That mushroom cloud? A 50-megaton hydrogen bomb—the largest explosion ever created by humans. Now imagine something 12 times more powerful... flying past Earth. That’s the kind of force we’re dealing with when it comes to cosmic impacts. Nature plays by different rules. | The Randall Carlson

In 1908, Tunguska exploded over Siberia with the force of a 15 megaton hydrogen bomb—and it likely wasn’t an asteroid… but a fragment of a comet.
