Dec 21st, 2012...End of the world?

It all started with the story of a supposed planet approaching earth 'Niribu'. But NASA denies this saying that there are no factual claims to this. The strangest part is that most calendars are signaling towards this end! However NASA gives a sigh of relief by calling it 'Just Another Day'. NASA's website (http://www.nasa.gov/topics/earth/features/2012.html) clears the air...

NASA says, "There are no planetary alignments in the next few decades and even if these alignments were to occur, their effects on the Earth would be negligible." Also, as per NASA a magnetic reversal is unlikely to happen in the next few millennium and wouldn't cause any harm to life on Earth.
On the flip side, the most talked about Mayan calendar ends long-count period but then-just as your calendar begins again on January 1-another long-count period begins for the Mayan calendar.

Certain astrologers believe that the negativity will die and the world will evolve for better and for which humans will have to pay a price. This price can be in the form of natural calamity, financial problems, wars, etc.

Deepak Patel, CEO, Aditya Birla Minacs says, "I do not believe that 2012 will be end of the world. If my world is going to end, it can end today, it can end tomorrow. At the end of the day, you want to spent your life doing things you enjoy"

HINDUISIM
According to Hindu scriptures, there is a connection between Kali Yuga and 2012. Some astrologers are predicting that Kali Yuga will end in 2012 and Satya Yuga will begin from December 21, 2012. Astrologers believe that the world will move into a golden age, marking the beginning of Satya Yuga.

CHRISTANITY
It describes an end of the age and a new heaven and a new earth but Ecclesiastes 1:4 says, "Generations come and generations go, but the earth remains forever." Revelation 1:2 tells us that the Holy City, Jerusalem, will descend out of heaven and come down to the earth.
ISLAM
Knowledge of the Hour is with Allah alone. (Holy Qur'an 31:34). The exact time of the Doomsday is given neither in Qur'an nor in Hadith.
