Geometry of the Universe and Its Relation to Entropy and Information

Abstract

In an effort to investigate a possible relation between geometry and information, we establish a relation of the Ricci scalar in the Robertson-Walker metric of the cosmological Friedmann model to the number of informationNand entropyS. This is with the help of a previously derived result that relates the Hubble parameter to the number of informationN. We find that the Ricci scalar has a dependence which is inversely proportional to the number of informationNand entropyS. Similarly, a nonzero number of information would imply a finite Ricci scalar, and therefore space time will unfold. Finally, using the maximum number of information existing in the universe, we obtain a numerical value for the Ricci scalar to beO(10-52) m-2.
