Complex galaxy / star evolution seems
to be not only created by galaxy or star merging, but even by central galaxy- and
stellar mass black hole chopping into two equal parts to form black hole based Hotspots
called Herbig Haro systems or Double Radio Galaxies.
This process is supposed to be the consequence
of the new physics Electric Dark Matter Black Hole (EDM-BH) principle of Quantum FFF Theory ( Function
Follows Forms) and supported by
observation of Triple Double Radio Galaxies and even by BH splitting in the Spire Eagle nebula..
