The reality of a space-time-reality is determined by the dimension of the perspective of a particular time & space.
It is determined by an individual’s particular perspective of here & now.
Every reality has four dimensions that allow a particular physical perspective.
Dimension one is: Linear
This is measured in Length in a direction that is forward/backward, north/south, or longitudinal.
Dimension two is: Lateral
This is measured as Width or Breadth in a direction that is right/left, east/west or latitudinal.
Dimension three is: Vertical
This is measured as Height or Depth in a direction that is up/down, as a peak/trough or as a zenith or nadir.
Dimension four is: Holonic
This is measured in a hierarchy of holons or a holarchy.
The direction of a holarchy is in/out, internal/external or micro/macro.
Even though my focus is directed one dimensionally, the dimension/direction of my perspective, my perception is always four dimensional.
