I wonder if Hannes Alfven is rolling over in his grave.Simulations reveal black holes inherit magnetic fields from parent stars
Co-author of this study, Ore Gottlieb, is quoted in the article saying …
Now I distinctly recall Alfven making the point that magnetic field lines ARE NOT REAL, a view widely held by the EU/Plasma Cosmology community. As this 2020 Thunderbolts article (https://www.thunderbolts.info/wp/2020/1 ... agination/) states, “Talking about electromagnetic fields as if they are 'things' that can twist and tangle, or become trapped, is a failure to understand what electromagnetism is and how it is expressed. There are no magnetic field lines. Electromagnetic fields exist as continua, without discrete domains. What astronomers reify to create their theories are schematic representations that plot those fields. They are no more real in space than lines of latitude or longitude are on the surface of the Earth.”"What had been thought to be the case is that the magnetic fields of collapsing stars are collapsing into the black hole," says Gottlieb. "During this collapse, these magnetic field lines are made stronger as they are compressed, so the density of the magnetic fields becomes higher."
Now, interestingly enough, the authors’ belief in “magnetic field lines” causes trouble in their research. They admit …
To solve this problem, they invoked what they claim is the black hole’s parent … a neutron star, which is another gnome. And of course, gnomes can be made to do anything they want so … walla … problem solved ...The problem with that explanation was that strong magnetism in the star causes the star to lose its rotation. And without rapid rotation, a newborn black hole can't form an accretion disk—the flow of gas, plasma, dust and particles around a black hole—and could not produce the jets and gamma ray bursts we've observed.
"It appears to be mutually exclusive," says Gottlieb. "You need two things for jets to form: a strong magnetic field and an accretion disk. But a magnetic field acquired by such compression won't form an accretion disk, and if you reduce the magnetism to the point where the disk can form, then it's not strong enough to produce the jets."
And as always, I conclude my posts with the question … of what possible use is this research to those actually paying for it? NONE, into the foreseeable future at least. These research projects are like black holes sucking up taxpayer dollars with not even jets escaping. Just saying ..."And so, the idea is that maybe an accretion disk can save [BAC - inherit] the magnetic field of the neutron star. This way, a black hole will form with the same magnetic field lines that threaded the neutron star."
