Show affiliationsA brief review of the classical aspects of the absorber theory of radiation is presented. The divergences which arise from the use of time-symmetric electrodynamics are pointed out. It is shown that the earlier difficulties can be removed by attributing differing signal velocities to be advanced and retarded interactions. This difference in signal velocities is interpreted as arising from the extended, shell-like structure of charged particles. This leads to a new calculation of the absorber response. Absorption due to the time-symmetry normalisation factor is described. It is concluded that retarded radiation is approximately consistent in the Einstein-de Sitter model, whereas in the closed Friedmann model it is likely that retarded radiation is dominant during expansion, and advanced radiation during contraction. The theory predicts that advanced radiation exists in small amounts and can be detected experimentally.
