Maybe off topic, but how did they age the rocks on the moon. Too old for C14, no fossils for geo column dating. How'd they get the age?

There are a number of other radioactive isotopes with longer half-lives that can be used. For example, K-40 has a half-life of 1.25 billion yrs and can be used for rocks with ages 100,000-4.6 billion yrs.
