When is the world gonna really end?

When is the world going to really end? Scientists point to December 21, 2012. They say the sun will blast huge heat rays of some sort.Our magnetic field will just not be able to handle them, and give way, causing us to burn up, and or be vaporized. The Mayans calender stopped at 12/21/12, and people believe that that’s when the worlds gonna end. What I think, is that the mayans got extremely sick and tired of predicting the future, that they just stopped, or just stopped period. Or Another village wiped out the mayans in fear of what they may cause. Or, something bad happened, killing the mayans. Truely the Mayans were experts in math, but how the hell can you predict things that have not already happened with math?? So your saying that if I’m an expert in math, i’lll be able to predict the lottery numbers, or predict how much space there is in the universe. you see where i’m going with this.. So what do you think will happen? Will we find a way to boost the power of our earths magnetic field, or we will just die like a mouse being run over with a truck? What do you think, and all religions count in this question.
