通过使用数值广义相对论的工具进行完全非微扰分析，我们证明了缓慢收缩的周期是一个“超平滑”的宇宙阶段，它以经典和量子力学的方式使宇宙均匀、各向同性和扁平，而且到目前为止可以比以前的研究实现得更强劲和更快。(C)2020年提交人(S)。爱思唯尔出版公司(Elsevier B.V.)
Performing a fully non-perturbative analysis using the tools of numerical general relativity, we demonstrate that a period of slow contraction is a "supersmoothing" cosmological phase that homogenizes, isotropizes and flattens the universe both classically and quantum mechanically and can do so far more robustly and rapidly than had been realized in earlier studies.
