摘要
标准模型宇宙学中的大爆炸奇点提示了一个“早期宇宙”量子引力现象学的研究纲领。暴胀通常被认为通过一种动力学稀释论证削弱了该程序的前景，但近来在暴胀宇宙学内部，这一观点以“跨普朗克审查”猜想的形式受到质疑。同时，跨普朗克审查在暴胀宇宙学之外被用来推动与量子引力中正在进行理论化紧密相关的另类早期宇宙情景。针对由此产生的在暴胀内外走向早期宇宙量子引力现象学的趋势，Ijjas和Steindhardt提出了进一步的替代方案：一种“广义宇宙审查”原理。我将广义宇宙审查原理与其同名者即宇宙审查猜想的逻辑进行对比。我还评述了超越标准模型的宇宙学有效场论方法中基于该原理的基础性关切。

备注
Final preprint version, accepted at Foundations of Physics. An early version of this paper misstated the scope of the intended argument, and was subsequently withdrawn out of respect for those invested in related areas of research. Versions thereafter resolved that issue, among other revisions. Notably, in the present version, technical details of the toy model at the end have been clarified
