Are we missing a dimension of time?

A Univ. of Southern Calif. scientist has put forward the bizarre suggestion that there are two dimensions of time, not the one that we are all familiar with, and even proposed a way to test his heretical idea next year. If it is confirmed, it could point the way to a "theory of everything" that unites all the physical laws of the universe into one.

"There isn't just one dimension of time," Itzhak Bars of the University of Southern California in Los Angeles tells New Scientist. "There are two. One whole dimension of time and another of space have until now gone entirely unnoticed by us."

Bars claims his theory of "two time physics", which he has developed over more than a decade, can help solve problems with current theories of the cosmos and, crucially, has true predictive power that can be tested in a forthcoming particle physics experiment.
