A bizarre sphere has been found in the forest near Zavidovići, Bosnia, and some speculate that it's an artifact that was left behind by an ancient civilization. Archaeologist Semir Osmanagić thinks that this strange find could be part of a series of several other spheres that were sadly destroyed by treasure hunters decades ago. If that's true, then this one could be 1,500 years old. Here's the ball in question. It's approximately 5 feet in diameter and it has a high iron content.

Unfortunately for Semir Osmanagić, the scientific community isn't convinced that the sphere was created by humans. Mandy Edwards of the University of Manchester believes that the roundness could be attributed to erosion. Dr. Osmanagić is no stranger to controversy. In 2005, he claimed that he discovered ancient pyramids in Bosnia's Visoko Valley, and the European Association of Archaeologists basically called him crazy because of it. I have to hand it to him, though. His theory about this sphere is way cooler than the alternative.
