Witten says string theory will fit in less than 11 dimensions

It was thought that 11 dimensional string theory and twisted space theory could not both be true but Witten says string theory does fit nicely into twisted space of 6 dimensions composed of 3 sets of complex space each of which has a real and an imaginary (sq root of -1) dimension.

Hum,
E8xE8` or SO(32) are needed for anomaly cancellation, imho.

Is it possible that it just a case that twisted space describes a `subset` of string theory, er, namely the 6 compactified spaces....(shot in the dark)

Sounds interesting,
Have you a link?

Don, I think that you are talking about twistor space theory. Witten is known for his efforts to try to unify strings with twistors

Shouldn't this be in Physics and Math?
