But the Swedish expedition team that took the plunge surfaced with more questions than answers and certainly no solution to its origins.
The divers found that the object, which some have likened to the Millennium Falcon because of its unusual round outline, was raised about 10 to 13ft above the seabed and curved in at the sides, giving it a mushroom shape.
They added that the object has ’rounded sides and rugged edges’
At the center of the object, which has a 60-meter (197 feet) diameter, it has an “egg shaped hole leading into it from the top”.
Surrounding the hole, they found a strange, unexplained rock formation. Adding fuel to the speculative fire, they said that the rocks looked “like small fireplaces” and the “stones were covered in something resembling soot”.
“Since no volcanic activity has ever been reported in the Baltic Sea the find becomes even stranger”, Mr Lindberg continued.
The soot also proved cause for concern for Mr Lindberg’s colleague on the Ocean X explorer team, Stefan Hogeborn.
“During my 20-year diving career, including 6,000 dives, I have never seen anything like this. Normally stones don’t burn”, Mr Hogeborn said in the release.
“I can’t explain what we saw, and I went down there to answer questions, but I came up with even more.”
The object was first found in June last year, but because of a lack of funding and bad timing, they have were not able to pull a team together to see for themselves – just the strange, metallic outline, and a similar disk-shaped object about 650 feet away.
As it was before the recent dive, the story behind the object is anyone’s guess.
“We’ve heard lots of different kinds of explanations, from George Lucas’s spaceship – the Millennium Falcon – to ‘it’s some kind of plug to the inner world,’ like it should be hell down there or something”, Mr Lindberg said.
Speaking to Fox News, he said: “We don’t know whether it is a natural phenomenon, or an object. We saw it on sonar when we were searching for a wreck from World War I. This circular object just turned up on the monitor.”
While the Ocean Explorer team is understandably excited about their potentially earth-shattering find, others are slightly more sceptical and are questioning the accuracy of the sonar technology.
In the past, such technology has confused foreign objects with unusual- but natural- rock formations.
Part of the trouble they face, however, is that they have no way of telling what is inside the supposed cylinder- whether it is filled with gold and riches or simply aged sediment particles.
The Baltic Sea is a treasure trove for shipwreck hunters, as an estimated 100,000 objects are thought to line the cold sea’s floor.
The company have created a submarine that they hope will appeal to tourists and wannabe shipwreck hunters who will pay to take a trip down to the bottom of the Baltic Sea to see for themselves.
