There is no discretion between a space and those that are included within its limits.
Since the empty shapes have the same plastic values like the filled ones.
An empty space is affected by its cocoon (surrounding) and its content.
Accordingly is affecting the behavior of the material that moves inside it.
Something might look foggy and clouded but includes a shape. It may look
Chaotic but it has a substance.
