Show affiliationsIf the present acceleration of the universe is due to a cosmological constant, λ, then the entropy of the microwave background is bounded. It cannot exceed λ−3/4 ~ 1091, which is much less than the entropy of empty de Sitter space λ−1 ~ 10122. This is due to the limited efficiency of storing entropy by local field theoretical degrees of freedom. The observed entropy of the microwave background is of O(1085).
