A duet of physicists in the person of Luis Anchordoka and Eugene Chudnovsky from the City University of New York (USA) described a hypothetical form of life, the habitat for which is the incandescent body of a star. This life is based on cosmic strings (one-dimensional linear objects) and monopoles (particles with one magnetic pole). They could have formed when the quark-gluon soup after the Big Bang entered the stage of condensation and matter began to form in the universe.
The main postulate of scientists is that life in the Universe has a variety of forms, and is not at all similar only to earthly. Therefore, the criteria for its search are not the presence of water, carbon and certain temperatures on the exoplanet. Life is a form that carries information about itself and is able to reproduce faster than a single individual dies. In the case of biological organisms, this is a combination of DNA and RNA molecules that provide a self-replication mechanism, plus the ability of almost all living things on Earth to create several generations of offspring during the lifetime of an individual.
The existence of cosmic strings and monopoles has not been documented, but the mechanism of their existence inside stars is well described. Each monopole has at least two strings with which it can connect to other monopoles. Connections can be two- or three-dimensional, structures become more and more complex over time and at some stage separate under their own weight, creating a copy of themselves. This process requires the expenditure of energy, which is drawn directly from the star - which is why this strange life form chose them for its habitation.
Since there is a lot of energy inside the star, such a life is developing rapidly, often mutating, evolving and may well acquire intelligence. There was enough time for this, so that one cannot even exclude the development of interstellar flights by them in order to search for a new food base. The most interesting thing is that there is indirect confirmation of this theory - for example, stars like EPIC 249706694, which for some unknown reason fade much faster than expected. Is it because they are literally eaten by a strange stellar lifeform?
