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.

"The Reddish Polyergus, the most powerful ants of France by their courage in the fighting, form a people composed of four orders of citizens: males, females, neutrals or warriors ... and slaves, workers conquered on suitable species. 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!"

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

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.

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.

The different possible singularities are defined and the mathematical methods needed to extend the space-time are described in detail in this book. Results obtained (many appearing here for the first time) show that singularities are associated with a lack of smoothness in the Riemann tensor.
