"New study sheds light on moon’s slow retreat from frozen Earth (Astrobiology Magazine).
Students of secular geophysics are aware of two long-standing challenges: the “faint young sun paradox” and the moon’s orbital recession from the Earth.
The latter implies our moon would have been catastrophically close to the Earth in only a fraction of the assumed age of the solar system. This article says the moon is currently receding at 1.56 inches per year. If that rate is extrapolated back in time, it would imply the moon would have pumped enormous energy into the earth. Modelers at the University of Colorado at Boulder are trying to tweak the Snowball Earth hypothesis and the faint young sun paradox to make things work out, but admits in the end that “direct observational evidence in the geological record is currently lacking, making it the subject of debate among scientists.”
