>The point of an experiment is to find out what you don't already know. Not necessarily true in physics. Many experiments are done to confirm a theory or to measure a known value more precisely. Both of these intentions are highly valuable. We've done many experiments to confirm general relativity for example. But obviously, people doing the experiments would like to see a different result than the prediction and win a Nobel Prize.
