The Herbig Haro Big Bang building equal sized Black Hole systems forming stars out of the string vacuum.

 

Classical Disc Galaxy Bulges are thought to be the result of merging with smaller Structures ( 2, 3,,e GABHs)

 Dual X-ray and Gamma Ray Bubbles at both sides of the  Milky Way, complexed by secondary merger GABHs and older star systems of smaller Herbig Haro Galaxy Mergers.

Below: Two different disc galaxies, with or without a central Bulge with old stars.

Sunspots, Comets and Ball Lightnings are interference micro black holes.

In String Theory called Q-FFF ( Quantum Function Follows Form) Theory all black holes are based on a compact string nucleus, with different numbers of strings. So: it is not a singularity.
There are micro black holes called comets and ball lightnings even Sprites and Elves.
Conclusion: there are different sorts of black holes (BHs);
A: Stellar Implosion BHs (Super Novas) with a nucleus of compacted strings.
B: Interference String Knot BHs also with a nucleus of compacted strings and made by Magnetic colliding photon knots, compressed by the local oscillating vacuum strings called Axions.
C: The Big Crunch/ Bang Black Hole, in balance with the decreasing pressure of the oscillating Axion vacuum impacts consumed by the latest BHs.

A Physics and Energy revolution by an OLD forgotten DM- BH- BIG Hawking-Penrose idea?

See: the New Black Hole Physics with Penrose-Vuyk fermion repelling horizon.
An old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter.
It fell out of favor for decades. NOW the Penrose trapped vacuum HORIZON in combination with Fermion repelling of Q-FFF THEORY , IT SEEMS THE RIGHT SOLUTION.

Galaxy-Size Double Bubbles Discovered Towering Over the Milky Way

Galaxy-Size Double Bubbles Discovered Towering Over the Milky Way, larger than the Fermi bubbles.!! a new support for Q-FFF Model
