Explanation

The Alvarez hypothesis proposes that a massive asteroid impact (approximately 10 km wide) struck Earth 66 million years ago, creating global catastrophic conditions (dust cloud, temperature drop, ecosystem collapse) that led to the extinction of dinosaurs and many other species. This theory is supported by the iridium anomaly in the geological record and the Chicxulub crater in Mexico.
