Abstract: Starting from the action function, we have derived a theoretical background that leads to
the quantization of gravity and the deduction of a correlation between the gravitational and the inertial
masses, which depends on the kinetic momentum of the particle. We show that the strong equivalence
principle is reaffirmed and, consequently, Einstein's equations are preserved. In fact, such equations
are deduced here directly from this new approach to Gravitation. Moreover, we have obtained a
generalized equation for the inertial forces, which incorporates the Mach's principle into Gravitation.
Also, we have deduced the equation of Entropy; the Hamiltonian for a particle in an electromagnetic
field and the reciprocal fine structure constant directly from this new approach. It was also possible to
deduce the expression of the Casimir force and to explain the Inflation Period and the Missing Matter,
without assuming existence of vacuum fluctuations. This new approach to Gravitation will allow us to
understand some crucial matters in Cosmology.

1. INTRODUCTION
Quantum Gravity was originally
studied, by Dirac and others, as the
problem of quantizing General
Relativity. This approach presents
many difficulties, detailed by Isham
[1]. In the 1970's, physicists tried an
even more conventional approach:
simplifying Einstein's equations by
assuming that they are almost linear,
and then applying the standard
methods of quantum field theory to
the thus oversimplified equations. But
this method, too, failed. In the 1980's
a very different approach, known as
string theory, became popular. Thus
far, there are many enthusiasts of
string theory. But the mathematical
difficulties in string theory are
formidable, and it is far from clear that
they will be resolved any time soon.
At the end of 1997, Isham [2] pointed
out several "Structural Problems
Facing Quantum Gravity Theory". At
the beginning of this new century,
the problem of quantizing the
gravitational field was still open.
In this work, we propose a new
approach to Quantum Gravity.
Starting from the generalization of the
action function we have derived a
theoretical background that leads to
the quantization of gravity. Einstein's
General Relativity equations are
deduced directly from this theory of
Quantum Gravity. Also, this theory
leads to a complete description of the
Electromagnetic Field, providing a
consistent unification of gravity with
electromagnetism.
2. THEORY
We start with the action for a
free-particle that, as we know, is
given by
∫−= ba dsS α
where α is a quantity which
characterizes the particle.
In Relativistic Mechanics, the
action can be written in the following
form [3]:
dtcVcLdtS
t
t
t
t∫ ∫ −−== 21 21 221α
where
221 cVcL −−= α
is the Lagrange's function.
In Classical Mechanics, the
Lagrange's function for a free-particle
is, as we know, given by:
where V is the speed of the particle
and is a quantity hypothetically [
2aVL =
a 4]
given by:
2ma =
where is the mass of the particle.
However, there is no distinction about
the kind of mass (if gravitational
mass, , or inertial mass ) neither
about its sign
m
gm im( )± .
The correlation between and a
α can be established based on the
fact that, on the limit , the
relativistic expression for
∞→c
L must be
reduced to the classic expression
.The result [2aVL = 5] is: cVL 22α= .
Therefore, if mcac =2=α , we obtain
. Now, we must decide if 2aVL =
gmm = or imm = . We will see in this
work that the definition of includes
. Thus, the right option is , i.e.,
gm
im gm
.ma g 2=
Consequently, cmg=α and the
generalized expression for the action
of a free-particle will have the
following form:
( )1∫−= bag dscmS

preceded by the plus sign, cannot
have a minimum. Thus, the integrand
of Eq.(2) must be always positive.
Therefore, if , then necessarily
; if , then . The
possibility of is based on the
well-known equation
0>gm
0>t 0<gm 0<t
0<t
22
0 1 cVtt −±=
of Einstein's Theory.
Thus if the gravitational mass
of a particle is positive, then t is also
positive and, therefore, given by
22
0 1 cVtt −+= . This leads to the
well-known relativistic prediction that
the particle goes to the future, if
. However, if the gravitational
mass of the particle is negative, then
is negative and given by
cV →
t
22
0 1 cVtt −−= . In this case, the
prediction is that the particle goes to
the past, if . Consequently,
is the necessary condition for
the particle to go to the past. Further
on, a correlation between the
gravitational and the inertial masses
will be derived, which contains the
possibility of .
cV →

0<gm
The Lorentz's transforms follow
the same rule for and 0>gm 0<gm ,
i.e., the sign before 221 cV− will be
when and if ( )+ 0>gm ( )− 0<gm .
The momentum, as we know,

we will express the momentum

On the other hand, as we
know, the gravitational force is
conservative. Thus, gravitational
energy, in agreement with the energy
conservation law, can be expressed
by the decrease of the inertial energy,
i.e., ( )14ig EE ΔΔ −=
This equation expresses the fact that
a decrease of gravitational energy
corresponds to an increase of the
inertial energy.
