Parity violation

Parity violation refers to the phenomenon where certain physical processes behave differently when viewed in a mirror, violating the expectation that nature should appear the same in both left-handed and right-handed configurations. This surprising discovery emerged from experiments in particle physics, particularly involving weak interactions, such as certain types of radioactive decay. In essence, while most physical laws remain unchanged when mirrored, parity violation highlights that some fundamental interactions do not obey this symmetry, challenging our intuitive understanding of the universe and leading to deeper explorations in theoretical physics.
