How do eclipses relate to flat earth theory though? Those explanations seem to be for globes.
Eclipses really do happen. Even the FE'ers cannot deny that. Nearly everyone will have seen a Lunar eclipse - they happen frequently. Millions of people across the USA saw the 2017 total solar eclipse.
The RET explanation for them is very simple.
* In a solar eclipse, the moon goes in front of the sun and hides it.
* In a lunar eclipse the Earth gets between the sun and moon and the Earths' circular shadow is cast onto the moon.
The FET explanation is (as usual) considerably more tortured!
* In a solar eclipse, the moon goes in front of the sun and hides it - but because sun and moon are claimed to be identical in size - the moon must be implausibly close to the sun at the time.
* In a lunar eclipse, the Earth isn't involved (can't be because both sun and moon are above the plane of the earth so it can't cast a shadow onto the moon) - so they've invented a third body called "The Shadow Object" (or some say "The Anti-Moon") which is orbiting close to the sun and casts it's shadow onto the moon during a lunar eclipse. The shadow object somehow manages to be 100% indetectable by all possible means for the rest of the time. It doesn't create tides, it doesn't block out stars or planets like Venus and Mercury, it never gets in front of the sun, it doesn't cast a shadow onto stars or planets during the lunar eclipse. But the claims required to make it be so perfectly hidden at ALL other times get very complicated and hard to swallow. It seems like a really contrived thing...which, of course, it is!
