论文摘要
主要使用MinisuperSpace构造和扰动，已经在循环量子宇宙学中分析了大量模型。同时，经常忽略了有效现场理论和协方差的一般物理原理。对这些成分的一致引入需要对现有情况进行重大修改。结果，没有一个更广泛的主张主要由Ashtekar学校提出 - 例如以惊人的半经典动态反弹的一般性，关于量化歧义的稳健性，协方差的实现以及对潜在观察的某些技术结果的相关性 - - - 持续审查。可以从这个结果中汲取几种可持续版本的量子宇宙学的有用课程。
A large number of models have been analyzed in loop quantum cosmology, using mainly minisuperspace constructions and perturbations. At the same time, general physics principles from effective field theory and covariance have often been ignored. A consistent introduction of these ingredients requires substantial modifications of existing scenarios. As a consequence, none of the broader claims made mainly by the Ashtekar school --- such as the genericness of bounces with astonishingly semiclassical dynamics, robustness with respect to quantization ambiguities, the realization of covariance, and the relevance of certain technical results for potential observations --- hold up to scrutiny. Several useful lessons for a sustainable version of quantum cosmology can be drawn from this outcome.
