What Is the Beauty of String Theory?

Super symmetry suggests that every particle has its own super partner. Electrons would have electrons, top quaks would have stop quacks and atoms would have their superpartners. Mito says he already sees symmetry like this in a lot of places in our universe. We think that super symmetry could be the ultimate symmetery of the universe. What does it rotate? It rotates the entire universe into itself. This is what we consider beautiful sup symmetry. Then according to string theory could also lead to this grand unified theory - but it's still eraced to see which theories are right.
