Download or read book There is not any event horizon written by Carlo Maria Pace and published by Youcanprint. This book was released on 2019-11-27 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the author, by taking into account also the contribution of the gravitational potential energy to the determination of the gravitational masses of the particles in a gravitational field (contrary to the erroneous common use), finds that for the particles with rest mass greater than zero there is always an escape velocity (less than the velocity of light in vacuum c) from any gravitational field and that the particles with rest mass equal to zero are always free to go away from any gravitational field. Consequently, there is not any event horizon, and therefore there is not any black hole. Moreover, the author also shows that the presence of an event horizon would imply the violation of the principle of conservation of energy. In particular, all this is confirmed also by the symmetry with respect to time of the Einstein’s field equation of the General Theory of Relativity and by the correct solutions of this same equation. Consequently, this book can be useful also for explaining in a linear way the possibility of the Big Bang and the possibility of a cyclic universe. Finally, the experimental results are compatible so far with this book.

Download or read book There is not any black hole written by Carlo Maria Pace and published by Youcanprint. This book was released on 2017-01-03 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the author, by starting from the Einstein’s field equation of the General Theory of Relativity, corrects the Schwarzschild solution, and shows that, in the correct Schwarzschild solution, there is not any event horizon and therefore there is not any black hole. Moreover, the author extends all this to its direct consequences, in particular correcting the Kerr solution, the Reissner-Nordstrøm solution and the Kerr-Newman solution. Then, the author extends these four correct solutions (of Schwarzschild, of Kerr, of Reissner-Nordstrøm and of Kerr-Newman) also to the case in which the cosmological constant is greater than zero. On the other hand, the author, by starting from the general form of the Einstein’s field equation of the General Theory of Relativity, demonstrates also in general the non-existence of any event horizon, and therefore the non-existence of any black hole, in the field of application of the General Theory of Relativity. Finally, the author also explores the consequences of all this on the entropy of the Universe, on the Hawking emission process, on the Big Bang Theory and on the astronomical observations.

Download or read book Event Horizon written by Bonni Rambatan and published by John Hunt Publishing. This book was released on 2022-01-28 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an age where Silicon Valley dictates what it means to innovate a painless future, knowledge and enjoyment are fertile breeding grounds of political contestation. But it’s not exactly democracy. We are controlled through platforms that turn us into data for the profit of billionaires. Control has become so playful that we carry it in our pockets, as we continue to crave likes and followers. What is to be done? Should the Left continue to cling to the promise of a political Event, patiently waiting for a revolutionary rupture where new possibilities emerge? Is there a way to delineate its horizons amidst the chaos? Through a psychoanalytic interrogation of the intersections of online culture, sexuality, and politics, Bonni Rambatan and Jacob Johanssen explore such horizons at the limits of capitalism. Event Horizon examines how capitalist ideology functions in our current moment, and, more importantly, how it breaks down. With the increasing urgency of formulating a proper Leftist response to the rapidly growing violence that seriously threatens the lives of marginalised communities, this book could not be more timely.

Download or read book Hawking on the Big Bang and Black Holes written by Stephen W. Hawking and published by World Scientific. This book was released on 1993 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, has made important theoretical contributions to gravitational theory and has played a major role in the development of cosmology and black hole physics. Hawking's early work, partly in collaboration with Roger Penrose, showed the significance of spacetime singularities for the big bang and black holes. His later work has been concerned with a deeper understanding of these two issues. The work required extensive use of the two great intellectual achievements of the first half of the Twentieth Century: general relativity and quantum mechanics; and these are reflected in the reprinted articles. Hawking's key contributions on black hole radiation and the no-boundary condition on the origin of the universe are included. The present compilation of Stephen Hawking's most important work also includes an introduction by him, which guides the reader though the major highlights of the volume. This volume is thus an essentialitem in any library and will be an important reference source for those interested in theoretical physics and applied mathematics. It is an excellent thing to have so many of Professor Hawking's most important contributions to the theory of black holes and space-time singularities all collected together in one handy volume. I am very glad to have them". Roger Penrose (Oxford) "This was an excellent idea to put the best papers by Stephen Hawking together. Even his papers written many years ago remain extremely useful for those who study classical and quantum gravity. By watching the evolution of his ideas one can get a very clear picture of the development of quantum cosmology during thelast quarter of this century". Andrei Linde (Stanford) "This review could have been quite short: 'The book contains a selection of 21 of Stephen Hawking's most significant papers with an overview written by the author'. This w
Download or read book Black Hole Physics written by V. Frolov and published by Springer Science & Business Media. This book was released on 1998-11-30 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduces the physics of black holes and the methods employed in it, and reviews the main results of this branch of physics. Frolov (physics, U. of Alberta) and Novikov (theoretical astrophysics, U. of Copenhagen) focus on questions that have been answered relatively recently. Among the topics treated are: space-time of stationary black holes, general theory of black holes, black hole perturbations, numerics, electrodynamics, black holes in unified theories of gravity, quantum black holes, final states of evaporating black holes, and the information loss puzzle. Special attention is paid to the role of black holes in astrophysics and observational evidence of black hole existence. Many exotic subjects linked with black holes, such as white holes, wormholes, and time machines, are discussed. Appendices cover mathematical aspects of general relativity and black holes and quantum field theory in curved spacetime. Annotation copyrighted by Book News, Inc., Portland, OR

Download or read book Set Theory And Its Applications In Physics And Computing written by Yair Shapira and published by World Scientific. This book was released on 2022-06-24 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why learn set theory? This book provides the answer — it is interesting, and also useful! Taking a new approach and looking from a fresh perspective, the discussion flows in a friendly and transparent way, supplemented with a lot of examples and figures. This makes the theory easily comprehensible: the proofs get vivid and visual, enveloped with interesting applications for students in (applied) math, physics, and engineering. Given the theory and the applications, the book could serve as a textbook in four (undergraduate) math courses: Introduction to set theory and its application; Chaos theory and stability — a geometrical point of view; Functional analysis — Han-Banach theory; and Cryptography with quantum computing. It teaches set theory from the basics, including the axiom of choice, the well ordering theorem, and Zorn's lemma. Furthermore, it uses Cantor's set to introduce chaos theory from a geometrical point of view. Moreover, it introduces the binomial formula (and other related formulas), and uses them in quantum statistical mechanics. And finally, it uses Zorn's lemma in functional analysis, general relativity, and quantum mechanics. There are also practical applications in cryptography, error correction, quantum computing and programming.
Download or read book Classical And Quantum Mechanics With Lie Algebras written by Yair Shapira and published by World Scientific. This book was released on 2021-07-19 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to see physics in its full picture? This book offers a new approach: start from math, in its simple and elegant tools: discrete math, geometry, and algebra, avoiding heavy analysis that might obscure the true picture. This will get you ready to master a few fundamental topics in physics: from Newtonian mechanics, through relativity, towards quantum mechanics.Thanks to simple math, both classical and modern physics follow and make a complete vivid picture of physics. This is an original and unified point of view to highlighting physics from a fresh pedagogical angle.Each chapter ends with a lot of relevant exercises. The exercises are an integral part of the chapter: they teach new material and are followed by complete solutions. This is a new pedagogical style: the reader takes an active part in discovering the new material, step by step, exercise by exercise.The book could be used as a textbook in undergraduate courses such as Introduction to Newtonian mechanics and special relativity, Introduction to Hamiltonian mechanics and stability, Introduction to quantum physics and chemistry, and Introduction to Lie algebras with applications in physics.
Download or read book Astrophysical Concepts written by Martin Harwit and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: My principal aim in writing this book was to present a wide range of astrophysical topics in sufficient depth to give the reader a general quantitative understanding of the subject. The book outlines cosmic events but does not portray them in detail-it provides aseries of astrophysical sketches. I think this approach befits the present uncertainties and changing views in astrophysics. The material is based on notes I prepared for a course aimed at seniors and beginning graduate students in physics and astronomy at Cornell. This course defined the level at which the book is written. For readers who are versed in physics but are unfamiliar with astronomical terminology, Appendix A is included. It gives a brief background of astronomical concepts and should be read before starting the main text. The first few chapters outline the scope of modern astrophysics and deal with elementary problems concerning the size and mass of cosmic objects. However, it soon becomes apparent that a broad foundation in physics is needed to proceed. This base is developed in Chapters 4 to 7 by using, as ex am pIes, specific astronomi cal situations. Chapters 8 to 10 enlarge on the topics first outlined in Chapter I and show how we can obtain quantitative insights into the structure and evolution of stars, the dynamics of co~mic gases, and the large-scale behavior of the universe.
