theory

System of ideas

A theory is an idea that is proposed to explain something.

A theory can be very simple (My theory is that she decided to leave him a long time ago) or extremely complex—like the theory of quantum mechanics.

In science, researchers propose a theory and then devise experiments that will prove the theory is correct (that it explains the phenomenon), incorrect (fails to explain what happens experimentally), or occasionally incomplete (explains some aspects satisfactorily, but not others).
