A Dying Star Could Create a New Universe Instead of a Black Hole

A dying star could create a new universe instead of a black hole

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.

Big Bang inside a star: How a gravastar forms

Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses under its own mass until only a single point remains: the singularity. While the formation of a black hole appears plausible, black holes themselves continue to pose major challenges for science. How can ten billion solar …

Collapsing stars could form gravastars instead of black holes

A black hole is supposed to be the last word in stellar collapse: matter falls inward, spacetime caves in, and a singularity forms where the known laws of physics stop being useful. That picture has long made many physicists uneasy. Singularities are not just extreme objects. They are places where prediction itself breaks down. Black holes also hide everything behind an event horizon, raising unresolved questions about what happens to informatio…
