On November 20, 1969, Apollo 12 deliberately crashed its Ascent Stage of its Lunar Module onto the moons surface and the moon rang "like a bell" for an hour. The moon has hollow catacombs with a metal shell around it and 3 to 4 miles of mantel dirt/crust above it. Juan O' Savin has talked about this with Tom Numbers on one of his shows called "Moon: Is The Forbidden Planet". If the earth rang like a bell then is it a similar construct to the moon? 🌏 🌙
