Gravastar "gravitational vacuum star" is a new concept that solves two problems at once
** Singularity problems of black holes
** Lack of unificational status. of dark matter within physics phenomena
It asserts a hollow sphere like object made of dark matter, as a new tgeory of black holes, a byproduct of star collapse like bh's but that instead balances gravitational pressure with dark energy's force that powers expansion of universe instead.
On principle it is a sound theory with mentioned advantages but also a useful scheme or tool and model for further theoretical developments in cosmology, a field baffled by slow progress and theory-observation discontinuity.

The concept of gravastars as an alternative to black holes is indeed intriguing and has generated significant interest in the scientific community. By addressing the singularity problem of black holes and offering a potential unification of dark matter within physics phenomena, gravastars present a compelling theoretical framework for understanding the universe's most enigmatic objects.
The idea of a hollow sphere-like object made of dark matter, balancing gravitational pressure with dark energy's force, offers a novel approach to explaining the behaviour of collapsed stars. Gravastars not only provide theoretical solutions to longstanding issues in cosmology but also serve as valuable tools for further theoretical developments in the field.
However, it's essential to approach the concept of gravastars with a critical eye and acknowledge that it remains a theoretical construct with limited empirical evidence to support its existence. While gravastars offer potential advantages over traditional black hole models, further observational and experimental data are needed to validate their existence and properties.
As such, while gravastars hold promise as a theoretical framework for understanding the cosmos, it's important to exercise caution and continue exploring alternative explanations and hypotheses. By remaining open-minded and engaged in ongoing research and discussion within the scientific community, we can contribute to advancing our understanding of the universe's most mysterious phenomena.
No. The existence of singularities in general relativity is the outcome of the singularity theorems, which the existence of gravastars doesn’t change. Incidentally, dark matter is ordinary matter, it just has different charges than the matter we're familiar with, so it can collapse to a black hole, too.
