Antimir - a hypothetical space object (it can be a star , galaxy , black hole or metagalaxy [1] (anti-universe [2] )), consisting of antimatter [3] . Anti-world anti-universe is considered quite similar to ours [2] . If it turns out that the radiation of matter and antimatter is at least slightly different in frequency , this will mean that the anti-world anti-universe is not completely identical to our world [4] .
Also called the antiworld is a set of antiparticles [5] .

History
The hypothesis of the existence of antimatter and anti-worlds was expressed in 1933 by P. Dirac , but, unlike the existence of antimatter, the hypothesis of the existence of anti-matter is not confirmed or refuted by observations. The electromagnetic radiation of stars and anti - stars is identical (so photons are truly neutral particles ), as a result of which they cannot be distinguished by optical and radio astronomical methods.
Other methods, such as neutrino astronomy methods, in principle allow this to be done (stars emit mainly neutrinos , anti-stars - antineutrinos ), but the existing equipment (60s of the 20th century) is not sensitive enough.
In the 1960s, B. Konstantinov hypothesized that if anti-worlds exist, then sufficiently large bodies from antimatter should reach the Earth [6] .
The problem of antiworld became more complicated after the discovery of violations of the law of conservation of parity (1957, 1964). As a result, it is not entirely clear whether the antiworld should still be represented as objects from antimatter, but located in ordinary space-time , or whether they are in some “reverse” space-time.
In 1964, Gustav Johannovich Naan put forward the hypothesis of a symmetrical Universe, according to which along with the ordinary world there is an anti-world [7] .
It has now been established that significant objects consisting of antimatter in the Universe do not exist. This phenomenon is called baryon asymmetry [8] . The reasons for the imbalance between matter and antimatter are explained by the violation of CP invariance [9] .
In art
The existence (in one form or another) of the anti-world is one of the important fantastic assumptions used in the works of the science fiction genre.
