"Theoretical Proof of Traversable Wormholes in the Expanding Universe"
Astrophysicists from RUDN University have theoretically proven the existence of traversable wormholes in the Friedmann universe, connecting different universes or parts of the same universe. Their research, published in the journal Universe, explores the possibility of traversable wormholes in the general theory of relativity supported by dustlike matter. The study provides mathematical conditions for the existence of these wormholes and suggests potential observational signs for further research, including comparisons with cosmic voids and inhomogeneities in the universe.
