Undergrad Observer superposition in MWI?

Click For Summary
In the Many-Worlds Interpretation (MWI) of quantum mechanics, measurements do not lead to the observer being in a superposition of different worldlines, as this concept is based on a false premise. Instead, there is only one universe where the observer and the observed system are entangled, resulting in a combined state that is well-defined. The discussion clarifies that MWI does not involve a collapse of the wave function; all outcomes exist within a single quantum system undergoing unitary evolution. The entanglement process does not imply that the measurement device or the observer experiences multiple outcomes simultaneously, but rather that they are part of a unified entangled state. Ultimately, the conversation emphasizes the importance of precise terminology in discussing these complex quantum concepts.
