The Moon is almost Earth’s isotopic twin, though it formed from the debris of an alien planet. The riddle solves simply: as the lunar magma ocean solidified, Theia’s heavy rocks sank, while Earth’s lighter ones floated up and hardened on top. So our satellite is just a pretender with an extraterrestrial gut.
🎯 If astronauts drilled deep enough into the Moon, they’d hit a layer with a completely alien chemistry — a real hello from vanished Theia.
🎬 Like in Jules Verne’s ‘Journey to the Center of the Earth,’ the Moon might harbor another world inside — not fictional, but a real shard of a vanished planet.
