The Scientific Method has turned out to be the most powerful and widely used method of inquiry humans have ever discovered for un­der­stand­ing how our bodies, our world and our uni­verse work—not the way we might want things to work, not the way we believe things should work, but the way things actually seem to work. It’s a way of discovering which hypothe­ses among many possi­ble explana­tions are wrong, thus hom­ing in on the right ones. Correct expla­na­tions open doors to ever deeper and more profound discoveries; wrong explana­tions lead to blind alleys.
