I just posted this on the bibliography links thread. Thought it would be good to post for discussion as well. http://arxiv.org/abs/1002.4278 Entropic Accelerating Universe Damien A. Easson, Paul H. Frampton, George F. Smoot 10 pages, 1 figure (Submitted on 23 Feb 2010) "To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lemaître equation of dark energy which must then comprise 70% of the present cosmological energy density. We propose an alternative interpretation which takes into account the temperature intrinsic to the information holographically stored on the screen which is the surface of the universe. Dark energy is thereby obviated and the acceleration is due to an entropic force naturally arising from the information storage on a surface screen. We consider an additional quantitative approach based upon the entropy and surface terms usually neglected in General Relativity and show that this leads to the entropic accelerating universe." Like it or not, Nobel laureate George Smoot (LBL Berkeley) has jumped in bed with Erik Verlinde and is describing an "entropic force" responsible for accelerating expansion. The Smoot et al reference #6 is to Verlinde's recent paper.  E. Verlinde, arXiv:1001.0785[hep-th]. Personally I like this a lot. I also have a lot of respect for Smoot. In my view, he is the number one Observational Cosmology Nobelist at work today and really prominent and really influential. Plus this is a well-written paper. The quality is convincingly high. The kind of thing that helps allay nervous reluctance and kneejerk objections. So it changes the "entropic force" game slightly.
