论文摘要
我们认为大爆炸可以理解为一种镜子。我们展示了如何通过局部Lorentz和量规对称性来反映旋转器和较高旋转场的边界条件，以及时间镜（如爆炸）与空间镜（如广告边界）的不同，为观察到的左手和右手fermions的模式提供了可能的解释。通过将标准模型作为最小左右对称理论的极限，我们获得了强大的$ CP $问题的新的宇宙学解决方案，而没有斧头。
We argue that the Big Bang can be understood as a type of mirror. We show how reflecting boundary conditions for spinors and higher spin fields are fixed by local Lorentz and gauge symmetry, and how a temporal mirror (like the Bang) differs from a spatial mirror (like the AdS boundary), providing a possible explanation for the observed pattern of left- and right-handed fermions. By regarding the Standard Model as the limit of a minimal left-right symmetric theory, we obtain a new, cosmological solution of the strong $CP$ problem, without an axion.
