Quantum gravity and space's informational entropy

[nsane.forums]

In my last report from Physics@FOM, I will talk about something I am truly not competent to discuss: "Holography, ADS/CFT and the emergence of gravity." I realize that I am not always the sharpest knife in the drawer, but I have never found myself so lost so quickly in a presentation. I think this comes from the difficulties in conveying some very new concepts by Erik Verlinde, who is still in the process of grappling with them himself. Nevertheless, let me try.

Holography, and anti de Sitter space/conformal field theory are two ways of describing the bending of space and the entropy associated with it. The two models are very closely related to each other. So close that, according to Wikipedia—the fount of all reliable knowledge—theorists can't agree if they are the same or not. But the point about both is that they resolve the problem of unifying gravity with quantum mechanics by getting rid of gravity.
