Consider a system of small hard spheres, which are initially (almost) independent and identically distributed.

    Then, in the low density limit, their empirical measure $\frac1N \sum_{i=1}^N \delta_{x_i(t), v_i(t)}$ converges
    almost surely to a non reversible dynamics.

      Where is the missing information to go backwards?
