SUSY — every Standard Model quark, lepton and boson (left lattice) gets a heavier superpartner (right lattice, glowing, tilde-labeled) differing by half a unit of spin. Slide the energy scale past the SUSY-breaking threshold (~1 TeV) and the superpartners fade in — below it they are too heavy to have been produced yet.
Extra dimensions — a compactified geometry (torus) sits at the origin. Its apparent size and the number of visible Kaluza-Klein excitation rings orbiting it scale with the probe energy: higher energy resolves finer structure, exposing more of the curled-up dimension.
GUT — the three gauge couplings (α₁ hypercharge, α₂ weak, α₃ strong) are run with one-loop renormalization-group equations, plotted as 1/α vs log₁₀(Q). The dashed lines are the plain Standard Model (they miss each other); the solid lines add SUSY partners to the loops and very nearly meet near 2×10¹⁶ GeV — the textbook argument for grand unification.
1/α_i(Q) = 1/α_i(M_Z) − (b_i / 2π)·ln(Q / M_Z)
