Local Realism

Local realism is a concept in physics asserting that objects have definite properties independently of measurement (realism), and that no influence can travel faster than light (locality). It implies that distant events cannot instantly affect each other, preserving a cause-and-effect relationship consistent with relativity. This idea underpins classical physics, where objects have specific attributes, and interactions occur through signals traveling at or below light speed. Experiments testing local realism, like Bell tests, show that the universe doesn't always obey these principles, revealing inherently quantum behaviors that challenge classical assumptions.
