A dying star could create a new universe instead of a black hole
Physicists are exploring the concept of 'gravastars' as a theoretical alternative to black holes to resolve contradictions in current gravitational theories. Unlike black holes, which contain a singularity, gravastars are hypothesized to be composed of dark energy, avoiding the mathematical issues of infinite density.
Why it matters
This research addresses fundamental questions about the nature of spacetime and the limits of current physical laws.
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. The star begins collapsing under its own weight, theoretically continuing until all of its mass is compressed into a single point known as a singularity.
The article provides a purely scientific overview of a theoretical physics debate.
