Theory of everything differ both from gravity and from electromagnetism. A further hurdle was the acceptance that in a TOE, quantum mechanics had to be incorporated from the start, rather than emerging as a consequence of a deterministic unified theory, as Einstein had hoped. Gravity and electromagnetism could always peacefully coexist as entries in a list of classical forces, but for many years it seemed that gravity could not even be incorporated into the quantum framework, let alone unified with the other fundamental forces. For this reason, work on unification, for much of the twentieth century, focused on understanding the three "quantum" forces:
Unified Theory (band) they relocated to Los Angeles and began recording their debut album. The album was recorded at Stank Face Laboratories and Lucky Dog Studios in Seattle, and was produced by both Thorn and Smith, and mixed by Andy Wallace. Jon Bolton and Matthew Steer contributed additional drums to the recording, while string arrangements were handled by Dave Dysart. In June, Unified Theory shot a music video for their first single "California" with director Bobby G, before touring the US in July. The band's debut album entitled "Unified Theory" was released on August 15, 2000, through 3.33 Music Group in North America
