Astronomers have been reflecting laser beams off the Moon since reflectors were left there by Apollo astronauts. This has resulted in the conclusion that the Moon is moving away from the Earth at a rate of 3.8 cm per year. Discuss the specific cause of what is making the Moon recede, the likely end result for the Earth-Moon system, and what you think this might mean for life on Earth. .
