I have a brilliant idea that just might save the world from impending doom.
On the one hand you have the death-planet Nibiru, hurtling towards Earth and on target to collide with it in 2012. On the other, the Large Hadron Collider is once again operational and will be producing a planet-gobbling black hole any day now.
Do I need to spell it out? Use the black hole to intercept Nibiru! Use Nibiru to plug up the black hole! This kills two disasters with one stone, literally. Two great apocalypses that go great together. Really I don't understand why I'm the first person to suggest this.
