Future
The future is the time after the past and present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently existence, exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. In the Western culture, Occidental view, which uses a linear conception of time, the future is the portion of the projected timeline that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone. In the philosophy of time, Philosophical presentism, presentism is the belief that only the present existence, exists and the future and the past are reality, unreal. Religions consider the future when they address issues such as karma, afterlife, life after death, and eschatology, eschatologies that study what the end of time and the end of the ...

Futurology
Futures studies, futures research or futurology is the systematic, interdisciplinary and holistic study of social and technological advancement, and other environmental trends, often for the purpose of exploring how people will live and work in the future. Predictive techniques, such as forecasting, can be applied, but contemporary futures studies scholars emphasize the importance of systematically exploring alternatives. In general, it can be considered as a branch of the social sciences and an extension to the field of history. Futures studies (colloquially called "futures" by many of the field's practitioners) seeks to understand what is likely to continue and what could plausibly change. Part of the discipline thus seeks a systematic and pattern-based understanding of past and present, and to explore the possibility of future events and trends. Unlike the physical sciences where a narrower, more specified system is studied, futurology concerns a much bigger and more comp ...

Time
Time is the continuous progression of existence that occurs in an apparently irreversible process, irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the qualia, conscious experience. Time is often referred to as a fourth dimension, along with Three-dimensional space, three spatial dimensions. Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second, which is defined by measuring the electronic transition frequency of caesium atoms. General relativity is the primary framework for understanding how spacetime works. Through advances in both theoretical and experimental investigations of spacetime, it has been shown ...

Absolute Future
In mathematical physics, the causal structure of a Lorentzian manifold describes the possible causal relationships between points in the manifold. Lorentzian manifolds can be classified according to the types of causal structures they admit (''causality conditions''). Introduction In modern physics (especially general relativity) spacetime is represented by a Lorentzian manifold. The causal relations between points in the manifold are interpreted as describing which events in spacetime can influence which other events. The causal structure of an arbitrary (possibly curved) Lorentzian manifold is made more complicated by the presence of curvature. Discussions of the causal structure for such manifolds must be phrased in terms of smooth curves joining pairs of points. Conditions on the tangent vectors of the curves then define the causal relationships. Tangent vectors If \,(M,g) is a Lorentzian manifold (for metric g on manifold M) then the nonzero tangent vectors at each p ...

Science Fiction
Science fiction (often shortened to sci-fi or abbreviated SF) is a genre of speculative fiction that deals with imaginative and futuristic concepts. These concepts may include information technology and robotics, biological manipulations, space exploration, time travel, Parallel universes in fiction, parallel universes, and extraterrestrials in fiction, extraterrestrial life. The genre often explores human responses to the consequences of projected or imagined scientific advances. Science fiction is related to fantasy (together abbreviated wikt:SF&F, SF&F), Horror fiction, horror, and superhero fiction, and it contains many #Subgenres, subgenres. The genre's precise Definitions of science fiction, definition has long been disputed among authors, critics, scholars, and readers. Major subgenres include hard science fiction, ''hard'' science fiction, which emphasizes scientific accuracy, and soft science fiction, ''soft'' science fiction, which focuses on social sciences.

Karma
Karma (, from , ; ) is an ancient Indian concept that refers to an action, work, or deed, and its effect or consequences. In Indian religions, the term more specifically refers to a principle of cause and effect, often descriptively called the principle of karma, wherein individuals' intent and actions (cause) influence their future (effect): Good intent and good deeds contribute to good karma and happier Reincarnation, rebirths, while bad intent and bad deeds contribute to bad karma and worse rebirths. In some scriptures, however, there is no link between rebirth and karma. In Hinduism, karma is traditionally classified into four types: Sanchita karma (accumulated karma from past actions across lifetimes), Prārabdha karma (a portion of Sanchita karma that is currently bearing fruit and determines the circumstances of the present life), Āgāmi karma (future karma generated by present actions), and Kriyamāṇa karma (immediate karma created by current actions, which may y ...

Present
The present is the period of time that is occurring now. The present is contrasted with the past, the period of time that has already occurred; and the future, the period of time that has yet to occur. It is sometimes represented as a hyperplane in space-time, typically called "now", although modern physics demonstrates that such a hyperplane cannot be defined uniquely for observers in relative motion. The present may also be viewed as a duration. Historiography Contemporary history describes the historical timeframe immediately relevant to the present time and is a certain perspective of modern history. Philosophy and religion Philosophy of time "The present" raises the question: "How is it that all sentient beings experience ''now'' at the same time?" There is no logical reason why this should be the case and no easy answer to the question. In Buddhism Buddhism and many of its associated paradigms emphasize the importance of living in the present moment—being ful ...

Light Cone
In special and general relativity, a light cone (or "null cone") is the path that a flash of light, emanating from a single Event (relativity), event (localized to a single point in space and a single moment in time) and traveling in all directions, would take through spacetime. Details If one imagines the light confined to a two-dimensional plane, the light from the flash spreads out in a circle after the event E occurs, and if we graph the growing circle with the vertical axis of the graph representing time, the result is a Cone (geometry), cone, known as the future light cone. The past light cone behaves like the future light cone in reverse, a circle which contracts in radius at the speed of light until it converges to a point at the exact position and time of the event E. In reality, there are three space Dimension (vector space), dimensions, so the light would actually form an expanding or contracting sphere in three-dimensional (3D) space rather than a circle in 2D, and t ...

Eschatology
Eschatology (; ) concerns expectations of the end of Contemporary era, present age, human history, or the world itself. The end of the world or end times is predicted by several world religions (both Abrahamic religions, Abrahamic and non-Abrahamic), which teach that negative world events will reach a climax. Briefly: the eschaton is the all-inclusive term evoking this predicted climax of a particular theological or political worldview. The scope of expected consequence is global and not local. Eschatology denotes the theory, discussion, techniques, behaviors and orientation toward the eschaton. Theories of afterlife may also be a dimension of eschatology in certain contexts—in these contexts the afterlife of an individual is a kind of hologram or particular microcosm of the overall eschaton. The Eschaton is, furthermore, related to telos: a Greek word simultaneously denoting purpose, climax and end (ie. death, terminus etc. but also perfection, completion etc.). Eschaton is t ...

Philosophical Presentism
Presentism (sometimes 'philosophical presentism') is the view of time which states that only present entities exist (or, equivalently, that everything which is exists presently) and what is present (i.e., what exists) changes as time passes. According to presentism, there are no past or future entities at all, though some entities have existed and other entities will exist. In a sense, the past and the future do not exist for presentists—past events have happened (have existed, or have been present) and future events will happen (will exist, or will be present), but neither exist at all since they do not exist now. Presentism is a view about temporal ontology, i.e., a view about what exists in time, that contrasts with eternalism—the view that past, present and future entities exist (that is, the ontological thesis of the 'block universe')—and with no-futurism—the view that only past and present entities exist (that is, the ontological thesis of the ' growing block unive ...

Divination
Divination () is the attempt to gain insight into a question or situation by way of an occultic ritual or practice. Using various methods throughout history, diviners ascertain their interpretations of how a should proceed by reading signs, events, or omens, or through alleged contact or interaction with supernatural agencies such as ghost, spirits, gods, god-like-beings or the "will of the universe". Divination can be seen as an attempt to organize what appears to be random so that it provides insight into a problem or issue at hand. Some instruments or practices of divination include Tarot card reading, Tarot-card reading, Runic magic, rune casting, Tasseography, tea-leaf reading, automatic writing, water scrying, and psychedelics like psilocybin mushrooms and DMT. If a distinction is made between divination and fortune-telling, divination has a more formal or ritualistic element and often contains a more social character, usually in a religion, religious context, as se ...

Spacetime
In physics, spacetime, also called the space-time continuum, is a 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, space and time took on new meanings with the Lorentz transformation and special theory of relativity. In 1908, Hermann Minkowski presented a geometric interpretation of special relativity that fused time and the three spatial dimensions into a single four-dimensional continuum now known as Minkowski space. This interpretation proved vital t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predeterminism
Predeterminism is the philosophy that all events of history, past, present and future, have been already decided or are already known (by God, fate, or some other force), including human actions. Predeterminism is closely related to determinism. The concept of predeterminism is often argued by invoking causal determinism, implying that there is an unbroken chain of prior occurrences stretching back to infinity. In the case of predeterminism, this chain of events has been pre-established, and human actions cannot interfere with the outcomes of this pre-established chain. Predeterminism can be used to mean such pre-established causal determinism, in which case it is categorised as a specific type of determinism. It can also be used interchangeably with causal determinism—in the context of its capacity to determine future events. Despite this, predeterminism is often considered as independent of causal determinism. The term predeterminism is also frequently used in the context of ...
