In Q-FFF Theory however it is assumed that NO Fermion can pass this Penrose horizon, but is acting as a Fermion repeller and creator by a new Axion vacuum collider effect, with local pair production outside the Penrose Horizon.
By the incoming vacuum gravity pressure, the electrons will stay at the outside (-charge) of the plasma ball around a black hole and the heavier positron based positive quarks will be pushed stay more at the inside.
It is also postulated that the vacuum is compared with a 3D lattice of fluxtubes with the Planck length,
as the home for oscillating Axion vacuum particles originating the Casimir effect and so called dark energy.
The Axion vacuum is supposed to be eaten by black holes resulting into fluxtube elongating and additional redshift of all photons passing by, but also a Casimir quantum gravity pressure effect.
The result of Axion flux elongation is supposed to be an important origin of the Hubble redshift and
Universe expansion.
Even the complex structure of Planetary Nebula can be explained, if we assume that all expelled star spots of a supernova explosion are represented as Penrose black holes, producing and repelling plasma clouds by transformation of Axion vacuum particles.
Such expelled star spot black holes will show clear plasma tails at the back of each star spot black hole also observed as Proplyds.
The different sizes of the former star spot black holes are supposed to be the origin of the complex plasma trails observed in many Nebula.
Larger star spot Proplyds, will produce bigger plasma trails and has a larger electric charge.
Secondly, each Proplyd its pushing plasma tail is guided by stellar winds of exploding stars ( Helix Nebula) and other surrounding black holes and pointing opposite to the acceleration direction of the Proplyd. which explains the complex structures of Nebula.
The ultimate goal of the self propelled Proplyds seems to bet the formation of a dual Herbig Haro system to form new stars or Dead ( Dark) Stars or find a 15% larger black hole to merge into one bigger BH.
