An alternative way to view measurement is that you're just entangling yourself with the quantum system, and are as much in superposition as the system itself.

- jonahbenton 6y agoThanks, yeah. With this view I run into trouble understanding what constitutes "entry into" and "exit from" superposition.
- ahelwer 6y agoPresumably, nothing was in superposition when the universe began. Everything after that evolved in time according to the Schrodinger equation, with everything becoming more superposed (i.e. their exact properties less certain) and entangled with everything else to at least some degree. Things can be more or less entangled with other things, and when you measure something you become very strongly entangled with it.
