>The experiment established that conservation of parity was violated (P-violation) by the weak interaction, providing a way to operationally define left and right. This result was not expected by the physics community, which had previously regarded parity as a symmetry applying to all forces of nature. Tsung-Dao Lee and Chen-Ning Yang, the theoretical physicists who originated the idea of parity nonconservation and proposed the experiment, received the 1957 Nobel Prize in Physics for this result. While not awarded the Nobel Prize, Chien-Shiung Wu's role in the discovery was mentioned in the Nobel Prize acceptance speech of Yang and Lee,[2] but she was not honored until 1978, when she was awarded the first Wolf Prize.
Why should I believe this?

K-mesons clearly display a particle-antiparticle asymmetry. K_long and K_short, despite being perfect antiparticles, get their unusual names from having completely different lifetimes so you can see how different they behave, if you trust the data (which has been verified by many different collaborations in several different countries). This sort of particle-antiparticle mismatch is exactly synonymous with CP violation.
and here CP refers to charge-parity symmetry. CP symmetry is a symmetry that only gets restored by incorporating it into CPT symmetry, which is obstensibly an axiomatic symmetry of the axioms of quantum field theory. I only add this second paragraph so that the party ban doesn’t get on my case about cheese pizza or the like.
since I’m waiting for this 10-minute counter to conclude ai would just like to add that it makes me very unhappy that using particle physics acronyms like CP for “charge-parity” exposes users to being investigated by the FBI. Trump and Vance should ask Elon how to improve their cheese pizza algorithms so that poor particle physicists don’t get erroneously vacuumed up by the blob’s domestic spying glowies

I don't see anything here that would look out of place if I were conducting the experiment on the other side of a mirror (like I am do)
