That is why scientists have been hunting for violations of what is known as charge, parity and time reversal (CPT) symmetry - a central tenet of the Standard Model of particle physics, which states that the laws of physics remain unchanged even if a particle is replaced with its antiparticle, which has the opposite charge, and even if its spatial coordinates are inverted.
