This is .
known as Quantum Gravity. In this realm, space and time are broken apart and cause and effect cannot be unraveled. Even .
today, there is no satisfactory theory for what happens at and beyond the rim of the singularity. A rotating black hole has an .
interesting feature, called a Cauchy horizon, contained in its interior. The Cauchy horizon is a light-like surface which is the .
boundary of the domain of validity of the Cauchy problem. What this means is that it is impossible to use the laws of physics to .
predict the structure of the region after the Cauchy horizon. This breakdown of predictability has led physicists to hypothesize .
that a singularity should form at the Cauchy horizon, forcing the evolution of the interior to stop at the Cauchy horizon, rendering .
the idea of a region after it meaningless. Recently this hypothesis was tested in a simple black hole model. A spherically .
symmetric black hole with a point electric charge has the same essential features as a rotating black hole. It was shown in the .
spherical model that the Cauchy horizon does develop a scalar curvature singularity. It was also found that the mass of the .
black hole measured near the Cauchy horizon diverges exponentially as the Cauchy horizon is approached. This led to this .
phenomena being dubbed "mass inflation." In order to understand what exactly a black hole is, we must first take a look at the .
basis for the cause of a black hole. All black holes are formed from the gravitational collapse of a star, usually having a great, .
massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, .
combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear .
reaction occurs and the gases within the star start to burn continuously. The hydrogen gas is usually the first type of gas .
consumed in a star and then other gas elements such as carbon, Oxygen, and helium are consumed.
