Computronium is a material hypothesized by Norman Margolus and Tommaso Toffoli of MIT in 1991 to be used as "programmable matter", a substrate for computer modeling of virtually any real object. [1]
It also refers to an arrangement of matter that is the best possible form of computing device for that amount of matter. [2] In this context, the term can refer both to a theoretically perfect arrangement of hypothetical materials that would have been developed using nanotechnology at the molecular, atomic, or subatomic level (in which case this interpretation of computronium could be unobtainium [3] [4] ), and to the best possible achievable form using currently available and used computational materials.
According to the Barrow scale, a modified variant of the Kardashev scale created by British physicist John D. Barrow, which is intended to categorize the development stage of extraterrestrial civilizations, it would be conceivable that advanced civilizations do not claim more and more space and resources, but optimize their already available space increasingly, for example by building a matrioshka brain consisting of several layers of computronium around their star. [5]
In the 2010 film The Singularity Is Near: A True Story About the Future , American futurist Ray Kurzweil discusses a universe filled with computronium. [6] He believes this could be possible as early as the late 22nd century and would be accomplished by sending intelligent nanobots through the universe faster than light, e.g. by using wormholes. [6] According to him, such an endeavor would have the potential to prevent the natural ending of the universe. [6]
In addition, the term computronium is used in connection with science fiction narratives. [7]
A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its solar power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Because only a tiny fraction of a star's energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy.
Kim Eric Drexler is an American engineer best known for introducing molecular nanotechnology (MNT), and his studies of its potential from the 1970s and 1980s. His 1991 doctoral thesis at Massachusetts Institute of Technology (MIT) was revised and published as the book Nanosystems: Molecular Machinery Manufacturing and Computation (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992. He has been called the "godfather of nanotechnology".
Posthumanism or post-humanism is an idea in continental philosophy and critical theory responding to the presence of anthropocentrism in 21st-century thought. Posthumanization comprises "those processes by which a society comes to include members other than 'natural' biological human beings who, in one way or another, contribute to the structures, dynamics, or meaning of the society."
Transhumanism is a philosophical and intellectual movement that advocates the enhancement of the human condition by developing and making widely available sophisticated technologies that can greatly enhance longevity, cognition, and well-being.
The Kardashev scale is a method of measuring a civilization's level of technological advancement based on the amount of energy it is capable of harnessing and using. The measure was proposed by Soviet astronomer Nikolai Kardashev (1932–2019) in 1964 and was named after him.
The Omega Point is a theorized future event in which the entirety of the universe spirals toward a final point of unification. The term was invented by the French Jesuit Catholic priest Pierre Teilhard de Chardin (1881–1955). Teilhard argued that the Omega Point resembles the Christian Logos, namely Christ, who draws all things into himself, who in the words of the Nicene Creed, is "God from God", "Light from Light", "True God from True God", and "through him all things were made". In the Book of Revelation, Christ describes himself three times as "the Alpha and the Omega, the beginning and the end". Several decades after Teilhard's death, the idea of the Omega Point was expanded upon in the writings of John David Garcia (1971), Paolo Soleri (1981), Frank Tipler (1994), and David Deutsch (1997).
The term superhuman refers to humans, human-like beings or beings with qualities and abilities that exceed those naturally found in humans. These qualities may be acquired through natural ability, self-actualization or technological aids. The related concept of a super race refers to an entire category of beings with the same or varying superhuman characteristics, created from present-day human beings by deploying various means such as eugenics, euthenics, genetic engineering, nanotechnology, and/or brain–computer interfacing to accelerate the process of human evolution.
Orion's Arm is a multi-authored online science fiction world-building project, first established in 2000 by M. Alan Kazlev, Donna Malcolm Hirsekorn, Bernd Helfert and Anders Sandberg and further co-authored by many people since. Anyone can contribute articles, stories, artwork, or music to the website. A large mailing list exists, in which members debate aspects of the world they are creating, discussing additions, modifications, issues arising, and work to be done.
A matrioshka brain is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011). It is an example of a class-B stellar engine, employing the entire energy output of a star to drive computer systems. This concept derives its name from the nesting Russian matryoshka dolls. The concept was deployed by Bradbury in the anthology Year Million: Science at the Far Edge of Knowledge.
The Singularity Is Near: When Humans Transcend Biology is a 2005 non-fiction book about artificial intelligence and the future of humanity by inventor and futurist Ray Kurzweil.
Megascale engineering is a form of exploratory engineering concerned with the construction of structures on an enormous scale. Typically these structures are at least 1,000 km (620 mi) in length—in other words, at least one megameter, hence the name. Such large-scale structures are termed megastructures.
The limits of computation are governed by a number of different factors. In particular, there are several physical and practical limits to the amount of computation or data storage that can be performed with a given amount of mass, volume, or energy.
Many of the tropes of science fiction can be viewed as similar to the goals of transhumanism. Science fiction literature contains many positive depictions of technologically enhanced human life, occasionally set in utopian societies. However, science fiction's depictions of technologically enhanced humans or other posthuman beings frequently come with a cautionary twist. The more pessimistic scenarios include many dystopian tales of human bioengineering gone wrong.
The Xeelee Sequence is a series of hard science fiction novels, novellas, and short stories written by British science fiction author Stephen Baxter. The series spans billions of years of fictional history, centering on humanity's future expansion into the universe, its intergalactic war with an enigmatic and supremely powerful Kardashev Type V alien civilization called the Xeelee, and the Xeelee's own cosmos-spanning war with dark matter entities called Photino Birds. The series features many other species and civilizations that play a prominent role, including the Squeem, the Qax, and the Silver Ghosts. Several stories in the Sequence also deal with humans and posthumans living in extreme conditions, such as at the heart of a neutron star (Flux), in a separate universe with considerably stronger gravity (Raft), and within eusocial hive societies (Coalescent).
Perfect Imperfection: First third of progress is a science fiction novel published in 2004 by the Polish science fiction writer Jacek Dukaj, ostensibly as the first part of a planned trilogy. It was published in Poland by Wydawnictwo Literackie.
The simulation hypothesis proposes that what humans experience as the world is actually a simulated reality, such as a computer simulation in which humans themselves are constructs. There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing.
Posthuman or post-human is a concept originating in the fields of science fiction, futurology, contemporary art, and philosophy that means a person or entity that exists in a state beyond being human. The concept aims at addressing a variety of questions, including ethics and justice, language and trans-species communication, social systems, and the intellectual aspirations of interdisciplinarity.
Engineering on an astronomical scale, or astronomical engineering, i.e., engineering involving operations with whole astronomical objects, is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering.
Transhumanist politics constitutes a group of political ideologies that generally express the belief in improving human individuals through science and technology. Specific topics include space migration, and cryogenic suspension. It is considered the opposing ideal to the concept of bioconservatism, as Transhumanist politics argue for the use of all technology to enhance human individuals.
A planetary civilization or global civilization is a civilization of Type I on the Kardashev scale. This type of civilization is likely to be reliant on renewable energy sources such as stellar power, as well as powerful non-renewable sources such as nuclear fusion. A Type I civilization's energy consumption level is roughly equivalent to the solar insolation on Earth (between 1016 and 1017 watts) – around 3 orders of magnitude higher than that of contemporary humanity (around 2×1013 as of 2020).
