宇宙学中的简单性：添加男性化，删除$Λ$，保留经典GR
Simplicity in cosmology: add virialisation, remove $Λ$, keep classical GR
摘要：
现今的河外星系观测大多是相当好地模拟了一个广义相对论模型，$Λ$ CDM模型。该模型似乎超越了已知物理学的极限，要求宇宙由“暗能量”主导。然而，该模型牺牲了物理上的简单性，而支持应用数学上的简单性。一个物理上更简单的，广义相对论的替代$Λ$ CDM模型在这里描述，以及初步的观测检查。因此，它将被认为是银河系外的意见，如距离-模量-红移关系的Ia型超新星是很好的模型内的经典广义相对论，没有增加“新的物理”。
英文摘要：
Present-day extragalactic observations are mostly rather well-modelled by a general-relativistic model, the $Λ$ CDM model. The model appears to surpass the limits of known physics by requiring that the Universe be dominated by "dark energy". However, the model sacrifices physical simplicity in favour of applied mathematical simplicity. A physically simpler, general-relativistic alternative to the $Λ$ CDM model is described here, along with preliminary observational checks. Thus, it will be argued that extragalactic observations such as the distance-modulus--redshift relation of type Ia supernovae are well-modelled within classical general relativity, without the addition of "new physics".
