Goethe University study suggests some black holes could be gravastars
Some black holes might not be what we thought.
A new study from Goethe University Frankfurt suggests that certain black holes could actually be gravastars: super-dense objects held together by dark energy, not a singularity.
Instead of swallowing everything with an event horizon, these gravastars form when a collapsing star creates a mini-universe inside, balancing gravity with dark energy.
Gravastars lack event horizons and singularities
Gravastars are pretty different from classic black holes. They don't have that infamous point of no return or an infinitely dense core.
The researchers say this idea could shake up how we understand the weirdest stuff in space.
As Professor Luciano Rezzolla puts it, It is essential to maintain an unbiased approach toward what we do not know and hence explore both the accepted wisdom and the more exotic interpretations. History teaches us that it is not unusual for the latter to become the former,
