relative space ?
space means space that is defined by relative
units are units, whose magnitude may vary in different locations
we define space using units like miles or meters. we assume that (at least
in daily life) a meter is the same everywhere in space. in principle,
instead of meters of course we can also use any other kinds of units,
however, many units vary in magnitude through space. they are relative
units. the space defined by these relative units is called relative space.
Why would one do this? this makes a lot of sense when we want to capture
the subjective qualities of space. Since we cannot perceive absolute distances
directly, we have to use different cues to measure space.
