The hypothetical particles tachyons, defined through being faster than light, have inspired many occurrences in fiction. [1] [2] In general, tachyons are a standby mechanism upon which many science fiction authors rely to establish faster-than-light communication, with or without reference to causality issues, [3] [4] as well as a means to achieve faster-than-light travel. [4]
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
Science fiction (sometimes shortened to sci-fi or abbreviated SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life.
Force fields are vital for surviving any battle in the fictional world, but what exactly are force fields? In science fiction force fields are very straight forward, but to make a repulsive force does appear impossible to make in a lab. Gravity appears in the four force list in Kaku's book. Gravity acts as the exact opposite of a force field ...
Ursula K. Le Guin first used the word ansible in her 1966 novel Rocannon's World. [1] [4] Etymologically, the word was a contraction of answerable, as the device allowed its users to receive answers to their messages in a reasonable amount of time, even over interstellar distances.
"A science fiction story is a story built around human beings, with a human problem, and a human solution, which would not have happened at all without its scientific content." [13] Basil Davenport. 1955. "Science fiction is fiction based upon some imagined development of science, or upon the extrapolation of a tendency in society." [14] Edmund ...
Space warfare is a main theme and central setting of science fiction that can trace its roots back to classical times, and to the "future war" novels of the 19th century. . With the modern age, directly with franchises as Star Wars and Star Trek, it is considered one of the most popular general sub-genres and themes of science fiction
The problem of a material object exceeding light speed is that an infinite amount of kinetic energy would be required to travel at exactly the speed of light. Warp drives are one of the science-fiction tropes that serve to circumvent this limitation in fiction to facilitate stories set at galactic scales. [11]
