There's a longstanding concern that the physics of electrical currents in large-scale plasmas (at solar system, interstellar, even intergalactic scales!) and corresponding magnetic fields — in sheets and filaments, which organize spontaneously according to the laws of nature, and involve powerful long-range interactions between them — has not received the attention it should, primarily because during the many decades in which the current "majority mindshare" astrophysics evolved, it was extremely difficult to attempt to model/test those concerns, with respect to both extreme computational complexity (super computers needed) and the fact such interactions don't readily boil down to simple/er models, which are easier for humans to iterate upon.

In effect, many astronomical observations are analyzed through a conceptual lens that reduces cause-effect to gravitation and resulting heat, i.e. something "sparkling in x-rays" must be accounted for by acceleration ultimately caused by gravity, or an explosion resulting from extreme gravity.
