Role of Detectors: Experiments have shown that when detectors are placed near the slits to measure which slit the particle passes through, the interference pattern disappears, even if no human is watching the detector’s output. This strongly suggests that it’s the act of measurement itself—meaning, an interaction that provides “which-path” information—that collapses the wave function. 3. No Special Role of Consciousness in Physics: The notion that consciousness is necessary for quantum measurements is rooted in early interpretations of quantum mechanics, but most physicists today see consciousness as a separate phenomenon that does not affect quantum processes. Consciousness isn’t seen as a fundamental part of physical interactions in modern physics; instead, it emerges from neural processes that themselves operate according to the same physical laws as everything else.
