In 2000, Discover Magazine published a list of 20 possible sudden doomsday scenarios with impact event listed as the No. 1 most likely to occur. Until the 1980s this idea was not taken seriously, but opinions changed following the discovery of the Chicxulub Crater, which was further reinforced by witness to the Comet Shoemaker-Levy 9 event.

Famous quotes containing the word civilization:
“Never before since Jamestown and Plymouth Rock has our American civilization been in such danger as now....
