The Antikythera mechanism is an Ancient Greek hand-powered orrery, described as the oldest known example of an analogue computer used to predict astronomical positions and eclipses decades in advance. Its construction relied on theories of astronomy and mathematics developed by Greek astronomers during the second century B.C. Some argue that comparable technology didn't begin appearing until centuries later, and thus it's existence may be proof of time travel. Was this device actually brought back to ancient Greece and left there on purpose for us to discover?
