Detailed explanation-1: -Like all knowledge in science, no theory can ever be completely certain, since it is possible that future experiments might conflict with the theory’s predictions.
Detailed explanation-2: -Scientific theories are testable. New evidence should be compatible with a theory. If it isn’t, the theory is refined or rejected. The longer the central elements of a theory hold-the more observations it predicts, the more tests it passes, the more facts it explains-the stronger the theory.
Detailed explanation-3: -A scientific theory is not the end result of the scientific method; theories can be proven or rejected, just like hypotheses. And theories are continually improved or modified as more information is gathered, so that the accuracy of the prediction becomes greater over time.
