In the world of physics, it is very difficult to make up an arbitrary theory and hope that it will work for everything. One physical factor is connected to hundreds of other physical events and eventually you will find out that your new theory has too many conflict with the well known physical phenomena that it is simply impossible to arbitrarily manufacture a theory of the nature and make it work. The true theory of the nature has to have the enormous sense of inevitability built into it. Then what makes the theory of dipole gravity inevitable and compelling? For one, it is at the core of general relativity that has been misinterpreted from the beginning.
For an example, when we set up a physical model of an object like a perfect sphere for the calculation of Newtonian gravity, there is no special reason for such a choice other than the ease of calculation of the field and the clarity of the concept that such a choice brings. One can equally have a cubical form of an object for the calculation of the Newtonian gravity. However, getting the accurate field around it in a closed mathematical format will be a nightmarish task and furthermore it serves no purpose in understanding how the force of gravity works in nature.
The serious mistake in the conventional treatment of the gravitational dipole moment in the weak field limit of general relativity was in the mindless choice of the spherical model object which completely obscures the dipole gravity effect. By the choice of the rotating spherical object, the effect of dipole gravity was already thrown out even before one has any chance to calculate it. This mistake can not be put under the rug and this is the main reason I urge Dr. Kip Thorne to revise his text book immediately. He can not continue misleading the innocent young minds especially when he knows of this mistake by many public announcement that I made so far. And I also know many of the readers of this blog have sent him email letters for explanation.
Because if one takes a look at the mechanics of the system more carefully, one can see that the special relativistic mass increase effect distorts the uniformity of the density of the rotating spherical object. So this simple observation should have already hinted the fact that the second order gravity effect of general relativity can not manifest clearly in the spherical model. But this question has never been materialized even though the Lense-Thirring effect provided the crucial hint for the need of such a consideration because it is the clear manifestation of the non-zero second order gravity effect at the center of the rotating spherical mass shell.
The importance of dipole gravity is not actually in its ability to explain the jets or the dark matter problems. It is in the urgency of the mathematical integrity and the physical inevitability that it carries with it. It shows how the equivalence principle brings out the second order effect of general relativity in the form of the magnet like dipole gravity.
Essentially, dipole gravity breaks all the rules of Newtonian mechanics and yet, you can not say it can't be correct because it is at the core of general relativity.
To denounce dipole gravity, you will have to find all the good reasons why general relativity can be wrong which you can't. This is where the compelling reason is outstanding for the experimental testing. But the textbooks on gravitation has to be revised based on the theoretical as well as on the mathematical integrity regardless of the testing, precisely the same way the quadrupole radiation is presented in the text books.
After all, there is no better teacher in science than experimentation.

The Importance of Choice of a Mechanical Model in Physics

Who are Koreans ?
Historically, Koreans tend to distance themselves from the Manchus and the Hyung-nos(Huns) as they were considered nomadic horse riding barbarians who do not know how to discuss the Confucian philosophy using the highly sophisticated Chinese hieroglyphs. It can not be overlooked that Koreans aligned themselves with the Han Chinese as being educated and civilized compared to their more immediate kins of the northern Asia. So you can see there was a great deal of pretentiousness on the part of the so called scholars in the ancient Korean society.
One of the interesting observations in this respect is that Chinese called ancient Koreans "Dong Yi" meaning "The Eastern Tribe riding on a horse carrying a bow and arrows". The Chinese hieroglyphs "Yi" depicts a person riding on a horse with a bow and arrow. So, basically what it means is that the ancient Koreans were also viewed by Chinese as a nomadic horse riding people not much different than Huns(Hyung No) and Manchus, until they settled down in the peninsula to form an agricultural society. In fact, the famous Chinese historian "Sa Ma Chon" wrote in his book "Sa Ki" that Confucius was from "Dong Yi". More specifically it is the area of the present day San dong peninsula which belonged to the proto Koreans in ancient times. When Chin Si Huang Di unified the greater China, Sandong and Manchu were not part of it. Later Sandong people conquered China, expanded its territory and established Han dynasty. The sound Han is the same as that of Hun and Han of ancient Koreans who shared the Tungusic language. The correct sound of Han, Hun is "Kheun" in the present day Korean language which means "Big" and "Great". Obviously, Hun people liked to call their country "great" whenever they built one. So it was Dongyi people who ruled the greater China in Han dynasty. We will see again that Manchus will conquer China and establish Qing dynasty. This is a repeated pattern showing how the historical China has been formed.
At the end of Koryo dynasty, the last King of Koryo ordered his general Yi Sung Gae to attack Manchuria to punish them for destroying Ming dynasty, our beloved Chinese friends. It is the spirit of Koryo dynasty that attracts the special attention. "Orangke" which Koreans called Manchus means savage barbarians.
Sadly, general Yi Sung Gae returned from his post and took the crown and established Chosun(Yi) dynasty. Some may think he was a hero but he was a traitor to his people in a deeper sense. Jeong Mong Ju was the last scholar of Koryo dynasty who opposed general Yi and paid the ultimate price. He was the last honorable scholar of Koryo dynasty who chose the loyalty and principle over the power and wealth. Because he was promised by Yi Sung Gae the greatest role in the new dynasty if he had cooperated. The triumphant spirit of the great Koryo people was ruthlessly mutilated by Yi Sung Gae and his ensuing dynasty, which has wasted most of their time and energy debating on the worthless subject like how many days the sons have to show remorse when their parents or the Kings were deceased, when Japanese were diligently developing the modern technology. The deadly trap of the Confucian philosophy is in the fact that it emphasizes too heavily on how you will be looked at by others in your behavior than how you truly feel inside of yourself. It may be called a philosophy of teaching the most sophisticated pretentiousness in life. But it certainly has its greatest merit which can not be ignored like the strong emphasis on learning. The book of Confucius starts with the saying "Isn't it the most joyful thing to learn and practice every day?" Of course, it depends on what you learn.
Basically, Yi dynasty was fearful of the fact that some military general may revolt and take their dynasty away from them and subsequently neglected in building up the military and technology for the self defense of the nation. Their sins were their worst enemy. As a consequence, Chosun dynasty left the lasting impression of being a timid nation to Japan and China vulnerable to their attacks.
The major reason for this observation that the Manchus and the Huns were more close to Koreans is in the language they use if not the completely identical physical features. The so called Tungstic language which is also called Hunnic language is unique in the sense that the majority of the languages in the world are not like it in terms of the particular grammatical structures. It is known that the Turkish and the Hungarians share the same structure of the language. Unless you have learned any one of these languages, you have no idea how different the Hunnic language is.
The fact that Koreans, Mongols, Japanese, Hungarians and Turkish share this particular kind of the structure of the language is no coincidence. It depicts the trail of the migration and spread of the Hunnic people.
In fact, Manchuria was a greater part of Korean territory in ancient times as admitted by the main stream Chinese history. But it wouldn't be fair to say that Koreans lost that part of the land to China in a war. Instead, in later part of the history, Manchus conquered the mainland of China and separated themselves from the rest of the Koreans and included their land of Manchuria to the rest of the China and established Qing dynasty.
It is not very well publicized fact but it is well worth to note that the Chinese language is more close to Europeans than that of Koreans. It belongs to a part of the so called Indo-European language group. In this particular language group, which is shared by the majority of the languages in the world, the order of the words placed in a sentence is very important while in Tungustic language, they have distinctive sounds that attached to the words specifying if the word is a subject, an object or a verb, which makes the meaning of the sentence very clear even when the order of the words are all shuffled around.
Somehow the Manchurians totally assimilated their grammatical structure of the language into Chinese. But in terms of the pronunciation of the individual Chinese letter system, the Mandarin(standard Chinese spoken language originated from Manchus) pronunciation is more close to that of Koreans than that of Cantonese as one would naturally expect.
As is well known more from the European history, the Huns(Hyungnos)(Chinese built the great wall to protect themselves from the Huns) in the 4th century conquered most part of the Europe and contributed to the ultimate fall of the Rome. The Hunnic people settled down in the modern day great plain field of Budapest Hungary. So, it is not surprising to see that Hungarians speak Hunnic language to this day. The majority of the women Huns brought with them must have settled down there to influence the mother tongue of the whole country. No wonder Europeans have been wondering why Hungarian language is so difficult to learn. The modern day Hungarians do not hide the fact that their ancestors were Huns. Also they are very proud of naming their sons by the name Attila to the chagrin of their heavily Rome influenced neighbors. Still it must be noted that the King Attila the Hun had many children from many of his wives, who inherited his vast conquered Kingdoms in Europe. It is not surprising to see that King Charlemagne is considered one of his descendants.
The historical role of Yamato faction in Japan must also be noted, which is very interesting. Korean history writes that the ancient Baikje kingdom of Korea(south west of the peninsula) had their colony in Japan 1500 years ago. Coincidentally, the last general of Baikje Kingdom, Gae Baik, killed himself like in the Samurai tradition, cutting his own stomach with a sword and killing all of his family(to prevent them from being humiliated by the enemy) upon taking the responsibility of failing to protect his country. The royal family of Baikje kingdom sailed to Japan after the fall of the country by Shilla(south east of the peninsula) and Chinese(Tang dynasty) coalition force. Considering that the written Japanese history starts about this time, it can be concluded that Baikje dynasty was at the core of the unification of the countless Japanese islanders and the establishment of the emperor family which lasted ever since. Most of the core historical tradition of Japanese culture was originated from Baikje kingdom and obviously the Samurai tradition was one of them.
From the far west of Europe to the far east of Japan, Hunnic people left their foot prints and the strongest political and social influences. And of course, those countries have become the major super powers of the modern world. This can hardly be a coincidence.
One may be able to find the deeper root of the meaning of it from the following observation. Nothern Europeans never formed a unified front against Rome before the Hun's invasion of Europe in the 4th century AD. Japanese islanders couldn't be unified before the Yamato faction mobilized by the Baikje kingdom unified them all. Without Baikje's intervention, Japan could have been left pretty much like the modern day Phillipine which doesn't seem to have the core soul of the nation, allowing the constant insurgent of the regional terrorist groups to this day. One can not imagine this kind of disorderly disturbances to happen in any of their islands in Japan.
The Hunnic people in the early history of mankind provided the source of the strong central government to the people of the land they conquered. And they faded away, at least it seemed they did until someone mentions of their monumental achievements. The human civilization could not have flourished without this pivotal central social mechanism. One can own a property only of the size they can visualize and reach. Clearly, the early Hunnic people had the bigger visions of it and the means to reach there.

Frank Tipler's Rotating Cylinder
The rotating cylinder in general relativity poses an interesting mechanical system. It is a system that the researchers in the field considered seriously a time machine may be possible in the strong relativistic regime. Without going into a detailed mathematics, we can visualize what is going to happen in the rotating cylinder within the scope of dipole gravity and tachyonic mechanics. Due to the special relativistic dynamic mass increase effect, the effective gravitational field outside of the rotating cylinder will increase. So, the second order effect from general relativity will be the additional attractive force toward the center of the rotating cylinder.
If the Lense-Thirring force had the right sign, we would have to come to the conclusion that this second order effect of general relativity for a rotating cylinder would have to be outgoing, which isn't. Of course, this is another confirmation that the conventional signs of the Lense-Thirring force can not be correct. Also, there will not be any axial component of the force because the rotating infinite cylinder does not create the shift of the center of mass along the axial direction.
In the tachyonic mechanical point of view, the rotating cylindrical mass disperses and prevents the tachyonic particles from getting inside the cylindrical shell, and consequently creates a relatively higher ether vacuum, which corresponds to the increased gravitational force when viewed from the outside, but reduced inertia on the object inside the shell.
In the extremely strong field regime, when the cylinder rotates in a relativistic frequency, the inertial mass of the object inside the shell will virtually disappear. Therefore, any slight external force will make the object inside the shell to accelerate with a tremendous speed.
The time and the spatial coordinates are entangled in such a way that the motion inside the shell can no longer follow the conventional Newtonian mechanics. But the question on the time machine is a great mystery. Will it be possible to violate the causality? Even if we can travel at the speed greater than the speed of light, after the round trip, we will still be at the later time than we started, once we arrive at the original location, although we may find our friends and relatives are already deceased and we may be looking at their children. I think the key mystery is in the practical length of the cylinder. Since any physically realistic cylinder can not be infinite, there is a point in the middle of the cylinder where the field reverses its direction, or one may call it a discontinuity. Like a rotating spherical shell, the truncated cylinder must have a field reversal point in the middle that corresponds to the center of the rotating spherical shell. And we know there is a tremendously strong potential wall in the middle that doesn't allow the both way stream of the travel in the case of the rotating spherical mass shell. The symmetry is broken due to dipole gravity. To treat this problem rigorously in mathematics, one may have to assume a tiny bulge delta r of the radius near the center of the finite cylinder and let it approach to zero or let the two open ends of the cylinder to be tapered into a point with a lower density material which can be made to approach to zero. In either cases, the result will be a discontinuous field along the direction of the axis of the cylinder.
What this means in reality of the plain English is that the time travel for a physical body is prohibited by general relativity. The known general relativity interpreted by the conventional Princeton-Wheeler group of the school of gravitation was not a complete understanding of the full scope of general relativity which has resulted in the erroneous concept of the time travel by the physical body. I hope the popularists of the Sci-Fi physics realize this fact and stop propagating the time travel of the physical body nonsense. At least we do not have that possibility within the full scope of our known physics.
However, this does not exclude the possibility of the tachyonic particles travel across the channel of the rotating cylinder. The information carried by the tachyonic particles can be transmitted from the future to the past or vice versa, which may hint the fact that the successful predictions of the short or the long term future, commonly known as the prophecy may be possible.

Report of the Recent Development
Email letter from Dr. Herbert Pfister upon the Request of Copy of his Paper “On the History of the So-Called Lense-Thirring effect”.
Dear Dr. Jeong,
In the attachment you receive my paper on the history of the so-called
Lense-Thirring effect, as published in General Relativity and Gravitation.
I have also talked about this topic at the Erice Summer School (in honour
of John Wheeler) in June 2006, whose Proceedings should appear soon at
Springer. In 3 weeks from now there will be a conference "Beyond Einstein"
in Mainz, where I again will speak about this, and about more recent
extensions (quasiglobal principle of equivalence, cosmological aspects of
dragging). These conference proceedings should later appear as a volume in
the Einstein Studies at Birkhaeuser.
Concerning the papers you attached to your mail, I should say that I
disagree with most of your arguments. I may disclose (after more than 10
years) that I have been referee for your papers submitted in 1996/97 to
Phys.Rev.Lett. and Class.Quant.Grav.. So you know most of my
counter-arguments, i.e. the coordinate dependence of your dipole moment
results. From this time I also know that other referees had similarly
negative arguments.
In contrast, my "solution of the centrifugal force problem" in
Class.Quant.Grav. 2(1985)909, and in my article in the book "Mach's Principle"
(Tuebingen Conference, ed. by J.Barbour and H.Pfister, 1995) is approved by
most experts in the field (C.Will, K.Nordtvedt, J.Ehlers, W.Bonnor, D.Brill,
I.Ciufolini, W.Rindler et al.).
I am sorry that my opinion of your work is not more positive. (I have not
read your attached articles in detail because their content seems to be
very similar to the articles, I rejected in my function as referee.)
Sincerely,
Herbert Pfister
Response by E. Jeong
Dear Dr. Pfister,
I appreciate your email and the attached file. After reading your paper, one
question that I may have is, at some point, all the calculations have to be
based on a certain coordinate system to make any sense out of the general
covariant formulation. I think the linearized theory of general relativity
is one of such attempts where the theory of dipole gravity is based. At
least it succeeded in reproducing the Newtonian gravity.
Regarding your statement, "any physically realistic, rotating object will
suffer physical deformation, in orders omega^2 and higher". I agree with
your point that there will be a deformation due to the centrifugal force.
But is it possible to exactly quantify the degree of deformation?
I think the rigidity of the matter is a relative concept. Most importantly,
depending on the tensile strength of the material, the degree of deformation
will differ by a vast magnitude. If we assume that there is a thin spherical
mass shell of the black hole density, it won't deform until it reaches the
rotation at the surface very close to the speed of light. So, to my humble
opinion, it is possible to postulate that the rigidity of the matter can be
assumed to the highest level without the loss of generality. In fact, the
formulation of dipole gravity didn't require the fast rotation of the
spherical shell, because the shift of the center of mass starts from the
point zero. We only have to assume that the material is strong enough to
withstand the given rotational speed without deformation. In fact, the
general deformation will be certainly destructive in such a way that the
shell no longer can be considered spherical or any known form, if it is
possible, beyond a certain rotational speed.
I think dipole gravity transcends general relativity. The cosmological
evidences for its existence are overwhelming. Please remember that we had
Newtonian gravity before we knew there is general relativity. I tend to
think that if general relativity is really a correct theory of the universe,
it should have predicted the presence of dipole gravity as it did. But
dipole gravity can also exist without general relativity as a separate
entity. In my opinion, general relativity only facilitated the hint on the
presence of dipole gravity in a cryptic way.
Sincerely,
Eue J Jeong
Email Response from Herbert Pfister,
Dear Dr. Jeong,
Concerning the deformation of my shell, I should say the following:
a) The shell is deformed in a prolate form, and this is an invariant
result, because I have calculated the invariant equatorial and polar
circumferences. In the collapse limit the form becomes spherical,
as already proven by de la Cruz, Israel (my ref. 15).
b) However, my shell does not consist of "normal material" which you can
order in a workshop. The shell was defined by the (non-material) condition
that its interior is flat, in order to fulfil Mach's demand for
"relativity of rotation" (correct Coriolis and centrifugal forces in its
interior).
Concerning your "dipole gravity", I may repeat that in GR a dipole moment
of an isolated system is a coordinate dependent statement (you can always
make the dipole moment zero by transforming to an appropriate coordinate
system). If you go beyond GR, this statement is of course no more true.
However, to go beyond GR, you have to have very strong arguments which I
do not share: GR is, on one hand, experimentally tested in so many
different regions, and in some of them with very high precision. On the
other hand, GR has overwhelming inner consistencies which rival theories
usually do not have. E.g.: equations of motion follow from the field
equations; positive energy theorem (GR is the only theory which allows to
fix the zero of energy, in contrast e.g. to Kaluza-Klein-theories, as I
could prove with Dieter Brill in Phys.Lett. B228(1989)359).
Sincerely,
H. Pfister
Email Response from E. Jeong,
Dear Dr. Pfister,
It seems to me you decided to cut the legs and arms of a child to make
him/her fit into an old cloth. General relativity is a brand new theory,
very sophisticated, diverse, correct and full of potential and surprise. I
don't know why anyone would want to impose a flatness condition on inside a
rotating shell to make it fit the old Machian demand for "relativity of
rotation". Basically, you artificially imposed an old condition to get the
desired solution you intended. So, in the process, no new knowledge is
gained.
Also, your statement "any physically realistic rotating body" in your paper
seems to contradict the next statement in your email, "my shell does not
consist of "normal material" which you can order in a workshop". I think
"any physically realistic material" should be considered "a normal
material". But I don't know if you can consider a neutron star as composed
of a normal material. For a cosmological consideration, I would consider
neutron star as consists of a normal matter which would be the most rigid
known material in the universe next to the black hole.
The kinetic energy which is equivalent to mass obviously increases in a
rotating mass shell. The farther from the axis of the rotation of the mass
component, the more increase of the mass. So, a rotating hemisphere develops
a dynamic shift of the center of mass while this can not be said to be true
for a rotating spherical mass shell. Is this phenomenon coordinate
dependent? If it does, what makes the rotating hemisphere different from the
rotating sphere? If we use the same coordinate transformation to make the
shift to disappear for the rotating hemisphere, it will reappear for the
rotating sphere, whatever the transformation may be.
I already discussed this problem in 1995 with Dr. Kip Thorne of Caltech, one
of the authors of the book "Gravitation", and he said "the concept of the
gravitational dipole moment makes sense...." after a lengthy debate over the
email. But I don't think I need his confirmation to know this observation is
correct.
Since the spin rotation is a separate degree of freedom of motion relative
to the linear motion, this phenomenon of the relativistic center of mass
shift for a rotating hemisphere represents a very unusual mechanical system.
It violates Newtonian mechanics straight on because you can displace an
object just by rotating it by giving it a slight impulse on the rim
perpendicular to the direction of the linear displacement. But the key
reason for the violation is special relativity, not general relativity. In a
way, general relativity clarified its property by identifying it as the
major second order term(diagonal) in the linearized theory. So we have
dipole gravity.
The simplicity of explaining the jets and the dark matter problem at the
same time using dipole gravity will be the most spectacular success of the
theory. No other theory has shown such a feat.
Plasma and magnetic field theory proposed by Blanford "explained" jets but
not the dark matter problem, on the other hand, Mondian cosmology explained
the dark matter problem but not the jets. But I always knew instinctively
that there must be a purely mechanical theory for both of the problems since
I was a graduate student at the University of Michigan, Ann Arbor.
It basically fulfilled the dream of general relativity, as it supposed to
be. That is, the problems in the large scale universe can be explained by
general relativity. However, until 2007, I didn't notice the sign error in
the Lense-Thirring force and it impeded the explanation of the dark matter
problem. But then suddenly there came the Copernican change of the view,
what if the signs of the Lense-Thirring force were reversed?
Instantly, everything became crystal clear. The attractive radial component
of the Lense-Thirring force is only a tiny manifestation of the (medium) long
range attractive dipole gravity force and the repulsive axial component of the
Lense-Thirring force is at the core of the driving force of the jets in both
directions of the poles. The dark matter halo is a matter distribution due
to this dipole gravity force lines all around the rotating neutron stars and
the black holes. You may recall that the astronomers observed jets from the
neutron star where people do not expect the plasma will be present and the
neutron stars do not have the horizon. The theory of the jets proposed by
Blanford et al already started to crumble.
We can insist the Mach's view inside of the rotating mass shell and forget
about the jets and the dark matter problems, but if we change our
perspective and open our eyes, we can see the grandeur beauty of general
relativity, the beauty that Einstein would have loved to see in his life
time.
Sincerely,
Eue J Jeong
I havn't received response since Sept 4 2008.
I still think Herbert Pfister's book is an excellent reading for a complete historical review of the Mach's principle and the Lense-Thirring force before dipole gravity. Of course, his book is a living proof of how badly we have been lost in the mystery of the Lense-Thirring effect. The detailed rendition of the discussions on the subject by the numerous prominent gravitational physicists with Dr. Pfister is truly a fascinating reading.

Academic Professional's Misconduct
The following is a part of the article in the handbook related to the academic professionals misconduct in research and searching for the truth and I found it alarming yet very interesting.
"A climate must be maintained at the University where creativity and productivity in research are promoted in an atmosphere of high ethical standards. It is essential that the integrity of research be maintained at all times, since long-standing, often irreversible damage can result from breach of academic commitment to truth in investigative activities. Misconduct in research is herein defined as gross lack of integrity in conducting basic or clinical investigations involving dishonesty, knowing misrepresentation of data, and/or violation of accepted standards. Academic misconduct or fraud can destroy public trust in the academic community as a whole and in our own institution in particular; it can shatter individual careers; it can undermine sensitive relationships between investigators, students, and the public.
In modern collaborative research, the implications of academic misconduct or fraud go far beyond the individual; they also affect collaborators whose own work has been committed to objective search for truth. The specter of guilt by association may lurk in the background for many years to come. Therefore, joint authorship requires joint responsibility; each author claiming credit for the entire work must also be aware of joint discredit. Investigators in collaborative research projects each must make reasonable and periodic inquiry as to the integrity of and processes involved in gathering and evaluating data. It should be understood that overall responsibility for the integrity of collaborative research rests with the principal investigator. Senior investigators cannot be allowed to escape the consequences of the discovery of misconduct or fraud committed under their supervision."
Regarding the professionals at the institutions of teaching the theory of gravity, I wonder how can they teach their students without having a guilty conscience that the gravitational dipole moment doesn't exist after being informed of the theory of dipole gravity. It will take a second to realize that there is a serious mistake in the books of gravitation. They should know they are lying when they teach that faulty concept in their classes. The excuse of an honest mistake, or having not been informed, no longer applies here. I think it is basically the same as academic cheating, because it is an act of knowingly misleading the students. Is this the way the scientists of today should conduct in the University where we expect the people to have the highest ethical standard?
I'm interested in the widest dissemination of the important scientific truth for the benefit of mankind. If it requires to dragging em into the court for the criminal academic misconduct, although I sincerely hope it doesn't have to go that far, I may have to consider it as an option.

Conservation Law of Energy
Although, according to Noether’s theorem, the time translation symmetry of the Lagrangian is directly related to the conservation of energy of the system, the crucial point of the importance of the energy conservation is what is the range that the law specifically covers? Does it cover the entire universe or only the local system?
To elaborate the point of the argument, here is a suggested Gedanken experiment. For an example, suppose there is a test mass in a thermally isolated container. One decided to influence the energy of the test mass inside the container from outside and moved a heavy mass back and forth to change the gravitational force on the test mass. Following the external influence, the test mass initially set at rest started to oscillate and gained a definite kinetic energy delta E.
Of course, one will argue that the applicable range of the total energy of the system has to be extended beyond the closed container where the test mass is located. But suppose that the heavy mass outside of the container is located so far away from the test mass that the existence of the heavy mass’ external influence is not verifiable. Now one can see that the boundary of the local conservation of the energy law has to be stretched to the infinity which is the practical range of the force of gravity.
Therefore, in general, it can be stated that the local conservation of the energy law can not be respected for the long range forces. One can always try to reformulate and enforce the law but when the boundary is infinite, what is the purpose of such an enforcement? There are always possibilities that one can devise a system that the local energy is practically gained at the expense of the energy loss from somewhere else in the universe.
The mentioned influence of the external force can be initiated by manipulating the specific local configuration of the test mass, for example, by the rotation of the longitudinally asymmetric object which produces the dipole gavity effect.
After all, general relativity and Maxwell’s equation are the theories describing how the matters are interacting with each other within their own principles of interactions in the universe, and they are not about acting like a watchdog for the local conservation of the energy. The inherent nature of the long rangedness (infinity) of those forces makes the local conservation of the energy within these principles meaningless.
However, the strong force which is extermely short ranged and holds the nucleus together and also subsequently the atoms and molecules will definitely conserve the local energy as proven to be correct abundantly in the kinetic theory of gases.

Possibility of Non Existing Gravitational Waves
The fundamental postulate of general relativity is that one can not tell the difference between the gravitational field and the uniform acceleration, which is called the equivalence principle. So according to this postulate, the gravitational field is basically the same as the source of the acceleration of the matter itself. Now, for there to be a gravitational wave, this acceleration field must be disturbed in such a way that it changes its magnitude depending on time. However, in general mechanics, the time derivative of an acceleration is not defined. That is to say, there is no da/dt, which is the time derivative of an acceleration.
If the gravitational waves were found, it means that the general equation of motion can be a third order differential equation instead of being a second order one. It breaks down the fundamental principle of Newtonian mechanics in a strange way since there is no such thing as the rate of change of the acceleration defined in the Newtonian laws of the mechanics. But then so was dipole gravity, in a different way, since an object can be physically displaced without the external force in the direction of the displacement, which occurs in the rotating hemispherical objects.
And without the detailed investigation of this effect, it was easy to dismiss dipole gravity as non existent physical entity from the start. Now with the gravitational quadrupole radiation, no one seems to pay attention on how it may violate Newtonian mechanics and the equivalence principle. For the sake of fairness, it is far more imperative to investigate dipole gravity experimentally. It won't be too late to test the quadrupole radiation effect later.
While an electric charge in circular motion around a positively charged ion loses energy by electromagnetic radiation, although the electron keeps its stable orbit around the proton due to the quantum effect, the satellite matters orbiting around the heavy condensed stars do not lose energy by radiation. Therefore, the constantly accelerating mass due to its circular motion around a host stellar object does not produce the gravitational waves.
This is the fundamental physical difference between the electrodynamics and the gravity. If the gravity is the same as the acceleration field of an object, the gravitational radiation must be a time derivative of the acceleration field itself, which is not defined in mechanics, although, this point may need more serious debate.
The energy loss observed from the fast rotating binary stars has been considered an evidence of the gravitational radiation. However, the space debris that being attracted by the two mass pole star system will see the center of mass of the two stars as the focal point of the gravitational attraction when viewed from the far distances. The impact of the debris with the two massive stars will be perpendicular to the rotational motion of the individual stars. This will create enough losses of the angular momentum and could account for the major energy loss. Therefore, this observation can not be considered an ultimate proof of the existence of the gravitational waves.
What it fundamentally suggests is that the gravitational wave may be harder to produce than one would imagine, if not impossible.
One possible application of dipole gravity may be that one can easily change the geometrical configuration of the rotating hemispherical object by using many layers of independently rotating discs or rings. This can be made to produce a longitudinal(directional) dipole gravity pulses like a pulsating beam of light which can be used to remotely pull or push objects where the pulsed dipole gravity beam may be pointed at.
Still, in this case, the pulsating beam of a directional dipole gravity is fundamentally different from the quadrupole gravitational radiation typically understood in the field of gravitation and general relativity.
