Galactic Empire
Galactic empires are a science fiction setting trope, in which most or all of the habitable planets in the setting's galaxy are ruled by a single centralized political entity. Galactic empires most frequently appear in works in the sub-genres of science fantasy and space opera, although they may appear in other sub-genres as well. Works featuring galactic empires may have them as the story's focus, chronicling the empire's growth and/or decline. Alternatively, they may merely serve as a backdrop against which the events of the story play out. While depictions of galactic empires can vary wildly from work to work, most galactic empires share several key tropes: * The empire, or at least its wealthier and more powerful regions, has advanced considerably in science and technology compared to current human civilization. * Among these advances are some form of faster-than-light travel, which enables transit and communication across the empire's extent to occur in a reasonable ti ...

Space-time
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three-dimensional space, three dimensions of space and the one dimension of time into a single four-dimensional continuum (measurement), continuum. Spacetime diagrams are useful in visualizing and understanding Special relativity, 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 relativity, 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-dimens ...

Democracy
Democracy (from , ''dēmos'' 'people' and ''kratos'' 'rule') is a form of government in which political power is vested in the people or the population of a state. Under a minimalist definition of democracy, rulers are elected through competitive Election, elections while more expansive or maximalist definitions link democracy to guarantees of civil liberties and human rights in addition to competitive elections. In a direct democracy, the people have the direct authority to Deliberation, deliberate and decide legislation. In a representative democracy, the people choose governing officials through elections to do so. The definition of "the people" and the ways authority is shared among them or delegated by them have changed over time and at varying rates in different countries. Features of democracy oftentimes include freedom of assembly, freedom of association, association, personal property, freedom of religion and freedom of speech, speech, citizenship, consent of the governe ...

Parliamentary System
A parliamentary system, or parliamentary democracy, is a form of government where the head of government (chief executive) derives their Election, democratic legitimacy from their ability to command the support ("confidence") of a majority of the legislature, to which they are held accountable. This head of government is usually, but not always, distinct from a ceremonial head of state. This is in contrast to a presidential system, which features a president who is not fully accountable to the legislature, and cannot be replaced by a simple majority vote. Countries with parliamentary systems may be Constitutional monarchy, constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament, or Parliamentary republic, parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is from the legislature. In a few countries, the head of government is also head of state ...

Hybrid Regime
A hybrid regime is a type of political system often created as a result of an incomplete democratic transition from an authoritarian regime to a Democracy, democratic one (or vice versa). Hybrid regimes are categorized as having a combination of autocratic features with democratic ones and can simultaneously hold political repressions and regular elections. According to some definitions and measures, hybrid regimes are commonly found in developing countries with abundant natural resources such as petro-states. Although these regimes experience civil unrest, they may be relatively stable and tenacious for decades at a time. There has been a rise in hybrid regimes since the end of the Cold War. The term ''hybrid regime'' arises from a polymorphic view of political regimes that oppose the dichotomy of autocracy or democracy. Modern scholarly analysis of hybrid regimes focuses attention on the decorative nature of democratic institutions (elections do not lead to a change of power, d ...

Star Wars Prequel Trilogy
The ''Star Wars'' prequel trilogy, colloquially referred to as the prequels, is a series of epic space-opera films written and directed by George Lucas. It was produced by Lucasfilm Ltd. and distributed by 20th Century Fox. The trilogy was released from 1999 to 2005 and is set before the original ''Star Wars'' trilogy (1977–1983), chronologically making it the first act of the Skywalker Saga. Lucas had planned a prequel trilogy (as well as a sequel trilogy) before the release of the original film, but halted major ''Star Wars'' films beyond the original trilogy by 1981. When computer-generated imagery (CGI) had advanced to the level he wanted for the visual effects he wanted for subsequent films, Lucas revived plans for the prequels by the early 1990s. The trilogy marked Lucas's return to directing after the 22-year hiatus following the original ''Star Wars'' film in 1977, as well as a 16-year hiatus between the classic and prequel trilogies. The trilogy consists of '' E ...

It is prominently featured in the prequel trilogy of ''Star Wars'' films, offering a glimpse into its history and functioning. In the original trilogy, which takes place after the events of the prequels, the Republic is referred to as the Old Republic, suggesting its long-established nature. In the prequel era, which takes place during the last years of the Republic, the term "Old Republic" referred to the Galactic Republic of ancient time, which was reorganized into the modern High Republic, a thousand years before the Battle of Yavin (1000 BBY). The Republic is portrayed as a democratic republic-union of sovereign planets, analogous to the United Nations, that has sustained itself peacefully for over twenty-five thousand years but was tied up in layers of bureaucracy, its government ineffective and prone ...

Authoritarianism
Authoritarianism is a political system characterized by the rejection of political plurality, the use of strong central power to preserve the political ''status quo'', and reductions in democracy, separation of powers, civil liberties, and the rule of law. Authoritarian regimes may be either autocratic or oligarchic and may be based upon the rule of a party or the military. States that have a blurred boundary between democracy and authoritarianism have sometimes been characterized as "hybrid democracies", " hybrid regimes" or "competitive authoritarian" states. The political scientist Juan Linz, in an influential 1964 work, ''An Authoritarian Regime: Spain'', defined authoritarianism as possessing four qualities: # Limited political pluralism, which is achieved with constraints on the legislature, political parties and interest groups. # Political legitimacy based on appeals to emotion and identification of the regime as a necessary evil to combat "easily recognizabl ...

Supermassive Black Hole
A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions, of times the mass of the Sun (). Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, including light. Observational evidence indicates that almost every large galaxy has a supermassive black hole at its center. For example, the Milky Way galaxy has a supermassive black hole at its center, corresponding to the radio source Sagittarius A*. Accretion of interstellar gas onto supermassive black holes is the process responsible for powering active galactic nuclei (AGNs) and quasars. Two supermassive black holes have been directly imaged by the Event Horizon Telescope: the black hole in the giant elliptical galaxy Messier 87 and the black hole at the Milky Way's center (Sagittarius A*).
