A dying star could create a new universe instead of a black hole
ScienceDaily • • science
Key Points:
- Black holes, while widely accepted, pose unresolved questions about singularities and the limits of known physics, as they conceal all matter and information beyond their event horizons.
- Gravastars are proposed ultra-compact objects filled with dark energy instead of singularities, potentially preventing complete collapse and offering an alternative to black holes without event horizons.
- Theoretical physicists Daniel Jampolski and Luciano Rezzolla have presented a dynamic solution to Einstein's equations suggesting that a collapsing star could spawn a mini universe inside it, whose expansion halts collapse and forms a gravastar.
- This model provides a first explanation for how gravastars might form from ordinary matter collapse, involving new physics at extreme densities and drawing parallels to the Big Bang's expansion driven by dark energy.
- The researchers stress that exploring gravastars does not negate black holes but encourages open-minded investigation into both conventional and exotic outcomes of gravitational collapse.
