论文摘要
我们开发并应用了解释性深度的多维描述，以对原始宇宙学中通货膨胀和弹跳范式进行比较分析。我们的分析是基于Azhar和Loeb（2021）引起的早期工作，该工作将初始条件确定为与当代宇宙学中的辩论相关的解释深度的维度。我们提出动态的微调和自主权，作为在不稳定性和跨普兰克模式的问题的背景下，分别折磨和通货膨胀方法的问题。在后一个问题的背景下，我们认为最近制定的Trans-Planckian审查制度猜想导致了动态微调和自治之间通货膨胀模型的权衡。我们最终的建议是，关于深度不同维度的解释性偏好是从对未来模型建设的启发式态度的不同态度方面最好理解的。
We develop and apply a multi-dimensional account of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial conditions fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary approaches respectively. In the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.
