(1) The simulations start from a galaxy distribution based on primordial density fluctuations and (2) performs gravitational many-body calculations to evolve to the current galaxy distribution. (3) Then the reconstruction method is used to work backwards to the earlier galaxy distribution. (4) Finally, the reconstructed galaxy distributions and initial conditions are compared. This research found that the statistical properties of the reconstructions are very similar to the initial conditions.
