At the edge of the universe we observe the birth of the Inflationary universe by the splitting Singuarity black hole being the MEGA Dark Matter Nucleus Black hole remnant of a former universe.
Some equal sized splitted black holes seem to be able to form a Herbig Haro system to form stars and galaxies in the middle between the two BHs located at the end of the dual Herbig Haro Jets.
Single black holes seem to be able to become a travelling "TADPOLE black hole" accelerated and guided by its self produced plasma tail.
The self produced tail Is assumed to be created at the so called "Trapped Space horizon" of each black holes. prdicted by Roger Penrose.
