@article{Orlov_2021, title={Origin and Physical Properties of the Black Hole}, volume={2}, url={https://sriopenjournals.com/index.php/engineering_technology_review/article/view/98}, abstractNote={<p><em>A new physical model is proposed for the appearance of an astronomical object - the Black Hole. It is shown that the Black Hole is the center of the cosmic, etheric, gravitational torsion. An equation for determining the radius of this object based on the theory of vortex gravity is presented. A substantiation is proposed that the force of gravity on the surface of the Black Hole does not depend on the mass of this Black Hole. The mass of the Black Hole cannot be determined. A contradiction is shown in the Schwarzschild solution by the definition of the radius of the Black Hole.</em></p>}, number={2}, journal={Engineering & Technology Review}, author={Orlov, Sergey}, year={2021}, month={Oct.}, pages={10-15} }
