Binary black holes of equal size, are assumed to form always Herbig Haro systems.

Binary black holes of equal size, are assumed to form always Herbig Haro hotspots, even in the early universe, where they created massive stars in between as the progenitors of massive Galaxies and clusters (according to Quantum FFF theory).
In near space however we find only stellar mass black hole based Herbig Haro hotspots ore even smaller dual sunspot black holes as observed in the Eagle nebula..
Left the Eagle nebula, with early galaxy formation. Right, the recently observed binary black holes in deep space.

Quantum FFF theory however, tell us that only different sizes BHs can collide with the splitting of the largest BH in two equal parts, wich are able to form hotspots of a Herbig Haro system as the base for star and galaxy formation.

Consequently, what we see here is such a HH system with TWO equal sized hotspots Black Holes!! 

Even the smallest interference black holes like sunspots and Cometary nuclei are supposed to form sets of twns with h2 O creation in between out of the vacuum itself by pair e-and e+ forming..
