What If the Moon Disappeared?

What would happen if the Moon simply vanished tonight? We follow the effects step by step: much darker nights, tides shrinking to less than half, corals that lose their spawning clock, lions that hunt better in the dark, sea turtles and dung beetles that lose their guide, a wobblier tilt for planet Earth, days that stop getting longer, and the end of total solar eclipses. Plus why the word "month" comes from the Moon, the Mid-Autumn Festival, the next great eclipse on 2 August 2027, and why the Moon is not actually going anywhere.

Older models said chaotically; a 2011 study says maybe only ~10° more • 1.4 billion years ago a day lasted about 18 hours • Total solar eclipses will end in roughly 600 million years as the Moon drifts away This is a thought experiment. The Moon is not going to disappear.
