Black hole mass related merger dynamics and universal contraction.

6000 small S-Nova black holes in the Milky Way center (green spots below) is a  support for the BH family distribution according to Quantum FFF Theory. (see right below).  However Abell 520 cluster seems to centralize  massive 1e an 2e Galaxy Anchor BHs (GABHs) in a DM core after merging of three clusters.(below left).

Do we live inside a 3D simulator multiverse, with a steering wheel in our hands and a break/ veto pedal?

IMHO, we live in one part of a restricted number (8-12) of REAL not simulated, CP symmetric entangled universes, which can be compared with a raspberry shaped Multiverse with instant Pilot Wave entanglement between CP (Charge Parity) symmetric copy particles (Quanta) at long multiverse distances, to keep all universes each others exact CP symmetric copies.
As a consequence, we are individual partners of a group "copy selfs" only able to initiate and VETO an act or decision for the rest of the group. 
Benjamin Libet already suggested in1964 comparable possibilities about our free will based on his measurements of brain- muscle reaction times of about 500 msec. see: http://vixra.org/pdf/1612.0026v2.pdf

Conclusion, still we may look at one of 8 or 12 fold 3D synchonized simulator screens. with interconnected steering wheels but individual Break/Veto pedals for individual veto action, which is the only "free will" we may have.
So if we are not enough educated in social responsibility, then aggression and even war will be around the corner.

Many Worlds (8 or 12) with instant Pilot Wave entanglement between CP symmetric copy particles= Quantum FFF Theory.

Quantum FFF Theory can be compared with Many Worlds (8 or 12) with instant Pilot Wave entanglement between CP (Charge Parity) symmetric copy particles (Quanta) at long multiversal distances, to keep all universes CP symmetric copies.

Instant Broglie Bohm Pilot Waves, the Origin of All Entanglement Effects in the Lab and Wavefunction Collapses in Our Universe as Related to Our Opposing Anti-Copy Universe(s) According to Quantum FFF Theory.

Less Dark Matter Rotation Influence on Early Galaxies.

According to Quantum FFF Theory. ( Function Follows Form) Dark Matter is the same as Black Holes of variable sizes.  see: http://vixra.org/pdf/1503.0186v5.pdf  
Conclusion:
young galaxies start only with Super Nova Dark Matter Black Hole production located in the galaxy Halo bubble and line by line merging into the central giant BH. Second:  after merging with other galaxies, the dark matter content suddenly increases.

Different families of Dark Matter Black Holes.

Primary- Secondary Galaxy Anchor Black Holes (GABHs), (Globular Dwarfs) one growing Central BH and Stellar/Dwarf Anchor Black Holes, (SABHs), According to Quantum FFF Theory.

How does all these black holes keep their mutual distance? exept for the small BH near the central BH and BHs with LIGO ratios?
By hydrogen pushing tails produced by the BH itself via pair and quark production at their horizons, pushing away from the local center of gravity.

DarkMatter Black Holes are Entropy Dumpsters eating the dark energy vacuum.

Galaxy cluster based Dark Matter Black Hole vacuum eating as the origin of the Hubble Redshift and background lensing effects by Planck length variation.

A strong support for the non Accelerating but Decelerating universal expansion.
