The Chicxulub Crater Theory

BOOOOOOOOOMIn the journal Science, in an article titled “Extraterrestrial Cause for the Cretaceous-Tertiary Extinction”, Nobel-Prize-winning physicist Luis Alvarez and his son, geologist Walter Alvarez, propose their theory that the 110-mile-wide Chicxulub Crater discovered in the past few decades on the northern tip of the Yucatan Peninsula in Mexico is evidence of a large asteroid collision with Earth, resulting in the widespread death of the dinosaurs 65 million years before the modern day. A contentious peer review of the published theory follows, with many opposing theories proposed, though the Chicxulub hypothesis is eventually accepted as the “smoking gun” that killed the dinosaurs (the theory of an asteroid collision with Earth causing the extinction had been in circulation since the 1950s; the Alvarez theory is the first to point to a specific geological feature as evidence).
