Technology in science fiction

 Technology in science fiction examines the possibilities 

 

the insinuation of new technological concepts. The authors have taken, or created, new alteration and technologies, and worked out what they could be and how they could be used. This tradeoff goes both ways: sometimes technology comes first in science fiction, then becomes reality (like space travel), and other times real technology comes first, and science fiction authors speculate on how. it could be used and how it could affect the human condition. Similarly, the accuracy of the technology draw spans a wide range: sometimes it's existing technology, sometimes it's a physically realistic representation of distant technology, and sometimes it's just a raster device that looks scientific but has no base in Science. Examples are drawn from space travel in science fiction involve:

Realistic case: Spacesuits. They are almost always based on existing suits or a short-term extrapolation of their capabilities.

Extrapolation: Travel within the Solar System. As of 2019, humans have only traveled in Earth orbit or from Earth to the Moon and vice versa. However, traveling within the Solar System does not violate physical principles. Scribing Device: Drive faster than light. It is not backed by physics as we know it, but it is necessary for galactic or intergalactic plots with human lifespan.

Dummy technologies that have been made since then

Almost all the new technologies that become practical were previously used in science fiction. The following are some examples, from a very large set: The transparent aluminum that appears in the Star Trek universe has since become a reality [1] as Aluminum Oxynitride (ALON ™), patented in 1985, [2] and as different from metallic aluminum as iron oxide. Instead of being used as transparent blast shielding as in fictional Enterprise-class starships, this transparent ceramic is used, as chemically similar (and similarly expensive) corundum (crystalline aluminum oxide) has been used for a long time, in sturdy windows.

Tractor/repulsor beams have been made as laser-based optical tweezers, [3] and more recently as a pair of Bessel beams. [4] These instruments use radiation from the laser beam to manipulate microscopic particles in what is called an "optical trap" [4] along the beam as desired. [4]

Fictional tractor beams have been used prominently in the Star

 Wars universe and in the Star Trek universe. In one of the first scenes of Star Wars: A New Hope, a large spaceship uses a beam of this type to take over a small one, in order to capture the protagonists.

Artificial vision / Eye prostheses The visual prosthesis has been a subject of experimentation since the end of the 20th century. Notable characters who use machine vision include all characters from the Ghost in the Shell series who use prosthetic bodies, e.g. Eg Batou's ranger eyes, Saito's left eye, and Motoko Kusanagi's artificial eyes, Geordi La Forge from the Star Trek: The Next Generation series who made use of a VISOR and later; Eye implants, RoboCop from the RoboCop series, Spike Spiegel from the Cowboy Bebop anime series and Illusive Man from the Mass Effect video game series.

Cell Phones, the Star Trek science-fiction franchise, introduced the wireless communication device that has since become the cell phone. [5] The real idea of small and portable phones dates back decades before this. Science fiction author Robert A. Heinlein in his 1948 book Space Cadet, had a young man named Matt reach into his bag, pull out his phone, and answer to speak to his father, and a young man answering a phone call on his horse in Heinlein's 1961 book Between Planets. [6]

Tricorder The Lab-On-a-Chip (LOCAD-PTS) Portable Application Development Test System used by astronauts on the International Space Station is specifically designed for biochemical molecules for the purpose of "identifying microbes in-station services. spatial "by using the Gram staining method. 

Although less advanced than the fictional tricorder from the Star Trek series, the LOCAD-PTS is useful for rapidly identifying bacteria and fungi on the International Space Station without having to send samples back to Earth,  thus running the risk of contamination or degradation.  Fungi have proven to be a hazard if left unchecked on the space station, as they managed to break down some Russian electronic components. 

The Tricorder featured in the Star Trek universe was capable of measuring almost anything, from the chemical composition of explosives to the signs of life of a dying humanoid. The LOCAD-PTS does not yet distinguish between live and dead test material.

Communication

Communication has often been advanced to a greater technological range in science fiction, usually with the idea of being able to see the person or place you are trying to communicate, or make a call or speak to someone in a more convenient way. A basic science fiction technology is phones or screens that allow you to see the live feed of the person you were talking to while making a call. This was used in a lot of early science fiction before the concept was actually realized. It was used as a futuristic type of content device for people to gather from long distances in Stanley Kubrick's film [[2001: A Space Odyssey (film), while in George Orwell's 1984 (novel) it was used as a form for the socialist Ingsoc to directly control and command the citizens of the dystopian future imagined in history.

Holograms are the idea of being able to talk to someone by communicating with a three-dimensional light projection of their image. While it appears in many different sci-fi sources, it is used most prominently in the Star Wars franchise (franchisee) to speak to someone face-to-face and tell lectures from long distances in the Marvel Cinematic Universe.

Another type of contact involves the use of androids controlled by other people, giving them the ability to actually interact with objects and people from long distances. This was most popularly seen in the thriller Surrogates, which is set in a future where this type of interaction is so common that people have forgotten what it's like to have social exchanges external of an android body. In real-world science, signals take time to travel through space. However, in Orson Scott Card's Ender's Game, a solution for this is on condition that in the form of a video screen that allows people to talk to each other instantly in space no matter how far away they are, effectively messaging faster. then the speed of light.

Sometimes in science fiction, it is not space that intersects with advanced communication, but time. The mystery film Don’t Let Go (film) has an example of this when a father discovers that his phone has the ability to call his daughter in the past and uses it to prevent her death. A similar event occurs in the drama film Frequency (2000 film), where a solar storm temporarily gives a police officer's radio the ability to speak to people 30 years ago, which he uses to save his father but causes a fatal wave in history both must work together to solve it.
