Could a comet airburst in 536 AD have triggered the Dark Ages and inspired the Holy Grail legend? ☄️ In this episode of Squaring the Circle, Randall moves beyond previous discussions on the 1908 Tunguska event to examine how near-Earth space—densely populated by asteroids, bolides and cometary fragments—interacts with Earth’s biosphere, climate history and how these modern studies, coincidently, correspond with certain, ancient mythological stories handed down to us by our ancestors.
