Abstraction vs. Physicality: The Nature of Space and Dimensions:

April 02, 2025

Space is an abstract concept; it lacks intrinsic physical properties. For instance, length itself has no inherent attributes—it is merely a one-dimensional extension that defines the direction in which the length of a physical object is measured. It does not exist as a measurable entity on its own but serves as a reference for measurement.

Similarly, height, depth, and time function as conceptual tools rather than physical entities. Time, for example, is not a tangible substance but a mental framework that allows us to perceive and understand change. The combination of spatial dimensions—length, height, and depth—provides meaning to physical transformations, yet these dimensions do not possess physical properties in and of themselves. Unlike tangible objects, they do not have independent existence; rather, they serve as abstract references that facilitate the measurement and comprehension of physical reality.
