DGP Gravity

(DGP Model)
(alternative theory of gravity addressing "dark energy")

DGP Gravity (or DGP Model) is a recent theory of Gravity explaining the same dynamics that Dark Energy explains. It incorporates an additional space dimension. It is not widely accepted in astrophysics, has not been successfully embedded in String Theory, and the claim has been made that Cosmic Microwave Background (CMB) and Baryon Acoustic Oscillations (BAO) observations conflict with it.

It was developed in 2000 by Gia Dvali, Gregory Gabadadze, and Massimo Porrati (for DGP).
