New Discoveries in the Younger Dryas Impact Hypothesis (Video)

In this 30 June 2025 premiered video, host Randall Carlson talks about the new research which continues to support one of the most controversial theories in Earth history: that a cosmic impact around 12,800 years ago triggered a global catastrophe known as the Younger Dryas event — and wiped out an advanced civilization in the process.

In this episode of Squaring the Circle, Randall Carlson explores the latest discoveries from sediment cores, meltglass, microspherules, platinum anomalies and black mats — all pointing to a massive impact which reshaped our planet, our climate and possibly our memory of what came before.

This wasn’t just a cold snap — it was a planetary reset.

Topics Include:
– New geologic data from North America, Greenland, and South America
– Black mat layers and elevated impact markers
– Ancient flood myths as historical memory
– Civilizational collapse and the Great Forgetting
– How mainstream science is finally catching up

Was there a lost civilization before the Younger Dryas? Did humanity restart history from zero? And could it happen again?
