AI 中文摘要
在重新审视休·埃弗雷特的一篇经典文章后,我将从生活在德西特空间中的观察者的视角讨论该空间的熵。这提供了一个很好的例子,说明在某些问题上,认真对待以下事实的重要性:在宇宙学中,任何观察者实际上都是被观察宇宙的一部分。(本文发表于《国际现代物理杂志A》特刊,以纪念杰拉德·特胡夫特。)
英文摘要
After re-examining a classic article by Hugh Everett, I will discuss the entropy of de Sitter space from the standpoint of an observer living in the space. This provides a nice example of the importance -- for certain questions -- of taking seriously the fact that in cosmology any observer is really part of the universe that is being observed. (This article has appeared in a special issue of International Journal of Modern Physics A in honor of Gerard 't Hooft.
