Extremal black hole In theoretical physics, an extremal black hole is a black hole with the minimal possible mass that can be compatible with a given charge and angular momentum. In other words, this is the smallest possible black hole that can exist while rotating at a given fixed constant speed. The concept of an ext... | https://en.wikipedia.org/wiki?curid=681802 |
Near-extremal black hole In theoretical physics, a near-extremal black hole is a black hole which is not far from the minimal possible mass that can be compatible with the given charges and angular momentum. The calculations of the properties of near-extremal black holes are usually performed using perturbation theory ... | https://en.wikipedia.org/wiki?curid=681806 |
