Twistor String theory is an equivalence between $ \mathcal N=4 $ Supersymmetric Yang-Mills theory and the peturbative Topological B model string theory in twistor space] [1] It was initially proposed by Witten in 2003. This is considered a major breakthrough by many as till Witten's 2003 paper, Twistor theory was only applicable to Classical General Relativity. [2]

Since the dimensionality of Twistor space is necessarily the same as 4-dimensional spacetime with metric signature $ \left(-+++\right) $, i.e. 1 time and 3 space, this is also a way to do away with the extra dimensions of String Theory.
