NEW STRATEGIES FOR THE OBSERVATIONAL SEARCH FOR NONTRIVIAL STRUCTURES IN THE UNIVERSE

Sazhina O.S., Moiseev Iu.A.

In modern astrophysics and cosmology, it is important to search for non-trivial structures that acquire the status of classical ones due to their relevance for coordinating theory and observations. The Einstein gravitational theory predicts structures of nontrivial topology: the most promising are wormholes (WH) and solitary cosmic strings (CS). The effect due to the traversability of WH is discussed: stars on the other side of the neck exert a gravitational disturbance on the stars from the observer’s side. CS arise during vacuum phase transitions, as well as more exotic CS-like structures, the result of the evolution of multidimensional spaces of the pre-inflationary Universe. Defects in the form of CS are confirmed by a number of indirect observations; the systematic strategy for CS search is discussed. The observational identification of fundamentally new objects is made possible by a new theory and improved observation quality and is critically important for understanding the geometry of the Universe.
