Wow thank you guys so much (both ichoria and indolering) for your posts! It would be nice to have some links to where you got some of the more technical stuff like where you got this information:
And how they measured the vibration if there are no sound waves in a vacuum?
Quote:They crashed a lunar module causing impact equal to 1 tons of TNT. Shockwaves built up 8 min-rang like a bell 30 min. Another module equal to 11 tons of TNT-the moon reacted like a gong-vibrated three hours and 20 min to a depth of 25 km. The moon wobbled very precisely as if it had big hydraulic dampers struts. The moon was hit by a meteor equivalent 200 tons of TNT-massive shockwaves deep into the interior...... but none came back!!
