My guess would be the answer is right in the part before you quote? If theres more "space" (imagining more space coordinates possible) for me on the left than on the right, me jumping to a random location would statistically move me left.
Repeating results in movement, getting closer to the object intensifies this effect, results in acceleration.
Solid objects are products of electric charge preventing atoms/particles from hitting each other, I dont think that has to have to do anything with gravity in this example?
I don't understand the more space thing then. Is this more space due to spacetime curvature or something else.
E.g. if we have earth and moon:
Why is there more space from the moon towards earth than away?
