	Although the gravitational constant (G)
does not explicitly occur in the Maxwell Wave Equations, this paper will show
that G is indeed implicitly contained
in them. The logical consequence hereby is that electromagnetic radiation is
associated with dynamic gravitation and not—as assumed in Einstein’s Special Theory of
Relativity—with
“static” gravitation, dynamic gravitation being at the time unknown. According
to the Maxwell Wave Equations, gravitation experiences the same dynamic (speed
of light c) as electromagnetic
radiation and must therefore also be of a quantum nature. There must exist an
equal number of gravitational quanta as there are photons. Since photons do not
possess a baryonic rest mass but only a relativistic mass, this mass must be
nonbaryonic in nature—precisely as their dynamic gravitation.

However, as G is inseparably associated with both the dynamic vector fields E and B<sup>1</sup> gravitation is—so to speak—“carried along” by the two vector fields to each other. Due to its coupling with E and B, gravitation must of necessity assume all the dynamic properties possessed by E and B<sup>2</sup>. Gravitation is thus propagated at the speed of light along the x-axis with the same frequency n as the electromagnetic wave. For this reason, gravitation must possess a wave property—i.e. radiation of a quantum nature.</p><p>Gravitational waves are—as is the case with electromagnetic waves—transverse waves and resonate synchronously in the plane of their respective field components E and B. Since G is expressed completely symmetrically in both of Maxwell’s Wave Equations (5), (6), the gravitational waves also obey Maxwellian theory in this regard.

Gravitational waves are therefore completely equivalent to the E- und B-fields of electromagnetic waves, albeit acting in an opposite manner. At the constant speed of light, a stable state of equilibrium exists within each photon between the expansive force of electrodynamics and the equal but opposing (braking) force of its dynamic gravitation. Therefore at the constant speed of light, the resulting total energy of every photon is always zero! This is an absolute necessity for the constancy of the speed of light.</p><p>This derivation represents a confirmation that photons as dynamic electromagnetic quanta are inseparably linked to dynamic gravitation (in the form of gravitational quanta).</p></sec><sec id="s3"><title>3.
