Ultra Long-Term Cosmology and Astrophysics
arXiv:2209.06572 · doi:10.1016/j.newast.2022.101940
Abstract
We examine astronomical observations that would be achievable over a future timeline corresponding to the documented history of human civilization so far, 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 years. Implications for several measurements related to gravity are discussed.
