7 Most Bizarre Underwater Discoveries Nobody Can Explain
3. The Baltic Sea Anomaly
More than 90 metres beneath the waves of the Baltic Sea lies a weird object that resembles the Millennium Falcon from the Star Wars movies.
Referred to as the Baltic Sea Anomaly, the strange circular entity was discovered by Swedish explorer Peter Lindberg and his Ocean X team in June 2011.
Conspiracy theorists leaped on the find and hailed it as proof aliens have visited Earth, and for five years, few other explanations for the phenomenon presented themselves.
This year, scientists from Stockholm University carried out analysis on samples carved from the Baltic Sea Anomaly and concluded that it is simply a glacial deposit, but Lindberg isn't satisfied with that conclusion, pointing out that it doesn't explain why all of his electrical equipment cut out when he arrived in the object's vicinity.
