We know it is implausible that the local observable universe contains a near-balanced distribution of matter and antimatter because we fail to observe predicted anomalies of high-energy radiation brought about by spontaneous annihilation from matter-antimatter collisions on the borders of such antimatter regions. However, what about quasars, particularly high-energy gamma emitters? We may surmise that yes, this radiation is brought about by relativistic jets emitting Hawking radiation. But shouldn't the necessarily quantum nature of their production require at least some of this radiation to be composed of antimatter, at least in larger quantities than we observe locally? Combined with the fact we observe these severaly redshifted objects so far away, could we percieve this as evidence that antimatter may be more plentiful near the far fringes of the universe?
