Abstract
We demonstrate that as we extrapolate the current АCDM universe forward in time, all evidence
of the Hubble expansion will disappear, so that observers in our “island universe” will be
fundamentally incapable of determining the true nature of the universe, including the existence
of the highly dominant vacuum energy, the existence of the CMB, and the primordial origin of
light elements. With these pillars of the modern Big Bang gone, this epoch will mark the end of
cosmology and the return of a static universe. In this sense, the coordinate system appropriate for
future observers will perhaps fittingly resemble the static coordinate system in which the de Sitter
universe was first presented.
