论文摘要
标准模型宇宙学中的大爆炸奇点表明，“早期宇宙”量子重力现象学中的研究计划。人们通常认为通货膨胀通过动态稀释的论点来破坏该计划的前景，但是最近在通货膨胀宇宙学中，这种观点以“跨普兰克审查”的猜想形式引起了争议。同时，在通货膨胀宇宙学之外使用了跨普兰克审查制度，以激发替代性的早期宇宙场景，这些场景与量子重力的持续理论紧密相关。在产生的趋势趋向于早期宇宙量子重力现象学内部和不通货膨胀的趋势时，Ijjas和Steindhardt提出了进一步的选择：“广义宇宙审查制度”原理。我将广义的宇宙审查原则与其同名宇宙审查制度的逻辑进行了对比。我还评论了有效的现场理论方法中的基本问题，超出了标准模型，这将基于该原则。
The Big Bang singularity in standard model cosmology suggests a program of study in 'early universe' quantum gravity phenomenology. Inflation is usually thought to undermine this program's prospects by means of a dynamical diluting argument, but such a view has recently been disputed within inflationary cosmology, in the form of a 'trans-Planckian censorship' conjecture. Meanwhile, trans-Planckian censorship has been used outside of inflationary cosmology to motivate alternative early universe scenarios that are tightly linked to ongoing theorizing in quantum gravity. Against the resulting trend toward early universe quantum gravity phenomenology within and without inflation, Ijjas and Steindhardt suggest a further alternative: a 'generalized cosmic censorship' principle. I contrast the generalized cosmic censorship principle with the logic of its namesake, the cosmic censorship conjectures. I also remark on foundational concerns in the effective field theory approach to cosmology beyond the standard model, which would be based on that principle.
