6 pages, 1 figure. Set of notes being turned into an article as to inter
relating a graviton count, versus gravitational waves. Will be part of discussions
raised in conferences this summer.
coming up with specifics as far as the inter relationship
The following questions are raised. First, can there be a stable (massive) graviton? Secondly, what
is the relationship between a Gravity Wave, and Gravitons? The inter relationship between a graviton,
and a gravity wave is raised, with an idea of eventually making sense of a numerical count presented
by Claus Kieffer, in his book on Quantum gravity, in conjunction with how a gravity wave/ graviton
count could have some over lap.

The theory of gravitoelectromagnetism (G.E.M.) - that assumes a perfect isomorphism
between electromagnetism and gravitation - has been established by Oliver Heaviside (1) and
Oleg Jefimenko (2). Within the framework of general relativity, G.E.M. has been discussed by
a number of authors (3). It is shown that the gravitational analogs to Maxwell's equations (the
G.E.M. equations) can be derived from the Einstein field equation.
In this paper we propose an alternative theoretical foundation of G.E.M.: we explain the
gravitational interactions, we identify the physical quantities that play a role in that context,
and we mathematically derive the laws of gravitoelectromagnetism .

Comments: 28 Pages. This work develops the Natario Warp Drive from ther arXiv paper gr-qc/0110086.
Natario Warp Drive is one of the most exciting Spacetimes of General Relativity.It was the second
Spacetime Metric able to develop Superluminal Velocities.However in the literature about Warp Drives
the Natario Spacetime is only marginally quoted. Almost all the available literature covers the Alcubierre
Warp Drive. It is our intention to present here the fully developed Natario Warp Drive Spacetime and
its very interesting features.Our presentation is given in a more accessible mathematical formalism
following the style of the current Warp Drive literature destined to graduate students of physics since
the original Natario Warp Drive paper of 2001 was presented in a sophisticated mathematical formalism
not accessible to average students. Like the Alcubierre Warp Drive Spaceime that requires a continuous
function f(rs) in order to be completely analyzed or described we introduce here the Natario Shape
Function n(r) that allows ourselves to study the amazing physical features of the Natario Warp Drive.
The non-existence of a continuous Shape Function for the Natario Warp Drive in the original 2001 work
was the reason why Natario Warp Drive was not covered by the standard literature in the same degree of
coverage dedicated to the Alcubierre Warp Drive. We hope to change the situation because the Natario
Warp Drive looks very promising.

6 pages, no figures. Part of accepted contribution to the Frontiers of
Fundamental physics 11 conference, Paris, as a poster. Will be part of questions
raised in documentation for the DICE 2010 conference in Italy run by Thomas Elze,
September 13-17, 2010
This document is due to a question asked in the Dark Side of the Universe conference, 2010, in
Leon, Mexico, when a researcher from India asked the author about how to obtain a stability analysis
of massive gravitons. The answer to this question involves an extension of the usual Pauli_Fiertz
Langrangian , with non zero graviton mass contributing to a relationship between the trace of a re
done GR stress-energy tensor ( assuming non zero graviton mass) , and the trace of a re done
symmetric tensor , times a tiny mass for a 4 dimensional graviton. The resulting analysis makes use
of Visser's treatment of a stress energy tensor, with experimental applications discussed in the
resulting analysis. If the square of frequency of a massive graviton is real valued and greater than
zero, stability can be possibly confirmed experimentally.

Very often, in the history of science, amazingly simple phenomena, when initially
misunderstood, may become laden with prejudice and somewhat mystical connotations and,
since then, are passed on from generation to generation for no better reason then magister
dixit. One example already discussed here [1] has been stellar aberration. But there is
nevertheless a very special case where in trying to explain the null result of the Michelson and
Morley experiment scientists, just to keep up to their prejudices, chose the weirdest
explanations; instrument length contraction or Ether drag !

Clocks are measuring systems for the numerical order, speed and frequency of material
changes that run into space. Time does not run into space on its own, time exists only as
numerical order, speed and frequency of material change. Stellar objects and particles move into
space only and not into time. Gravitational interaction between material objects is the result of
curvature of space that is determined by the granular structure of space. Density of the elementary
grains of space depends on density of universal cosmic mass, higher is the density of universal
cosmic mass lower is the density of grains of empty space. Density of empty space is the physical
basis of its curvature. Material objects have a tendency to move into direction of lower density and
higher curvature of space. Gravitational interaction mass-space-mass is immediate: the presence
of a mass causes change of density of space, change of density of space causes gravitational
motion. A mass acts on another mass indirectly via the change of density of empty space.
Gravitational interaction between two masses is immediate: no time, namely no duration of motion
of a particle or wave in space is needed to transmit gravitational interaction from one to another
material object.

With clocks we measure numerical order t0,t1,t2,...,tn of a physical event. A sequence tn-1 is
"before" a sequence tn equivalently to natural number n-1 is before natural number n.
Numerical order t0,t1,t2,...,tn of a physical event has no duration. It runs in a timeless space
where physical time is run of clocks. Duration of an event is a result of experiencing its
measurement with a clock through the frame of psychological time "past-present-future" but
events happen exclusively in space.

For several physical phenomena elapsed clock run t for them to happen is zero. These
events can be appropriately defined as "immediate physical phenomena" and support the
view that, at a fundamental level, time exists only as a run of clocks in a timeless space.
Immediate physical phenomena are carried directly by space which functions as a direct
information medium. The perspective is opened that the quanta of space that build quantum
space assume a crucial role as regards these phenomena.

Rotating the source of light around the point lying on the light's beam we can observe the
transverse Doppler effect by a spectrometer located in the center of rotation. The anomalous shift of the
electromagnetic wave's frequency was found from this experiment (performed in 1969-1974 years)
that appeared to be much higher than anticipated from the standard relativistic expression taking
into account solely the linear velocity of rotation of the source in the laboratory. The interpretation
of the experimental observations admitting absolute motion of the Earth and respective accounting
for reality of the Lorentz contraction and time dilation enabled us to determine the speed of the
Earth relative to luminiferous aether. It appeared to be somewhat above 400 km/s that agrees well
with the value formerly found by me using three methods of determining the speed of "aether wind"
by Michelson-type interferometers thoroughly accounted for refractive indices of optical media.
