Machan, If you are Buddhist, no need to worry about worlds end in 2012. because according to my knowledge Buddhism should last 5000 years. So our world should last at least another 2500 years or so...
i also knw that but i dont say the world completely destroy but some major thing might happen...
once i watched a discovery channel programme about an island in pasific ocean , under that island there is a volcano active but still no harm for anybody , but now scientists have discovered seawater leaking in to the core of the volcano n the amount of sea water coming inside has increased a bit , so they say if anyhow a huge amount of water comes in to that core suddenly it will give a blast which will be powerful as a nuclear bomb n will creat a tsunami wave atleast 60meters high .. it will first affect califonia n the us sea coast , they say definetly one day it will happen but they can't predict a date ... so the tiddle wave wave will travel all around the world , it is that much powerful , so.....
i dnt say this will happen in 2012 but it suddenly came to mind when this topic came out .. i watched that programme about 5 years ago ......
