宇宙的熵

Entropy of the Universe

Marcelo Samuel Berman

摘要:

在讨论了广义相对论转变为不太复杂的理论的几种极限情况之后,我们发现,在爱因斯坦场方程的正确的物理学和宇宙学弱场极限下,宇宙的熵是R^(3/2)相关的,其中R代表因果相关宇宙的半径。因此,熵在宇宙中增长,与标准宇宙学的预测相反。

英文摘要:

After a discussion on several limiting cases where General Relativity turns into less sophisticated theories, we find that in the correct thermodynamical and cosmological weak field limit of Einstein's field equations the entropy of the Universe is R^(3/2) -- dependent, where R stands for the radius of the causally related Universe. Thus, entropy grows in the Universe, contrary to Standard Cosmology prediction.
