Book Synopsis Gravitational Collapse and Spacetime Singularities by : Pankaj S. Joshi
Download or read book Gravitational Collapse and Spacetime Singularities written by Pankaj S. Joshi and published by Cambridge University Press. This book was released on 2012-09-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical phenomena in astrophysics and cosmology involve gravitational collapse in a fundamental way. The final fate of a massive star when it collapses under its own gravity at the end of its life cycle is one of the most important questions in gravitation theory and relativistic astrophysics, and is the foundation of black hole physics. General relativity predicts that continual gravitational collapse gives rise to a space-time singularity. Quantum gravity may take over in such regimes to resolve the classical space-time singularity. This book investigates these issues, and shows how the visible ultra-dense regions arise naturally and generically as an outcome of dynamical gravitational collapse. It will be of interest to graduate students and academic researchers in gravitation physics, fundamental physics, astrophysics, and cosmology. It includes a detailed review of research into gravitational collapse, and several examples of collapse models are investigated in detail.

Book Synopsis The singularities as ontological limits of the general relativity by : Nicolae Sfetcu

This book was released on 2019-01-31 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: ESSAYS Collection The singularities from the general relativity resulting by solving Einstein's equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their ontology? Is the general theory of relativity a theory that has shown its limits in this case? In this essay I argue that there are singularities, and the general theory of relativity, as any other scientific theory at present, is not valid for singularities. But that does not mean, as some scientists think, that it must be regarded as being obsolete. After a brief presentation of the specific aspects of Newtonian classical theory and the special theory of relativity, and a brief presentation of the general theory of relativity, the chapter Ontology of General Relativity presents the ontological aspects of general relativity. The next chapter, Singularities, is dedicated to the presentation of the singularities resulting in general relativity, the specific aspects of the black holes and the event horizon, including the Big Bang debate as original singularity, and arguments for the existence of the singularities. In Singularity Ontology, I am talking about the possibilities of ontological framing of singularities in general and black holes in particular, about the hole argument highlighted by Einstein, and the arguments presented by scientists that there are no singularities and therefore that the general theory of relativity is in deadlock. In Conclusions I outline and summarize briefly the arguments that support my above views.

Book Synopsis Perspectives in Theoretical Physics by : J. B. Sykes
Download or read book Perspectives in Theoretical Physics written by J. B. Sykes and published by Newnes. This book was released on 2012-12-02 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evgenii Mikhailovich Lifshitz is perhaps best known for his long association with his mentor Lev D Landau, with whom he co-wrote the classic Course of Theoretical Physics, but he was a noted and respected Soviet physicist in his own right. Born in the Ukraine to a scientific family, his long and distinguished career will be remembered for three things - his collaboration with Landau on the internationally acclaimed Course of Theoretical Physics, his work as editor of the Journal of Experimental and Theoretical Physics, and his scientific papers. As well as his work with Landau, E\M\Lifshitz collaborated with many noted Soviet scientists such as I\M\Khalatnikov, I\E\Dyzaloshinskii, V\V\Sudakov, V\A\Belinskii and the editor of this book, L\P\Pitaevskii. Many of the papers presented in this book include their contribution. Collected together they give a comprehensive and penetrating insight into the man and his work, clearly showing Lifshitz's contribution to physics and the influences on his work.
Book Synopsis Defining Gravitational Singularities in General Relativity by :
Download or read book Defining Gravitational Singularities in General Relativity written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Singularities have been a long-standing problem in general relativity. In all other fields of physics, singularities can be easily located and avoided; in general relativity, singularities have an impact on the creation of the manifold, but, by definition, are not even part of real spacetime. Moreover, all singularities in general relativity cannot be treated in the same manner; thus, the classification of singularities is essential in order to understand them. One important class of singularities is curvature singularities, which, in some cases, can be subclassified as central, shell focusing or shell crossing singularities. We propose to further classify curvature singularities as either gravitational or non-gravitational. In general relativity, a curvature singularity is ``located'' where the scalar invariants of the spacetime are undefined. The gradient field of a non-zero scalar invariant can then be calculated, and the end points of the associated integral curves can be determined. If integral curves are attracted to (i.e. intersect) the singularity, then it is a gravitational singularity; if the integral curves avoid the singularity, then it is a non-gravitational singularity. We will test our method by analysing several different spacetimes, including Friedman-Lemaitre-Robertson-Walker, Schwarzschild, self-similar Vaidya, self-similar Tolman-Bondi, non-self-similar Vaidya, and Kerr spacetimes. We find that in every case studied, the integral curves have specific end points, therefore they can be used to classify a curvature singularity as gravitational or non-gravitational. In Friedman-Lemaitre-Robertson-Walker and Schwarzschild spacetimes, we determined that the a(t) = 0 and r = 0 singularities, respectively, are gravitational singularities. In Vaidya and Tolman-Bondi spacetime, we determine that the massless shell focusing singularities are non-gravitational singularities and that the central singularities (which have mass) are gravitational singularities.

Book Synopsis Gravity: Realities of conscious world of singularity by : Aloysius Sebastian
Download or read book Gravity: Realities of conscious world of singularity written by Aloysius Sebastian and published by Aloysius Sebastian. This book was released on 2019-03-19 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of my theories in physics. The main attractions of these theories are some revolutionary thoughts in science like "Gravity has a finite range", the “Big bang scenery inside a black hole” and “particle singularity”. It states that the wave nature of a particle is the product of work done by a particle in a medium. The wave is creating in a medium. Also it states that information can travel faster than light and it can travel in backward direction too. The similarities of the Big bang singularity and the Black hole singularity. In the chapter time travel I am intend to say that, a time traveler cannot create an incident in past or future, he can only meet the information. The chapter 2 and 3 are about the Theory of gravitation. There I am trying to explain the range of gravitational field. For that I have found a new constant "A". It was derivate from the equations of Sir Isaac Newton, the very famous Albert Einstein and many others. According to my Theory and equations, the gravity of an independent object will Zero at a certain distance. Newton and Einstein was discus about the gravitational force of attraction between two objects and I am explaining the range of the gravitational field of an individual object. I cannot believe that, if I have a steel ball with a weight of one kilogram in my hand and someone says to me that, it has an infinite range of gravity, it is out of my logic. I believe in physics and my physics is my surroundings. My observations on surrounding are giving me all my answers. Chapter 1 is discussing the dual nature of a particle. If I am telling somewhere, a "Particle is at rest". People say that, it is impossible to observe a particle at rest. I can't believe that, because we can conclude there is a particle at rest in several occasions. While we are projecting an atom, the particle inside the atom is at rest. If we go tinier particle like a proton, the quarks inside it will be at rest. When the proton is moving, the quark inside it is moving, but it is an inertial motion. It is like, when we are travelling in a bus, we are also moving with the bus. But we don't have any roll in that motion; we are at an inertial motion. Also I asked peoples in some discussions that, what is the nature of a particle at rest? They told me that is showing particle nature at rest. But, then why they are showing dual nature when they are moving?? Here is the presence of a medium, and the waves are creating in the medium. I believe that it is same in microscopic world and macroscopic world. Because of the laws of universe are always same for everything. In the third theory I am explaining about this. We are living in a conscious world where the information can travel faster than light. Everything in our universe is conscious about its state. The light from sun needs 8.20 minutes to reach earth, but we can see the sun at a blink of our eyes, and that describes the speed of information. We are watching a sun which was 8 minutes before. Here the information leads us to the past. Hope you will enjoy reading my book.

Book Synopsis Dynamical Systems by : M. M. Peixoto
Download or read book Dynamical Systems written by M. M. Peixoto and published by Academic Press. This book was released on 2014-05-10 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamical Systems is a collection of papers that deals with the generic theory of dynamical systems, in which structural stability becomes associated with a generic property. Some papers describe structural stability in terms of mappings of one manifold into another, as well as their singularities. One paper examines the theory of polyhedral catastrophes, particularly, the analogues of each of the four basic differentiable catastrophes which map the line. Other papers discuss isolating blocks, the exponential rate conditions for dynamical systems, bifurcation, catastrophe, and a nondensity theorem. One paper reviews the results of functional differential equations which show that a qualitative theory will emerge despite the presence of an infinite dimensionality or of a semigroup property. Another paper discusses a class of quasi-periodic solutions for Hamiltonian systems of differential equations. These equations generalize a well-known result of Kolmogorov and Arnold on perturbations of n-dimensional invariant tori for Hamiltonian systems of n degrees of freedom. The researcher can derive mathematical models based on qualitative mathematical argument by using as "axioms" three dynamic qualities found in heart muscle fibers and nerve axons. The collection can prove useful for mathematicians, students and professors of advanced mathematics, topology or calculus.

Book Synopsis Gravitational Lenses by : P. Schneider
Download or read book Gravitational Lenses written by P. Schneider and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light observed from distant objects is found to be deflected by the gravitational field of massive objects near the line of sight - an effect predicted by Einstein in his first paper setting forth the general theory of relativity, and confirmed by Eddington soon afterwards. If the source of the light is sufficiently distant and bright, and if the intervening object is massive enough and near enough to the line of sight, the gravitational field acts like a lens, focusing the light and producing one or more bright images of the source. This book, by renowned researchers in the field, begins by discussing the basic physics behind gravitational lenses: the optics of curved space-time. It then derives the appropriate equations for predicting the properties of these lenses. In addition, it presents up-to-date observational evidence for gravitational lenses and describes the particular properties of the observed cases. The authors also discuss applications of the results to problems in cosmology.
