In hypothetical experiments with closed boxes, particle decay triggers processes that kill cats {Schrödinger's cat} {Schrödinger cat}. If decay probability is one-half, is cat half-alive and half-dead inside box until observed? Is cat dead when particle decays, observed or not? In which state is cat after event and before observation? Less and less classical objects and events can replace cats, until replacements are quantum events and particle decay triggers a quantum state, so when does quantum-event wavefunction collapse?
