3.4.5.12 Objective Collapse Theories
Objective collapse theories differ from the Copenhagen interpretation in regarding both the wave-function and the process of collapse as ontologically objective. In objective theories, collapse occurs randomly, in “spontaneous localization”, or when some physical threshold is reached, with observers having no special role. Thus, they are realistic, indeterministic, no-hidden-variables theories. The mechanism of collapse is not specified by standard Quantum Mechanics, which needs to be extended if this approach is correct, meaning that Objective Collapse is more of a theory than an interpretation.
