This is probably the most elaborate analysis in explaining 2012 phenomenon, which marks the end of time, not the end of the world. (with assumptions of course)
The End of Time
But after the read of the article, why does time follow earth's relative revolution around the Sun. If so, time is a human-created entity. But arguably since Space is not a human-created entity, it is highly possible space created time, since in many sciences both space and time are highly related. If space was created by something, why does it not occur to matter, but dark matter, and how dark matter becomes matter? ??? ???
