Down the rabbit hole

We've come a long way since Copernicus dared to propose a sun centered solar system. We've moved past Newtonian mechanics. We've arrived at Einstein's theory of relativity. We've probed even further into the workings of quantum particles. And today we find ourselves trying to tie it altogether into one grand and unified theory. Unfortunately, whenever we think we've arrived there, or believe we've come close, we haven't. New data always comes along and shatters our previously "solid" ideas. The standard model today for particle physics is known to be incomplete. It fails to explain phenomena such as gravity and the abundance of matter versus anti-matter. For many years the strongest contending theory proposed to solve such issues was 'super-symmetry'. Super-symmetry is a theory that relates elementary particles of one spin to to other particles that differ by half a unit of spin and are called 'super-partners'. This symmetry, if proved, would have the potential to help eliminate many known problems and quandaries in modern day physics.
However, supersymmetry, which predicted the shape of an electron to be egg like, has benefited from little experimental proof, as recent experiments have measured the electron to be (as far as we can tell) spherical. http://www.bbc.co.uk/news/science-environment-13545453 Seeing as data has appeared which contradicts a prediction of supersymmetry, physicists may find themselves having to rethink the theory. It would seem we are back to the drawing board again. Our worldview and scientific understanding never seems to cease changing. Will it ever? Will we ever understand the universe completely and come to the end of mankind's scientific exploration? I doubt it. The designer, if any, sure made it a challenge.
