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.

I am neutral, and I am proud of it. Is there a life more noble, more chivalrous than mine: to fight, to conquer or to die!... We live for years, and all this time we spend it to serve the country and the nation, to contribute to its greatness, to its power; to make us serve as kings ... and enjoy the sun!"

Book excerpt: The sixteen papers collected in this volume are expanded and revised versions of talks delivered at the Second International Conference on the Ontology of Spacetime, organized by the International Society for the Advanced Study of Spacetime (John Earman, President) at Concordia University (Montreal) from 9 to 11 June 2006. Most chapters are devoted to subjects directly relating to the ontology of spacetime. The book starts with four papers that discuss the ontological status of spacetime and the processes occurring in it from a point of view that is first of all conceptual and philosophical. The focus then slightly shifts in the five papers that follow, to considerations more directly involving technical considerations from relativity theory. After this, Time, Becoming and Change take centre stage in the next five papers. The book ends with two excursions into relatively uncharted territory: a consideration of the status of Kaluza-Klein theory, and an investigation of possible relations between the nature of spacetime and condensed matter physics, respectively. Space and time in present-day physics and philosophy Relatively low level of technicality, easily accessible Introduction from scratch of the debates surrounding time Broad spectrum of approaches, coherently represented

Available in PDF, EPUB and Kindle. Book excerpt: The concept of God according to traditional Judeo-Christian-Islamic theism minimally includes the following theses: (i) There is one God; (ii) God is an omniscient, omnipotent, and morally perfect agent; (iii) God is the creator ex nihilo of the universe and the sustainer of all that exists; and (iv) God is an immaterial substance that is ontologically distinct from the universe. Proponents of alternative concepts of God, such as pantheism, panentheism, religious anti-realism, developmental theism, and religious naturalism, exclude at least one of these claims. A number of prominent philosophers and scientists have expressed sympathy with alternative concepts of the divine. However, voices raised in defense of these concepts tend not to be taken seriously in contemporary analytic philosophy of religion. This volume aims to shed light on alternative concepts of God and to thoroughly consider their merits and demerits. The contributors are leading analytic philosophers of religion, including critics of these views as well as sympathizers. This is the first contemporary edited collection featuring the work of analytic philosophers of religion covering such a wide range of alternative concepts of God.

Available in PDF, EPUB and Kindle. Book excerpt: This Thesis deals with recent progress regarding singularities in General Relativity. Singularities are predicted by the theory, but raise difficult problems, because they make the usual equations to be plagued with infinities and to break down. To resolve some of these problems, extensions of differential geometry and of Einstein's equation to singularities were needed, and were constructed by the author. This generalization works easily at the Big-Bang singularity, which gained by this a description in terms of finite quantities which have both geometric and physical meaning. Moreover, a large class of Big-Bang singularities which are not necessarily homogeneous or isotropic is presented. In addition, these singularities satisfy the Weyl curvature hypothesis, emitted by Penrose to explain the arrow of time. The black hole singularities apparently are more difficult to deal with, but by applying a special procedure they turn out as well to admit a description in terms of finite quantities. In addition, these singularities exhibit a (geo)metric dimensional reduction, which might act as a regulator for the quantum fields, including for quantum gravity, in the high-energy limit. This opens the perspective of perturbative quantum gravity without modifying General Relativity.

This book was released on 2023-10-15 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signals in the Noise: An Exploration of Consciousness and Reality. How Current Research is Challenging Materialist Science "The Signals in the Noise," groundbreaking theories about consciousness are meticulously explored, presenting an avant-garde perspective that stands to challenge our traditional, materialist viewpoints. The author leads us on an intellectual journey, questioning established materialist scientific norms and bringing forward evidence that defies materialist theories of consciousness. The book emphasizes that consciousness persists and can even be enhanced when brain activity decreases, supported by numerous research studies involving psychedelics, near-death experiences, and other instances when brain functions are diminished. This new understanding suggests that consciousness transcends the physical confines of our biological makeup, challenging conventional notions about its origin and nature. Furthermore, the book introduces a transformative perspective on the universe, proposing that what we perceive as material is merely a function of our sensory systems. Based on the author's review of current theories of the composition of the cosmos, we now know everything that exists is composed of energy, with physicality representing deeper qualities that lie out of our reach. Drawing on proven quantum physics, the author presents the theory that the universe's interconnectedness is a product of coherent quantum fields from which everything emerges and takes on the character of separateness and materiality in the 4D or manifest level we experience. In a radical departure from mainstream materialist thought, "The Signals in the Noise" argues that consciousness is a universal phenomenon occurring in varying degrees of complexity across all organisms. The author posits that while the presence of proto-consciousness is universal, the consciousness we experience emerges in the fourth-dimensional or manifest level, an idea that, if widely accepted, can redefine our understanding of life and existence. Finally, the author criticizes the materialist worldview, stating that this ingrained belief system creates many societal, political, religious, and environmental problems. He argues that our obstinate adherence to materialist orthodoxy drives our trajectory toward planetary destruction. Catalyzed by our capitalist system of consumption, this materialist belief system hinders our ability to recognize and correct the adverse effects of our actions. "The Signals in the Noise" is a compelling critique of the materialist worldview, challenging our understanding of consciousness, existence, and our place in the universe. It underscores the urgency to redefine our perspectives to avert the catastrophic trajectory that our current beliefs are driving us toward. This book is a radical and thought-provoking read for anyone interested in consciousness, quantum physics, and the future of our planet.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date overview of the foundations of spacetime physics. It features original essays written by world-class experts in the physics and philosophy of spacetime. The foundational questions regarding the origin and nature of spacetime are branching into new and exciting directions. These questions are not restricted to the quantum gravity program but also arise in the context of a well-established theory like general relativity. Against the background of these quick and diverse developments, this volume features a broad range of perspectives on spacetime. Part I focuses on the nature of spacetime in non-quantum theories, such as Newtonian mechanics and relativity. Part II explores some intriguing conceptual implications of developing a quantum theory of spacetime. The Foundations of Spacetime Physics is an essential resource for scholars and advanced students working in philosophy of physics, philosophy of science, and scientific metaphysics.

Available in PDF, EPUB and Kindle. Book excerpt: In Singularities at the Threshold: The Ontology of Unrest, Bruno Gullì calls into question the concept of the independent and sovereign individual of the liberal (and neoliberal) tradition from the standpoint of the ontology of singularity, that is, the plural constitution of what appears to be an individual. Singularity is not the result of a process of individuation, but the process itself. He argues that the process of individuation—whereby at each stage everything appears to be individuated as such, to be an individual thing—is in reality always already plural, a process of transindividuation, or better, trans-dividuation. Gullì further examines why singularity is usually confused with individuality; what comes after the sovereign and independent individual, after the subject; and what the role of subversive and liberated singularities is in bringing about a new ethos and a better world.

Available in PDF, EPUB and Kindle. Book excerpt: Scientists have always attempted to explain the world in terms of a few unifying principles. In the fifth century B.C. Democritus boldly claimed that reality is simply a collection of indivisible and eternal parts or atoms. Over the centuries his doctrine has remained a landmark, and much progress in physics is due to its distinction between subjective perception and objective reality. This book discusses theory reduction in physics, which states that the whole is nothing more than the sum of its parts: the properties of things are directly determined by their constituent parts. Reductionism deals with the relation between different theories that address different levels of reality, and uses extrapolations to apply that relation in different sciences. Reality shows a complex structure of connections, and the dream of a unified interpretation of all phenomena in several simple laws continues to attract anyone with genuine philosophical and scientific interests. If the most radical reductionist point of view is correct, the relationship between disciplines is strictly inclusive: chemistry becomes physics, biology becomes chemistry, and so on. Eventually, only one science, indeed just a single theory, would survive, with all others merging in the Theory of Everything. Is the current coexistence of different sciences a mere historical venture which will end when the Theory of Everything has been established? Can there be a unified description of nature? Rather than an analysis of full reductionism, this book focuses on aspects of theory reduction in physics and stimulates reflection on related questions: is there any evidence of actual reduction? Are the examples used in the philosophy of science too simplistic? What has been endangered by the search for (the) ultimate truth? Has the dream of reductionist reason created any monsters? Is big science one such monster? What is the point of embedding science Y within science X, if predictions cannot be made on that basis?

Book excerpt: Black holes are one of the most fascinating predictions of general relativity. They are the natural product of the complete gravitational collapse of matter and today we have a body of observational evidence supporting the existence of black holes in the Universe. However, general relativity predicts that at the center of black holes there are spacetime singularities, where predictability is lost and standard physics breaks down. It is widely believed that spacetime singularities are a symptom of the limitations of general relativity and must be solved within a theory of quantum gravity. Since we do not have yet any mature and reliable candidate for a quantum gravity theory, researchers have studied toy-models of singularity-free black holes and of singularity-free gravitational collapses in order to explore possible implications of the yet unknown theory of quantum gravity. This book reviews all main models of regular black holes and non-singular gravitational collapses proposed in the literature, and discuss the theoretical and observational implications of these scenarios.

During the last thirty years this notion has been object of an intense critical review in the light of new scientific theories which try to combine the principles of both general relativity and quantum theory—called theories of quantum gravity. This book considers the way string theory shapes its own account of spacetime disappearance from the fundamental level.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores the role of singularities in general relativity (GR): The theory predicts that when a sufficient large mass collapses, no known force is able to stop it until all mass is concentrated at a point. The question arises, whether an acceptable physical theory should have a singularity, not even a coordinate singularity. The appearance of a singularity shows the limitations of the theory. In GR this limitation is the strong gravitational force acting near and at a super-massive concentration of a central mass. First, a historical overview is given, on former attempts to extend GR (which includes Einstein himself), all with distinct motivations. It will be shown that the only possible algebraic extension is to introduce pseudo-complex (pc) coordinates, otherwise for weak gravitational fields non-physical ghost solutions appear. Thus, the need to use pc-variables. We will see, that the theory contains a minimal length, with important consequences. After that, the pc-GR is formulated and compared to the former attempts. A new variational principle is introduced, which requires in the Einstein equations an additional contribution. Alternatively, the standard variational principle can be applied, but one has to introduce a constraint with the same former results. The additional contribution will be associated to vacuum fluctuation, whose dependence on the radial distance can be approximately obtained, using semi-classical Quantum Mechanics. The main point is that pc-GR predicts that mass not only curves the space but also changes the vacuum structure of the space itself. In the following chapters, the minimal length will be set to zero, due to its smallness. Nevertheless, the pc-GR will keep a remnant of the pc-description, namely that the appearance of a term, which we may call "dark energy", is inevitable. The first application will be discussed in chapter 3, namely solutions of central mass distributions. For a non-rotating massive object it is the pc-Schwarzschild solution, for a rotating massive object the pc-Kerr solution and for a charged massive object it will be the Reissner-Nordström solution. This chapter serves to become familiar on how to resolve problems in pc-GR and on how to interpret the results. One of the main consequences is, that we can eliminate the event horizon and thus there will be no black holes. The huge massive objects in the center of nearly any galaxy and the so-called galactic black holes are within pc-GR still there, but with the absence of an event horizon! Chapter 4 gives another application of the theory, namely the Robertson-Walker solution, which we use to model different outcomes of the evolution of the universe. Finally the capability of this theory to predict new phenomena is illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: In this compendium of essays, some of the world’s leading thinkers discuss their conceptions of space and time, as viewed through the lens of their own discipline. With an epilogue on the limits of human understanding, this volume hosts contributions from six or more diverse fields. It presumes only rudimentary background knowledge on the part of the reader. Time and again, through the prism of intellect, humans have tried to diffract reality into various distinct, yet seamless, atomic, yet holistic, independent, yet interrelated disciplines and have attempted to study it contextually. Philosophers debate the paradoxes, or engage in meditations, dialogues and reflections on the content and nature of space and time. Physicists, too, have been trying to mold space and time to fit their notions concerning micro- and macro-worlds. Mathematicians focus on the abstract aspects of space, time and measurement. While cognitive scientists ponder over the perceptual and experiential facets of our consciousness of space and time, computer scientists theoretically and practically try to optimize the space-time complexities in storing and retrieving data/information. The list is never-ending. Linguists, logicians, artists, evolutionary biologists, geographers etc., all are trying to weave a web of understanding around the same duo. However, our endeavour into a world of such endless imagination is restrained by intellectual dilemmas such as: Can humans comprehend everything? Are there any limits? Can finite thought fathom infinity? We have sought far and wide among the best minds to furnish articles that provide an overview of the above topics. We hope that, through this journey, a symphony of patterns and tapestry of intuitions will emerge, providing the reader with insights into the questions: What is Space? What is Time?
