By referring to Maya Calender where till this day, 21 December 2012, after that, the calender won't able to count or continue already.

on this day, our galaxy and the solar system will arrange into a line, where this only happen each 26000years.
There is some scientific theory said that this phenomena will cause the magnetic field of the earth will change dramatically. where there might happen a lots nature disaster that may cause the end of the days.

There is some theory or belief said that this day is the end of the world, there is some of the belief said that this day is the change of our world where all of us might have a dramatically change where our spiritual power become more stronger, and the realistic world seem to be combine with our spiritual world.

From the some source of bible, 144000 people will be safe or survive at the end of the day, because it said that only 144000 people allow to go to new heaven.
if this day, 21 December 2012 is the end of the day, did it mean just 144000 will just survive?

There is also some of them doesn't believe on these thing, but there is something we need to worried. That is our fuel. Where from the research of some scientist about our main source of energy, petroleum might collapse in a near future, there is some statistic said that this might not more then 2020. so what is the replacement for petroleum? so far, we still dont have any replacement, if till that time also have no solution for this,how we gonna survive?

It's a end of the world? Or a good change to our world?
All these is goes either positive or negative.
