Earth ChangesMore Evidence Supporting Younger Dryas Impact Hypothesis Emerges Posted on August 13, 2025 by Administrator Deep beneath the frigid waters of Baffin Bay near Greenland, microscopic grains of alien dust have been discovered that provide startling new evidence for one of archaeology’s most controversial theories. A study published in PLOS One has uncovered geochemical signatures of a comet explosion that rocked Earth 12,800 years ago, offering the second major scientific validation in recent weeks for the Younger Dryas Impact hypothesis. This ocean-floor evidence adds to the growing body of terrestrial impact markers found worldwide.
