Skeptics expected that a deep-water dive would debunk the slew of extra-terrestrial theories surrounding an unidentified object sitting at the bottom of the Baltic Sea.
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"
'First we thought this was only stone, but this is something else,' diver Peter Lindberg said in a press release.
At the center of the object, which has a 60-meter diameter, 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.
