Considering the Einstein, Møller, Bergmann–Thomson, Landau–Lifshitz (LL), Papapetrou, Qadir–Sharif and Weinberg's definitions in general relativity, we find the momentum four-vector of the closed Universe based on Marder space–time. The momentum four-vector (due to matter plus field) is found to be zero. These results support the viewpoints of Banerjee–Sen, Xulu and Aydoġdu–Saltı. Another point is that our study agrees with the previous works of Cooperstock–Israelit, Rosen, Johri et al.
