Abstract: We compute correlation functions of closed strings in Misner space, which is a big crunch/big bang universe. We develop a general method for correlators with twist fields, which are relevant for the investigation of the condensation of winding tachyons. We propose to compute the correlation functions by performing an analytic continuation of the results in the $\mathbb{C}/{\mathbb{Z}}_{N}$ Euclidean orbifold. In particular, we obtain a finite result for a general four point function of twist fields, which might be important for the interpretation as the quartic term of the tachyon potential. Three point functions are read off through the factorization.
