Many people have reported looking up at our satellite, the Moon, and seeing a man's face on the surface. We should start eyeing him with a little more suspicion, because he's trying to escape. With every passing year, the Moon is a little bit further away from us.
Because of the interaction between the Moon and the Earth's tides, the Moon is experiencing a very gentle repulsion. The Moon's gravity causes the tides in the first place, but the tides in turn generate a 'tidal bulge', generation friction during the rotation of the Earth that, in turn, pushes back against the Moon. Its current rate of retreat is 1.5 inches per year - about the same speed your fingernails grow - so we don't need to worry about it disappearing just yet. That's just as well really - without it, the Earth may stop spinning completely.
