Aristotel believed a things natural state was to be still. Things naturally come to a stop unless there is some force acting on them. Things fall because they want to be still. To be still they need to be touching the ground. Then Tycho Brahe and Kepler worked out how the planets moved but were mystified as to why. Then one day when sitting under a tree full of ripe apples it occurred to Newton that it might be gravity that makes the planets behave like that and his theory of gravity has stood until recent times. Mercury wasn’t orbiting quite the way Newtons laws of motion predicted. Then Einstein came up with a revolutionary and much more complex view of gravity. And it fit the observations made of Mercury nicely. We still use Newtons laws of gravity a lot. It’s fairly simple and is useful for everything from bridges to airplanes. But when we start putting things in space we need Einstein’s more complex explanation of gravity.
But when we look deep into space things aren’t right. The universe is expanding too fast and the galaxies are spinning too fast. There is a lot of unaccounted for mass. It could be the observations are wrong; the observations are based on the behaviour of pulsars. So there is some room for something to have gone wrong with the maths. It could be we need a different theory of gravity when we get to the cosmological scale. Or it could be quantum black holes.
With the intense pressure at the Big Bang tiny parcels of matter were compressed to blackholes the size quantum particles. The rapid expansion didn’t erase all the abnormalities. These things pass straight through objects like the earth. Maybe eating a quark and sending a subatomic particle into decay. These clouds of black holes on the edge of existence would have no effect on the universe except to dramatically increase its mass.
There are larger ones too; observations suggest there is an object the mass of Neptune out beyond the orbit of Pluto. Things aren’t moving around The Ort Cloud like they should, a mass the size of Neptune is missing. It hasn’t been seen when much smaller objects have been seen. Because it’s a black hole the size of a basket ball; there is no way we could see the lens effect of a black hole that size. This would explain dark matter and dark energy because the blackhole would steeply bend space time around its orbit, slowing time in the Solar System and making the universe seem to go faster than it should.
It has been pointed out to me a blackhole this size wouldn’t have a sufficient lenz effect to get the results we are getting. So that would suggest there are two blackholes the Earth is involved with. It would seem the Earth is orbiting a much larger blackhole but non the lees modest at say 100 solar masses. There’s blackholes everywhere it’s just we can’t see them.

The science of this

OK; it’s been fun playing with this idea; but the science isn’t looking good. Blackholes are subject to decay, gravity stops being an issue at the event horizon and something different and very slow is happening with time inside the hole. Small blackholes decay faster than big ones; so my quantum blackholes would rapidly decay. But depending on the mass of the hole, given how slow things happen inside the hole, and the fact they are going to eat some matter, there could be clouds of blackholes getting around.
But they would have things orbiting them. They would be like atoms but with a much different structure. At this point they become a small part of a much larger unit. This strange atom like object would have shown up in our sensors. The bigger blackholes would have stuff orbiting them too. Nothing or close to nothing happens in a blackhole. But all sorts of shit goes down near a blackhole. The event horizon will be at the Planck Temperature it will slowly cool down to the temperature of our Sun and gradually cool from there. There would be powerful beams of energy created by the magnetic field shooting out into space from its poles. The magnetic field would be huge; we would see objects like that easily.
