10: A downed 11,000-year-old comet

So, way, way, way back, 11,000 years ago, a comet may or may not have crashed to Earth and landed deep on the ocean floor, right beneath where the Bermuda Triangle lies today.

Some theorists speculate that this comet might have strange electromagnetic properties that could disrupt compasses and other navigational tools and even interfere with an aircraft engine. So, has anyone found such a comet?

No … or, well, not YET, but the ocean in the area can be tens of thousands of feet deep in some trenches, so proof may never be found. With no proof, faith in an ancient alien comet is really all that's left.

9: Pirates

That's right, pirates.

This region, just north of the Caribbean in the Atlantic Ocean, is totally pirate territory …um, remember Pirates of the Caribbean? We rest our case.

But seriously, piracy really has been a consistent problem in the Triangle for hundreds of years. Now, stir in some good old-fashioned myths about supernatural phenomenon and it's just that much easier for a wily pirate to get away with it ("Who? Me? Blame it on the ghosts...or the aliens.").

While piracy wouldn't account for the aircraft disappearances, it might explain some of the ships that went missing over the years (and also, any treasure you might find buried on the ocean floor).

8: Methane hydrates

Deep beneath the surface of the Bermuda Triangle lie pockets of trapped methane gas, just waiting to be unlocked by seismic activity or underwater landslides. If unleashed, the theory goes, this methane gas could bubble to the surface, reducing the density of the water.

Any ship in that patch of water would lose its buoyancy and sink perilously. It gets worse: In theory, if enough of the flammable gas bubbled up to the surface and got high, high, high up into the air, it could potentially stall an airplane engine or even be ignited by an engine's spark.

It's important to note that the Bermuda Triangle is far from the only place on the planet where methane hydrates exist - it's not even the area with the highest concentration - but it is possible that these hydrates could pose a threat.

Now, would their eruption be powerful and forceful enough to sink a ship or down a plane? We'll leave that one up to you.

7: Time vortex, aka "electronic fog"

So, this theory arises mostly from a single incident.

Here's the story: In 1970, Floridian pilot Bruce Gernon and his father were en route from Andros Island to Bimini Island in the Bahamas when they came across a strange cloud that they say grew exponentially before morphing into a tunnel.

Now, would you fly straight into a spinning, tunnel-shaped cloud? Gernon did.

He flew into that rotating vortex, he says, only to emerge in a thick "electronic fog" with a white haze surrounding the plane. His compass spun wildly and electrical sparks surrounded him.

When the fog finally broke up, Gernon says he found himself miles away from where he expected to be - and much farther than he could have traveled in that time, leading him to believe he had passed through a time travel tunnel.

So, was the "fog" a natural occurrence? Was it due to UFOs, caused by interference from extraterrestrial technology?

Well, anything is possible.

6: Government testing

That darn government.

They really are out to get us, aren't they? And they're so secretive about it.

Forget Area 51; they call this base AUTEC (for Atlantic Undersea Test and Evaluation Center). It's located on the Bahamas' Andros Island, right in the middle of the Bermuda Triangle, and it's where the Navy tests out subs, weapons and sonar…but some people think that's not all they test out.

A handful of theorists insist that our government has been working with extraterrestrials and that AUTEC is actually a testing ground for reverse-engineered alien technology.

Might this advanced alien technology be powerful enough to down planes?

5: UFOs/Aliens

A downed spaceship lurking deep underwater, its dangerous alien mechanics interfering with our own technology? Perhaps. Or perhaps the Bermuda Triangle, along with another similarly rumored triangle in the Pacific off the coast of Japan, serves as a portal for interplanetary, interdimensional creatures.

Not kidding.

That's the theory.

This particular myth holds that human ships and planes, when caught in the portal at the wrong time, end up trapped in between dimensions - it's all just an unintentional by-product of your average day-to-day alien interplanetary, interdimensional, time portal transport.

And you thought your commute was dangerous.

4: Atlantis

For those of you who believe in the legendary underwater city of Atlantis, this one may actually hold some water (no pun intended).

Those who believe Atlantis once lay deep beneath the Bermuda Triangle argue that the remnants of the intense energy crystals that were once used to fuel the city are now interfering with airplane and ship electronics, causing them to go haywire.

Their proof? Sometime in 1970, a scuba-diving Atlantis proponent claims he found a mirrored pyramid of some type, deep under the Atlantic, somewhere around the Bahamas.

Um …well, yeah, if he really did find that, then, sure, most likely something's going on…but the guy seems to have forgotten his underwater camera, let us say.

Other theorists have even more evidence, pointing to what they say is obvious, more easily seen evidence: the Bimini Road, a strange rock formation composed of uniform, seemingly sculpted towers of rock just of the coast of the Bahamian island of Bimini.

The Atlantis proponents claim it was once a dock; geologists claim it's the work of natural forces.

Hmm…so, naturally occurring, interesting-to-look-at rock formation or underwater port? You be the judge.
