Tachyon Map

Primarily associated with faster-than-light speed, communication across vast distances, or interaction with/manipulation of spacetime. Tachyons are a theoretical concept of particles that travel faster than light, and in pop culture, they are almost exclusively used as a scientific explanation for extraordinary feats like FTL travel, instantaneous communication across galaxies, or even directly influencing the fabric of spacetime itself. Fundamentally linked to highly advanced/speculative technology and the pushing of scientific boundaries (often beyond current understanding). Tachyons are firmly in the realm of theoretical physics, making their fictional use inherently tied to technology that must utilize or manipulate these particles, pushing the boundaries of what is currently considered possible. Can be used as a mechanism for time travel, seeing into the past or future, or causing temporal paradoxes. Because traveling faster than light can theoretically violate causality, tachy...

Early Concepts & Relativity (Early 20th Century - 1950s) 1904-1905 : While not explicitly proposing tachyons, Arnold Sommerfeld explores the possibility of entities traveling faster than light in the context of Max Abraham's rigid electron theory, predating Special Relativity. Albert Einstein's theory of Special Relativity establishes the speed of light in vacuum (c) as a universal speed limit for energy and information transfer, seemingly precluding faster-than-light (FTL) particles. Conventional objects require infinite energy to reach c . Post-1905 : Theoretical discussions occasionally touch upon FTL possibilities within relativity, often concluding they lead to causality violations (effects preceding causes in some reference frames). Formal Proposals (1960s) 1962 : Olexa-Myron Bilaniuk, V.K. Deshpande, and E. C. George Sudarshan publish a paper ("Meta-Relativity") re-examining Special Relativity and proposing the theoretical possibility of particles that ...
