Fact Check: Comet Theory Links Ice Age End to Megafauna Extinctions, but Timing Fails
A new fact check clarifies the Younger Dryas impact hypothesis. While a sharp cold spell and platinum spike in Greenland ice are established, the claim that a comet caused it is disputed. The idea that this event ended the Ice Age is fringe, as the Ice Age ended 1,200 years later. Claims of a wiped-out advanced civilization remain unverified due to lack of archaeological evidence.
