Two micro black hole Tadpoles are attracted to each other by black hole gravity (see below) and able to merge with a second tadpole to form a Herbig Haro system to form a new star, out of the Virtual Axion Vacuum at the Penrose trapped space horizon, by a disc forming nebula and star in the middle.
Equal sized Black Holes do not merge but repel each other:see: LIGO VIRGO.
The New Physics Trapped Space Horizon around each black hole even sunspot micro black holes forming dual Herbig Haro star forming systems, as the base for the automatic multiplication by gravity of stars out of the virtual vacyym
