Etymology[edit]

super- +‎ luminal

Adjective[edit]

superluminal (comparative more superluminal, superlative most superluminal)

  1. (astronomy, science fiction, fantasy) Faster than light; having a speed greater than light.
    • 1984, Edward Edelson, "Faster than light?," Popular Science, p. 70 (retrieved 20 Nov 2013):
      The first thing to understand about superluminal expansion is that it isn't visible to the unaided eye. The objects that appear to be moving faster than light are emitting radio waves, not visible light.
