>Galactic filaments are the largest known structures in the universe, consisting of massive, thread-like formations of galaxies and dark matter that connect galaxy clusters. They form the cosmic web and can reach lengths of hundreds of millions of light-years.

>Cosmic filaments can spin. Astronomers have discovered that these colossal bridges of galaxies and dark matter, which stretch for hundreds of millions of light-years, possess angular momentum and rotate as coherent structures.

>Birkeland currents (electric currents that follow magnetic field lines in space) are intrinsically linked to plasma. Because plasma is a highly conductive state of matter made of freely moving charged particles (ions and electrons), it both carries and is heavily influenced by these currents.

>Birkeland currents can also twist, producing a helical pinch that spirals like a twisted or braided rope

>Pairs of parallel Birkeland currents will also interact due to Ampère's force law: parallel Birkeland currents moving in the same direction will attract each other with an electromagnetic force inversely proportional to their distance apart whilst parallel Birkeland currents moving in opposite directions will repel each other.

A system that is ~100% plasma should be modeled with plasma physics. Shocking.

Science is not real, shitentists make up science fiction in order to receive some shekels

A discovery which was predicted by dark matter simulations. It was literally this result which inspired the observational study.

Can you show me a simulation where these currents produce the structure of the cosmic web? Nope.
It is just a supposition by electric universe proponents that it will magically work. But there is absolutely zero evidence or serious theory to show it is feasible.
And where are these giant electric currents coming from? There is no evidence that these filaments carry current, the magnetic fields are small.

>A system that is ~100% plasma should be modeled with plasma physics. Shocking.
Modern simulations do use MHD. The problem isn't the physics considered, it's that the electric universe crowd have a totally different cosmology in mind, which has to be specified and defined to be tested. They are completely disinterested in actual physics and science. And would rather imagine how they think the universe should work, and just assume they are correct. In real science you have to see if physics allows it, do simulations and calculations, and then try to test it against real data.

they can't come out and publicly say
"Yeah so it's just another constant to make the math work like it has in the past"
That hurts perception, which hurts funding, which hurts the speed of figuring out just what in the fuck it is that we aren't seeing.

i humbly submit this teleological explanation of filaments and other cosmological macro-structures from a non-science schizo (who keeps making qualitative predictions of future JWST observations and being right), making no claims to its veracity.
note that this whole study is orthogonal to the mechanistic science of the functioning of cosmological objects, neither validating nor invalidating any particular model.
mainstream science is doing biochemistry on the universe, while this guy is doing evolutionary biology. pretty fascinating stuff

It isn't really an explanation of anything. It's a very vague set of ideas.

The biggest gap is that he does not demonstrate model can even form the cosmic web which looks anything like the real universe. Standard cosmology can, and has been compared to the real data. Can realistic AGN jets gets really produce voids? To demonstrate that you need to run a simulation or a calculation. They author naively rejects simulations as useless, but he included dark matter simulations as his only image of what the cosmic web looks like. Without this it's just a random guess. People have made up alternative cosmologies in the past which couldn't even form galaxies, you don't know until you actually sit down and calculate. You cannot just guess how the universe works, especially when you are not even a physicist.

It's just wild guesswork and supposition. Combined with lots of ignorant statements about dark matter. But in the end his model cannot explain any of the pillars of evidence for dark matter. He also never mentions actual cosmology, and the expanding universe, remove dark matter, and you change everything, the age of the universe, distances, geometry... And he has no concrete predictions because nothing is quantitative. His own guesses are not the same as actual predictions of a model. He doesn't have a model.

Also, he wrote this shit with an LLM. It's slop.
