The Large Hadron Collider is turning on at its highest power level ever to search for dark matter

The Large Hadron Collider was turned back on today (July 5) and is expected to slam together particles at never-before-seen energy levels.

That Large Hadron Collider (LHC) is the largest and most powerful particle accelerator in the world. Is located CERN Located near Geneva, Switzerland, the nearly 17-mile (27-kilometer) loop went live today after being offline for four years for upgrades. After those repairs are complete, scientists plan to use the gargantuan accelerator to smash together protons at record-breaking energies of up to 13.6 trillion electron volts (TeV) — an energy level that should increase the chances of the accelerator producing particles that science has determined have not yet been observed.
