Re: Earth's Gravitation?
"As I understood it, one huge impediment to viable, large, long-term structures on the Moon's surface is Earth's gravitational squishing of the Moon, eg. foundations/roads being broken up."
A bigger issue could be the temperature swings from day to night and back. Cobbles? A vehicle's wheels or tracks would need to handle travel on a cobble road, but we've been doing that for a few years now.
I'm trying to think who to ask about moon squish.
