By replacing the fifth postulate in the preceding paper with the condition of spherical symmetry of space we again obtain the Friedmann universe in relativistic cosmology.
将前文中第五个假定改为“空间具球面的对称性”后我们仍遵出费烈特猛宇宙。
Derived from Einstein's theory of General Relativity, the two Friedmann equations describe the life of the entire universe, from fiery Big Bang birth to chilly accelerated expansion death.
弗里德曼方程派生自爱因斯坦的广义相对论。这两个方程式描述了整个宇宙的生命历程——由宇宙大爆炸时的暴烈到不断加速膨胀后的死寂。
