摘要

在这篇综述文章中，我们首先讨论了标准弗里德曼宇宙学中大爆炸曲率奇异性的一个可能的正则化，其中曲率奇异性被时空缺陷取代。然后，我们考虑一个新的物理阶段导致了这种特殊的时空缺陷的假设。具体来说，我们开始使用IIB矩阵模型进行探索性计算，该模型已被提出为非扰动超弦理论（M-理论）的一个特定公式。

M-theory and the Birth of the Universe

In this review article, we first discuss a possible regularization of the big bang curvature singularity of the standard Friedmann cosmology, where the curvature singularity is replaced by a spacetime defect. We then consider the hypothesis that a new physics phase gave rise to this particular spacetime defect. Specifically, we set out on an explorative calculation using the IIB matrix model, which has been proposed as a particular formulation of nonperturbative superstring theory (M-theory).
