Abstract

We examine astronomical observations that would be achievable over a future timeline corresponding to the documented history of human civilization so far, 104\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 104\sim 10^4 years. Implications for several measurements related to gravity are discussed.
