How the world could end today Dark comet Fri-21-Dec-12 09:32 Share this By Jay-Jay FeeneyIf the world really DOES end today, Scientists say the most likely scenario would be a DARK COMET hitting Earth. Dark comets aren't covered in snow and ice so they're harder to spot in space. It would kill the people in the area of impact, and shoot so much dust into the atmosphere that the rest of us would die slowly and painfully too because it would block the sun, and cause all the crops worldwide to fail. So we'd all die slowly and painfully from a global famine. The second-most likely scenario would be an underground volcano erupting. That would have the same effect of shooting dust into the atmosphere.
