chronon

/ˈkroʊnɑn/
noun
  1. A hypothetical unit of time, the smallest possible discrete interval of time in some theories of physics.
    • Some physicists propose that a chronon is the quantum of time, like a photon is for light.
    • The idea of a chronon challenges our everyday experience of time as smooth and unbroken.
    • In this model, time does not flow continuously but jumps from one chronon to the next.
