Hundreds of physicists from Europe and beyond have met in Granada, Spain to develop a plan for a next-generation collider that will eventually supersede the Large Hadron Collider (LHC) at CERN. One CERN proposal for a next-generation collider is the Future Circular Collider, which would have a 100 km circumference and collide protons at energies up to 100 TeV. In contrast, the LHC has a 27 km circumference and a collision energy of 13 TeV. Another CERN proposal is the Compact Linear Collider, which would smash together matter and antimatter. Could this bring about something prophetic?
