Universal principle of mass

Mass is a measure for occurrence of space in time.
Since the gravitation is measure for which space-time stretches in dilatational fraction of time, the existence of space-time and mass is determined by gravitation.
Therefore, since the state of rest is in fact interrupted free fall, the natural state of a body is a free fall.
The stabile state of orbits is their stretchiness caused by gravitational dilation. Since the acceleration is advance of gravitation, change of acceleration is in fact change of gravitation. That change (increasing or decreasing acceleration) causes the orbits to deform (stretch or contract) i.e. it causes greater or smaller occurrence of space upon dilation. The bigger mass has the greater occurrence of orbits per unit of space, which causes the greater resistance of a body to change its acceleration.
Since

change of gravitation is a change of dilation with consequence of RF change.
Furthermore, because

i.e. two dilations as a consequence of orbital velocity equals to one orbital gravitational dilation, means that any change of velocity results with change of dilation.

Since change of dilation means energy

to change the dilation the contribution of work is required.
The manifestation of that is inertia.
Inertia is a resistance of a system to change its dilation, and it is equivalent to energy required to perform that change.

Weight “W” is a manifestation of inertia when the direction of velocity which changes the speed of a body in a free fall is opposite to direction of gravitation and is equal to a product of mass and that velocity

In the state of rest, when the body wants to fall at acceleration “a” but is trapped, it equals to a power of mass and acceleration of space fraction in which we perform measuring.

From including in Newton’s equation for mass;

and assuming that gravitational constant “G” is in fact dilation of light second space fraction at acceleration on a celestial body surface

we have;

which derivation is the equation for mass:

Since

it is equivalent if we write;

Therefore, mass equals to a product of light speed fourth power and dilation of light second space fraction as well as to a product of light speed third power and a light second space fraction gravitation.
From given equations, the space three dimensional and the space-time fourth dimensional aspect is evident. It is also obvious that mass changes space (g) - time (d) and vice versa.

Furthermore, it comes forth that gravitation of light second space fraction equals to  mass divided by light speed third power;

and that speed of light equals to a third root of mass upon gravitation of light second space fraction;

Since gravitational dilation of a light second space fraction equals mass upon fourth power of light speed;

comes forth the equation for dilation as a consequence of orbital velocity;

From those equations follow the relations for orbital velocity, escape velocity and light speed;

Derive from there, we have that mass equals to a product of orbital velocity power and power of speed of light as well as to a half of that amount for escape velocity;

Since

mass can be expressed as a product power of light speed, acceleration and radius;

The equations for mass set forth corrects wrong measurements for celestial body masses due to use of gravitational constant, which is in fact gravitational variable. Those results for mass are in fact relative values calculated from our RF with our space-time units.
The results of introduced equations satisfy the principle off masses, dilations and energy relation equivalence;

Gravitation, orbital and escape velocity as well as all other space-time manifestations through which the masses of the bodies where calculated by use of gravitational constant remain unchanged.
