The universe has two main dimensions spatial dimension (consists of three dimensions directional X, Y, Z) and the other dimension is the temporal dimension. Time and space are linked strongly inseparable so we will consider the time and place one Is the dimension of spacetime (as proved Einstein in his theory of relativity). Spacetime dimension includes the temporal dimension and spatial dimension (the three dimensions of space).  Spacetime dimension two (real spacetime – Vision spacetime).  Spacetime has two cases:    1- Navigate spacetime       2- The change in spacetime. spacetime is Personally like a fingerprint and it always variable ( everyone has Personally spacetime and there are not find two of spacetime are the same.

“Go outside your realm of experience, on a hypercube” explains how and why mathematicians conceive of cubes in many dimensions, including a four-dimensional hypercube. Einstein’s special theory of relativity and the mathematics of string theory—a subfield of physics that seeks to understand the structure of the universe—both require more than the three dimensions with which we are familiar. The discussion, which focuses on how to make a four-dimensional hypercube, is enhanced with numerous hand-drawn sketches. Mathematics students and enthusiasts are encouraged to go outside their realm of experience in both mathematical and life pursuits. At the chapter’s end, readers may check their understanding by working on a problem. A solution is provided.

The theories of quantum mechanics and relativity dramatically altered our understanding of the universe ushering in the era of modern physics. Quantum theory deals with objects probabilistically at small scales, whereas relativity deals classically with motion in space and time. We show here that the mathematical structures of quantum theory and of relativity follow together from pure thought, defined and uniquely constrained by the same elementary ``combining and sequencing'' symmetries that underlie standard arithmetic and probability. The key is uncertainty, which inevitably accompanies observation of quantity and imposes the use of pairs of numbers. The symmetries then lead directly to the use of complex \sqrt{-1} arithmetic, the standard calculus of quantum mechanics, and the Lorentz transformations of relativistic spacetime. One dimension of time and three dimensions of space are thus derived as the profound and inevitable framework of physics.

The effects of various combinations of modalities with the dimensions of space and time on reproduction of stimulus patterns by 162 normal and 83 reading-disabled children aged 6 to 12 yr. was studied. Scores on three subtests with three different combinations of modalities with space and time dimensions were analyzed. They were (a) visual temporal input, vocal temporal output; (b) auditory temporal input, vocal temporal output; and (c) visual spatial-temporal input, vocal temporal output. Visual spatial-temporal input was superior to the other subtests. Auditory temporal input was superior to visual temporal input. There were significant differences between normal and reading-disabled subjects on each subtest so the spatial dimension gives an advantage. The spatial and temporal dimensions need to be attended to in research.

FOKA SZUMEJOWY'S JOURNEYS TO THE SOURCE. THE NAVEL OF THE EARTH AS PRESENTED BY STANISŁAW VINCENZContinuing Jacek Kolbuszewski’s exegesis of the spatial orders in Stanisław Vincenz’s Na wysokiej połoninie On the High Mountain Pastures, the author of the article attempts to recreate the “philosophy of space” as formulated by the Homer of the Hutsuls. He carries out a detailed analysis of two fragments of the Hutsul epic: Maksym the seer’s story of a rock church from Barwinkowy wianek Periwinkle Wreath and Foka Szumejowy’s expedition to the navel of the earth described in Zwada Squabble. In both case inspirations from Dante’s Divine Comedy can be seen primarily in the expansion of space: on the one hand to include the world of the dead and on the other — the universe understood in Platonic terms. Both journeys also have many characteristics testifying to their initiation-related nature. Particularly important in this respect is the expedition undertaken by Foka and his friends to the source of the Cheremosh River deep inside the Palenica Mountain, on top of which Wincenty Pol placed the point where the borders of three countries — Poland, Hungary and Romania — met. Although in the light of modern research such a location of the old border between the three states is wrong, this is precisely where Vincenz places the navel of the earth. It appear as a distant echo of the omphalos stone from Delphi; a mystical place marked by extraordinarily dense symbolism: centre of the world, bringing together the heavenly and the earthly orders, the living and the dead, and annihilating the temporal dimension. The interpretation of the symbolism of Vincenz’s navel of the world is complemented by Klucz Key, which opens Zwada and in which the author suggests a universal dimension of the history of culture, and, at the same time, mystery-like nature of art, especially literature.]]>

In order to reduce power consumption and save storage capacity, we propose a high-resolution sub-Nyquist radar approach based on matrix completion (MC), termed as single-channel sub-Nyquist-MC radars. While providing the high-resolution joint angle-Doppler estimation, this proposed radar approach minimizes the number of samples in all three dimensions, that is, the range dimension, the pulse dimension (also named temporal dimension), and the spatial dimension. In range dimension, we use a single-channel analog-to-information converter (AIC) to reduce the number of range samples to one; in both spatial and temporal dimensions, we employ a bank of random switch units to regulate the AICs, which greatly reduce the number of spatial-temporal samples. According to the proposed sampling scheme, the samples in digital processing center forwarded by M receive nodes and N pulses are only a subset of the full matrix of size M times N. Under certain conditions and with the knowledge of the sampling scheme, the full matrix can be perfectly recovered by using MC techniques. Based on the recovered full matrix, this paper addresses the problem of the high-resolution joint angle-Doppler estimation by employing compressed sensing (CS) techniques. The properties and performance of the proposed approach are demonstrated via simulations.

AbstractBinary black holes as the recently detected sources of gravitational waves can be formed from massive stellar binaries in the field or by dynamical interactions in clusters of high stellar density, if the black holes are the remnants of massive stars that collapsed without natal kicks that would disrupt the binary system or eject the black holes from the cluster before binary black hole formation. Here are summarized and discussed the kinematics in three dimensions of space of five Galactic black hole X-ray binaries. For Cygnus X-1 and GRS 1915+105 it is found that the black holes of ~15 M⊙ and ~10 M⊙ in these sources were formed in situ, without energetic kicks. These observations suggest that binary black holes with components of ~10 M⊙ may have been prolifically produced in the universe.

Modern general theory of relativity considers gravity as the curvature of space-time. The theory is based on the principle of equivalence. All bodies fall with the same acceleration in the gravitational field, which is equivalent to locally accelerated reference systems. In this article, we will affirm the concept of gravity as the curvature of the relative wave function of the Universe. That is, a change in the phase of the universal wave function of the Universe near a massive body leads to a change in all other wave functions of bodies. The main task is to find the form of the relative wave function of the Universe, as well as a new equation of gravity for connecting the curvature of the wave function and the density of matter.

The Euclidean geometry was developed as a mathematical system due to generalizing thousands years of measurements on the plane and spherical surfaces. The development of celestial mechanics and stellar astronomy confirmed its validity as mathematical principles of natural philosophy, in particular for studying the Solar System bodies’ and Galaxy stars motions. In the non-Euclidean geometries by Lobachevsky and Riemann, the third axiom of modern geometry manuals is substituted. We show that the third axiom of these manuals is a corollary of the Fifth Euclidean postulate. The idea of spherical, Riemannian space of the Universe and local curvatures of space, depending on body mass, was inculcated into celestial mechanics, astronomy and geodesy along with the theory of relativity. The mathematical apparatus of the relativity theory was created from immeasurable quantities

This chapter is the first of this book to deal specifically with the metaphysics of time. This chapter defends the pure manifold theory of time. On this view, time is just another dimension of extent like the three dimensions of space, the past, present, and future are equally real, and the world is at bottom tenseless. What is true is eternally true. For example, it is now true that there will be a sea fight tomorrow or that there will not be a sea fight tomorrow. It is argued that the pure manifold theory does not entail fatalism and that contingent statements about the future do not imply that only the past and present exist.

AbstractGalaxy groups offer an important perspective on how the large-scale structure of the Universe has formed and evolved, being great laboratories to study the impact of the environment on the evolution of galaxies. We aim to investigate the properties of a galaxy group that is gravitationally lensing HELMS18, a submillimeter galaxy at z = 2.39. We obtained multi-object spectroscopy data using Gemini-GMOS to investigate the stellar kinematics of the central galaxies, determine its members and obtain the mass, radius and the numerical density profile of this group. Our final goal is to build a complete description of this galaxy group. In this work we present an analysis of its two central galaxies: one is an active galaxy with z = 0.59852 ± 0.00007, while the other is a passive galaxy with z = 0.6027 ± 0.0002. Furthermore, the difference between the redshifts obtained using emission and absorption lines indicates an outflow of gas with velocity v = 278.0 ± 34.3 km/s relative to the galaxy.
