In our comfortable, three-dimensional experience, black holes skulk far away in the heart of the galaxy. They are the demise of massive stars and can only be created at great energy scales – much higher than anything we can achieve in our earthly laboratories.
In fact, for a particle to be both energetic and dense enough to form a black hole, it must be many orders of magnitude beyond the energy achieved by the Large Hadron Collider at CERN, where particles are slammed together at near light speed.
But physicists at the LHC have been scouring the data for miniature versions of black holes since the particle accelerator began running in 2008.
