Dark energy: Mystery of the Millenium
T. Padmanabhan http://arxiv.org/abs/astroph/0603114 This is an impressive paper, based on a talk and quite readable.

Indeed, Kea. I read that one yesterday. Padmanabhan has a way with words.

I just finished reading it. What a lot of good solid MEAT in that paper. Obviously based on decades of deep thought by himself and semingly everybody else, it really does give us a general NECESSARY framework for evaluating quantum gravity programs.

He's got his references nicely organized by topic, I noticed. I liked the way he synthesized holography, thermodynamics, and special viewpoints to get his "model that works". Very convincing. I was especially diverted by his choice of variables for the action: the metric, the Christoffel symbols, and the curvature tensor. Noting also that the curvature tensor, in this representstion, depends on the Christoffel symbols but not the metric. I wonder how many decades of pondering the common wisdom of GR it took to come up with that!
