$2$ m/s. Thus, if we assume that the swimmer is located near the trampoline, and she wants to reach a point located at the center of the pool, say $10$ m away, this will take her $5$ s, if she can travel at the maximum possible speed.

Imagine now a child on the trampoline. In this metaphor the child is a microscopic entity, located outside of the pool’s water, that is, outside the ordinary 3-dimensional physical space. Indeed, microscopic entities, when not organized into macroscopic aggregates, or when not interacting with macroscopic entities, are typically non-spatial entities [@Aerts1998; @Aerts1999; @Sassoli2011; @Sassoli2012; @Sassoli2013; @AertsSassoli2014; @Sassoli2015], not belonging to the water of the pool. The child, as a non-spatial entity, “moves” through another “space,” which in a sense is adherent to our physical space, and which in our metaphor is represented by the layer of air above the pool; and since the viscosity of air is lower than that of water, he will be able to do so with greater effective speed than the swimmer.

Suppose that the limit speed in the air, for the child, is of $10$ m/s, and that he is actually running at that speed on the trampoline,
