Eduardo Martín-Martínez of the University of Waterloo and his collaborators have a novel proposal for transmitting information over cosmic distances: Using the disturbances created in an electromagnetic field by the emission of photons. The abstract of their preprint reads: We analyze the implications of the violations of the strong Huygens principle in the transmission of information from the early universe to the current era via massless fields. We show that much more information reaches us through timelike channels (not mediated by real photons) than it is carried by rays of light, which are usually regarded as the only carriers of information.
