Description
Sixty-five million years ago, a massive comet or asteroid collided with Earth, causing an explosion equivalent to a hundred million hydrogen bombs. The impact sent vaporized debris into the atmosphere, which eventually fell back to Earth around the globe, resulting in catastrophic environmental consequences. The disaster included a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half of all plant and animal genera on Earth had perished. This event is now widely accepted as the solution to a long-standing scientific mystery: what caused the extinction of the dinosaurs. Walter Alvarez, one of the scientists who discovered evidence of the impact, tells the story behind the development of this theory in his book. The story is one of high adventure, data collection, and intellectual struggle, with moments of frustration giving way to sudden breakthroughs.
