Scientists reveal dying star could create 'whole new universe'

Scientists found a dying star could create a new universe instead of a black hole.

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.

Theoretical physicists Daniel Jampolski and Professor Luciano Rezzolla from Goethe University Frankfurt have discovered a new mathematical model showing that the collapse of a dying massive star can trigger the birth of a miniature expanding universe inside the collapsing matter itself.

As the mini universe expands, it pushes outward against the inward pull of gravity. This opposing force can halt the collapse before a black hole forms.

Preventing the Black Hole SingularityIn standard astrophysics, when a giant star exhausts its nuclear fuel, its radiation pressure drops.

Under conventional theories, Gravity wins, violently crushing the stellar matter inward.

The result is a stable balance between the collapsing stellar material and the expanding interior universe. That balance creates a gravastar.

Massive stars produce light and heat through nuclear fusion, a process that releases enormous amounts of energy from their cores.

Eventually, however, the largest stars run out of fuel. Once that happens, the outward pressure generated by radiation is no longer strong enough to resist gravity.

Because of these unresolved issues, some researchers have explored the possibility that at least some objects identified as black holes could actually be something else entirely. 

While this collapse continues indefinitely until all matter condenses into an infinitely small, dense point known as a singularity—the heart of a black hole where the known laws of physics completely break down.

Additionally, one proposed alternative is an ultra compact object known as a 'gravastar.'
