Essan Posted August 1, 2020 #1 Share Posted August 1, 2020 The final nail in the coffin of the "Clovis Comet" hypothesis? Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor. Michael Waters, director of The Center for The Study of the First Americans and Distinguished Professor at Texas A&M University, and colleagues from Baylor University and the University of Houston have had their work published in Science Advances. Some researchers believed the event -- which cooled the Earth by about 3 degrees Centigrade, a huge amount -- was caused by an extraterrestrial impact with the Earth, such as a meteor collision. But Waters and the team found that the evidence left in layers of sediment in Hall's Cave were almost certainly the result of volcanic eruptions. https://www.sciencedaily.com/releases/2020/07/200731180717.htm 1 2 Link to comment Share on other sites More sharing options...
Piney Posted August 1, 2020 #2 Share Posted August 1, 2020 1 hour ago, Essan said: The final nail in the coffin of the "Clovis Comet" hypothesis? That coffin was nailed shut a long time ago. Especially since every strewnfield cited can be connected to a earlier or later impact and a whole bunch of people were caught lying in their papers. 3 1 Link to comment Share on other sites More sharing options...
Poncho_Peanatus Posted August 4, 2020 #3 Share Posted August 4, 2020 could there be a impact followed by vulcanism? Link to comment Share on other sites More sharing options...
