Physical laws possess a fundamental notion of causality
Whether physical laws possess a fundamental notion of causality remains contested, as traditional frameworks rely heavily on a causal arrow of time and energy transfer, while advanced interpretations in quantum mechanics explore retrocausality and the potential abandonment of microscopic causality.
The retrieved papers show a deep division in physics regarding causality. Papers [6] and standard foundational views (noted in [0] and [1]) treat causality as a core driver of physical processes, time, and entropy. However, papers [0] and [1] also detail how quantum mechanics, Bell's theorem, and relativity create severe tensions with standard microscopic causality, leading some theorists to explore retrocausal and non-causal frameworks. This active debate places the claim in the CONTESTED category.
