I am imagining gravity as the Special Theory of Brownian Motion, just like there is a Special Theory of Relativity...

"Brownian motion, or pedesis (from Ancient Greek word for "leaping"), is the random motion of particles suspended in a medium"

https://en.wikipedia.org/wiki/Brownian_motion

Sometimes, events that are expected to occur at random, occur an inordinate number of times, like rolling sixes a dozen times in a row. The universe is so old that even 14 billion years is less than the blink of an eye in comparison. For this relatively short time (albeit an eternity for humans), all the particles in the universe have, improbably, been moving in synchrony, as if there were some sort of inverse square law of gravity. But there is no such thing as "gravity". The universe has been rolling sixes for 14 billion years!

And now we have a Special Theory of Brownian Motion, which is a probabilistic theory of gravity, and which therefore might be unified with Quantum Mechanics.
