Swedish seafaring treasure hunters Ocean X Team made headlines last year with the accidental discovery of a mysterious circular object at the bottom of the Baltic Sea. Now, thanks to more exploration and a laboratory analysis of stones on and around the object, they’re a step closer to lifting the veil on the mystery. The stones that lay on the object turned out to be red granite which came with the ice age. Ocean X Team member Dennis Åsberg’s theory is when the ice melted, the stones landed on the object. That would mean it should have been there more than 140 000 years. Recent examination of the object has revealed a hole about two meters in diameter and that the object is not anchored to the ground. [Dennis Åsberg, Ocean X Team]: “We have discovered that the object is separated from the ocean floor it’s laying on a ridge, we’ve investigated the object with the ROV robot and looked at the object from below. One can see that the bottom and the object is separated. ” Ocean X Team have now made their third expedition to the mysterious object. The material of the object is too hard, so it has not been possible to remove anything from it yet, says Dennis. But they have managed to bring up some stones that have been on and around the anomaly for analysis. The team have also found many black magma-like stones at the site. Dennis’ theory is that the object must have been at a very high temperature at some point. This caused stones in its vicinity to become charred. Dennis …
