Nevertheless, we show that it has difficulty accounting for certain details pertaining to drifting subpulses, nulling, and mode changing. Once positioned in its vicinity and properly shielded from its cosmic ray flux, a properly equipped spaceship could project a maser beam to an ionized region in the star's corona and phase conjugate microwaves reflected back to the maser to produce a self-amplified, phase conjugate soliton beam between the ship's maser generator and the star's corona [ 1112 ]. The reason they gave for their reassessment was that they felt it was highly unlikely that more than one civilization would be transmitting a message to us at the same time. Moreover the one-radian symbolism that they convey is relevant to their location. As discussed in Section 3, besides the Galactic center, there are three principle sky positions viewable from our solar system where a civilization could site a communication beacon and be assured that their signal would be interpreted as an ETI message through its reference to the Galactic center, these being the galactic anticenter location and the northern and southern locations along the galactic equator that lie one radian from the Galactic center.
My attempt to explain pulsar characteristics in terms of a natural cause first began in while a doctoral student at Portland State University.
How short is a midget
But, if one surmises that the Crab and Vela pulsars are part of a message alerting us to such a superwave, it is not much of a leap of induction to infer that a galactic equator sky location situated one radian from the Galactic center would be very significant in the context of this message, in that it marks the angular distance of a line segment vector that extends between the Galactic center and our solar system. So one might ask, in drawing these conclusions about the Millisecond and EBM pulsars whether the author was projecting the presence of a pattern in what may be inherently random pulsar arrangements. But they attempt to explain the second feature by assuming that the main pulse and interpulse come from opposite poles of the neutron star and that the pulsar's axis is spinning end-for-end relative to our line of sight so that first one pole and then the other shines in our direction. Since the time that it was discovered, only two pulsars have been found which have sky positions closer to the GC by about 8 minutes of arc. Besides exhibiting very high precision in the timing, shape, and polarization of their integrated pulse profile, they also exhibit a variety of subpulse and pulse profile ordering characteristics which give each pulsar additional unique features in their signal signature.
