• A network of domain walls would accelerate the expansion of the universe, but it would also exert a repulsive force expected to help the formation of large-scale structures. We used three-dimensional (3D) N-body simulations of the dynamical evolution of the formation of the structure under the assumption of various configurations of the domain wall network and obtained some cosmological observables: the cosmic Mach number, the velocity distribution, and the two-point correlation. We conclude by comparing the simulation-derived values with values derived from observational data that an era of the domain wall dominated universe can exist.
