Abstract
The generalized second law of gravitational thermodynamics is applied to the present era of accelerated expansion of the Universe. In spite of the fact that the entropy of matter and relic gravitational waves inside the event horizon diminish, the mentioned law is fulfilled provided that the expression for the entropy density of the gravitational waves satisfies a certain condition.Comment: 10 pages, 1 postscript figure, uses revtex4, PACS numbers: 04.30.-w, 98.80.-k published in the Physical ReviewKeywords
