Ecumenopolis in the context of "Ekistics"

Technosignature or technomarker is any measurable property or effect that provides scientific evidence of past or present technology. Technosignatures are analogous to biosignatures, which signal the presence of life, whether intelligent or not. Some authors prefer to exclude radio transmissions from the definition, but such restrictive usage is not widespread. Jill Tarter has proposed that the search for extraterrestrial intelligence (SETI) be renamed "the search for technosignatures". Various types of technosignatures, such as radiation leakage from megascale astroengineering installations such as Dyson spheres, the light from an extraterrestrial ecumenopolis, or Shkadov thrusters with the power to alter the orbits of stars around the Galactic Center, may be detectable with hypertelescopes. Some examples of technosignatures are described in Paul Davies's 2010 book The Eerie Silence, although the terms "technosignature" and "technomarker" do not appear in the book.

In February 2023, astronomers reported, after scanning 820 stars, the detection of 8 possible technosignatures for follow-up studies.

The universe of Star Wars is set in a fictional galaxy that serves as the primary setting for the Star Wars multimedia and film franchise. Originally established by George Lucas as a "galaxy far, far away", it comprises numerous planets, moons, star systems, and species. The galaxy is divided into four broad sub-regions: the Core Worlds, Mid Rim, Outer Rim, and Unknown Regions. Notable planets include Coruscant, an ecumenopolis in the Core that functions as a political and cultural center, and Tatooine, a desert planet located in the Outer Rim. The universe initially encompassed a collection of works recognized as canon by Lucasfilm as part of the official Star Wars storyline. Subsequent expanded material in other media was later rebranded as the Legends universe by Disney, declaring it non-canonical to the official universe.

Within this fictional body exists a variety of intelligent species, including Humans, Twi’leks, Wookiees, Rodians, and Hutts, as well as several major governing bodies throughout galactic history, such as the Galactic Republic, Galactic Empire, Rebel Alliance, New Republic, and First Order. Each of these entities operates under differing political structures, ranging from democratic institutions to totalitarian regimes. Interstellar travel is facilitated by hyperspace, allowing rapid movement between distant star systems. A central metaphysical concept in the Star Wars universe is the Force, an omnipresent energy field that connects all living things. The Force is divided into two principal aspects: the Light Side, traditionally followed by the Jedi Order, and the Dark Side, embraced by the Sith. The universe also features a high level of technological advancement, including starships, droids, and energy-based weapons such as blasters and lightsabers. The timeline of in-universe events is often measured in reference to the Battle of Yavin, a pivotal conflict depicted in the original 1977 film, serving as a chronological anchor for subsequent developments in the franchise.
