There is much ado about emergent gravity these days. But what's the physical basis for this entropic force? In a stretching piece of rubber the molecules of rubber provide the basis, but what is the physical basis for entropic gravity?

There is an article in Scientific American this month about emergent space/time from quantum entanglement "Tangled up in Spacetime"January 2017. It looks at the hologram equivalence of 3Dimention with Time and Gravity and one of a 2Dimention on a higher plane without them. There seems to be a relationship to entanglement and spacetime. There is also work recently done that mapped energy density (basis of gravity) and entanglement from a 2D plane to a 3D plane, where gravity was not considered fundamental but emergent. It was based on there being particles of spacetime, without caring what these particles are.
