Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the "Timaeus" of Plato, or Socrates in his reflections on what the Greeks called "khôra" (i.e.
List of Tenchi Muyo! characters
The following is a list of the major characters from the anime and manga series "Tenchi Muyo! Ryo-Ohki" and its spin-offs "Tenchi Muyo! GXP", "Tenchi Muyo! War on Geminar", "Tenchi Universe", "Tenchi in Tokyo", "Ai Tenchi Muyo! ", "", "Magical Project S", and "Magical Girl Pretty Sammy". Masaki Kajishima and Hiroki Hayashi, who both worked on the "Bubblegum Crisis" OAVs, cite the show as being the inspiration for "Tenchi Muyo! Ryo-Ohki". In an interview with AIC, Hayashi described "Bubblegum Crisis" as "a pretty gloomy anime. Serious fighting, complicated human relationships, and dark Mega Tokyo."
Keiyō Industrial Zone
, also known as the Keiyō Industrial Region, the Keiyō Industrial Area, or the Keiyō Industrial Belt, is an industrial zone on the northeastern coast of Tokyo Bay that crosses 8 cities in Chiba Prefecture, Japan. The zone spans from the western part of Urayasu in the northeast to Futtsu in the southeast of the region. The zone has no political or administrative status. The name of the industrial zone is formed from two kanji characters. The first, , means "capital city" and refers to Tokyo. The second, , meaning "leaf", is the second kanji in "Chiba" and refers to Chiba Prefecture, and the compound refers to the Tokyo-Chiba region.
Space (mathematics)
In mathematics, a space is a set (sometimes called a universe) with some added structure. Mathematical spaces often form a hierarchy, i.e., one space may inherit all the characteristics of a parent space. For instance, all inner product spaces are also normed vector spaces, because the inner product "induces" a norm on the inner product space such that:  where the norm is indicated by enclosing in double vertical lines, and the inner product is indicated enclosing in by angle brackets. Modern mathematics treats "space" quite differently compared to classical mathematics. In the ancient mathematics, "space" was a geometric abstraction of the three-dimensional space observed in the everyday life.
String theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries gravitational force. Thus string theory is a theory of quantum gravity.
Representation theory of the Lorentz group
The Lorentz group is a Lie group of symmetries of the spacetime of special relativity. This group can be realized as a collection of matrices, linear transformations, or unitary operators on some Hilbert space; it has a variety of representations. In any relativistically invariant physical theory, these representations must enter in some fashion; physics itself must be made out of them. Indeed, special relativity together with quantum mechanics are the two physical theories that are most thoroughly established, and the conjunction of these two theories is the study of the infinite-dimensional unitary representations of the Lorentz group.
Spacetime
In physics, spacetime is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive "where" and "when" events occur. Until the turn of the 20th century, the assumption had been that the three-dimensional geometry of the universe (its description in terms of locations, shapes, distances, and directions) was distinct from time (the measurement of when events occur within the universe). However, Albert Einstein's 1905 "special theory of relativity" postulated that the speed of light through empty space has one definite value—a constant—that is independent of the motion of the light source.

Yeah I'm pretty fascinated by space too. There's so much that we don't know. I don't think I will ever get to go in my life time.

Inflation (cosmology)
In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe. The inflationary epoch lasted from 10 seconds after the conjectured Big Bang singularity to sometime between 10 and 10 seconds after the singularity. Following the inflationary period, the Universe continues to expand, but at a less rapid rate. Inflation theory was first developed by Alan Guth at Cornell in 1979. It developed further in the early 1980s. It explains the origin of the large-scale structure of the cosmos. Quantum fluctuations in the microscopic inflationary region, magnified to cosmic size, become the seeds for the growth of structure in the Universe (see galaxy formation and evolution and structure formation).
Euclidean geometry
Euclidean geometry is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described in his textbook on geometry: the "Elements". Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions (theorems) from these. Although many of Euclid's results had been stated by earlier mathematicians, Euclid was the first to show how these propositions could fit into a comprehensive deductive and logical system. The "Elements" begins with plane geometry, still taught in secondary school as the first axiomatic system and the first examples of formal proof.
Mohr's circle
Mohr's circle, named after Christian Otto Mohr, is a two-dimensional graphical representation of the transformation law for the Cauchy stress tensor. After performing a stress analysis on a material body assumed as a continuum, the components of the Cauchy stress tensor at a particular material point are known with respect to a coordinate system. The Mohr circle is then used to determine graphically the stress components acting on a rotated coordinate system, i.e., acting on a differently oriented plane passing through that point. The abscissa, formula_1, and ordinate, formula_2, of each point on the circle, are the magnitudes of the normal stress and shear stress components, respectively, acting on the rotated coordinate system.
Geometric algebra
The geometric algebra (GA) of a vector space is an algebra over a field, noted for its multiplication operation called the geometric product on a space of elements called multivectors, which is a superset of both the scalars formula_1 and the vector space formula_2. Mathematically, a geometric algebra may be defined as the Clifford algebra of a vector space with a quadratic form. Clifford's contribution was to define a new product, the geometric product, that united the Grassmann and Hamilton algebras into a single structure. Adding the dual of the Grassmann exterior product (the "meet") allows the use of the Grassmann–Cayley algebra (known as 3D projective space or 4D homogeneous space and isomorphic to projective geometry) and a conformal version of the latter together with a conformal Clifford algebra yields a conformal geometric algebra (CGA) providing a framework for classical geometries.
Visual space
Visual space is the perceptual space housing the visual world being experienced by an aware observer; it is the subjective counterpart of the space of physical objects before an observer's eyes. In object space the location and shape of physical targets can be accurately described with the tools of geometry. For practical purposes it is Euclidean. It is three-dimensional and various co-ordinate systems like the Cartesian x,y,z (with a defined origin in relation to an observer's head or eyes), or bipolar with angles of elevation, azimuth and binocular parallax (based on the separation of the two eyes) are interchangeable.
Parallel universes in fiction
A parallel universe is a hypothetical self-contained reality co-existing with one's own. A specific group of parallel universes are called a "multiverse", although this term can also be used to describe the possible parallel universes that constitute reality. While the terms "parallel universe" and "alternative reality" are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term "alternative reality" that implies that the reality is a variant of our own. The term "parallel universe" is more general, without any connotations implying a relationship, or lack of relationship, with our own universe.
