Gravity, a fundamental force?

SOL

I was shown this earlier today and it seems absoloutely fascinating, and was wondering what some of the more physics minded people thought?

"Starting from first principles and general assumptions Newton's law of gravitation is shown to arise naturally and unavoidably in a theory in which space is emergent through a holographic scenario. Gravity is explained as an entropic force caused by changes in the information associated with the positions of material bodies. A relativistic generalization of the presented arguments directly leads to the Einstein equations. When space is emergent even Newton's law of inertia needs to be explained. The equivalence principle leads us to conclude that it is actually this law of inertia whose origin is entropic."

I don't have time to look at this at the moment, but I hope to look over it over the next few days and then comment. I'm not sure I'll understand it, but it will take me a few days to digest either way!
