THE SUN - THE BLACK HOLE OF KERA
- Energy radiation of the Sun and prominences
- The sun is a black hole - a glowing ball or the usual Sun
- Magnetosphere of the Sun
- Coronal holes - a look into the negative space
- Gamma radiation of the Sun
For fifty years after the creation of the general theory of relativity, only Schwarzschild's solution describing a spherically symmetric black hole characterized by mass only was used in all calculations. The idea that sufficiently realistic models of black holes must have rotation is not new. Everyone understood that it was necessary to take into account the influence of rotation, but no one could correctly solve the rotation should depend on two parameters - the mass of the black hole (denoted by the letter M) of the Einstein equation. Strictly speaking, a complete solution of the gravitational field equations taking into account the angular momentum of the hole (denoted by a). In addition, this solution must be asymptotically flat, that is, far from the black hole, space-time should become flat. Although flat space never happens, but at a certain distance - up to the observed effect of a black hole, it can be assumed that it is flat. Like all assumptions in mathematical modeling, rejecting them leads to a revision of the entire model. Therefore, the assumption of an asymptotically flat space in mathematical models of black holes remains so far, so it does not have a significant effect on the structure of a black hole, but it proves to be unacceptable when considering a model of a space in which a black hole is an element of a more complex structure. The equations of the gravitational field turned out to be so complicated mathematically that no one could find a single exact solution for a long time that satisfied these simple requirements. Only in 1963, Roy P. Kerr, an Australian mathematician who then worked at the University of Texas (USA), found a complete solution of the gravitational field equations for a rotating black hole. For the first time almost fifty years after Einstein's fundamental work, astrophysicists finally obtained a mathematical description of the geometry of space-time surrounding a massive rotating object. By 1975, the uniqueness of the Kerr solution was proved. In exactly the same way as all possible solutions for black holes with only a mass (M) are equivalent to the Schwarzschild solution, and all possible solutions for black holes with mass and charge (M and Q) are equivalent to the Riesner-Nordström solution, all possible solutions with mass and the angular momentum (M and a) must be equivalent to the Kerr solution.
