What are ocean black holes?
Some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly shielded by circular water paths that nothing caught up in them escapes. Why are there black holes in the ocean? The Black Hole found on the island of South Andros is a large isolated column, about 47m deep and formed by chemical erosion. Its depths replicate ocean conditions billions of years ago.
