Is there an antimatter-universe or antigalaxy?

Summary The very recent measurements on the ratio of cosmic antiproton to proton have contradicted seriously the previous measurements of the same for low-energy antiprotons. The controversial situation has been described and its implication for the validity of the postulate about the existence of antigalaxy has been examined. Although a very decisive conclusion cannot yet be made, a two-component behaviour of the ratio cannot, however, be excluded. Moreover, this two-component proposition seems to have better prospectsvis-a-vis the high-energy measurements of the ratio.
