What killed the dinosaurs? For more than a century, this question has been one of the greatest unsolved mysteries in science.
But, in 1980, Nobel Prize-winning physicist Luis Alvarez and his son, Walter, proposed a radical answer: 65 million years ago an asteroid or comet as big as Mt.
Everest slammed into the earth, raising a dust cloud vast enough to cause mass extinction.
A revolutionary idea that challenged the ice-age extinction theory, the asteroid-impact theory was scorned and derided by the science community.
But after years of bitter debate and intense research, an astonishing discovery was made-an immense impact crater in the Yucatán Peninsula that was identified as Ground Zero.
The Alvarezes had their proof.
A dramatic scientific detective story, Night Comes to the Cretaceous is a brilliant example of science at work-in the trenches, complete with passionate struggles and occasional victories.
