Everyone loves a good mystery, but sometimes figuring out a mystery can be a challenge. Sometimes there are occurrences that just have no explanation. Here are seven creepy mysteries that science can’t explain.
Giant Stone Spheres
In Costa Rica on the islands of Isla del Cano and Diquis Delta, there are over three hundred circular objects of varying sizes. Known to the locals as Las Bolas, literally translating to ‘the balls’, these spheres have also been called the Diquis Spheres. These nearly perfect round stones range in size and can weigh up to sixteen tons each. Almost all of them seem to be made of granodiorite, but others are limestone or sandstone. And no one really knows where they came from. There are myths that the stones originated from Atlantis, the fabled sunken city, and that they were created by a long-forgotten society. The stones have been studied for years, but the only sure thing is that they are thousands of years old.
