Everett's MWI is based on QM which does assume a background
time and the state of the multiverse evolves in Hilbert
space. This evolution entails the evolution of the state of
different observers which are simultaneous.
Is an observer (or better many observers observing
simultaneously) is still necessary also by Everett's MWI? What
equation then describes an observer?
No. "Observer" is just shorthand for an interacting system that
"collapses" the wave function, i.e. couples the thing observed
into the quasi-classical environment. The observation is the
mathematical step of tracing over the environmental degrees of
freedom. So, within physics, there's an equation describing
Will the wave function collapse if we solve just the Schrödiner
Does this concern both, normal and MWI? If yes, then what MWI actually
