To claim that an idea carries potential to become a theory, three key aspects must be satisfied. Firstly, an idea must possess an observable form, either directly or indirectly. Secondly, our claim must be measureable and lastly it should be falsifiable, meaning, claims must be tested with the help of observable measures. Let’s say there is a claim that “Man is immortal”. This idea cannot become a theory, though, idea is observable and measurable, but it cannot be falsified, Thus, ideas which satisfy the criteria of being observable, measureable, testable and subject to change alone considered an input for construction of a theory.
