Tadpoles can merge with larger tadpoles to form a larger tadpole.
Two equal sized Tadpoles can form a Herbig Haro system forming two jets by its "bowshocks" dual tadpole DM black holes and a white hole in between.
The White hole seems to polarize the vacuum into a vacuum "trapped space" or "White hole" forming Dust balls and later young stars, if the Herbig Haro black holes can create enough negative charged plasma or dust to form a strong Birkeland charge carrousel system.
