The Explosion That Flattened 2000 Square Miles

[00:00:00]June 30th, 1908. A fireball streaked across the Siberian sky. Then came the explosion. The blast was heard 400 miles away. It flattened 2,000 km of forest, the power of 185 atomic bombs. But when scientists finally reached the site 19 years later, they found something impossible. No crater, no meteorite fragments, nothing. Just 80 million trees knocked down in a perfect pattern, all pointing away from ground zero like fallen dominoes. Witnesses described a column of fire that split the sky. The shock wave circled the Earth twice. If it had happened just 4 hours later, St. Petersburg would have been wiped off the map. What could cause such devastation and leave no trace? Scientists have theories. An asteroid that vaporized midair, a comet made of ice. Some even suggested antimatter. But after more than a century, the Tungusa event remains unexplained. The most powerful mysterious explosion in recorded history. And we still don't know what caused it.
