New Mainstream Simulation Of Black Hole Jets

The black hole in M87 shoots a relativistic jet, or a plasma jet, outwards at close to the speed of light. In a new study, an international team of researchers have gleaned new insights about the black hole and its jet by modeling it in incredible detail with computers.
Ooookay.
The team used three-dimensional supercomputer simulations to model the region of the M87 black hole and its accretion disk, a disk of gas, plasma and various particles that surrounds and feeds a black hole. They took into account temperatures, matter densities and magnetic fields that are likely to exist with this black hole based on existing observations. 
Notice the “that are likely to exist” bit?

In other words, maybe they tweaked a bunch of assumptions to get the desired result?

They later admit this …
questions still remain about how such a powerful relativistic jet comes to be and how it remains stable, shooting across immense distances in space.
Perhaps questions remain because they don’t really have a clue how the magnetic fields they ASSUMED exist came to be or how electromagnetism actually affects plasma. Perhaps because they are using magnetic reconnection in a ways that Hannes Alfven, were he still alive, would view with skepticism … because he called magnetic reconnection pseudoscience ... a "pseudo-pedagogical concept" that "makes you believe that you understand a phenomenon whereas in reality you have drastically misunderstood it."

And note this final concession in the article …
Rezzolla said “While there is still room for alternative explanations …”
I don’t think he really means that, because an alternative explanation has existed for decades and decades and the mainstream has steadfastly refused to even consider or discuss it. They can’t, because if they did, the outcome of that *debate* might threaten the money pipeline they’ve all grown dependent on for new homes, vacations, children’s educations, etc the past many decades and decades.

Just saying ...
