Nonsingular black hole models

Nonsingular black hole models are theoretical constructs in the field of general relativity and theoretical physics that attempt to describe black holes without the singularities that traditional models, such as the Schwarzschild or Kerr black holes, predict. In standard general relativity, singularities are points in spacetime where the gravitational field becomes infinite, and physical quantities cease to be well-defined. This situation arises at the center of a black hole, leading to what is known as a gravitational singularity.
