人们可以把宇宙常数Λ看作广义相对论中的一个动力学变量。要做到这一点，最简单的方法是将引力场与一个三指数张量相耦合。在黑洞溶液中，Λ以积分常数(“头发”)的形式出现，与黑洞的总质量和电荷具有相似的基础。气泡的辐射有一个量子过程，类似于粒子发射，它会自发地降低Λ。黑洞热力学的一般定律似乎仍然成立。
One may consider the cosmological constant Λ as a dynamical variable in general relativity. The simplest way of doing this is to couple the gravitational field to a three-index tensor. In a black hole solution Λ appears then as an integration constant (“hair”) in a similar footing with the total mass and charges of the hole. There is a quantum process of radiation of bubbles, analogous to particle emission, which spontaneously reduces Λ. The general laws of black hole thermodynamics still appear to hold.
