When three tests must all theories pass to be considered a proven theory?

For a theory to be considered proven, it typically must pass three key tests: empirical validation, consistency, and predictive power. Empirical validation requires the theory to be supported by observable and repeatable evidence. Consistency means the theory should align with existing knowledge and not contradict established laws of science. Lastly, predictive power indicates that the theory can accurately forecast future events or outcomes based on its principles.
