how long will this world exist.

No body can predict. There was a lot of predictions before, but nothing happend. So forget this and concentrate on our present life, rest leave it to the destiny.

Ask god !

hi,no body don't know exactly...for formation of this existing earth,atmosphere,it took millions of years....[say BIG BANG theory..or some EVELUTION theories..]..like that what happens we don't know...but it is in our hands to some extent...if we spoil OZONE LAYER....increase GLOBAL WARMING...the collapse of world will come near future..

i think the world will exist only another 10-15 years because the natural is not at all supporting us so soon the world will disappear only cockroaches will survive.. in this world

Only God knows........ After this life?? depend on your believe and religion

well no data available... but i hope it exist till m alive ..
