Ok, in 2012, people say the worlds gonna end. It wont, dont worry. But, if the planets do align, there will be major earthquakes. It's a proven fact, that after an eclipse, there is earthquakes. So, thats just the sun and moon, imagine all the planet's gravity pulling on the equator. Yes, that means huge earthquakes. But, that might not happen, so DON'T FREAK OUT!
