With all this nonsense circulating around the Large Hadron Collider it is (arguably) good to know if those (supposedly) crazy scientists at CERN managed to create a black hole that destroyed the world. Luckily, there is a website that can tell you if the world is destroyed yet.
http://hasthelargehadroncolliderdestroyedtheworldyet.com/ will tell you the definite answer on the question. In the source code, the author of the website has set up an actual script that finds out if the world is destroyed. In addition to this, he says that if the website is not updated in time, he will give you a refund.
