Petz Map, Black Hole Interior Reconstruction, and Papadodimas-Raju Proposal| Chapter 2 | Current Research Progress in Physical Science Vol. 2

 

The black hole information paradox is one of the important questions of physics in the last few decades. We study the reconstruction of the bulk operators in AdS/CFT when the geometry contains a black hole. The black hole exterior can be mapped to the CFT via a very simple Petz map which coincides with the HKLL map reconstruction of the black hole exterior. For the interior modes of the bulk theory, using the definition of the Petz recovery channel in modular theory, we can find the mapping from the black hole interior to the dual boundary theory. In the case of the evaporating black hole, it is expected that the interior modes map to some operators that have support only on the bath system, the cavity that absorbs the Hawking radiation. The most important observation that we have here is that in the case that we have a typical black hole microstate in the bulk, the CFT dual of the interior modes that we can find using the Petz recovery channel are exactly the operators that so-called "mirror operator " in the Papadodimas-Raju proposal. The main idea of the PR proposal is to focus on a code subspace of the CFT theory, which is created by acting with a small algebra on the corresponding pure state and then fnd the CFT description of the interior operator in a state-dependent manner just in the chosen code subs. Therefore, we can interpret Papadodimas- Raju proposal as an example of the Petz map reconstruction. It may help us answer some open questions about their procedure.

A New Concept of the Structure of the Universe | Chapter 7 | Current Perspective to Physical Science Research Vol. 3

 Based on a cosmological model outside singularity, a possible building of the universe is presented. It is confirmed that there must simultaneously be two sorts of proportion breaking in the universe. The universe is composed of limitless s- cosmic islands, limitless v-cosmic islands and limitless transition zones. The existing and changeful forms of the cosmic islands must differ from each other. The cosmological law holds only approximately inside a cosmic island. No facts can be exchanged 'tween a s-cosmic island and an abutting v-cosmic island for fear that every observer thinks welcome cosmic island expected the whole universe. It is attainable that some cosmic isles are contracting, some universal islands are expanding, and different cosmic islands are fixed for a time. But the universe all at once is always invariable and holds all possible existing forms of matter. To present a possible explanation for stray quasars, quasars and the sources of high strength protons. To predict that giant voids have concave take a picture with a camera effects, tremendous black holes will mold into white holes and the gravitational interplay between galaxy clusters will be feebler and the gravitational. interaction inside galaxy will be more powerful than those predicted by the normal theory.

Supreme Theory of Everything: A Descriptive Study| Chapter 5 | New Frontiers in Physical Science Research Vol. 6

 Not only outer space, but everything has a accepted character to a degree eternal, infinite, recurrent, and wave-particle two of something. Everything from elementary atoms to celestial corpses is in eternal motions, the base of that dissects only into a circle. It means that entirety is described only by trigonometry. Science cannot describe the entire advantage of the harmonic cosmos without the use of arithmetic and the mathematical circle. Other designs may be excellent, but they are not outside flaws. Some parts are very refined, while others are puzzling. Gravity, according to the General Theory of Relativity, is lines. All particles are detailed by the wave function of trigonometry in branch of quantum physics. This paper shows few possibilities of arithmetic, particularly arithmetic circles for the projection of circle, uniqueness, the sensitivity of entirety formula and questions of the temperature scales in Hertzsprung-Russel Diagram, evolutionary past of the Earth’s climate, makeup of whole universe, and the parallel universes.

An Addendum to Einstein’s Whole Theory of Universe | Chapter 4 | New Trends in Physical Science Research Vol. 5

 "Let me complete the circle," Einstein remarked at the end of his lecture, and "We have finished the circle" is the first phrase of our poem. We used to believe that the universe within an atom was like a galaxy of particles and subatomic particles, with each photon containing a galaxy of sub-photons. At the core of each atom and subatomic particle is an energy pool that stores energy. This energy pool generates particles, i.e. energy is turned into particles. Particles are changing into energy while being ensnared by the energy pool in some subatomic galaxies. The mysteries of atoms and galaxies were exposed via magnification. Based on enlarged photos of atoms and subatomic particles, we inferred that atoms and galaxies are wrapped in folds. The researchers also revealed that there are two sorts of stuff in the universe: luminous (stars) and non-luminous (planets, moons). The core of luminous matter (galaxies) is a white hole, while the centre of non-luminous matter is a black hole (galaxies). White holes and black holes, respectively, are the energy pools.

A Potential Barrier Halting Spherically Symmetric Relativistic Gravitational Collapse | Chapter 9 | Research Trends and Challenges in Physical Science Vol. 1

 Geodesic pathways of radially inbound photons in a Schwarzschild space-time approach the critical radius of a collapsed star asymptotically for asymptotic observers. Inbound null geodesics in a matching Vaidya space-time, however, pass through a temporary inflection point when time dilation diverges and then reach the critical radius within a finite coordinate time when considering accretion or quantum evaporation processes. Photons approaching on radial pathways pass through the inflection point and suffer infrared divergence at the critical radius when using a diagonal variant of the Vaidya metric that reduces to the Schwarzschild metric in the zero accretion/evaporation limit. Beyond the inflection point, particles on radial timelike geodesics encounter a potential barrier, which diverges at the critical radius.

The Big Bang – An Alternative Theory | Chapter 7 | Newest Updates in Physical Science Research Vol. 3

 The Big Bang theory seeks to understand the origin of the universe by positing a singularity, a very small and dense body. The inflation theory, which proposes a “metric” expansion of space [1,2] that grows faster than the speed of light at first and then begins to increase, is the most widely accepted explanation. Some physicists disagree with this principle [3]. The Big Bang, according to this alternate theory, was caused by the collision of two singularities.

Negative Weight Modular Forms and Black Hole Entropy: Logarithmic Corrections| Chapter 9 | New Insights into Physical Science Vol. 11

We present a method of finding logarithmic corrections, up to an arbitrary order, of different quantities, such as black hole entropy in extreme CFT, or the entropy of p-branes compactified on a Kaluza-Klein space-time, by way of an elementary observation on the equivalent formulation of a certain asymptoticity in terms of a Bessel equation. In the more general mathematical context of negative weight modular forms, we indicate how some of the known work of physicists can be interpreted. A few minor mistakes are corrected in the literature. A good description of the paper is given in the concluding remarks in section 5.

Light Deflection around a Spherical Charged Black Hole to Second Order. Multivariate Padé Approximants| Chapter 9 | New Insights into Physical Science Vol. 10

The second-order terms for the deflection of light around a large, spherical and charged black hole are derived from the Reissner-Nordström metric using the Lindstedt-Poincaré method to solve the equation of motion of a photon around a compact object. The corrections are performed to establish the expansion in terms of

In addition, we obtain multivariate Padé approximants from the expansion of the disruption. We also illustrate how these are a better fit than the original formal Taylor series for the numerical results.

The Secular Increase of Astronomical Unit due to the Loss of the Solar Mass: Scientific Explanation | Chapter 5 | New Insights into Physical Science Vol.4

 According to our published articles [1,2], this article is to further derive the relationships between the inward / outward speed, the central mass, the radius and the cross-radial velocity of a gravitationally bound point and to prove the equations with error less than 2.2% using real data [3,4]. Besides, using our method of raw data processing, we found that our processed data conforms to G. A. Krasinsky’s conclusion of 15 (Cm/Year) For the secular increase of astronomical unit [3]. Now, using our equations, we can accurately calculate and prove the secular increase of astronomical unit is due to the loss of the solar mass to answer the questions that can not be answered by known theories [5].
