Antarctica Hit by Catastrophic Meteors, Researchers Claim

first_imgA story in BBC News claims that multiple impact sites have been found under Antarctic ice covering an area 1300 by 2400 miles, with one impact making a hole in the ice 200 miles across.  The estimated date of these impacts (around 780,000 years ago) creates a problem, however:The research suggests that an asteroid the size of the one blamed for killing off the dinosaurs 65 million years ago could have struck Earth relatively recently.    Early humans would have been living in Africa and other parts of the Old World at the time of the strikes.If such a destructive impact killed off dinosaurs, how could the humans and other mammals survived?  A suggestion was quickly forthcoming: “But the impacts would have occurred during an ice age, so even tidal waves would have been weakened by the stabilising effect of icebergs on the ocean.”For an ad hoc just-so story to explain away evidence against a popular theory, this one takes the cake.  These theorists seem to have been hit with a rock on the head.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img
