The Klerksdorp Spheres: These puzzling little spheres were found by miners in South Africa in Pyrophyllite-type, crystallized rock deposits. The origins of these metallic spheres are unknown and around 0.5 to 10 cm in diameter. Some have concentric grooves running along their equators and seem to have been made by intelligent design. The crazy part however, is that the Pyrophyllite deposits they were found in were dated to be around 2.8 billion years old! This beats out the current estimate of intelligent life by, oh, a few billion years!

The Baigong Pipes: In rural China, in an area considered uninhabitable by humans, there are three triangular openings at the top of a mountain. The strange thing about these opening is that they are filled with an iron pipe system of unknown origins. some pipes go into a nearby salt water lake, while others go deep into the mountain. More can be found inside of the lake and along the shore lines. Some are as wide as 40 cm in diameter and seem to be placed in a purposeful pattern. What's strange about them is that tests seem to place the date of these rusted iron pipes to nomadic times, before we discovered farming let alone advanced drilling and metal work. Oddly enough, the pipes are clean of debris, indicating that it was possibly used for some purpose and not just stuffed in the mountain. Locals speculate it to be an ancient astronomy lab, or a landing base for alien space ships, but who knows.

A Blank Spot in the Universe: Astronomers have found the biggest blank spot in the universe, and it has everyone scratching their heads. This mysterious blank space in the cosmos is void of any stars, galaxies--It's just a big space of nothing. Different from a black hole, which can be observed through nearby stars that are pulled into its gravitational orbit, this hole just seems to be empty. The crazy thing about this big spot of nothing though is that it is estimated to be 1 BILLION light years across, making that nearly 6 billion light years of complete emptiness. That's a lot of nothing! It was discovered by accident when astronomers at the University of Minnesota were taking surveys of the night sky. By using radio photography to scan big expanses of the universe, the area was revealed to be a complete cold spot, void of any matter.

The Placebo Effect: You may have heard of it before, but the placebo effect is a mystery to scientists. The placebo effect is a phenomenon in which patients are given a fake therapy or drug and are told it will help them in some way or form. Studies have shown that placebos actually fight sickness--in some cases just as well if not better than the actual medicine they are disguised as being. These studies seem to suggest that the power our mind has to heal ourselves is greater than we have ever thought. Scientists are still baffled as to how this happens.

The Mysterious Moving Stones: In some deserts across the world there are stones that seem to move along the surface of the ground. They leave trails behind, sometimes having taken right angle turns during their journeys. One might first write them off as being pushed by the wind, but the speeds at which the wind has to blow to move these rocks is highly unlikely. The linear pattern also suggests that the rocks slide across the floor rather than being pushed around by any wind. It is still unknown why these stones would be able to slide across the desert in such a fashion.
