İzmir Kemalpaşa Muhtarı 1944 doğumlu Yumrutaş lı Bekir amcanın ağzından Hüseyin YILMAZ
Hüseyin Yılmaz ı köyümüzün büyüklerinden dinlediğin kadarıyla tanırım. Küçük yaşlarda babasını kaybeder. Bir ablası evlidir. Bunlar 3 çocuk ortada kalırlar. Fakirdirler. Köylüler bakar. O zamanlar ilkokul üçüncü sınıfa kadar okunurmuş. Okulunu bitirir. Perşembe günleri Bedirbey ile bizim köyün arasındaki ovada işken pazarı kurulurmuş. Bir gün bu pazara Denizlide un fabrikası olan zengin iş adamı Kaşıkçılar gelmiş. Büyük miktarda buğday almış. Hesabın içinden çıkamamışlar. Bu çocuk ben yaparım demiş ve kısa zamanda hesabı çıkarmış. Kaşıkçı bu çocuğa hayran kalmış. Sormuş soruşturmuş fakir olduğunu öğrenmiş ve okutmak için denizli ye götürmüşler. Hüseyin Yılmazın hayatı böylece değişmiş. 17.02.2005

Yilmaz theory of gravitation
From Wikipedia, the free encyclopedia
The Yilmaz theory of gravitation is an attempt by Huseyin Yilmaz and a handful of coworkers to formulate a classical field theory of gravitation which closely mimics general relativity in weak-field conditions, but in which event horizons cannot appear.
(Orthographic caveat: in Turkish, Yilmaz's name is properly written Hüseyin Yılmaz; we will avoid this spelling because English-speaking readers are likely to misread the ı as i, which could cause technical difficulties. The spelling we use is the one Yilmaz adopts in the arXiv.)
Yilmaz's work has been sharply criticized on various grounds, including the claims that
· his proposed field equation is ill-defined,
· the two desiderata above are incompatible (event horizons can occur in weak field situations according to gtr, in the case of a supermassive black hole).
Yilmaz vigorously disputes these criticisms. Nonetheless, apart from Yilmaz's own papers, the theory has apparently received no attention in the research literature, apart from two critical papers. Yilmaz claims that his critics have misunderstood him, but it has been suggested that his papers are too murky in crucial places to admit a single clear interpretation. Yilmaz's credibility has also been badly damaged by what appear to be serious misstatements about general relativity.
It is well known that naive attempts to quantize general relativity along the same lines which lead from Maxwell's classical field theory of electromagnetism to quantum electrodynamics fail, and that it has proven very difficult to construct a theory of quantum gravity which goes over to general relativity in an appropriate limit. Yilmaz has claimed that, in contrast, his theory is in some sense 'compatible with quantum mechanics'. He even suggests that it might be an alternative to superstring theory. These claims have apparently been given no credence by physicists other than Yilmaz and a handful of his coworkers.
Yilmaz has offered several descriptions of the alleged field equation for his 'theory', which his critics feel are neither entirely consistent with each other nor well-defined. To understand one of the most basic criticisms of Yilmaz's work, one needs to be familiar with
· the statement of the Einstein field equation,
· the distinction between coordinate dependent and coordinate independent quantities,
· well known facts concerning integration in curved spacetimes,
· well known facts concerning gravitational energy-momentum pseudotensors in general relativity.
With this background in hand, one can say that Yilmaz apparently wishes to keep the left hand side of the Einstein field equation (namely the Einstein tensor, which is well defined for any Lorentzian manifold, independent of general relativity) but to modify the right hand side, the stress-energy tensor, by adding a kind of gravitational contribution. According to Yilmaz's critics, this additional term is not well-defined, and cannot be made well defined.
Yilmaz has apparently failed to produce a convincing proposal for an observational or experimental test of his theory, and it would appear that no astronomers have contemplated any attempts to test his ideas. On the other hand, astronomers are very interested indeed in testing theoretically solid competitors of general relativity; see Category:Tests of general relativity.
YILMAZ GENERAL RELATİVİTY (YGR)
Hüseyin Yilmaz (1958, 1982) modified Einstein's theory of general
relativity (EGR) to include a gravitational stress-energy tensor that
eliminates Einsteinian black holes altogether. To my knowledge it is the
only general relativistic theory that does not have a black hole horizon,
and is of interest for that reason. For all the major tests of EGR, the
advance of the perihelion of mercury, gravitational red shift, and the
bending of starlight (the least accurately measured of the three tests)
which have been done at moderate fields, Yilmaz general relativity (YGR)
gives essentially the same predictions as EGR, because it differs mainly for
large gravitational fields. It removes so many difficulties and paradoxes
that it deserves to be considered even if it is contrary to some people's
sensibilities. YGR has evolved with time from his 1958 paper to his papers
in the 1970's. The main question is one of consistency with nature, not one
of theoretical consistency since even EGR may have some inconsistencies
such as in allowing the existence of singularities, and in the interchange of
space and time coordinates inside a black hole.
For now let us only compare the success of the theoretical
predictions of EGR and YGR with experimental observations, without
consideration of internal consistency. This is the spirit in which the
Schroedinger equation has long been judged. The Schroedinger equation
works remarkably better than it should in giving highly accurate
predictions of the energy levels of the hydrogen atom -- the archetype
An understanding of the Einstein General theory of Relativity is an essential requirement for one to explore the creation of our universe. Although the equations of General Relativity are very complicated, the books explain the principles of this theory in a simple manner. The books also give a simple explanation of the Yilmaz theory.
To introduce the Einstein and Yilmaz theories, the books explain Newton's theory of gravity. The key to the development of Newton's theory was Newton's invention of calculus. Newton applied calculus to principles discovered by Kepler and Galileo, and thereby derived his laws of mechanics. Newton showed that his laws of mechanics exactly satisfied Kepler's laws of planetary orbits, and accurately described the orbit of the moon around the earth.
Einstein's basic (or Special) theory of Relativity was developed to explain an enigma associated with the speed of light. The books describe the principles of light propagation, and show how confusion evolved when scientists attempted to measure the speed of light. To what reference is the speed of light measured? Is it measured relative to the body that emits the light, is it measured relative to the body that receives the light, or is it measured relative to a mysterious medium, called the aether, relative to which the light presumably moves?
Einstein concluded that absolute velocity has no meaning, and so there cannot be an aether medium that establishes an absolute reference for the speed of light. We can only consider relative velocity. Consequently two observers moving at constant velocity must measure exactly the same value for the speed of light, regardless of the velocity between them. In order for this principle to hold, Einstein concluded that measurements of distance and time must be relative. For example, the length of an object is not absolute; it varies with the velocity of the observer that is measuring the object. Distance and time measurements are Relative. Reality is Relative.
From the Relativity principle presented in 1905, Einstein derived several profound conclusions. One of these was that matter can be converted into energy. Each gram of matter converted into energy releases 25 million kilowatt-hours of energy. This principle explained the source of the enormous energy radiated by our sun, and eventually led to the awesome might of the atomic and hydrogen bombs.
Einstein soon discovered that his theory of Relativity applies exactly only for observers moving at constant velocity. It does not apply exactly when the velocity changes, which means that an observer is accelerating. He showed that acceleration and gravity are equivalent, and therefore his basic Relativity theory does not apply exactly in a gravitational field.
Einstein spent 11 years of intense research to generalize his theory, so that it could account for the effects of acceleration and gravity. He published his General theory of Relativity in 1916. After that, his basic 1905 theory became known as the Special theory of Relativity.
The Einstein General theory of Relativity applied the complicated mathematics of curved space developed by the German mathematician Bernhardt Riemann and the Italian mathematician Gregorio Ricci. Because of the complexity of this mathematics, a myth evolved that only an elite band of geniuses could understand General Relativity. This book explodes that myth, to show that General Relativity principles can be readily comprehended by the average reader.
Since General Relativity is a theory of gravity, it has been used as the foundation for studying gravitational effects in our universe. Einstein specified General Relativity by his gravitational field equation. This is a complicated tensor formula, which represents 10 independent equations. This formula can be applied analytically only to very simple physical models; otherwise it yields millions of terms. It was not until the mid 1960's, a decade after Einstein's death, that computers allowed the Einstein formula to be applied to complex physical models. Since then, many hundreds of scientists have devoted their careers to computer studies of General Relativity.
In the 1950's Huseyin Yilmaz was studying General Relativity as part of his PhD research at the Massachusetts Institute of Technology. He examined an approximate calculation that Einstein had made in developing General Relativity and discovered that he could solve it exactly. This yielded an exact solution to the principles of General Relativity and resulted in the Yilmaz theory of gravity. Yilmaz mailed his analysis to Einstein, but Einstein died in 1955 before he could read it. Yilmaz published his gravitational theory in the prestigious Physical Review in 1958.
The Einstein gravitational field equation was developed by Einstein in an intuitive manner, after many years of searching for a solution to his Relativity principles. Tests were performed to validate the Einstein formula, and it appeared to work. However, the great mathematical complexity of this formula has obscured the fact that it is not a rigorous solution to the principles of Relativity. The limitations of this formula have became apparent after Einstein's death. The singularity predictions of modern Big Bang cosmologists are symptoms of the fact that the Einstein gravitational field equation is not rigorous.
Yilmaz derived a different gravitational field equation. Although Einstein developed his gravitational field equation in an intuitive manner, Yilmaz derived his equation from rigorous analysis. Since the Yilmaz theory has applied the principles of General Relativity, it is a refinement of the Einstein theory. With rigorous analysis, Yilmaz has proven that the basic principles of General Relativity are inconsistent with singularities.
Application of Einstein and Yilmaz Theories
The book applies the Einstein and Yilmaz theories to a star, which could be our sun, to show the relativistic effects produced gravity. Gravity causes the speed of light to decrease, a spatial dimension to contract, and a clock to run slower. The Einstein results are based on the solution to General Relativity developed by Karl Schwartzschild in 1916. Unfortunately Karl Schwartzschild died suddenly from disease even before his famous solution was printed.
The plots show that the Einstein theory has a limit, called the Schwartzschild limit, which occurs when the ratio of mass to radius of a star is 240,000 times greater than the ratio for our sun. The Schwartzschild analysis does not yield a solution above this limit. At the Schwartzschild limit, the speed of light goes to zero.
In 1939, Robert Oppenheimer (who later directed the Manhattan atomic bomb project), along with his graduate student, Hartland Snyder, showed in a technical paper that the Einstein theory can yield a solution when the Schwartzschild limit is exceeded, if one assumes that the star contracts continuously.  This led to the conclusion that when the mass-to-radius ratio of a star exceeds the Schwartzschild limit, the star must "contract indefinitely" until it shrinks into a singularity. The star is theoretically surrounded by a spherical surface, called the event horizon, over which the speed of light is zero. Light theoretically cannot escape from within the event horizon, and so the star was called a "black hole".
One month later, Einstein wrote a paper refuting the Oppenheimer-Snyder paper. Einstein insisted that "Schwartzschild singularities do not exist in physical reality".  After this rebuttal by Einstein, no scientist claimed that General Relativity predicted a singularity while Einstein was alive.
Although scientists did not pursue the black hole concept while Einstein was alive, it became a popular notion of science fiction. There were many stories describing the process of "falling into a black hole".
After computers were applied to the Einstein theory, a decade after Einstein's death, the black hole concept gained acceptance by scientists. Astronomers began to search for black holes, and it is claimed that black holes have actually been found.
The Yilmaz theory does not allow a black hole. It shows that the speed of light never goes to zero, regardless of the mass-to-radius ratio of the star. Yilmaz has proven that the Einstein gravitational field equation is not rigorous, and therefore its black hole solution is a mathematical anomaly. In short, black holes do not exist.
What about the astronomical evidence of black holes? Astronomers are observing massive compact bodies, which they believe to be black holes. The obvious interpretation is that these bodies are actually neutron stars. Astronomers reject this obvious interpretation because the Einstein theory does not allow a massive neutron star. However, the Yilmaz theory shows that massive neutron stars can exist and that the "black hole" observations are consistent with the neutron star interpretation. There is no need to postulate a physically impossible black hole singularity to explain these observations.
