The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a hypothetical cosmic object (a type of star or galaxy) that consists of antimatter. The hypothesis of the existence of antimatter and antiworlds was stated in 1933 by P. Dirac but has not been confirmed or disproved by observations. The electromagnetic radiation from stars and antistars is identical, so that it is impossible to distinguish between them by optical or radioastronomical methods. Other methods, such as those of neutrino astronomy, theoretically make these observations possible, since stars radiate mainly the neutrino and antistars, the antineutrino, but the existing apparatus (in the 1960’s) is not sufficiently sensitive. The problem of antiworlds became complicated after the discovery of violations of the law of conservation of parity (1957, 1964); it is not completely clear whether antiworlds should be represented, as before, as objects made of antimatter existing in ordinary space-time or whether they should be considered as existing in some “reversed” space-time.

His two first volumes of poetry, Parabola and Mosaics, were soon followed by other often imaginatively and sometimes modernistically titled works, among them "Triangular Pear" ("Treugol'naya grusha"), Antiworlds (Antimiry, 1964), Heart of Achilles (Akhillesovo serdtse, 1966), Shadow of Sound (Ten' zvuka, 1970), Let the Bird Out!
Airaudi's contribution "Hard to Be a God: The Political Antiworlds of Voznesesnky, Sokolov, and the Brothers Strugatsky" contends that the use of fantasy as a disguise has been a widespread habit among Russian writers and that the antiworlds created by these authors go beyond a mere response to conventional primary worlds since in fact they have provided much room for healthy dissent.
In this context of a literature that presents "worlds under erasure" (McHale, Postmodernist 99ff.), it seems particularly inappropriate to depict worlds and "antiworlds" as literary facts within a positivistically oriented theory.
