Ships, planes, and people are said to have inexplicably vanished in the Bermuda Triangle, which is located in the western North Atlantic Ocean. The three points of the "triangle" are typically identified as Miami, Puerto Rico, and the island of Bermuda, though descriptions of its bounds vary. According to one theory, the Bermuda Triangle area has a parallel universe that causes a time/space warp that pulls objects nearby into the parallel reality. Others say UFOs were involved in the occurrences. Author of several books on anomalous occurrences Charles Berlitz provides a list of theories that link the losses in the Triangle to anomalous or inexplicable causes.
