Recap – you already know this –
A particle is only probably somewhere, albeit tied down by it’s Planck length, it is mostly somewhere, but it is a probability wave – particle-like only insomuch as as the crest of that wave pokes up noticeably. All the other places it also is, but rather less so, well that’s the quantum foam.
So how does this speak to gravity?
A large mass is a place where there’s lots of stuff. That is to say a place where lots of stuff more probably is than is not. So, why does other stuff want to be there? – Why does gravity pull? Why is mass attractive?
Well think about it. A large mass is a place where there is a high probability of stuff being.
Now here’s another little bit of stuff.
And there’s that place where there is a high probability of stuff being (a mass).
A high probability of stuff, ANY stuff, being there. Our little other bit of stuff for instance, is more likely to be there, because there is already a likelihood of stuff (ANY stuff) being there (THAT’s what a big mass that exhibits gravitational attraction, IS).
So the the probability wave of our little attracted particle is more likely to crest closer to where all the other stuff is, so it does just that, it moves toward the mass, it hones in toward where the probability of it being is higher. With each Planck length tick of the time dimension the temporo-spatial coordinates of its probably wave crest gets closer to where the other wave crests are, and synergistically they wind-up the probability and it accelerates, jumping proportionally closer with each Plank tick.
The reason why accelleration is a squaring of velocity, is connected with the right-angle relationship between the dimensions things can move in. Dimensions like time and space are of course just potential directions that things can probabilistically pop up in. Our particle at any point on the time line (T-axis) is a set distance from the centre of mass (z-axis), and so has (conventionally) only to count the density (probability) of its fellow in its x and y axes of the “shell” around the centre of mass where it currently is. The progress as it steps along z toward the centre as t passes contracts the available surface area of the x-y shell according to the inverse square law, so acceleration toward the centre (increased probability of being at the centre) increases as a square. G is always measured in metres per second per second. Acceleration per second per second – i.e. squared – is just an artefact of the way the area of a nest of spherical shells around a point contracts, like bringing the spots on the shrinking balloon closer together, thus making the likelihood of spots being near each other, higher.
The quantum theory of gravity is just a self-fulfilling prophecy. The more stuff is likely to be somewhere (and demonstrably this probability is so if the stuff is there), the more all stuff is likely to be there, so it in that direction the crest of its probability wave moves, accelerating as it goes along.
As always, the way things are arranged is elegantly simple.
You may ask where does a guy with not a huge amount of training in physics get such ideas. Well…

19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
