| contents | We demonstrate that the experimental evolution of an annular, laser-driven plasma shock wave, expanding over time and undergoing self-interaction gives rise to multiple shock structures that evolve analogously to a multicomponent cosmological universe. Different propagation trajectories along the shock surface correspond to various forms of $w$CDM cosmologies, enabling the study of scenarios ranging from simple radiation- or matter-dominated universes to those including dark energy. We further show that the dynamics of the Mach stems approximately follows a Hubble-like law. Additionally, perturbations in the shock fronts serve as experimental analogues of cosmological gravitational perturbations in a matter-dominated universe. This work opens a new experimental pathway for classically simulating complex cosmological models and gravitational waves at macroscopic scales in the laboratory. |
