This is the way Reality works.

You may remember when I postulated that black holes are at the centre of all systems. The following research may back up this proposition https://www.slashgear.com/researchers-believe-dark-matter-could-be-composed-of-primordial-black-holes-30652903/.

In 3dAbstractions, black holes correspond to 3dStar objects. A 3dStar is a central 3dSystem. It is timeless and contains the state of the system the 3dStar is central to. It can also be a Hierarchical Finite State Machine that changes when an event is received from the outer system. A black hole is likely to behave similarly. An event for a black hole would likely be a system falling into it.

I think I also postulated that the total mass of a 3dSystem is the sum of the masses of itself (the 3dStar) plus the masses of its 3dSubsystems. Given that a 3dSystem describes any system in the the universe, then it follows that 3dStars and therefore black holes are included in the mass of the universe.

Yes.
You offered no evidence, so we laughed at you.

The following research may back up this proposition

Or not...
" Nevertheless, tight limits on their abundance have been set up from various astrophysical and cosmological observations, so that it is now excluded that they contribute significantly to dark matter over most of the plausible mass range."
