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 can not be determined. A contradiction is shown in the Schwarzschild solution by the definition of the radius of the Black Hole.

According to many astrophysicists, astronomical object the Black Hole (BH) is an area in the space which gravitational attraction is so great that light quanta can't leave it even. Researchers believe that Black holes could result from catastrophic gravitational collapse of a massive star at that historical moment when it dies. At collapse - catastrophic compression of a star - intensity of gravity over its surface becomes so terribly big that the space surrounding a star - time is displaced. This star disappears from the Universe and there is only strongly bent area of space - to time. The border of this area is called as gravitational radius. Spherically a symmetric black hole it is equal in the elementary case to Shvartsshild's radius. Theoretically possibility of existence of such areas of space - time follows from some exact solutions of the equations of Einstein, first of which was received by Karl Shvartsshild in 1915 [1].

Where,** r _{s}** – the radius of the Black Hole,

At such radius and the corresponding volume, the mass of this BH has to be on the basis of a formula (1) about 10^{39} kg. Then density of the Black Hole in the center of our galaxy has to be about 5 kg/m3! ? On the basis of the classical equation about a mutual attraction gravitation force on a surface of the Sagittarius A * is equal

**F = ** ** 6.8 x 10 ^{4} **

Agree, it is impossible to call this Black hole "catastrophically squeezed", and gravitation forces on its surface "terribly big". It is obvious that the theoretical explanation of an astronomical phenomenon of the Black hole doesn't correspond to physical parameters. In addition, equation (1) is mathematically absurd. In it, the quantities (G) and (c) are constants. Therefore, the mass of the Black Hole (M) is directly proportional to its radius (r). In fact, the mass of any body is always proportional to its volume. The volume is proportional to the radius of this body in the cube (r3). Then the mass must also be proportional to the radius in the cube. From this discrepancy with the laws of mathematics of equation (1) it follows that the density of the Black Hole (P) is inversely proportional to the root of its cubic radius.**P ~ r-1/3**

Example, On the basis of formula (1), we shall determine the mass of the Black Hole with a radius equal to 1 m.

Then the density of this black hole is

This density is several orders of magnitude greater than the density of the nucleon. Consequently, equation (1) is absurd. It is offered to study the theory of vortex gravitation and cosmology below. On the basis of this theory it is possible to explain genesis of the Black hole without contradictions.

The theory of vortex gravitation [3] is based on the well-known astronomical fact – all heavenly objects rotate. The most logical explanation of the reason of this movement can be only one – rotation of heavenly objects generated vortex rotation of space substance – ether. Ether forms system of the interconnected whirlwinds in world space. Orbital speeds of ether in each tuft (torsion) decrease in the direction from the center to the periphery under the law of the return square of this removal. If orbital speeds of a stream of ether decrease then, under aerodynamics laws, pressure in this stream increases. The gradient of pressure generates pushing out force in the direction to zones with the smallest pressure, that is to the center of this torsion. We will consider the equation of vortex gravitation received in the theory [3]. In this section, a model of appearance of the gravitation attraction force is considered from the viewpoint of aerodynamics. Namely, the two-dimensional model is considered on the basis of the following initial postulates. These postulates will be expanded and defined more exactly below.

**Figure 1:** Two-dimensional model of gravitational interaction of two bodies.

Forces operating on a body 2 are specified. The F_{c}-centrifugal force, F_{p}-force of an attraction of a body 2 from a body 1, v_{2} – the linear speed of a body 2 on an orbit, R – the radius of an orbit, r_{1} – the radius of a body 1, r_{2} – the radius of a body 2, w_{1} – the angular speed of rotation of air on a surface of a body 1, m_{2} – body weight 2.

As it was already spoken, movement of a whirlwind is resulted by pressure gradient. Radial distribution of pressure and ether speed in work [3] are defined on the basis of Navier-Stokes's equation for movement of viscous liquid (gas).

In cylindrical coordinates taking into account radial symmetry of v_{r}=v_{z}=0, v_{j}=v (r), P=P (r) the equation will register in the form of system

Where **r**** = 8.85 ****х** **10 ^{-12 } **kg \m

In cylindrical coordinates for the module of force of gravitation

Then comparing (3) and (4) for incompressible ether **(****r****=const**) we find that

After necessary transformations (full calculation is stated in the theory [3]) it is received:

1 . the equations for determination of force of gravitation depending on the speed of rotation of ether

r_{n},_{ }m_{n } – radius and mass of a nucleon.

We will transform a formula (6). We will equate **r _{1} = r**. We will substitute

2. The equations for determination of dependence of pressure of P_{0}, from the speed of rotation of ether of V_{1}

Where – pressure of ether on we consider P_{0} to an orbit, using a boundary condition

In fig. 2 pressure distribution according to a formula (8) is graphically shown.

**Figure 2:** Radial distribution of pressure of air for the Sun.

Асcording to laws ether-loudspeakers [4] pressure in motionless air is accepted size

Ether density

By means of the equation (8) we will find the orbital speed of ether of V_{0} = V_{1} at which pressure of P_{0} will be equal to zero.

from where_{ }

where

R_{0 } – radius of an orbit of a whirlwind on which ether reaches speed

R_{kn }– radius of an orbit of a whirlwind in which the speed of ether is known (V_{kn}).

From the equation (9) we find the orbital radius of the radio torsion with zero pressure.

Orbital speed of ether of V_{kn} is determined by the known force of gravitation in the same orbit, by means of the equation (7).

We will consider the Sun address in a galaxy orbit.

Orbital speed of solar system -**V = 2.2 *** **10 ^{5}**

Radius of an orbit of solar system **-** ** V _{kn} = 2.46*10^{20}** [5].

We determine the centrifugal force operating on the Sun.

Provided that centrifugal forces, in any point of an orbit, are always equal to attraction forces, we find force of the galactic gravitation operating on the Sun.

** **We substitute value** F _{п}** and

Radius of an orbit of astronomical object the Sagittarius* with the zero pressure upon surfaces, on the basis of the equation (10)

** _{ }**The strength of the vortex gravitation on the surface of a black hole

*F _{g }= 620 x M*

Similarly, we find radiuses of Black holes at other objects:

Sun - *R0* = 155500 m

Eartht - *R0* = 0.478 m

Obviously, the modern theory of the origin of black holes contradictory. On the example of a celestial object Sagittarius A* can be argued that Black holes are not superdense and supermassive objects. They may not have a huge force of gravity at its surface. Based on the theory of vortex gravitation and cosmology, black holes is the central region of space, ether, gravitation torsion. Orbital velocity of the ether on the surface of this area reaches the maximum possible value

At this speed, the pressure on the rotationorbitof theesterdecreases to zero. No substanceorradiation is notable tobreak out ofthis zone.Therefore, the centerspace, gravitation torsioninvisible.Insidethe black holerotationetherorstopsorslows down. In this case,there can existinside a black holeof antigravity.

**Note****.** A similar phenomenon is noted in the center of tropical meteorology and sea storms. Where there is complete peace of mind (calm). This phenomenon is called the "eye of the storm." Radius of the black hole Sagittarius A * at the center of our galaxy observations to determine the magnitude

The estimated value of the radius of the black hole Sagittarius A *, obtained in Chapter 4 (1,382×〖10〗^14 m) higher than the observed value of two orders of magnitude. This is not a calculation error, and the inequality of the radii of the Black Hole in the longitudinal (orbital) and transverse (axial) dimension. The fact that black holes have their form likeness forms of galaxies - and the disk are located in outer space, in the same direction as the galaxies themselves. Terrestrial observer is on the periphery of our galaxy and it can measure their visual observations center of the galaxy (Sagittarius A *) only in the transverse axial dimension. At the same time, disk Sagittarius A * its plane directed to us, so we can determine the calculations only the distance in the longitudinal direction radially. Therefore, calculations determined the orbital radius, and observations - transverse axial thickness of the black hole Sagittarius A *. Radius of gyration of any cosmic torsion far exceeds its axial thickness. For the black hole Sagittarius A * this fact recorded in this paper calculations and astronomical observations.

Gravitational torsions can be of different sizes. Each torsion creates its material object. Micro torsion create atoms. Planetary - planet. Star - star. Galactic - galaxies. Universe - the universe. All torsions in their centers hase black holes. In celestial bodies (atoms, planets, stars, etc.) they are under a layer of the material of which they are created. Therefore, they are hidden from us. In large space objects such as galaxies, they are open and subject to study. Modern classic exercise in cosmology and astrophysics have a lot of controversy for one reason. All of them are based on a global error of the classical theory of gravitation, which states that all bodies create gravity. In fact the opposite is true - gravity creates the body.
