Or their smokin' habits.

How can they tell with erosion and all that over the years?

Hmmm it rings a bell, like the moon

They are seismometers on the moon placed by the Apollo missions.They have used modern computing power to get information out of the 5 years of transmitted data that was hidden by noise. The moon still has molten areas according to the results.

Young Moon Creationism?

So the volcanism of the Moon killed the dinosaurs? :)

“..............We’d be much more certain in our understanding of the sequence of geological events on the Moon and other planets if we had more samples collected from many different units that are widely spaced in time. It is largely for this reason (among others) that sample return is always a high priority on the “wish lists” of missions compiled by planetary scientists. Unfortunately, such missions are very difficult to conduct because you have to get into (and then out of) the large gravity well of a planet, which makes the mission very expensive. Several groups are investigating alternative means of getting this information – less costly concepts that will enable sample return and remote measurement of absolute ages on other planetary surfaces. If these other means are successful, we may yet be able to obtain the critical information needed to better understand the history of the Moon and planets.”
