An impact event is commonly seen as a scenario that would bring about the end of civilization. Discover Magazine published a list of 20 likely end of the world scenarios with impact event listed as the number one most likely to occur. Until the 1980s this idea was not taken seriously, but all that changed after the discovery of the Chicxulub Crater which was further reinforced by witness to the Comet Shoemaker-Levy 9 event. Since then there has been more interest from the scientific community and greater public awareness of the possibility of impact events.
