Explain Null experiment

Null experiment: The experiment which, after being performed, yields no outcome. The null experiments are just as significant as non-null experiments; when current theory predicts an observable result (or predicts there must be no observable result), and experimentation (in the requisite accuracy) does not yield said result, then the null experiment has told us rather about our theory.
