A new definition of entropy is introduced using a model that simulates an expanding space-time compatible with the fundamental principle of cosmology. The entropy is obtained by mean of a state function that measures the variation of the space-time normal curvature, from a highly compressed space to a lower compressed space. The defined entropy leads to work out a new understanding of the earliest conditions that last for a period estimated to 380,000 years after the Big Bang. It leads to understand via a short period of inflation the process that generates the uniform distribution of matter and energy at the surface of the last scattering. It involves gravitational singularities in a process of gradual decompression propitious to the incubation of matter recombination, and it allows to trace back gravity origin.

使用模拟与宇宙学基本原理兼容的扩展时空的模型引入了熵的新定义。熵是通过测量时空法向曲率从高度压缩空间到较低压缩空间的变化的状态函数来获得的。定义的熵使我们对最早的条件有了新的认识，这些条件持续了估计大爆炸后 38 万年的时间。它导致我们通过短时期的膨胀来理解在最后散射表面产生物质和能量均匀分布的过程。它涉及逐渐减压过程中的引力奇点，有利于物质重组的孵化，并且它允许追溯引力起源。
