|||
==Contributions to Physics== |
|||
Berman's most important contributions begin with his papers from the early 1980s, such as "Special Law of Variation for Hubble's Parameter" and "Cosmological Models with Constant Deceleration Parameter", where he proposes a constant decelaration parameter, which is nowadays known in the scientific literature as "Berman's Law": according to Özgür Akarsu and Tekin Dereli, Berman’s law has been used for obtaining exact cosmological models in the literature, particularly in the context of dark energy following the discovery of the current acceleration of the universe.<ref>Özgür Akarsu and Tekin Dereli, "Cosmological models with linearly varying deceleration |
|||
parameter"</ref> The cosmological constant problem is considered one of the crucial issues in cosmology. Scientists have collected observational evidences for the accelerated state of the present universe, wherefore is held that the deceleration parameter was positive in the early phases of the matter dominated era, but became negative during the later stages. According to Verma, to obtain exact solutions to the field equations, which would correspond to an accelerated universe, it is necessary to apply a special law of variation for Hubble’s parameter initially proposed by Berman.<ref>M.K. Verma, Mohd. Zeyauddin, Shri Ram, "Anisotropic Cosmological Model With Negative Constant Decelaration Parameter and Time-Decaying Term"</ref> |
|||
=== Proof of Stephen Hawking’s conjecture === |
|||
[[Stephen Hawking]] and [[Alan Guth]] have conjectured that the Universe began with a spontaneous creation, big-banged, and immediately acquired an inflationary accelerated expansion. This conjecture has been proved as theorem by Berman and Luis Augusto Trevisan, through two articles.<ref>Berman, Marcelo Samuel (2009)--"On the zero-energy Universe"--International Journal of Theoretical Physics-48,3278.Doi 10.1007/s10773-009-0125-8</ref><ref>Berman, Marcelo Samuel; Trevisan, Luis Augusto (2010)-"On the creation of the Universe out of nothing"--International Journal of Modern Physics D19,1309-1313.Doi 10.1142/s0218271810017342</ref>{{primary source-inline|date=January 2013}} |
|||
=== Stephen Hawking’s singularity theorem substituted by Berman inexistence of initial infinite singularity theorem === |
|||
Berman redefined the first field [[Friedmann–Lemaître–Robertson–Walker metric|equation of Robertson-Walker´s]] Cosmological Universe, by saying that the total energy density of the Universe, was zero-valued, if the gravitational energy density contribution was taken into consideration. Then, the total energy density is always zero, wherefore there can never be an infinite energy density or singularity.<ref>Berman, Marcelo Samuel(2012)-"Realization of einstein´s Machian Program"-Nova Science Publishers, New York.ISBM 978-1-61942-164-6</ref>{{primary source-inline|date=January 2013}} |
|||
=== Einstein's loose idea, of a "Machian Universe", gained Mathematical, Physical Rigorous definitions, and theorem === |
|||
[[Albert Einstein]] was unable to define what should be exactly understood by a [[Machian Universe]], and he died without establishing the point. Berman defined a Machian Universe, by four postulates, first, the egocentrism, each observer finds himself, in the center of the Universe; second, the sphericity—the Universe resembles a spherical ball; third, the democracy, each observer is equivalent to any other one, so, each observer may find himself, in the center of the ball, but all observers can find themselves alike, at any other location; fourth, the Universe is zero-totally energized. This zero-total-energy, is conserved, i.e., this result is time invariant. There is also, a Theorem stated by Berman, that any Machian Universe, may be studied by Relativistic Cosmology, provided that the radius of the Machian ball be associated with the scale-factor in the Robertson-Walker's metric, and it should also be identified with the radius of the visible or causally-related Universe.<ref>Berman, Marcelo Samuel (2008)-"APrimer in Black Holes, Mach´s Principle, and Gravitational Energy"-Nova Science Publishers, New York.ISBN 978-1-60021-795-1</ref>{{primary source-inline|date=January 2013}} |
|||
=== Stability of the universe === |
|||
Berman and [[Newton da Costa|da Costa]], have proved that the Universe is locally and globally stable ("stable" means, that, if a physical system is displaced from its equilibrium state, it recovers its prior equilibrium state), under General Relativistic theory.<ref>Berman, Marcelo Samuel ; da Costa, Newton Carneiro Affonso(2012)--Journal of Modern Physics vol.3,pp.1211-1216</ref>{{primary source-inline|date=January 2013}} Even if the Universe resembles a [[white hole]] (the reverse of a black-hole), it is stable.<ref>Berman, Marcelo Samuel-Is the Universe a White-hole?. Astrophys. Space Science,311, 359-361,(2007). Los Alamos Archives, http://arxiv.org/abs/physics/0612007</ref> |
|||
=== Entropy Growth in the Universe === |
|||
One of the problems of [[Physical cosmology|Standard Cosmology]] is that the [[perfect fluid]] model, usually considered as valid, is [[Isentropic process|isentropic]] (i.e., the information contents in the Universe, and its "order" or "disorder", remains constant, despite expansion of the Universe) while thermodynamical theorems need growth of entropy with time. Berman solved the problem, by showing that Machian Universes, present growing entropy.<ref>Berman, Marcelo Samuel(2008)--A Primer in Black Holes,Mach´s Principle, and Gravitational Energy-Nova Science Publishers, New York ISBN 978-1-60021-795-1</ref>{{primary source-inline|date=January 2013}} |
|||
=== Positivity of Energy Theorem, for Cosmological Model with "Distant Stars" === |
|||
Berman demonstrated a criterion for positivity (of the non-gravitational) energy in a cosmological model constituted by "distant stars". The condition is that the (non-gravitational) energy density, plus three times the cosmic pressure, divided by the square of the speed of light in vacuum, minus twice the cosmological constant divided by the gravitational constant, is always positive.<ref>Berman, Marcelo Samuel(2012)--General Relativity and the Pioneers Anomaly-Nova Science Publishers, New York ISBN 978-1-62100-003-7</ref>{{primary source-inline|date=January 2013}} |
|||
=== Einstein's Machian program solution === |
|||
Albert Einstein, died frustrated for not having fulfilled his [[Mach's principle|Machian Program]], namely, reconciling the relativistic nature of accelerations in his General and Special Relativity theories, with the Machian requirement, that by looking at the Cosmos, as a whole, absolute accelerations could be found. Berman realized that the solution was considering Universal rotation, so that centripetal absolute decelerations could be found, while keeping intact the General Relativistic Theories. According to Berman, the Pioneers and the FlyBy Nasa anomalies are naturally explained by such rotation. Then, the anomalies can be looked as new experimental verifications of Einstein´s theories.<ref>Berman, Marcelo Samuel (2012)-"General Relativity and the Pioneers anomaly"-Nova Science Publishers, New York.ISBN 978-1-62100-003-7</ref><ref>Berman, Marcelo Samuel (2012)-"Realization of Einstein´s Machian Program",Nova Science Publishers, New York.ISBN 978-1-61942-164-6</ref>{{primary source-inline|date=January 2013}} |
|||
=== Non-confinement and gravitomagnetism of rotating black holes === |
|||
After some papers published by the Indian general relativist [[Contributors to general relativity|K.S. Virbhadra]], it was generally held that [[black hole]]s had their energy and angular momenta confined in their interior. Berman´s Theorems show that the surrounding exterior tridimensional space, also contains their energy and angular momenta.<ref name="Berman, Marcelo Samuel 2007">Berman, Marcelo Samuel (2007)-"Gravitomagnetism and angular Momenta of Black Holes"-RevMexAA 43,(2), 297-302 (2007)</ref>{{primary source-inline|date=January 2013}} |
|||
Berman has also demonstrated the existence of gravitomagnetic energy associated with the rotating black holes. Gravitomagnetism, is a non-linear general relativistic effect caused by moving (rotating) masses, which causes a similar effect as rotating charges in Electromagnetism. He calculated its share to the total energy caused by rotation.<ref name="Berman, Marcelo Samuel 2007"/>{{primary source-inline|date=January 2013}} |
|||
=== Theorems in linearized general relativistic analysis of universal rotation and the Pioneers' anomalies === |
|||
Berman has proved that within the framework of [[Linearized gravity|linearized general relativistic theory]], it is possible to conceive of a deceleration phenomenon due to centripetal effects of universal rotation, affecting any observed point of space, which shows centripetal deceleration as observed by any other observer at any other space-point through the Universe. The observed deceleration is exactly given by the Pioneers anomalous deceleration. He has also demonstrated that there is an equivalent Larmor theorem for gravitation, as well as there is for electromagnetism. Also, Berman found gravitomagnetism effects, in Linearized general relativity.<ref>Beman, Marcelo Samuel-"Realization of Einstein´s Machian Program "(2012)-Nova Science Publishers, New York -ISBN 978-1-61942-164-6</ref>{{primary source-inline|date=January 2013}} |
|||
=== Theorems that show the Universe is a Rotating White Hole === |
|||
Berman's early paper, in 2007, suggested that the universe could be a non-rotating [[white hole]]. Later, Berman considered that the universe had a universal rotational state. In his new books in 2012, he replicated a Kerr rotating white hole that provides a model of the rotating universe.<ref>Berman, Marcelo Samuel (2007)-"Is the Universe a White-Hole?"-Astrophysics and Space Science,311,359-361.Los Alamos Archives http://arxiv.org/abs/physics/0612007</ref><ref>Berman, Marcelo Samuel (2012)--"Realization of Einstein´s Machian Program "(2012)-Nova Science Publishers, New York -ISBN 978-1-61942-164-6</ref>{{primary source-inline|date=January 2013}} |

Marcelo Samuel Berman (born Buenos Aires, Argentina; 10 April 1945) is an Argentine and Brazilian theoretical physicist, specializing in relativistic cosmology, and a journalist. He is the publisher of books dealing with science, philosophy of science and learning techniques.[1][failed verification]
After finishing his engineering degree in electronics, Berman took graduate courses in theoretical physics at ITA, and received a Master of Science in physics in 1981 from the Technological Institute of Aeronautics, under the direction of Fernando de Mello Gomide, followed by a Doctor of Science in physics from the Federal University of Rio de Janeiro in 1988, under the direction of Murari Mohan Som,[1]
He subsequently had post-doctoral studies at Department of Astronomy, University of Florida (1989–90) and part-time adjunct, or visiting positions at Department of Exact Sciences, FURJ (UNIVILLE), in Joinville, SC, Brazil, the University of Alabama, Tuscaloosa, and Group of Cosmology and Gravitation, Division of Astrophysics, National Institute for Space Research (INPE), São José dos Campos, SP, Brazil.[1]
His field of interest is the General Gravitational Theories and Relativistic Cosmology; he has written about one hundred papers in refereed journals and ten books.[citation needed]
From 1996 to 2000, he was Professor, Department of Physics, ITA (Technological Institute of Aeronautics), São José dos Campos.[1][failed verification] He then served as Scientific Counselor, Tecpar (Technological Institute of Paraná). Curitiba, PR -Brazil from (2000-2002) and since 2006, the Scientific Director, Instituto Albert Einstein/Latinamerica, (Curitiba and Mafra).
