I imagine the black hole behaves like a supermassive accelerator, and the energy actually escapes as extra-super-massive "elementary particles" which we can't build telescopes big enough to sense, and basically flow through our own bosonic field like bigger waves. (Perhaps we can see them decay-spiraling through the "gas clouds".)

And at various harmonic reaches of these singular mass-energy units, they decay into the more common and stable particles, feeding stars and fuzzing up Magellan.

Another reasoning: When you put quarks together, and put the results together with some leptons, you get more massive things like atoms, molecules, and all "matter". Quarks are stackable. Leptons are cumulative. The Higgs Boson is already very massive, and isn't stable on Earth, but maybe it is stable in the black hole, and can scale to whatever mass the fabric of that energy-space requires.

Personally, I think the black hole ultra-collides quarks and leptons into highest energy "elementary particles", and that energy feeds these bubbles, which can be described as ultimo-massive bosons decaying, into lesser boson and also leptons and quarks, far out away from the black hole. I would not be surprised if one day it was found that astral bodies tended to form along some predictable distances from galactic center; where the bosonic field is decaying very predictably into the stuff that fuels the creation of those same astral bodies.
