Superstrings

Part of speech: noun

Definitions

  1. Hypothetical one-dimensional fundamental components proposed in theoretical physics to explain all particles and forces, conjectured to vibrate at different frequencies ; elongated and minuscule constructs posited to unify quantum mechanics and gravity ; basic elements in string theory representing the smallest possible units of matter and energy, envisioned as tiny threads whose vibrations determine particle properties
  2. Theoretical infinitesimal filaments suggested as the ultimate building blocks of the universe encompassing all matter and forces through their vibrational modes ; dimensionally tiny strings postulated in advanced physics to reconcile various fundamental interactions ; minute strands considered foundational in the framework that attempts to unify physics via vibrating energy loops
  3. Objects theorized to be extremely small and extended in one spatial dimension, which underpin a modern physics model seeking to explain fundamental phenomena ; conceptual linear entities used in a unifying model of particle physics and cosmology ; tiny string-like structures envisaged as the core constituents in theories aiming to blend quantum field theory and general relativity

Etymology: "Superstrings" is simply the plural of "superstring," a noun from the physics term "superstring theory," which is shorthand for "supersymmetric string theory." Supersymmetry is a proposed symmetry linking the two broad classes of particles, matter particles and force-carrying particles, and string theory models those particles as tiny one-dimensional vibrating filaments rather than points. Joining the two ideas produced the compound "super" plus "string." The word was therefore not built directly from its parts in everyday use. Physicists first named the theory, and the shorter noun was then pulled out of that longer name, a process called back-formation. Writers and students meeting the phrase "superstring theory" could drop the "theory" and speak of the strings themselves, which is how the plural came to describe the hypothetical objects that the theory proposes.

Synonyms: string theory strings, fundamental strings, strings
