"Nested Gravitational Stars: Unraveling the Mystery of Russian Doll-Like Gravastars"
A new solution to Einstein's general relativity equations suggests the existence of hypothetical stars called "nestars," which could be made from stacked gravitational stars, or "gravastars," similar to Russian matryoshka dolls. Gravastars are compact bodies with dark energy cores, theorized as an alternative to black holes, and the new solution allows for a series of nested gravastars. While the existence of nestars is still uncertain, this research provides valuable insights into understanding black holes and exploring new solutions within the framework of general relativity.
