The ancient Mayans and their calendar does not claim an apocalypse will take place on 21/12/2012, just a change in era, a 'shift in human consciousness' and ascension of capable humans into the next evolutionary stage, supposedly granting those capable of evolving with the ability to live within the 5th dimension, being 'whole' and interconnected with everything in the universe. It's scary how scientific evidence reinforces this apparent evolutionary jump, on the 21/12/2012 our solar system will pass through a region of space which contains highly charged torsion energy. Exposure to highly charged torsion energy has been proven to result in an evolutionary jump, and is responsible for the sudden evolutionary changes within species. It is the empty 95% of your DNA strand. At a lower level, It is emitted from the supermassive black hole in the centre of the milky way. Scientists speculate it is responsible for DNA coding.
The 'apocalypse' is a misconception due to inadequate translation of the Mayan scriptures and fictional representation of the Mayan calendar conveyed through films and in the media.
