However the vacuum itself should have CHIRAL PROPERTIES, to prefer electrons above positrons to survive as single particlkes, in this particle click-on process.
The BH horizon is assumed to be able to repell Fermions by the "SPIN FLIP" of fermions induced by the extreme local structure of the dense oscillating Higgs vacuum lattice called "warped space" or space warping.
CONCLUSION: Fermions (gas and dust) are mainly pushed away from the black hole by the Spin Flip induced by the local vacuum structure of the horizon.
Only the vacuum itself and radiation is able to pass through and feed the black hole.
Ultra large Black holes (BHs) are supposed to be active in the BH splitting Big Bang process, as the origin of the well known acceleration of the gas concentration in Galaxy forming.
Observations of the Early universe are reason to assume that at least TWO pairing BHs are responsible for such an acceleration process in the middle of both BHs.
Such a symmetric double BH configuration is even observed in much smaller objects like star forming Nebula and in the Hartley 2 Comet!
As a consequence I suppose that ALL Black Holes are able to pair and split, not only in the Big Bang or star forming Nebula, but at all other scales down to ball lightning.
Overview of Black Holes in Nature with decreasing order of sizes.
Big Crunch Black Hole. (BCBH)
Big Bang Black Hole (BBBH)
Galaxy Anchor Black Holes (GABHs)
Stellar Anchor Black Holes (SABHs)
Sunspot Black Holes (SUBHs)
Cometary Black Holes (COBHs) also supposed to be active inside "Sungrazers".
Ball Lightning Black Holes (BLBHs)
Fire Ball Black Holes (FIBHs)
Observed at 70-90km Mesosphere. See Langmuir video.
The special features of Cometary Black Holes. (COBHs)
COBHs even come in pairs, see Hartley 2. 2010 (by Cassini spacecraft).
If COBHs hit the sun they are supposed to become Sunspot BHs. (SUBHs).
If COBHs hit planets or even moons they are supposed to be the origin of Red Spots (Jupiter) or a heating effect, like Saturn's moon Enceladus (cracks and jets also observed by Cassini spacecraft 2010).
Even Volcanic activities and the internal heat source of the Earth could be originatd by this process.
Four kinds of NEW black hole creation.
1: I propose Electro magnetic (x-ray) interference to be the origin of the group of small sized black holes. (SUBH-COBH-FIBH-BLBH). This process is observable in the Langmuir video: fireball production inside Sprites by electric discharge activity.
Sunspot black holes are supposed to be the remnants of Comets and so called Sun grazers originated by Solar Electro magnetic discharges.
2: Stellar Anchor Black Holes (SABHs) are supposed to be formed in supernova explosions.
3: Galaxy Anchor Black Holes (GABHs) are supposed to be formed in the initial splitting process of the Big bang black hole (BBBH).
4: the Big Crunch Black Hole is supposed to be the result of the contraction of the universe, due to the elimination of the Dark Energy (Higgs) content of the Universes by Higgs consumption by the increasing number of black holes (Dark matter).
Fireballs produced by Sprites or by Electro Magnetic Solar activity are good candidates for the Fireball mysteries on Earth, like the Tunguska mystery in Siberia in 1908.
So called Small Comets seem to have no relation with Fireball events.
