大爆炸核合成对压力自引力的限制

Big Bang Nucleosynthesis Constraints on the Self-Gravity of Pressure

Saul Rappaport, Josiah Schwab, Scott Burles, Gary Steigman

摘要:

利用大爆炸核合成和目前对轻元素丰度的高精度测量,我们限制了早期宇宙中辐射压力的自引力。压力的自引力是严格非牛顿的,因此我们设定的约束条件为广义相对论和标准的罗伯逊-沃克-弗里德曼宇宙学的预言提供了直接的检验。

英文摘要:

Using big bang nucleosynthesis and present, high-precision measurements of light element abundances, we constrain the self-gravity of radiation pressure in the early universe. The self-gravity of pressure is strictly non-Newtonian, and thus the constraints we set provide a direct test of this prediction of general relativity and of the standard, Robertson-Walker-Friedmann cosmology.
