What will particle physicists be studying after the 27 kilometer-long Large Hadron Collider at CERN has given up all the secrets it knows about the Universe?
Designs are being made for the particle accelerators and detectors of the future, building upon knowledge gained by the LHC by smashing together particles that we can just barely control today. CLIC is one of these, a linear accelerator that would smash together electrons and their anti-matter twin, positrons.
