Unified field theory classical field theory and, two years later, that of Theodor Kaluza, who extended General Relativity to five dimensions. Continuing in this latter direction, Oscar Klein proposed in 1926 that the fourth spatial dimension be curled up into a small, unobserved circle. In Kaluza–Klein theory, the gravitational curvature of the extra spatial direction behaves as an additional force similar to electromagnetism. These and other models of electromagnetism and gravity were pursued by Albert Einstein in his attempts at a classical unified field theory. By 1930 Einstein had already considered the Einstein–Maxwell–Dirac System [Dongen]. This system is (heuristically) the super-classical [Varadarajan] limit
Unified Theory (band) to tour in support of their album. However, the tour was soon cancelled after Blind Melon parted ways with Warren. The band were to perform a number of shows with Thorn and Smith's former band mate Shinn, though a lack of preparation time resulted in the band cancelling the tour. Unified Theory released their second album "Cinematic" on iTunes in December 2006. The band did not reunite to perform any shows to promote the album. Unified Theory reunited for one show on August 4, 2010 at the King King in Hollywood. Chris Shinn's other band Everything is Energy opened the
