Physicist develops software solution to measure black hole stability
Although a Black hole It can be expressed in mathematical models, it does not mean it exists in reality. Some theoretical models are unstable: although they can be used to perform mathematical calculations, they make no sense in physics. A physicist from RUDN University came up with a way to find such unstable regions. The work was published in Dark Universe Physics Magazine
The existence of black holes was first predicted by Einstein’s general concept. These objects are so powerful that they cannot escape even the light. Dense and massive, black pits distort space-time shape (three-dimensional and one-dimensional physical construction). Many mathematical models used to describe black holes include mathematical adjustments for such spatial curves. The key to survival for each black hole model is stability with minimal spatial or temporal changes. The black holes in the math do not make sense. A physicist from RUDN University suggests a method for identifying black hole instability in 4D space-time.
“The black hole in which a model is supposed to be applicable must remain stable in the event of minor spatial changes. Academic and RUDN University Gravity and Cosmological Research Institute.
Physicists have studied stability in the Einstein-Gauss-Bonnet theory, which describes the black hole in Einstein’s equation with the fourth element. Previously, he focused on a different mathematical explanation for the black hole, called Lovelow Theory, which describes the infinite number of parts of a black hole. The instability region is found to be closely related to the values of the constants: the number of multipliers of Einstein equations.
According to the physicist, the Einstein-Gauss-Bonnet model does not provide for small black holes, because if the coupling constants are relatively large compared to other parameters (such as black hole radius), the model is almost always unstable. The stability of the joint is much larger than the negative value of the stabilization zone. Based on these calculations, he and his team developed a program to calculate the black hole stability based on any parameters.
Our approach is to try to stabilize black hole models. We have made the code publicly available for any of our colleagues to use to calculate instability for models with unspecified measurements. ”
