Space exists around things with mass. Also, above-absolute-zero temperatures cause particles to jump around randomly.

Now if there is "more space" around particle A, particle B will have a slightly higher statistical chance of randomly jumping closer to it, than farther.

Rinse-repeat. Gravity as we know it.

Does it? A single free particle won't "jump around randomly". Thermal motion is plain Newtonian motion with an extremely high rate of collisions. There's nothing random about it (let's put quantum things aside for now).

It sounds a bit like Le Sage's theory of gravity:

Why?

Also how do you explain acceleration due to gravity with that model. How do you explain solid objects?

If space existed around things with mass, then what would you call the emptiness that replaces space the further you go away from things with mass?

Sounds fun!

Would this imply that cold objects have weaker gravity?

sounds more like the reverse to me, movement away from denser areas (less space), so like water leaking out of a container.
