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
Classical unified field theories other hand, eventually abandoned classical unified theories. Current mainstream research on unified field theories focuses on the problem of creating a quantum theory of gravity and unifying with the other fundamental theories in physics, all of which are quantum field theories. (Some programs, such as string theory, attempt to solve both of these problems at once.) Of the four known fundamental forces, gravity remains the one force for which unification with the others proves problematic. Although new "classical" unified field theories continue to be proposed from time to time, often involving non-traditional elements such as spinors, none has been generally
