👉 Antimeson is a concept in physics that describes an event or phenomenon where a system exhibits both a positive and negative energy state simultaneously. This contrasts with the classical notion of energy being either conserved (in which case it cannot change) or released (in which case it can be changed). The term "antimeson" was introduced by physicist Pauli in 1930s to describe such phenomena, but its precise definition and significance have remained open to debate among physicists.
