Tunguska Explosion

On June 30, 1908, a massive explosion rocked the remote forests of Siberia, flattening an estimated 80 million trees over a vast area. Surprisingly, despite the scale of the event, no immediate scientific investigation followed, leaving the mystery unsolved for years. It wasn't until a geologist ventured into the region in 1921 that the first clues emerged, revealing a lack of a crater or meteor fragments, challenging conventional expectations of such a cataclysmic event.
