Looks like the cause of lost of accidents in Bermuda Triangle hadn't been aliens, ghosts nor a deity, the evidence points to methane.
The evidence for this astounding new insight into a mystery that's bedeviled the world is laid out in a research paper published in the American Journal of Physics.
Professor Joseph Monaghan researched the hypothesis with honor student David May at the Monash University in Melbourne, Australia.
The two hypothesized that large methane bubbles rising from the ocean floor might account for many, if not all, of the mysterious disappearances of ships and aircraft at specific locales around the world.
Researcher Ivan T. Sanderson identified these mystery areas during the 1960s. Sanderson described the actual shape of these regions as more like a lozenge rather than a triangle. Some of the more famous spots include an area in the Sea of Japan, the North Sea, and of course the infamous "Bermuda (or Devil's) Triangle."
Oceanographic surveyors of the sea floor in the area of the Bermuda Triangle and the North Sea region between continental Europe and Great Britain have discovered significant quantities of methane hydrates and older eruption sites.
The methane—normally frozen at great pressure as gas hydrates embedded within subterranean rock—can become dislodged and transform into gaseous bubbles expanding geometrically as they explode upwards. When these bubbles reach the surface of the water they soar into the air, still expanding upwards and outwards.
Any ships caught within the methane mega-bubble immediately lose all buoyancy and sink to the bottom of the ocean. If the bubbles are big enough and possess a high enough density they can also knock aircraft out of the sky with little or no warning. Aircraft falling victim to these methane bubbles will lose their engines-perhaps igniting the methane surrounding them-and immediately lose their lift as well, ending their flights by diving into the ocean and swiftly plummeting to the sea bottom.
To provide a check on the accuracy of their hypothesis, the two scientists built a large tank, filled it with water to simulate the regions of the earth where ships and planes have reportedly disappeared over the last century, and launched large methane gas bubbles from the bottom of the tank towards a toy ship floating on the surface of the water.
The results were impressive and the physical tests mirrored the computer model. The two found that the ship sank if it was between the middle of a bubble and its outer edges. If the ship was far enough away from the edge of the bubble—or directly over it—the ship would sail on safely. Despite not sinking, however, if the methane bubble was big enough and the ship was positioned at or near the center of the bubble when it surfaced, every one on the ship could be asphyxiated. This would account for several famous cases where ships were found in the Triangle with everyone aboard dead without a scratch.
Monaghan and May also discovered some surprising properties of a methane bubble when it interacts with a ship. The two had assumed that as a bubble broke the surface it would burst, creating a depression. They envisioned a ship falling into the depression, riding through it and coming through basically unscathed. The tests revealed something entirely different.
As a bubble surfaced the water rose dramatically creating a sphere of water. Yes, the ship would slide off the sphere, but as the bubble burst a huge jet or column of high-velocity water would slam onto the ship and in a matter of seconds drive it down into the murky depths.
Recent surveys in the North Sea region have identified sunken vessels that are very near previous methane venting/eruption sites. What a methane bubble would actually look like, however, as it roars from the ocean depths breaking onto the surface of the sea no one knows.
Anyone who has experienced the phenomenon first-hand is dead.
