论文摘要

我们研究了天文观察,这些观察结果将在与人类文明的未来时间表中可以实现,到目前为止,$ \ sim 10^4美元。我们研究了对红移漂移,CMB演变和宇宙视差的含义。在几个世纪的规模上很少发生的许多事件将在时间尺度$ \ sim 10^4 $年中很容易观察到。讨论了与重力相关的几种测量的影响。

We examine astronomical observations that would be achievable over a future timeline corresponding to the documented history of human civilization so far, $\sim 10^4$ years. We examine implications for measurements of the redshift drift, evolution of the CMB, and cosmic parallax. A number of events that are rare on the scale of centuries will become easily observable on a timescale $\sim 10^4$ years. Implications for several measurements related to gravity are discussed.
