The Baltic Sea Anomaly
In 2011, sonar images captured a peculiar, disk-shaped object on the Baltic Sea floor. Measuring 200 feet wide, its unusual features sparked comparisons to a UFO. While some believe it’s a natural rock formation, others suggest it’s an artificial relic from a lost civilization. The anomaly remains a mystery, intriguing scientists and conspiracy theorists alike.
Apollo 11 Engine Debris
In 2013, Amazon’s Jeff Bezos funded the recovery of engines from NASA’s Apollo 11 mission. Located three miles deep in the Atlantic, these F-1 rocket engines powered the Saturn V rocket that took humanity to the Moon. Restored and displayed in museums, the engines are a testament to human ingenuity and exploration, preserved beneath the ocean for decades.
Lake Michigan’s Stonehenge
Beneath Lake Michigan, researchers discovered a circular arrangement of stones resembling England’s famous Stonehenge. Among the rocks, carvings of mastodons suggest the site dates back over 10,000 years. While its purpose remains unclear, the discovery sheds light on ancient cultures that once thrived in North America. This freshwater mystery continues to fascinate archaeologists and historians.
