Intelligent communication. Since 1967, astronomers have been receiving and cataloging very precisely timed radio pulses coming from sources they call pulsars. They have long assumed these to be natural sources, exotic spinning stars that emit laser-like radio beams that sweep through space much like lighthouse signal sequences. Highly regular flashes and complex signal ordering are produced through intelligent modulation of their beam s intensity and direction of polarization. More significantly, through their seemingly purposeful geometrical alignments, pulsars appear to be conveying a coherent message. Are these beacons from an intelligent origin? And are they warning beacons to warn us against the next shockwave that comes of the active galactic nucleus ore want they attack us? It might be prudent to consider whether we are talking about friends or foes.....Mike Storm.
