Twistor String theory is an equivalence between Supersymmetric Yang-Mills theory and the peturbative Topological B model string theory in twistor space][Twistor String 1] It was initially proposed by Witten in 2003. This is considered a major breakthrough by many as before Witten's 2003 paper, Twistor theory was only applicable to Classical General Relativity. [1]
Since the dimensionality of Twistor space is necessarily the same as 4-dimensional spacetime with metric signature , i.e. 1 time and 3 space, this is also a way to do away with the extra dimensions of string theory.
