particles. We call it plasma, rather than gas, because it observably behaves differently. With less than even just 1% ionization, the ionospheric gas is observed to respond to electromagnetic fields. In the laboratory, plasmas can form into very complex structures like filaments. These filaments exhibit a long-range attraction and short-range repulsion with one another, which causes them to pair up without combining. Careful inspection of a novelty plasma globe will reveal that the filaments will tend to separate when they come into contact with the glass. The filaments can also link up with one another into very complex networks. All of this complexity is rather remarkable given that we are just talking about the "fourth" state of matter.
Now, let's review the current state of this electricity in space debate as it should be reported by science journalists.
1. It is not widely known, but definitely a fact that proper galactic rotation curves were simulated in the early 80's on government supercomputers by one of the world's leading plasma physicists, without the need for any dark matter. The reason that the arms appear to rotate as almost fixed plates, in this view, is that they are conducting electrical currents.
Galactic expert, Tim Thompson, has claimed that Peratt's decision to publish in IEEE was an attempt to avoid scrutiny. He admitted that no galactic researcher has ever read IEEE and they wouldn't know that the journal even exists (it's the largest technical organization in the world); and Thompson even went so far as to advise that galactic researchers intentionally avoid reading IEEE. You can see an annotated snapshot of his online forum post here.
2. We have been left with the impression that the CMB can only be explained as a remnant of the Big Bang expansion. This is simply not true:
That quote comes from one of the world's leading plasma physicists, Anthony L. Peratt (Physics of the Plasma Universe, Second Edition, 2015, p.33-34.) Peratt would go on to publish a paper revealing more than a hundred local hydrogen filament structures which he claimed correlate with structures in the WMAP cosmic microwave background.
It would seem that people are not yet connecting the dots here between these recent admissions by astrophysicists that large-scale electric currents are real, and this faint microwave fog that is apparently coming at us from all directions. There is, without a doubt, more than one way to explain this cosmic microwave background; but you'd never know this from the science
Yes it is. In the 80 homosexuality was Scientifically acknowledged by Scientific experts to be a disorder. Thanks to a media campaign, we now know Scientifically that homosexuality is completely normal. The same thing could be said about Jews and just about everything else.
Science and truth are definitely up for debate. Reality is subjective. The only thing that is constantly true through different times and cultures is the fact that the people living in the current time and culture are always correct and it is only those other guys that had it wrong.
Thank God we live in the exact time that we do.
Plasma seems to be the quintessential complex system.
https://en.wikipedia.org/wiki/...
"Although the underlying equations governing plasmas are relatively simple, plasma behavior is extraordinarily varied and subtle: the emergence of unexpected behavior from a simple model is a typical feature of a complex system. Such systems lie in some sense on the boundary between ordered and disordered behavior and cannot typically be described either by simple, smooth, mathematical functions, or by pure randomness. The spontaneous formation of interesting spatial features on a wide range of length scales is one manifestation of plasma complexity. The features are interesting, for example, because they are very sharp, spatially intermittent (the distance between features is much larger than the features themselves), or have a fractal form. Many of these features were first studied in the laboratory, and have subsequently been recognized throughout the universe."
homosexuality was Scientifically acknowledged by Scientific experts to be a disorder.
Not to contradict the point you are awkwardly trying to make, but this part is wrong.
Whether or not homosexuality is classified as a disorder, or a benign variation, has little to do with science. Like the medical definition of addiction, it depends on how it affects your life.
If you live in a society where sodomy is frequently punished by death, but you keep doing it, you have an illness.
Societies fault perhaps, but an illness still. Social context can change the medical classification, without any changes in the hard science.
