This one is more or less for Tsaphah. It shows why I said that the CERN runs the Big Bang history backwards. The more you get high energies, and above all, particles having higher and higher energies when they collide (through speed), the earlier you get into the Big Bang history and what is thought to have taken place back then. Source : How an accelerator works Electric fields and radiofrequency cavities accelerate particles inside accelerators, while powerful magnets focus or steer the particle beams. (...) Their job is to speed up and increase the energy of a beam of particles by generating electric fields that accelerate the particles, and magnetic fields that steer and focus them. (...) Collisions at accelerators can occur either against a fixed target, or between two beams of particles. Particle detectors are placed around the collision point to record and reveal the particles that emerge from the collisions.
