One such possibility for detection concerns the following curious phenomenon. Take the differential equation, \(df/dx = ax(1 - x)\). It is a straightforward exercise to solve it and one will find a very neat continuous solution, whereas if one takes for the discrete case the corresponding difference equation, \(\Delta f/\Delta x = ax(1 - x)\), depending on the value of the parameter \(a\), the behaviour of the function \(f\) produces chaotic effects, which are absent in the continuous case. See Van Bendegem (2000) and Welti (1987: 516–518). The outcome of such an experiment would not be as clear-cut as wished for, but to observe chaotic effects means that space is discrete, whereas to observe no chaotic effects means that either space is continuous or the hodons are far smaller than we imagined. No further progress is to be reported at the present moment.
