The relative sizes are approximate, not perfect, but close enough that our monkey brains interpret it as more than a coincidence.
replyIdk, one could come up with a hypothesis that eclipses provide the first tangible validation of a system of mathematics.
replyIf there were greater significance to it, I’d have thought the the visual sizes of the Sun and Moon would have been perfectly matched, rather than to within a few percent, give-or-take.
replyAlso since the Sun-Earth distance varies and so does the Earth-Moon distance, the coverage of the Sun varies. We sometimes get annular eclipses where the Sun is not totally covered.
