...an argument I've been honing over time... I'll post an explanation as a new post in this thread as soon as it is written.

Merger of black holes (or merger of two neutron stars to form a black hole) is mainstream science, based on scientific observation of the real world.
See: https://en.wikipedia.org/wiki/List_of_gravitational_wave_observations

Questions about black holes belong in the "Physics, Astronomy & Cosmology" section of the forum.
However, a proposed explanation of the structure of the cosmos based on black holes belongs in the "New Theories" section of the forum.
@scherado, I recommend that you post your explanation there instead.

I did read about the event you referenced and thank you for using the word "merger." It is precisely what I needed to advance an argument I've been honing over time.

Merge seems appropriate for two things of similar order of magnitude of mass.  But if one is tiny and the other huge, it seems more like the little one falling into and adding to the bigger one, but the process is really the same.

Does a meteor fall to Earth or do the two just merge?  Or maybe the Earth falls down onto the rock and becomes this huge meteorite on it.

It is thought that there is a supermassive black hole in the center of (nearly) every galaxy.
See https://en.wikipedia.org/wiki/Supermassive_black_hole

Supernova of a large star is very likely to produce a black hole. It is thought that there are about 30 supernovas per 1000 years in our galaxy, but ancient astronomers have only reported about 3 every 1000 years.
- One possible reason for the discrepancy is that the black hole swallows the star before it can emit the massive burst of superheated gas that glows for months.
- A more boring reason may be that the ancient Greek philosophy that "the stars are unchanging" may have inhibited Europeans from reporting such events for many centuries. But Chinese astronomers were not under this illusion.

There seems to be no controversy (in Science) with respect to the existence of the Black Hole. My question:

Is there more than one Black Hole in the Universe?

Sure. In fact in this galaxy alone there could be a million of them.
