Integrating field mass into gravitation results in a corrected
gravitation law, which deviates for very large distances from
Newton's description.
Furthermore its area of validity now has an upper (R0) and a
lower limit (r0), called reality barriers.

Any mass which is situated in the range between the upper border distance R0 and ρ must overcome a very weak repulsion force, if it wants to approach the source of field. Since this effect occurs only for very large distances, it is practically not observable. However the value of astronomical red shift can be acknowledged as result of this repulsion by computating this with Heim's corrected gravition law (see below).
For distances smaller than ρ the field now corresponds in good approximation to Newton's approximation. All empirical processes in space we are able to observe take place within this area.
This corrected gravitation law plays a key role in Heim's
mathematical calculations, because Heim says Gravitation is the
only physical background phenomenon which accompanies
all physical effects.
(This is a result of
equivalence of gravitation and inertia and a second equivalence of mass
and energy. Therefore all energy phenomena can be expressed by
matter-field-quanta).
Here is another fundamental thought of Burkhard Heim. He says
If gravitation is the general background phenomenon of physical
world, then there cannot be a world outside of the boundaries of
gravitation!
Therefore with this law it is possible now to
determine both the smallest thing in the world (fundamental geometrical
unit) and the largest thing existing – the diameter of the whole
world.
Now we will see, how this things are done.
First Heim was examining whether there would be a final geometrical
value, which remains still existing even if all masses are disappearing
in empty space. In fact such a value is calculable while transitioning
mass against 0, if you form a product between the lower reality border
of gravitation and Kompton's wave length of this infinitesimal
mass.
Interesting enough, this final geometrical unit then will be a surface.
It's size is approximately the square of Planck's length. (Heim
named it τ, because this letter existed coincidentally on his
typewriter).
The exact value of this metrons
(6.15 * 10-70
m2) describes the final geometrical unit of empty space,
where no mass exists. Real physical space – in contrast to
this – always is curved, whereby this elementary surfaces
become more or less compressed (condensed
) depending upon
densities of all fields existing in this space.
Just as the smallest thing of our world Heim also derives the largest
thing from the boundaries of gravitation law – the maximum
diameter of our physical world.
If you calculate an upper boundary R0 of the
gravitation law for the smallest mass conceivable (elementary
mass), you will receive the largest diameter for which gravitation law
really exists.

Finally Heim found that cosmic red shift too is a result of the corrected gravitation law. Therefore each particle of this world must approach primarily against the repulsive gravitation component of almost the whole remaining world. (This corresponds to the field curve between ρ and R0.) This is using energy whereby each photon becomes longer in it's wavelength during this journey.
Heim inserted estimated middle mass density of universe into his
formula and than he received as result Hubble radius, which is the
radius of our visible world. Each photon coming from further on behind
this radius has lost all of his energy.
Even observed exceptions in red shift are plausible now with this model.
They are only a result of inhomogenous mass density in space.
