The Innermost Stable Circular Orbit (ISCO) of each black hole.= Penrose Trapped Space Horizon ( acting as an Axion particle collider, creating nagative charged plasma) will Change the World of Science. Negative plasma remains by the decay of neutrons (ddu) into Mesons (du) and leaving (d) abundant negative electrons behind.
The Retrogade maximal spinning Black Holes seem to be the most productive Fermion plasma producers sending the Fermions into both jets and discs ( by equal electrical charged (-) areas..
Conclusion of Q-FFF model: NOTHING FERMIONIC PLASMA FALLS INTO THE BLACK HOLE. DUE TO THE FERMIONIC PROPELLER SHAPE. PUSHED AWAY FROM THE HORIZON.
