Should the world suddenly end in the next few days, you won't even notice it:

Our planet is not at risk from the world's most powerful particle physics experiment, a report has concluded.

The document addresses fears that the Large Hadron Collider is so energetic, it could have unforeseen consequences.

Critics are worried that mini-black holes made at the soon-to-open facility on the French-Swiss border might threaten the Earth's very existence.

But the report, issued the European Organization for Nuclear Research, says there is "no conceivable danger".

Seriously, if something were to happen and one of those mini-black holes became large and/or energetic enough to do damage, there wouldn't be much time to worry about anything.
