Answer:
Hi! i'm a bit rusty on this but here's what i remember. There is theory stating that a huge crystal pyramid lies 2,000 meters below the Bermuda Triangle. The theory shares that the pyramid was discovered in 2012, and most think that the crystal pyramid was the cause of the disappearance of many ships and airplanes. A scientist named Dr. Verlag discovered the crystal pyramid, and claimed that it is supposedly three times the size of the Great Pyramid of Giza. Dr. Verlag presented her new discovery at a conference in the Bahamas where she shared the coordinates, but there is no record of the coordinates she had claimed to have announced. Hope this helps!
