"The Matter of"Dark Matter"
(See also our sister website reticsessays.com)
There have been many postings about the mysterious "Dark Matter" which
is alleged to constitute 90 to 95% of the mass(energy) content of the
Universe. The presence of this "Dark Matter" is indicated by the observed
gravitational behavior of galaxies and clusters of galaxies. A large effort
is apparently underway to detect this "Dark Matter" and to determine its
nature. In all of the discussions there seems to be little attention to the
3 - 3.5 degree K background radiation known for decades to be present. If
one examined the energy represented by this radiation, he finds that it is
10 to 20 times the energy represented by the mass of conventional matter.
Obviously, however, there is no need to pay attention to this radiation
because, as everyone knows, electromagnetic radiation does not possess
inertial or gravitational mass.
Since everyone "knows" that electromagnetic radiation does not possess
inertial or gravitational mass, it behooves us to examine the validity of
that belief. It has long been known that electromagnetic radiation
transports momentum as witnessed by the pressure of Solar radiation which
causes comets to have "tails". In addition, mainstream physicists have
discussed the feasibility of using "light sails" for the propulsion of long
distance space ships. Mainstream physics tells us that the momentum
transported by a photon is identical to the momentum which would be
transported by a material particle of the same total energy (rest mass plus
kinetic energy). - I know that the rest mass of a material particle
traveling at the velocity of light must be zero. But lets not quibble,
divide that zero by the zero represented by the Lorentz Transformation for
mass and the inertial mass of the material particle can have any value
between the limits of +/- infinity. Since momentum is equal to the product
of inertial mass and velocity, and the momentum of a photon is given by its
energy divided by the velocity of light, then dividing the equation which
provides the momentum of a photon by C shows that the photon behaves as if
its inertial mass were equal to its energy divided by the square of the
velocity of light. Maybe photons do not possess inertial mass in spite of
observation, but as far as the writer is concerned, if it looks like a duck,
walks like a duck, and quacks like a duck, he is willing to accept that it
is a duck. The inertial mass of photons meet this test and if the current
state of physical knowledge teaches otherwise it is time for physicists to
rethink the subject.
Since photons act as if they possess inertial mass traveling at the
velocity of light, the background radiation of space must exert a pressure
which acting to cause the Universe to attempt to expand. Let us examine
whether those same photons possess a gravitational mass. This is best done
by considering an ideal thought experiment along the lines of those used by
Dr. Einstein. Consider a cold gravitationally massive planet in
intergalactic space (to eliminate spurious disturbances). Attached to
opposite sides of this planet are infinitely rigid and massless columns each
of which support an ideal retro reflector having 100% efficiency. (I know
that these assumptions are physically unrealizable but that does not
interfere with there use in this though experimant.) A beam of photons is
sent from one of the retroreflectors, is bent by the planet's gravitational
field as required by General Relativity, and strikes the retroreflector on
the other side of the planet. Because these are ideal retroreflectors, the
photons are constrained to continuously travel bask and forth past the
planets surface. It is a simple calculation (not involving relativity) to
show that as a result of the gravitational "refraction" of the photon's path
the process will cause a net force to be exerted on the retroreflectors in a
direction which is "down" at the point where the photons pass the surface.
If we are to accept that the "Laws of Conservation of Energy and Momentum"
are valid, then there must be an upward pull on the planet equal to the
downward push on the retroreflectors. If these two forces are not equal, the
entire system could be used as a "space tug" in violation of Newton's Second
Law and/or a source of limitless energy in violation of the First Law of
Thermodynamics. The thought experiment is diagrammed below. Its validity
does not depend upon relativistic considerations. This thought experiment
shows that, if light is observed to be "refracted" by a gravitational field,
that "refraction" must result not from the 'curvature" of space but from a
gravitational force. The magnitude of that force must result from the
photons having a "gravitational mass" equal to twice their inertial mass.
For a more detained discussion see paragraphs 8.8 and 8.9 of
http://einsteinhoax.com/hoax.htm and http://einsteinhoax.com/gf421.gif.
When one combines the effects of the gravitational and inertial
"masses" the photons which are observed to propagate through our Universe
one finds that the inertial mass tends to act as a gas to expand the
Universe while the gravitational mass acts like any other gravitational mass
and acts to contract the Universe. The size of the Universe at any one time
is determined primarily by the balance between these two effects. Once the
"big bang" state had been reached, the pressure of photons acted to produce
the observed expansion which will go on forever. All of these conclusions
are derived and discussed in http://einsteinhoax.com.

TRUE, IT MUST BE CONSISTENT WITH ALL OBSERVATIONS, AND IT MUST BE
MATHEMATICALLY VIABLE. PRESENT TEACHINGS DO NOT ALWAYS MEET THIS
REQUIREMENT. THE WORLD IS ENTITLED TO A HIGHER STANDARD OF WORKMANSHIP FROM
THOSE IT HAS GRANTED WORLD CLASS STATUS.
