Cover Story: Time possesses a clear asymmetry between the past and the future; entropy increases, life evolves, we remember the past, and we plan the future. Yet fundamentally, our universe is governed by laws that are symmetric with respect to time reversal, making it difficult to identify a physical explanation for our experience of the irreversible passage of time. To reconcile this difference, we propose a toy model of emergent time asymmetries—the causal multibaker maps. After imposing a suitable initial condition and coarse graining on them, a Pearlean locally causal structure emerges. From this structure, we obtain not only the second law of thermodynamics but many additional time asymmetries resembling those of the real universe. View this paper
