Energy burstsImagine the energy of a speeding train, packed into a narrow beam of particles. When two of these beams collide inside the LHC, they'll produce tiny bursts of extremely high energy.
The same amount of energy, on a much bigger scale, existed less than a billionth of a second after the Big Bang. This will be the first time scientists have created such high-energy collisions.
