It’s another ‘gaseous Vulcan’.
M-theory isn’t even well-defined, being instead a vague collection of proposed patches to string theory that still hasn’t produced a testable prediction (or, maybe has—in which case it’s been proved wrong since we don’t observe the ‘dilaton’), so now Bars proposes to patch M-theory (whatever that is) with a second temporal dimension.
More cynically, M-theory is a way for string theorists to keep sopping up all the grant money, even though their theory has failed for 40 years to produced any actual progress, rather than allowing funding to be diverted to any of the radically different approaches like Connes’ recovery of the Standard Model from noncommutative geometry, or the more algebraic approached to quantum gravity of folks like Barrett, Crane, Isham, Rovelli or Smolin.

Saw where the String Theories are like islands in a swamp. When you drain the swamp to the bottom M-theory is the result that joins the islands as local peaks of the same mountain mass.
