Has anyone got a reference to the entropy of the cosmological event horizon? Is this entropy an upper limit of the entropy inside (like a black hole) or a lower limit? I'm entertaining the idea that a shrinking cosmological event horizon puts a shrinking upper bound on the entropy inside it. And this shrinking entropy my be causing complex structures to appear such as life. It seems curious that life appeared on earth about 4 billion years ago which is about the same time that the cosmological event horizon began to shink with an acceleration in the expansion rate of the universe. Any help is appreciated. Thanks.
