Wavefunction collapse is a cornerstone of quantum mechanics, describing the transition of a quantum system from a superposition of states to a single, definite state upon measurement. This phenomenon raises profound questions: Is the collapse a physical process, or does it merely reflect our lack of knowledge? Does the observer play an active role in shaping reality, or is the act of measurement simply a passive interaction? Exploring this question delves into various interpretations of quantum mechanics, such as the Copenhagen interpretation, Many-Worlds theory, and objective collapse models, each offering a unique perspective on the nature of reality and the role of consciousness.
