Causality (physics)

Causality in physics refers to the relationship between causes and effects, which is fundamental to understanding the natural world. It is a principle that establishes a cause-and-effect relationship where an event (the cause) leads to the occurrence of another event (the effect). This concept is crucial in various branches of physics, including classical mechanics, quantum mechanics, and relativity. 1. **Classical Mechanics**: In classical physics, causality is often straightforward.
