The Bermuda Triangle is a place in the western part of the Atlantic Ocean​ where ships, planes, and people are to have mysteriously vanished. Some say that unknown forces account for the disappearances, such as aliens capturing humans for study, the lost continent of Atlantis; portals that suck objects into other dimensions; and other unlikely ideas. Some explanations are more grounded in science, if not in evidence. The U.S. Navy and U.S. Coast Guard say that there are no weird explanations for disasters at sea. Their experience suggests that the forces of nature and human outdo even the most crazy science fiction. They say that no official maps exist that tell the boundaries of the Bermuda Triangle. The U. S. Board of Geographic Names does not see the Bermuda Triangle as an real name and does not keep an official file on the area.
