Series of newspaper headlines concerning the LHC creating an earth swallowing black hole, on top of picture of a black hole.

Supervisor: Dmitri Vladimir Fedorov

On September 10'th 2008, the Large Hadron Collider (LHC) was started for the first time. An accomplished scientist named Otto E. Rössler proposed the idea that a black hole might be created from the proton-proton collisions created at the LHC. He was afraid that such a black hole could then absorb surrounding matter, and thus grow, which in the end could lead to the black hole absorbing the entire planet.
In this presentation, I wish to tell the story of how Mr. Rössler’s idea, and publication of it, resulted in widespread fear, a huge number of articles on the subject, and even a lawsuit. Further, I wish to present some of the physics describing black holes, which includes basic general relativity. Then empirical evidence concerning the likelihood of such a black hole being created will be explored, and finally, a theoretical look at the consequences of the existence of a black hole, such as those that could be created at the LHC will be explored theoretically.
