His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.

This article collects evidences that place a lower limit on the age of the Universe beyond the 6,000 to 10,000 years asserted by most Young Earth creationists (YECs) and the literalist Ussher chronology.

All of this evidence supports deep time: the idea, considered credible by scientists since the early 1800s, that the Earth (and the Universe) is millions or billions of years old.

The heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and free neutrons.
