Explain why the results of an experiment are never really final results. The experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. It can also call for a new theory, either by showing that an accepted theory is incorrect or by exhibiting a new phenomenon that is in need of explanation.

Because science and nature evolve and experiments are fallible.

Explanation:

Scientific experiments are set up to try to explain natural phenomena. However, nature is a complex and very inefficient system that may not present clear data so that experiments can develop a result that explains an absolute truth. In addition, the experiments are fallible, which means that they are susceptible to errors and may present inconsistent results. For this reason, it is important that science does not stop and always tests experiments already done before, as well as test theories to demystify them and present results that are always closer to the real.
