👉 In the context of astronomy, a "pseudepigraphical period" refers to a time or event that is not historically recorded or known. It could be used to describe a hypothetical event that was never observed in the real world but is believed by some scientists to have occurred before our own era. For example, a pseudepigraphical period might refer to an event that has been widely accepted as part of the historical record but that has not yet been officially recorded or documented.
