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.

The total center of mass of the forks, cork, and toothpick is on top of the pen's tip. Significant aspects of the motion of an extended body can be understood by imagining the mass of that body concentrated to a single point, known as the center of mass. The location of a body's center of mass depends upon how that body's material is distributed.
If a first body of mass m A is placed at a distance r (center of mass to center of mass) from a second body of mass m B, each body is subject to an attractive force F g = Gm A m B /r 2, where G = 6.67 × 10 −11 N⋅kg −2 ⋅m 2 is the "universal gravitational constant". This is sometimes referred to as gravitational mass.
The Metamorphosis by Franz Kafka. While we're riffing on sci-fi a bit, we might go into the surreal. Kafka's The Metamorphosis resists most categorization, but its absurd and impossible conceit ...
American science fiction author and editor Lester del Rey wrote, "Even the devoted aficionado or fan—has a hard time trying to explain what science fiction is," and the lack of a "full satisfactory definition" is because "there are no easily delineated limits to science fiction." [3] Another definition comes from The Literature Book by DK and ...
