I don't want to seem to 'out there', but supposedly there is a Planet X that has a very long elliptical orbit (something like thousands of years for one cycle). Alot of people are saying that it is coming back inside the solar system. It is said to be a very faint object (but supposed to be large body) as it is thought to be a 'brown dwarf', so it would be more in the infrared spectrum of light.
Most of the ancient civilizations show a 10th planet/body in a 'solar system' drawings, such as the ancient Egyptians. The Mayans as you may know have there calender end on Dec 21/2012 which may or may not be the 'turn around' for the Planet X/celestial body? Nostradamus (philosopher), said ~ 500 years ago that the world would end on 2012. There is much more evidence suggesting 'something' is going to happen fairly soon; and alot are saying it's going to wreak havok on earth's weather patterns and bring on near extinction level events. There are alot of things that are totally undeniable, such that literally every civilization has written/cave drawings/or tails of "the great flood"; after all, even the bible speaks of the 'great flood', and 'noahs ark'... although probably drastically altered to fit the Christian 'tall tail'.
I better stop, or I will start babbling here. Sorry to spam your thread Takedown.
