Singularity in the spacetime hole
Editor: Marek-Lars Kruusen
The field of gravitation is a curve in spacetime caused by extremely heavy masses. This curve in spacetime is expressed in the fact, that the more we move towards the centre of the field of gravity, the more time slows down and the shorter the distance between two points in space becomes. Such a transformation of time and space continues until a specific distance from the centre, and this distance is described to us by the Schwarzschild radius R.
This radius shows the distance from the centre of the field of gravity, starting from which time t and space l have transformed to infinity, i.e. starting from which the infinite curving of spacetime begins or the spacetime ceases to exist completely. This is why nothing can exist within the area inside Schwarzschild radius R of the black hole or spacetime hole, which is sometimes also called the event horizon.
This also means that there cannot be any singularity in the centre of the black hole. Singularity is just a point, starting from which the Schwarzschild radius R is measured and which determines the ‘size’ of the black hole or spacetime hole, i.e. the size of an imaginary sphere in space, starting from which the infinity curve of spacetime becomes more and more level as the distance from the centre increases.
This is why the mass of a black hole cannot exist within the event horizon, but is outside of it, as is also in case of stars and planets. The event horizon is completely spherical and it does not rotate. It can only orbit around another celestial body.
