  The Einstein equations are non-linear and the particles of which the
gravitational effect is described by these equations are lastly unknown. If
renormalizable fields are assumed, then results are obtained only in the case
of a at space. Therefore, there is still no generally recognized quantum theory
of gravitation and electromagnetism. In this work the solution of these quantum
mechanic problems are forced in some sense: the metric tensor is linearized,
and it is required that the entire system of equations is invariant with
respect to the symmetry group of the linearized Einstein equations. The field
which represents this symmetry group only allows a measurement within the
horizon to simulate the event horizon. It is shown that the number of quants of
this field is constant. There are 4 types of solutions in the 2-quantum space,
of which one has particle-like properties. This particular solution has a
gravitational effect which can be externally arbitrarily small, as compared to
its electromagnetic effect. In contrast, this does not apply to the other 3
solutions. The model might be used to explain why gravitation is so much weaker
than the electromagnetic interaction in real physics. Accordingly, the Higgs
boson is possibly not necessarily be required for the mass scale. Likewise, an
explanation could be made why gravitation and electromagnetic inter- actions
had the same intensity during the early stages of the universe. A peculiarity
of the model provides a mechanism for the Big Bang in all four types of
solutions, although there is no singularity. As a consequence of the inferred
change in the microstructure, a change in the macrostructure of the cosmos is
suggested, allowing an understanding of the particular properties of the Dark
Matter and the accelerated expansion of the cosmos.
