Gravastar Filled With Dark Energy Counters Stellar Collapse

Gravastar Filled With Dark Energy Counters Stellar Collapse

The collapse of a star may result in a gravastar, an ultra-compact star resembling a black hole, rather than a singularity. Calculations using Einstein’s General Relativity suggest a new mini universe, filled with dark energy, could form inside the collapsing star and counterbalance gravity.

Gravastar theory offers alternative to black holes during stellar collapse

New gravestar theory suggests some collapsing stars could form gravastars instead of black holes. Find out more.

Big Bang inside a star: How a gravastar forms

A new relativity model suggests gravastars could form when dark energy creates an expanding mini-universe inside a collapsing star, preventing a black hole.

A Big Bang Inside a Dying Star Could Stop Black Holes from Ever Forming

The most extreme objects in the universe might not exist. Black holes, those monsters of collapsed matter that anchor whole galaxies and bend light around themselves, have a problem at their core, quite literally: a point of infinite density where the laws of physics simply give up. Now two theoretical physicists in Frankfurt have worked out a way for nature to dodge that embarrassment entirely. Their answer involves something rather startling, …
