Fermilab Discovery Science Resources: Nine Questions
1. Are there undiscovered principles of nature: new symmetries, new physical laws?
Our quest to discover the fundamental laws of nature has led to the revelation that the laws of physics and the particles they govern exist because of underlying symmetries of nature, some of them lost since the big bang. One such lost symmetry might be supersymmetry. Just as for every particle there exists an antiparticle, supersymmetry predicts that for every known particle there also exists a superpartner particle. Part of the strong theoretical appeal of supersymmetry, an essential part of string theory, is its possible connection to dark energy and the fact that it provides a natural candidate for dark matter, the neutralino.
