Unified Theory (band) Thorn and Shinn then regrouped with Smith and began recording material. It was during recording that Smith invited friend, and former Pearl Jam drummer, Dave Krusen to record with them, with Krusen eventually joining the lineup permanently, forming Luma in mid-1998. The following year, they released a four-song self-titled EP through their website, and toured the Pacific Northwest from July 29–August 18, the same year. By the end of the year, Luma changed their name to Unified Theory, named after Albert Einstein's final hypothesis unified field theory. By 2000, Unified Theory signed with Universal Records subsidiary 3.33 Music Group while
Unified field theory and Howard Georgi proposed unifying the strong and electroweak interactions into the Georgi–Glashow model, the first Grand Unified Theory, which would have observable effects for energies much above 100 GeV. Since then there have been several proposals for Grand Unified Theories, e.g. the Pati–Salam model, although none is currently universally accepted. A major problem for experimental tests of such theories is the energy scale involved, which is well beyond the reach of current accelerators. Grand Unified Theories make predictions for the relative strengths of the strong, weak, and electromagnetic forces, and in 1991 LEP determined that supersymmetric theories have the
