The European Organization for Nuclear Research (CERN) is one of the largest centers for basic research in physics. Its Large Hadron Collider (LHC) is used to research the fundamental laws of the universe. The LHC is an underground, 27-kilometer-long ring in which conditions are reproduced as they were at the beginning of the Big Bang. For this purpose, protons are shot at each other at almost the speed of light. The collision can also create tiny black holes. Conspiracy theorists fear that these little black holes could break out of the laboratory and cause the end of the world. Others believe that the researchers could accidentally or deliber- ately open the portal to a parallel dimension, through which evil forces would then flow to Earth to destroy or subjugate humanity. It goes without saying that these fantasies are not based on facts.
