The universe is dominated by a non-zero energy of the vacuum (ρΛ) that is making the expansion of the universe accelerate. This acceleration produces a cosmic event horizon with associated entropy SCEH ~ ρΛ-1. When this entropy is included in the entropy budget of the universe, it dominates the entropy of the next largest reservoir, supermassive black holes, by 19 orders of magnitude: 10122 k >> 10103 k. Here we address the issue of how one might apply the maximum entropy production principle (MEPP) to the processes responsible for the production of the cosmic event horizon entropy.
