How equally sized Black holes can come across shortly and split into
Herbig Haro dumbbells with star forming in between.
How different sized black holes are able to downscale each other.
The smaller black hole will always split the larger one.
The Eagle example of splitting and pairing black holes to become starforming Herbig Haro dumbbell systems.
