The dual Black Hole Herbig Haro system is still NOT UNDERSTOOD by physics community !! see below:
The great Mystery discovered by Q-FFF Model:
15% equal black holes do not merge but repel each other to form Herbig Haro star/galaxy forming systems:
Also; the creation of open starclusters. ("closed" star clusters are only possible around dual stabilized huge Galaxy clusters ( former merge Herbig Haro Galaxy black holes at the outside of a galaxy.
The origin of dual and triple stars, by the growing stars above its maximum mass, more than the dual SABHs ( Stellar Anchor Black Holes) can controle by its vacuum polarisation of space.
Splitting Tadpole travelling black Holes creating smaller Herbig Haro dual black hole systems in the wake of the splitting tadpole black hole.
