As predicted by Q-FFF Theory, in the middle of dual HH black holes a new black hole will be created by small (unequal sized) merger black holes which is supposed to grow at the center of the new galaxy.
In the early universe these black holes are the largest in the universe, able to eat not only smaller BHs and radiation of the vacuum but even all Fermionic matter as the start of a Quasar.
Smaller BHs are NOT supposed to consume Fermionic matter due to their strongly curved Schwarzshield horizon able to repel spinning Fermions ( string propellers with Calabi Yau disc surface) ) and channel them into two or more jets..
Quasars are supposed to be the largest BHs able to consume Fermions, ending life as a Quasar in the middle of huge dead galaxies and the start of the contracting universe into a cyclic universe.

According to Quantum Function Follows Form Theory, the Big Bang was the evaporation and splitting of a former Big Crunch black hole nucleus of compressed Axion Higgs particles into the oscillating Axion /Higgs field vacuum lattice respectively chunky nuclei of dark matter black holes.
The vacuum Lattice is supposed to represent a dynamic reference frame and the so called Dark Energy or Zero Point Energy acting as the motor for all Fermion spin and as the transfer medium for all photon information, leading to local lightspeed and local time.

The origin of Quasars? Monster Black holes central in "High- Z" Galaxy Clusters or Dead Galaxies.
According to Q-FFF Theory, normal black holes repel propeller shaped rigid fermions (with a Calabi Yau surface) by the large curvature angle of the horizon,
Then Monster black holes seem to eat fermions a go go- caused by the much smaller Schwarzschild horizon curvature- angle and as a consequence become a Quasar eating all the stuff around in contrast with ejecting all femion plasma into two jets.

Question: What is the minimum black hole horizon radius to change a black hole into a Fermion eating Quasar?
At least, less than the Abell 85 BH: 40 billion the mass of the sun, which is in line with present estimates of Quasars: Wikipedia: A Quasar is an extremely luminous active galactic nucleus (AGN), in which a supermassive black hole with mass ranging from millions to billions of times the mass of the Sun.
The smallest Quasar seems to be: PKS 0405-385. with a radiation peak variability less than an hour.
