	Zenon was primarily concerned with the relations of space, time and motion and encountered a number of paradoxes. The best known of these is the paradox of [[Achilles and the tortoise]], according to which the fast Achilles could never catch up with a slow tortoise in a race if he gave it a head start, because before he could reach it, it would already have advanced a little further - and so it goes on and on.

The problem with all of [[w:Zeno's paradoxes|Zeno's paradoxes]] is that he did not yet know how to grasp the concept of infinity. Basically, it is always about the problem of divisibility: is the world an infinitely divisible continuum or are space and time divisible into a finite number of discrete units? To this end, the idea of empty space is also rejected, for if it contains nothing, it is nothing and consequently cannot exist. At about the same time, Leucipp and Democritus held exactly the opposite opinion with their atomism. Since Plato and Aristotle, Zeno's arguments have been refuted. Aristotle, for example, distinguished between infinite extension and infinite divisibility and concluded from this that a finite but infinitely divisible distance could very well be traversed in finite time.

Paradoxically, modern quantum theory tilts the scales back in Zeno's favour in practice. Thus, there is in fact no truly empty space, since within the limits of the Heisenberg uncertainty principle, it is filled with vacuum fluctuations formed by particle-antiparticle pairs that rapidly emerge and immediately decay. In addition, the so-called [[w:quantum Zeno effect|quantum Zeno effect]], which is reminiscent of the [[w:arrow paradox|arrow paradox]] and is based on the fact that the light emission of an excited atom can be stopped by a dense sequence of measurements, was experimentally confirmed at the [[w:Ludwig Maximilian University of Munich|Ludwig Maximilian University of Munich]] in 1994.
