Alvarez won the 1968 Nobel Prize in Physics for "the discovery of a large number of resonance states, made possible through his development of the technique of using hydrogen bubble chamber and data analysis". Specifically, his research made it possible to record and study the short lived particles created in particle accelerators.
With geologist son Walter, in 1980, Luis proposed the asteroid-impact theory to explain the iridium anomaly of the K-T extinction boundary. Ten years later, highly convincing evidence was presented showing that a huge impact crater called Chicxulub was, in fact, the "smoking gun" of the K-T boundary. This impact by an extraterrestrial body is now widely accepted as causing the extinction that killed the dinosaurs.
