John Baez on CPT symmetry, antimatter, and the arrow of time
Conversation with John Baez. Talks about charge conjugation and antimatter (electron–positron annihilation into light), parity / mirror-image worlds and chirality (dextrose vs levulose, \~19:30), and time reversal leading into why the future looks so different from the past and the Big Bang (\~20:30). Later he reflects on his own quantum-gravity work and whether an AI cracking it would bother him (\~33:00).
