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.

We all know that life on Earth gets it's energy from the Sun.

But we also know that's an approximation we tell kids, really life gets low entropy photons from the Sun, does it's thing, and then emits high entropy infrared waste heat. Energy is conserved, while entropy increases.

But where did the Sun got it's low entropy photons to start with? From gravity, empty uniform space has low entropy, which got "scooped up" as the Sun formed.

EDIT: not sure why this is downvoted, is the explanation Nobel Physics laureate Roger Penrose gives: https://g.co/gemini/share/bd9a55da02b6

Entropic gravity is a compelling framework. I think that most Physicists admit that it would be nice to believe that the yet unknown theory of everything is microscopic and quantum mechanical, and that the global and exquisitly weak force of gravity emerges from that theory as a sort of accounting error.

But there are so many potential assumptions baked into these theories that it's hard to believe when they claim, "look, Einstein's field equations."

Like some sort of buoyancy?

I don't get it.

To me, entropy is not a physical thing, but a measure of our imperfect knowledge about a system. We can only measure the bulk properties of matter, so we've made up a number to quantify how imperfect the bulk properties describe the true microscopic state of the system. But if we had the ability to zoom into the microscopic level, entropy would make no sense.

So I don't see how gravity or any other fundamental physical interaction could follow from entropy. It's a made-up thing by humans.
