Physics Of Black Holes

UFO reports can in many cases be explained by tiny black holes (down antiquarks) floating in the atmosphere. The geomorphology of the locations where these are observed are the explaining factor. It helps to better understand the physics of black holes. Cases in Hessdalen, in Nuremberg, in Basel, in the Vallée des Merveilles and in Krasnoyarsk are surveyed and precisely explained.

First Time

By defining a noncommutative symplectic structure, we study thermodynamics of Schwarzschild black hole in a Snyder noncommutative phase space for the first time. Since natural cutoffs are the results of compactness of symplectic manifolds in phase space, the physics of black holes in such a space would be affected mainly by these cutoffs. In this respect, this study provides a basis for more deeper understanding of the black hole thermodynamics in a pure mathematical viewpoint.

Way Of Thinking

To understand the physics of Black Holes, it is important to understand the first law in Physics which controls our entire universe. This is the law of “Perfect Equilibrium”. Within the entire universe there is always a prefect equilibrium between all the physical forces like gravity, forces of inertia, radiation pressure and Electro-Magnetic Interaction forces at any time, in any direction and at any space coordinate. This is the fundamental law in physics on which also the existence of a Black Hole has been grounded. This new theory will explain the forces within a beam of light interacting with gravity while the beam of light propagates within the gravitational field generated by a black hole.When we look at modern Physics, we can only be impressed by an enormous amount of knowledge and a complete New World of technical applications. We now live in the century of the impressive victory of the new science and the new technology over the old-fashioned world and the old-fashioned way of thinking. Great shifts in the way of thinking and the technological achievements are mostly characterized by an important scientific publication in a century that changes everything in that century. We can recognize the century of Isaac Newton who triggered in 1687 the seismic shift in thinking with his famous publication “Philisophiae Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy). We recognize the century of James Clerk Maxwell who triggered in 1865 the large shift in thinking with his famous publication “A Dynamical Theory of the Electromagnetic Field”.We recognize the century of Albert Einstein who triggered in 1905 the large changings in thinking with his famous theory of Special Relativity represented in his publication “On the Electrodynamics of Moving Bodies”. Manifesting a “New Theory” and a “New Way of Thinking” with important contributions of Hendrik Lorentz, Henri Poincaré and Hermann Minkowski. It is recognizable that with the sudden change in thinking in a new period, a new kind of mutual common sense and a general agreement by many scientists of the new theory and the new way of thinking arises. The “New Theory” will be protected by common sense and mutual agreement. This new way of thinking settles down in the scientific society and become immovable. Other options disappear and simply do not exist anymore. Which will make it almost impossible for the following “New Theory” to rise. The “New Theory” which will be introduced in this article has been based on the fundamental principle of “Perfect Equilibrium within the Universe”. A fundamental universal principle in Physics which has already been expressed by Newton’s famous 3 equations, published in 1687 in “Philosophiae Naturalis Principia Mathematica. Newton’s famous Equations in 3 dimensions will be published in this article in an extension into 4 dimensions. Newton’s 4-dimensional law in the 3 spatial dimensions results in an improved version of the classical Maxwell Equations and Newton’s law in the 4th dimension (time) results in the quantum mechanical Schrödinger wave equation (at non-relativistic velocities) and the relativistic Dirac equation.

Cosmic Censorship Hypothesis

This chapter gives a brief description of Hawking radiation, which involves a combination of general relativity and quantum field theory and leads to a thermodynamical interpretation of the laws governing the evolution of black holes. The study of the Penrose process near a Kerr black hole leads to the conclusion that its irreducible mass can only increase. A similar but more general conclusion was reached by Hawking, who showed that the sum of the areas of the horizons of black holes interacting with matter can only increase, with the condition that the cosmic censorship hypothesis is valid and that the matter obeys the so-called weak energy condition. The chapter concludes with the Israel theorem, which allows one to argue that if gravitation is described by general relativity, then not only do black holes exist, but all black holes are represented by the Kerr–Schwarzschild solution.

Modified Entropy

It has been found recently that the entropy relations of horizons have the universality of black hole mass-independence for many black holes. These universal entropy relations have some geometric and CFT understanding, which may provide further insight into the quantum physics of black holes. In this paper, we present the leading order of black hole entropy sum relations under the quantum corrections. It is found that the modified entropy sum becomes mass-dependent for some black holes in asymptotical (A)dS and flat space–times. We also give an example that the modified entropy sum of regular Bardeen AdS black holes is mass-independent, which may be quantized in the form of the electric charge and the cosmological constant.
