Causality in quantum mechanics
Causality in quantum mechanics refers to the principle that effects follow causes, maintaining a consistent order of events. However, at the quantum level, particles can behave unpredictably, and measurements can influence outcomes in ways that seem to challenge classical cause-and-effect relationships. Despite this, causality is preserved in the sense that information or signals cannot travel faster than light, preventing paradoxes. Quantum entanglement shows correlated properties between particles regardless of distance, but it doesn't allow for faster communication, thus maintaining causality. Overall, quantum causality accommodates probabilistic events while respecting the fundamental limitation that cause-and-effect relationships stay consistent within the universe's physical laws.
