If 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).
