A new theoretical study proposes an alternative to black hole formation when massive stars collapse. Instead of creating a singularity within an event horizon, the collapse could trigger the birth of a miniature universe inside the star, driven by dark energy. This expansion would counteract gravity and prevent complete collapse, resulting in an exotic object called a gravastar rather than a traditional black hole.
Why it matters
This hypothesis challenges our fundamental understanding of stellar collapse and black hole formation. If proven correct, it could explain certain astronomical observations that don't align perfectly with standard black hole models and provide new insights into the nature of dark energy and spacetime.
What if some black holes aren’t black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the collapse could trigger the birth of a tiny new universe inside the dying star. Driven by dark energy, this miniature cosmos would expand and push back against gravity, preventing complete collapse and creating an exotic object known as a gravastar.
