AI 中文总结

该模型将各类渐近dS宇宙置于最大熵平坦FRW宇宙的黑洞内,论证其衰变平衡时间远短于dS重现时间,且内部探测器无法判断自身所属结构,可用于解释自然常数或宇宙初始条件的取值。

AI 中文摘要

我们提出一个模型,其中各类渐近德西特(de Sitter,dS)宇宙及德西特半径Rₙ,均存在于最大熵平坦p=ρ弗里德曼-罗伯逊-沃克宇宙内的黑洞内部。这些dS宇宙显然具有大量量子态。我们论证,它们会以量级为αₙRₙln(Rₙ/δₙ)的时间尺度衰变并与最大熵宇宙达到平衡,其中αₙ是与模型相关的无量纲常数,δₙ是满足以色列接合条件的壳层与dS视界之间的初始距离。这些时间是沿远离假想宇宙视界的轨迹运动的探测器所观测到的时间,且均远短于dS重现时间(在该模型中无意义)。位于某个dS宇宙内部的探测器无法确定自身是否属于此类结构。该模型可作为一种依据,主张某些自然常数或宇宙初始条件被选择为数学上非自然的值,因为其他值无法产生任何形式的智慧生命。

英文摘要

We present a model in which asymptotically de Sitter universes of various types, and de Sitter (dS) radii $R_n$, live in the interiors of black holes in a maximally entropic flat $p = ρ$ Friedmann-Robertson-Walker universe. These dS universes clearly have many quantum states. We argue that they decay and equilibrate with the maximal entropy universe on time scales of order $α_n R_n {\rm ln} (R_n /δ_n)$, where $α_n$ are model-dependent dimensionless constants and $δ_n$ are the initial distances between the shell, satisfying the Israel junction conditions, and the dS horizon. These are time-scales as viewed by a detector following a trajectory far from the would-be cosmological horizon. These times are all exponentially shorter than dS recurrence times, which have no meaning in this model. It is impossible for a detector inside one of the dS universes to determine whether it is actually part of such a structure. This model could be used as the basis for claiming that certain constants of nature or cosmological initial conditions were chosen to have mathematically unnatural values because other values could not lead to any form of intelligent life.
