Hancock places the Younger Dryas catastrophe at about 12,800 years ago and argues that it was triggered by a cosmic impact or airburst. He cites the 1908 Tunguska airburst, which flattened roughly 2,000 square kilometres—about 770 square miles—of Siberian forest, and Randall Carlson’s estimates of impact frequency over the past million years. He compares humanity’s situation to crossing a highway with its eyes closed and argues that NASA is not investigating the so-called “torrid meteor stream,” which he calls our most immediate cosmic threat. 🌍
Hancock links Younger Dryas and Tunguska to cosmic impact risk
Key facts
- Hancock dated the Younger Dryas catastrophe to 12,800 years ago and claimed it was implicated in cosmic impact.
- He cited the 198 Tunguska event, saying a meteorite from a cited 'torrid meteor stream' devastated about 2,000 square miles of forest in Russia.
- He noted Randall Carlson's work on the frequency of impacts over the last million years.
- Hancock said an object on an Earth-crossing orbit is expected to pass close and described humanity as crossing a highway with eyes closed.
- He claimed NASA is not investigating the so-called torid meteor stream, which he calls the most immediate cosmic threat.
