arrow paradox

noun1

1. •
   One of Zeno's paradoxes, dealing with the apparent impossibility of an arrow flying through space: if everything when it occupies an equal space is at rest at that instant of time, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless at that instant of time and at the next instant of time, but if both instants of time are taken as the same instant or continuous instant of time then it is in motion.
