Some unresolved mysteries of the world ...

..you may never have heard of.

Sailing stones

The sailing stones, also known as sliding rocks, are a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention. They have been recorded and studied in a number of places around Racetrack Playa, Death Valley, where the number and length of travel grooves are notable. The force behind their movement is not understood and is the subject of research.
Sliding rock trails fluctuate in direction and length. Some rocks which start next to each other start out traveling parallel, but one may abruptly change direction to the left, right, or even back the direction it came from. Length also varies because two similarly sized and shaped rocks could travel uniformly, then one could burst ahead or stop dead in its track. Speed is also an unknown variable

Marfa Lights

The Marfa lights or the Marfa ghost lights are unexplained lights (known as “ghost lights”) usually seen near U.S. Route 67 on Mitchell Flat east of Marfa, Texas, in the United States. Sightings are reported occasionally and unpredictably, perhaps ten to twenty times a year.
The first published account of the lights was written in 1957, and this article is the sole source for anecdotal claims that the lights date back to the 1800s. Reports often describe brightly glowing basketball sized spheres floating above the ground, or sometimes high in the air. Colors are usually described as white, yellow, orange or red, but green and blue are sometimes reported. The balls are said to hover at about shoulder height, or to move laterally at low speeds, or sometimes to shoot around rapidly in any direction. They often appear in pairs or groups, according to reports, to divide into pairs or merge together, to disappear and reappear, and sometimes to move in seemingly regular patterns. Their sizes are typically said to resemble soccer balls or basketballs

The Mayan prophecies

According to an increasingly large number of people, the Mayan Prophecy states that the world as we know it will change on December 12, 2012. This is not a new phenomena; as landmark dates draw near, end of the world theories creep out of the woodwork with astonishing popularity.

However, this particular theory has been around for more than 5000 years. It began when the ancient Mayans plotted our position in the Milky Way and launched the Mayan calendar.

The Mayans believed that in the year AD 1999, mankind would have 13 years to recognize our own patterns of self destruction. Then, starting December 12, 2012, our entire lives would be tested and only those most in touch with their spiritual sides would survive (as some interpretations have it). Many people take this as a sign that a natural or manmade disaster will occur, tearing apart the civilized world and taking us back to hunter-gatherer days.

There are other interpretations too: from sun storms to the eruption of a super volcano; from a magnetic field reversal to a meteor impact. Some people even point to the Large Hadron Collider in Switzerland as the bringer of doom.

While the world may come to an abrupt end any time, any day, without warning - one thing is for sure: our modern society, like all civilizations before us, is geared to postulate over end-of-the-world mysteries with gusto.
