likely.
Another well-known fact testifies to delay the speed of rotation of celestial bodies in the process of evolution – a decrease in the rate of rotation of stars in the Main sequence. It is assumed that at the initial stage of evolution the equatorial rotation speed of the stars reaches 10 – 100 km / s. At the stage at which the Sun is located, it is 2 km / s, and continued to decrease until the release of the Main sequence.
Consider the possibility of quantifying the approximate viscous braking of the rotating cosmic body due to its shear interaction with the physical environment (physical vacuum).
Figure 1 show a diagram of this interaction, which can be used to calculate the "viscosity" of the physical vacuum. Rotating cosmic body (1) with a radius R slows its rotation under the effect of tangential force f, which is caused by the viscous resistance of the surrounding physical environment (physical vacuum). The linear velocity of the medium at the equator is the linear velocity of the body v. As the distance from the center of the body linear velocity of the medium due to its viscosity decreases to zero at the boundary of the action of the gravitational field of a rotating body at a distance Rg. To calculate the viscosity can use the Newton's law:
f = μ. (Δv / ΔR). s, (1)
where f – tangential force, causing the shear of the physical environment, μ – viscosity coefficient, Δv / ΔR – velocity gradient and s – area of the layer on which there is a shear.
Using the expressions (1) to and date on the slow the rotation speed of the Earth earlier [3] was calculated the viscosity of the physical vacuum and then after the resulting viscosity a value was estimated the deceleration of the Sun rotation speed.
Fig. 1. Scheme of braking speed rotation of the cosmic body due to the viscosity of the physical vacuum: 1 – rotating body, 2 – border effect of the gravitational field of a rotating body, f – tangential braking force, v – equatorial velocity, R – radius of the body, Rg – radius of the sphere of action of the gravitational field formed body.
Also, based on indirect evidence can be seen on the property of the physical vacuum, undergo longitudinal and shear deformation. Moreover, due to the high modulus tensile longitudinal strain apparently is small. Shear deformation occurs during the formation of gravitational waves, which, by analogy with electromagnetic are apparently cross.
3. The gravitational field of a stationary body
Cosmic body creates around itself a force field – the gravitational field. The main characteristic is its gravitational strength tension at any point. It characterizes the force which acts on a point located in this different body. The tension is given by:
g = F / m, (2)
where g – the field strength (tension), F – gravitational force, m – mass of the test body made to the field.
The gravitational field can be described analytically by calculating it's intensity for each point of the field or graphically, causing tension in the plot line or field lines. An example of a graphic image of the gravitational field is shown in Figure 2. Power lines or tension lines (1) begin at cosmic body (2) and extend into the surrounding space according to the formula (2) to infinity. When interacted many bodies the line tension can take a curved shape and then on the graph the field strength can be characterized by density of the location of power lines.
Fig.2. Schematic representation of the gravitational field: 1 – line tension (power line), 2 – cosmic body.
In accordance with the above concept to consider the surrounding physical environment induced in her gravitational field as elastic-viscous body can be assumed that this body has the ability to tensile strain and shear. The greatest interest is the shear deformation, which during rotation of the body can cause a concentric orientation of the force lines and thus reduce the resistance of the field orbital motion space bodies.
4. The gravitational field of a rotating body
The interaction of a rotating body with elastic-viscous gravitational field, like other elastic-viscous fluids (liquids, gases) can be considered within the theory of dynamic boundary layers. However, with a persistent finding in the literature [4], it is almost not possible to find data on formation the boundary layers the rotating bodies.
The closest well-studied case can be considered a tear flow when the fluid flow separates from the surface of the curved shape. At the front of the body curved shape (Fig. 3) the flow velocity in the boundary layer decreases from the value v0 on the outer edge of the layer and to v = 0 on the body surface, At the point s there is separation of a laminar boundary layer, and turbulization of the flow.
Fig. 3. The scheme of formation of separated flow around the flow body with a curved generatrix: v0 is the flow velocity, s – point margin, δ – thickness of the boundary layer.
Given that according to the accepted concept to consider the gravitational field as a viscous-elastic medium, we can assume that during the rotation of a celestial body around it will produce dynamic laminar layer δ, the thickness of which will depend on the mass and speed of its rotation and to meet space scale (tens to hundreds of thousands of miles).
Figure 4 provides a diagram of the dynamic boundary layer (2) of the gravitational field on the surface of a rotating spherical celestial body (1). The body rotates at a linear velocity v0. Due to the viscosity of the environment (physical vacuum) formed in the boundary layer, the velocity gradient. On the body surface at point s, the velocity of the particles of the physical environment is equal to the linear velocity of the body vo. As the distance from the surface it drops to zero at the surface boundary layer.
Fig.4. The formation of a boundary layer δ around the rotating sphere: 1 – rotating sphere, 2 – laminar boundary layer, 3 – turbulent boundary layer, vo – linear speed on the surface of a sphere, s – point separation, fg is the gravitational force, fc is the centrifugal force,
At point s on the boundary layer, there are several forces that seek to tear it from the body surface. Most of this is centrifugal force fc due to rotation of the body. Another force that is oriented on the boundary layer separation is a normal component of the force is the viscous resistance of the physical environment fv. Has a certain value of the normal component of the inertial force fi, although in the modern sense of the properties of the physical vacuum is hard to speak about its mass (dark matter!). These forces are balanced by gravitational force fg, so that the formation of a boundary layer around the rotating spheres equality:
fg = fc + fv + fi, (3)
For a laminar boundary layer lies a turbulent layer δt (3). However, the turbulent layer, apparently, can occur directly on the surface of the body, if the three components of the breakout forces in equation (3) will be greater than the gravitational force.
Of great importance is the velocity gradient in the boundary layer. Thanks to the difference of the layer velocity will be concentric (tangential) orientation of the force lines that will lead to such changes in the properties of the gravitational field in which the orbital moving body will not cross the power lines and expend energy on their intersection. Due to the concentric orientation of the power lines appear energetically favorable orbit on which the appeal cosmic bodies will be without energy consumption.
