本文提出了一个关于宇宙动力学视界的协变熵猜想。在我们的猜想形成之后,我们在具有开放、平坦和封闭空间几何的绝热膨胀宇宙中测试了它的有效性,在这些宇宙中,我们的猜想在某种意义上也可以被视为广义热力学第二定律的宇宙学版本。
We here propose a covariant entropy conjecture on cosmological dynamical horizon. After the formulation of our conjecture, we test its validity in adiabatically expanding universes with open, flat and closed spatial geometry, where our conjecture can also be viewed as a cosmological version of the generalized second law of thermodynamics in some sense.
