Space curvature or quantum density
Einstein established that curvature of space creates gravity. Also energy curves space.
Now. Let's "imagine" (becouse I more than imagine it, let's say it makes more sense to me).
There is no curvature of space. But what if some quantum background (maybe dark energy, maybe other thing) has different densities through the universe, exactly in the same proportion of curvature of space.
That is, space does not curve, but this quantum background behaves exactly as if space were curved.
Example, when there is energy, this quantum field depletes in the proportions space would curve.
Different values of this quantum field would then create a gravity force between them.
Time passes at different peace in one quantum field with certain density than another, like space curvature.
Now, what if one galaxy on its formation aquired much more of this quantum field than another?
It would be as if the laws of nature were the same than our galaxy, but with a different gravity constant. Galaxies would spin faster with the same mass. (Note, this indeed is what happens in some galaxies, though the explanation is that a dark matter substance is more abundant there). Dark matter then I put it as background field.
That has big implications. If space does not curve and we have a background density, what happens in a blackhole? Does it have infinite curvature? Or does better have no backround density?
If gravity goes from high density to small densities, makes sense in the blackhole densities are 0.
The blackhole is not empty, it is full of matter, compacted at the maximum level, but at the same time when there are high energies, this background quantum field depletes, completely in this extreme case.
Space is limited, so if more matter wants to come in, one thing will happen, the area of the blackhole with 0 density will increase. (and currently increases, blackhole grows). There is a sharp change of quantum density from 0 to normal universe densities, that is why maybe blackholes have that much gravity pull.

Finally, what if that background quantum field is simply Higgs field. Yes, Higgs density may not be necessarly uniform in strength everywhere. Indeed may be very well the fabric behind general relativity (gravity), dark matter (different Higgs in certain galaxies, dark energy (Higgs is expanding) or even the famous quantum foam when it decomposes constanly on other particles, and form Higgs back again.
