For those who are somehow religious/spiritual and hold the Bible as truth, here's a rough explanation about why the world is not coming to an apocalypse like in Hollywood movies.
First, the book of Revelation never says that the Earth will be destroy by a cataclysmic event. Yes, there's a meteorite involved, but it never disintegrates a great mass of land -- or water -- and annihilates life through and explosion. It just falls and contaminates water; no gigantic Armageddon-style waves that inundates entire cities. The book is mainly metaphorical and when talks about destruction, it is about the end of this system of things -- or better put, the reign of the Dark Prince's age and the restoration of God's kingdom. Plus, when New Jerusalem comes down from Heaven, it will be placed on Earth; it'd be a shame to see such a beautiful city surrounded by a horrible Terminator-like landscape. And no, it won't happen in 2012 as the Mayan predicted.
Here are some passages you should read:
For this is what the LORD says—
he who created the heavens,
he is God;
he who fashioned and made the earth,
he founded it;
he did not create it to be empty,
but formed it to be inhabited—
he says:
“I am the LORD,
and there is no other [...]
Isaiah 45:18 NIV
He said to them: “It is not for you to know the times or dates the Father has set by his own authority.
Acts 1:7 NIV
In fact, He hates the ones who destroy the Earth:
“I am against you, you destroying mountain, you who destroy the whole earth,” declares the LORD. “I will stretch out my hand against you, roll you off the cliffs, and make you a burned-out mountain.
Jeremiah 51:25 NIV (similar to Revalation 11:18)
Still I think there's gotta be some kind of natural disaster as the next passage says -- I believe the author is being hyperbolic:
But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.
2 Peter 3:10 NIV
