Abstract
The article discusses the prevention of the formation of black holes as a result of quantum effects and how these effects may give rise to dense entities called black stars instead. Topics include an overview of the theoretical physics of black holes, such as Einstein's field equations from his general relativity theory, a description and analysis of black holes, which are regions of curved spacetime with intense gravitational fields, and the paradox of quantum black holes.
