Abstract

Understanding the Time-Asymmetry of Radiation Abstract In our experience, waves display a clear time-asymmetry: waves spread outwards after their sources move; they do not converge on sources in coordination with their motion. The laws governing wave phenomena, however, are symmetric in time. Where does the observed asymmetry come from? I discuss the nature of this puzzle and argue that its most common formulation is flawed. I consider a recent proposal due to Mathias Frisch. I argue that Frisch misconceives the puzzle and consequently misunderstands what his own solution amounts to. Finally, I suggest that the asymmetry of radiation results from the initial state of the universe.
