Measurement Problem
A fundamental problem in quantum mechanics concerning the mechanism by which measurement causes wave function collapse; the standard theory does not explain its physical mechanism.
Timeline (last 90 days)
Decoherence theory explains why macroscopic superpositions are not observable, but it does not solve the problem of why a single measurement yields only one result.
The many-worlds interpretation sidesteps the measurement problem by abolishing the collapse postulate, holding that measurement is simply a natural consequence of quantum entanglement.
