Below: ODD structures before the CDM era.
According to Q-FFF Theory. 2 types. single- and dual types.
The baryonic/ fermionic plasma tail can not enter the black hole through the horizon and will act as a pushing motor.
Why? because the concentrated Axion vacuum pressure horizon of the black hole (see Penrose) will push all fermions which are propeller shaped away from the horizon into a disc and later into the direction of both North- and South BH Jets (see image below)
This tail wil point into the direction of the largest gravity cusp in the neighbourhood. , steering each Black Hole away from the local gravity centres. forming the tubelike dark matter filaments crossing through the universe as the layman Alpha structure.
See Below: the plasma Flows created at the Penrose Trapped Space Horizon, acting as a particle collider creating pairs of symmetric Fermions later forming stable fermions and Baryons in the plasma disc and jets.
