The Bermuda Triangle does indeed have unusual qualities, as do other places here and there on Earth. Magnetic anomalies are reported, where compasses swing wildly, clocks stop, and concrete objects fade from sight. What's causing this? These places, fortunately few in number, are an outlet from the center of the Earth for a byproduct of the Earth's compression, a gravity byproduct so to speak. A vent, from where subatomic particles not known to man surge forth periodically, and woe be to the man or fish who finds itself in the way. There are stories of ships and planes disappearing, and it is assumed they were carried off by extraterrestrials, taken off to a far-off zoo, for exhibition. Then why would these only disappear from such sites, and not regularly around the globe?
Here and there around the face of the Earth are similar outlets for this byproduct of the Earth's compression, many of them well known due to the havoc shippers or travelers experience - an area off the coast of Japan, and in one of the Great Lakes, for example. Such outlets also occur where man is unaware of them, as in the depths of the oceans or within inaccessible mountain crevices. What determines the outlet is not only the surface structure of the rock, fractures in fact, but also the structure of the underlying rock, factors man cannot measure.
