  Consider the scenario, in which human civilization undergoes periodic eras of
progression and regression, and consequently, changes in cosmological knowledge
are cyclic. There exist solutions of general theory of relativity, such as the
G\"{o}del universe, in which the cosmos is rotating. If the real universe is
indeed rotating, than this would be a reversion to rotating universe models,
used in ancient cosmological models. We argue that such reversions in physical
models would be inevitable in a space-time in which time is having $S^1$
(circular) topology.
