Particle physicists working at CERN's Large Hadron Collider have found four new tetraquarks that might test the laws of nature.
These particles contain a pair of charm quarks and two other quarks.
Their discovery, just like any other good one, has raised new questions about the laws of the quantum universe.
So far, the LHC has found 59 new particles. It also discovered the Higgs Boson in 2012. Its aim is to study physics beyond the standard model.
