There are good reasons to think that Earth has turned over on various occasions. But who can be surprised that this perception—so removed from everyday experience—seems less than instantaneously persuasive?
The good reasons include telling evidence in narrative testimony and correctly interpreted myths of the ancients, embedded patterns in ancient cultures that give evidence of inversions, and the insights and arguments of two formidable researchers. Now we can: add new reasons that strengthen the case; specify the approximate dates of four inversions; extend the theory to the five great mass extinctions of prehistory; comprehend that Earth is actually prone to inversion; and point to where to find more evidence. Understanding inversions helps us correct errors in interpreting past planetary and Earth science while providing clues relevant to climate change.
