Itzhak Bars is a theoretical physicist at the University of Southern California in Los Angeles. In 2007, Bars presented the theory that time does not have only one dimension (past/future), but has two separate dimensions instead.

Humans normally perceive physical reality as four dimensional, i.e. three-dimensional space (up/down, back/forth and side-to-side), and one-dimensional time (past/future). Bars' theory proposes a six-dimensional universe, composed of four-dimensional complex space and two-dimensional time.

Physicist Joe Polchinski, at the Kavli Institute for Theoretical Physics at UC Santa Barbara, has said “Itzhak Bars has a long history of finding new mathematical symmetries that might be useful in physics... This two-time idea seems to have some interesting mathematical properties.” Quoted from article below.

Itzhak Bars's theory was a featured cover story in New Scientist magazine on October 13, 2007, and was again a featured cover story in Filosofia magazine on October 26, 2011.

He was a visiting scholar at the Institute for Advanced Study in 1979 and again in 1990.[1]
