what is the mystery behind the bermuda triangle?

The Bermuda Triangle is a large area of ocean between Florida, Puerto Rico, and Bermuda. Over the last few centuries, it’s thought that dozens of ships and planes have disappeared under mysterious circumstances in the area, earning it the nickname “The Devil’s Triangle.” People have even gone so far as to speculate that it’s an area of extra-terrestrial activity or that there is some bizarre natural scientific cause for the region to be hazardous; but most likely, it’s simply an area in which people have experienced a lot of bad luck—the idea of it being a “vortex of doom” is no more real than Bigfoot or the Loch Ness Monster (see The Origin of the Bigfoot Legend and The Origin of the Loch Ness Monster). The Bermuda Triangle’s bad reputation started with Christopher Columbus. According to his log, on October 8, 1492, Columbus looked down at his compass and noticed that it was giving weird readings. He didn’t alert his crew at first, because having a compass that didn’t point to magnetic north may have sent the already on edge crew into a panic. This was probably a good decision considering three days later when Columbus simply spotted a strange light, the crew threatened to return to Spain. This and other reported compass issues in the region gave rise to the myth that compasses will all be off in the Triangle, which isn’t correct, or at least is an exaggeration of what is actually happening as you’ll see. Despite this, in 1970 the U.S. Coast Guard, attempting to explain the reasons for disappearances in the Triangle, stated: First, the “Devil’s Triangle” is one of the two places on earth that a magnetic compass does point towards true north. Normally it points toward magnetic north. The difference between the two is known as compass variation. The amount of variation changes by as much as 20 degrees as one circumnavigates the earth. If this compass variation or error is not compensated for, a navigator could find himself far off course and in deep trouble. Of course, despite this now being repeated as an explanation for disappearances in the Triangle on numerous documentaries and articles since then, it turns out magnetic variation is something ship captains (and other explorers) have known about and had to deal with pretty much as long as there have been ships and compasses. Dealing with magnetic declination is really just “Navigation by Compass” 101 and nothing to be concerned about, nor anything that would seriously throw off any experienced navigator.
