I'd like to see an instance where experiments can end in mwi because it seems it never ends... example.. if the radioactive source emits alpha, it triggers an explosion and Schrodinger is dead. If it didn't he is alive (we often use Schrodinger's Cat example with the consequence we never think what happens next because we think alive is the final state). so consider Schrodinger himself. When he entangled himself with the radioactive source, there are two terms in the superposition which is "Schrodinger dead when source emits" and "Schrodinger alive when source doesn't emit". When the experiment happens. In one term, he is alive, in one term he is dead.. but since the wave function never disappear and the unitary evolution goes on and on with more entanglements.. then the experiments never ends because in the Schrodinger dead branch, the police would be entangled with them (Schrodinger and the source) and in the Schrodinger alive branch, her lover would be entangled with them also (Schrodinger and the source). So is it correct that experiments never end in mwi? If you disagree. Please give example of one where experiment can end in mwi. Thank you.
