No, quantum physics does not disprove causality. Causality, the principle that events have causes and that causes precede their effects, remains a fundamental concept in physics and our understanding of the natural world.
Quantum physics, which describes the behavior of particles and physical phenomena at the smallest scales, introduces probabilistic behavior and uncertainty into the fundamental laws of nature. It introduces the concept of indeterminism, where the outcome of certain events or measurements cannot be predicted with certainty but rather described in terms of probabilities.
However, within the framework of quantum mechanics, causality is still preserved. The evolution of quantum systems is governed by mathematical equations, such as the Schrödinger equation or the equations of quantum field theory, which are deterministic and causal. These equations describe the time evolution of the quantum state and how it is influenced by various interactions and external factors.
While the specific outcome of a quantum event may be uncertain until it is measured, the cause-effect relationship between the initial conditions and the subsequent evolution of the system remains intact. The probabilities associated with different outcomes are determined by the underlying physical laws and the properties of the quantum state.
It is worth noting that some interpretations of quantum mechanics, such as the Copenhagen interpretation or the Many-Worlds interpretation, may introduce philosophical debates or discussions about the nature of reality, measurement, and determinism. However, these interpretations do not invalidate the concept of causality as a fundamental principle in physics. Causality remains a key aspect of our understanding of the natural world, even within the framework of quantum physics.
