Violation of the strong Huygen's principle and timelike signals from the
  early Universe
  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.
