If there's one place that is still full of wonder, containing many different mysteries, it's probably the bottom of the ocean. The deep, dark depths are a final frontier of sorts, and there is still much to see down there. As an example of what's potentially waiting for us thousands of leagues under the sea, I'd like to introduce you to the so-called Baltic Sea Anomaly...
The Baltic Sea Anomaly is an unidentified structure that was discovered via sonar and radar by a Swedish diving team back in 2011.
Conspiracy theorists postulate that the UFO must have crashed sometime during the Ice Age, though they aren't certain why it's there.
Sadly there is an extreme lack of evidence to support these claims. Rock samples of the structure collected by the Swedish diving team found nothing anomalous about the structure.
