disprove a theory

Meaning

To 'disprove a theory' means to show or prove that a scientific idea, hypothesis, or belief is false or incorrect using evidence, logic, or experimentation. This is a fundamental concept in the scientific method, where theories are tested and updated. The tone is formal and objective.
