The 1 Parsec problem of SMBHs, (Not Merging) seems the same as the Creation of dual Herbig Haro Travelling Bowshock black holes.(not merging) Gravitational waves from a supermassive black hole merger haven’t been heard yet !!! This is connected to the 1 Parsec problem, which can be solved in Q-FFF Theory by the violation of the second law of thermodynamics around each black hole.

 Below: Equal sized Black Holes (<15% Ratio) DO NOT MERGE ! (LIGO ) even SMBHs.

Below: according to Q-FFF Theory:

All Black Holes attract distant matter, into a plasma disc, or Plasma Tail ( see travelling Tadpole BHs) but do not consume but even REPEL close by matter. 

New plasma is even created at the Penrose-Q-FFF "Trapped space Horizon" or light horizon and transferred to two perpendicular jets, or one plasma tail. 

Plasma is created out of the virtual compressed vacuum particles in action as an opposite virtual vacuum (AXION transforming) particle collider.   

Below: a Micro Black hole ball lightning with a self produced plasma tail.

Below: The Plasma Bar pushes both black holes away.

Below: The Triple Black Hole situation leaving an Ultra Diffuse Galaxy behind. (EDG) as the base for merging of three BHs into TWO,
