论文摘要
宇宙常数$λ_{\ rm obs} $的特殊观察到的值的人类解释认为，这种值促进了恒星，行星以及最终的观察者的形成。我表明，宇宙星形成的最新分析模型预测，尽管$λ_{\ rm obs} $最大化了宇宙中恒星形成的整体效率，但生成观察者在$ \ sim400-500 \，λ_，λ_，λ_{\ rm obs} $的可能性。这些初步结果表明，恒星形成效率与观察者的产生之间的直接联系并不简单，并突出了应用人类推理所涉及的微妙之处。
The anthropic explanation for the peculiarly small observed value of the cosmological constant $Λ_{\rm obs}$ argues that this value promotes the formation of stars, planets, and ultimately of observers such as ourselves. I show that a recent analytic model of cosmic star formation predicts that although $Λ_{\rm obs}$ maximises the overall efficiency of star formation in the universe, the probability of generating observers peaks at $\sim400-500 \, Λ_{\rm obs}$. These preliminary results suggest that an immediate connection between star formation efficiency and observers' generation is not straightforward, and highlight the subtleties involved with the application of anthropic reasoning.
