Kurt Gödel's incompleteness theorems, published in 1931 in the paper "Über formal unentscheidbare Sätze der Principia Mathematica und verwandter Systeme I," constitute one of the most profound results in the history of l

M_4_09 — Younger Dryas Impact and Lost Civilization Hypothesis

The Younger Dryas Impact Hypothesis (YDIH) proposes that a cosmic impact or airburst event approximately 12,800 years ago (12.8 ka BP) triggered the Younger Dryas cold reversal — a ~1,300-year return to near-glacial cond
