In the pure linear theory of an isolated system, all quantum states (including dead cat superposed with live cat) appear symmetrically. What breaks the symmetry? • There are explanations of why some states are more equal than o ...

Moreover it depends on some weighting of the different aspects of the states which one wants to distingui ...
