This means that if you are working on time-scales where Fermi's rule is applicable, measuring whether that particle has decayed or not will do nothing to the decay rate… Quantum zeno effect happens when you muck up the states in intermediate times, before Fermi's golden rule has a chance to become valid.' physics.stackexchange.com/questions/33232/… | |

| Feb 7, 2018 at 16:20 | comment | added | Steve | The problem is, what are these "other universes"? Presumably they cannot be detected, since the moment they come into existence they become inaccessible. Far from being unobjectionable, it's one of the most fanciful and outlandish hypotheses! | |
