BERMUDA TRIANGLE

The Bermuda Triangle, also known as the Devil's Triangle, is a region of the northwestern Atlantic Ocean in which a number of aircraft and surface vessels have disappeared in circumstances that fall beyond the boundaries of human error or acts of nature.The more familiar, triangular region formed by points on the Atlantic coast of Florida; San Juan, Puerto Rico; and the mid-Atlantic island of Bermuda, with most of the accidents concentrated along the southern boundary around the Bahamas and the Florida Straits.

There are various reasons stated for the accidents in this mysterious triangular region.
1)extraterrestrial beings
2)Human error
3)Freak waves
4)Gulf Stream--The Gulf Stream is an ocean current that originates in the Gulf of Mexico, and then through the Straits of Florida, into the North Atlantic. In essence, it is a river within an ocean, and like a river, it can and does carry floating objects
5)Hurricanes--Hurricanes are extremely powerful storms which are spawned in the Atlantic near the equator.
6)Compass variations--Compass problems are one of the cited phrases in many Triangle incidents. The North Magnetic Pole is not the North Pole; rather it is the north end of the earth's magnetic field. The North Magnetic Pole does wander, but so slowly that the wandering would not be noticeable on time scale of a sea or air voyage. In general, the compass does not point exactly the direction of the North Magnetic Pole, but rather the compass needle aligns itself to the local geomagnetic field, which can vary in a complex manner over the Earth's surface, as well as over time
7)Methane hydrates--An explanation for some of the disappearances has focused on the presence of vast fields of methane hydrates on the continental shelves. Laboratory experiments carried out in Australia have proven that bubbles can, indeed, sink a scale model ship by decreasing the density of the water, any wreckage consequently rising to the surface would be rapidly dispersed by the Gulf Stream.
