The Bermuda Triangle is a region in the western part of the North Atlantic Ocean in which ships and planes have disappeared under mysterious circumstances. It is roughly bounded by Miami, Bermuda, and Puerto Rico. Some people believe that the Bermuda Triangle is a mysterious and dangerous area, but there is no scientific evidence to support this idea. Many theories have been proposed to explain the mysterious disappearances that have occurred in the Bermuda Triangle, but none of them have been proven.
