A 3D explorer for three of the leading hypotheses about physics beyond the Standard Model. The SUSY view lays out every quark, lepton and boson beside its hypothetical superpartner and fades them in once the energy slider crosses the SUSY-breaking scale. The extra-dimensions view visualizes a compactified geometry and the Kaluza-Klein excitation tower that a higher-energy probe would resolve. The GUT view runs the three gauge couplings with one-loop renormalization-group equations and plots them on a log-energy chart, showing the classic near-miss for the plain Standard Model and the near-perfect meeting point once superpartners are added to the loops.
