DID ANY ONE KNOW WHEN D WORLD IS ENDING?
As we all know from school lessons in geography, the thickness of the ozone layer that protects Earth's surface from solar radiation, is very small, and people stubbornly continue to do everything to be reduced even further. As a result, the appearance of ozone holes, which will eventually lead to the complete destruction of the ozone layer, then the radiation will simply kill all life.
The most common version of end of the world is falling to Earth asteroid. Scientists have put forward the theory that this is what killed the dinosaurs. Perhaps with time and the human remains will be decorating a Museum. Possible and the second option: our planet will face in outer space with another space body, resulting in smashed into a huge number of small fragments, which become satellites of other planets.+
Some scientists suggest that the world could end and if the Sun just goes out. Yes, this is possible. But there will be it explicitly not in 2012, and after about ten billion years.
