So was the 'Baltic Sea UFO' an alien saucer or an underwater Nazi base?
No – it ‘is just rocks’, claim debunkers
- Object ‘is raised about 10 to 13ft above seabed and curved at the sides like a mushroom’
- Theories on origins range from downed UFO, to forgotten World War II base, or meteorite
- But experts say rock samples point to natural rock formation
Since its discovery at the bottom of the Baltic Sea in May 2011, the anomaly has fascinated observers.
The apparently man-made object sits at the bottom of the ocean, looking for all intents and purposes like a drowned Millennium Falcon from the Star Wars movies.
Theories have ranged over its purpose since the Ocean X Team discovered the object on sonar scans.
To some observers, it is a UFO – The ‘Roswell of the Ocean’, while others speculate that it is a Nazi anti-submarine defence, or a plug to the underworld.
But according to one expert, the ‘strange’ and ‘mysterious’ object, as described by the team who found it, is nothing more than glacial rocks that have been dragged across the ocean floor.
Volker Brüchert, an associate professor of geology at Stockholm University, was handed stone samples of the object for analysis.
He said he believed he was seeing nothing more than normal rocks, and told Live Science: ‘It’s good to hear critical voices about this ‘Baltic Sea mystery.
‘What has been generously ignored by the Ocean-X team is that most of the samples they have brought up from the sea bottom are granites and gneisses and sandstones.’
He told Live Science that these are ‘exactly what one would expect to see in a glacial basin, which is what the Baltic Sea is – a region carved out by glacial ice long ago’.
The divers from Ocean X also gave Brüchert a single loose piece of basaltic rock, a type of rock that forms from hardened lava, which he told the website was ‘out of place on the seafloor, but not unusual’.
