Speculation that mentioned civilization will end in 2012 it is not true. Issues regarding the existence of a large star that will strike the Earth in the year 2012 has yet to be proved.
The researchers argue, there is currently no documentation in research that is able to identify types of threats that are seen as big as that. Those who argue that it is real and is capable of engaging incoming asteroids in the solar system to have absolutely no evidence to present.
When the idea of Nemesis first appeared, this idea was used to describe what the experts refer to as the periodicity of mass extinctions on Earth. In other words, after analyzing the intervals at which there are five symptoms of the onset of the great extinction event, these scientists think they have noticed a pattern. Such as quoted Softpedia, Thursday (10/8/2011).
But until today no one is able to show proof that Nemesis orbits in the Oort Cloud comets, some astronomical units (AU) from Sun. AU is the average distance between the Sun and the Earth, i.e. approximately 93 million miles.
Thinkers who support the theory that States that the object of Nemesis orbits very far from the Sun, and yet somehow quite large objects can be nudged the comet. An object believed to be responsible for the Comet which regularly sent to the solar system that is part of the cloud.
Bailer-Jones (astronomy in Heidelberg) using statistical tools known as call Bayesian Networks analysis to study the rate at which mass extinction event occurred during the last 250 million years, but they could not find the kind of patterns that could indicate the existence of the Nemesis.
Just like a conspiracy theory proposed planet Nibiru, Nemesis appears to be a figment of someone's imagination. If one of the two objects really exist, it's an astronomical impossibility, because both of these objects should have been detected since a long time.
"Of note, there is no evidence to Nemesis. Something that is left is an interesting question or lack of impact that often occurs during the last 250 million years, "knot Bailer-Jones.
