Every experiment may be said to exist only in order to give the facts a chance of disproving the null hypothesis. Yet in many experiments it is well known (or at least well accepted) that there are differences among the treatments. The point of the experiment is to estimate the magnitude of these differences and provide estimates of the standard errors associated with the estimates of these differences.
