Macroscopic means measurable and observable by the naked eye;
describes existence as we perceive it.
For instance, a macroscopic view of a ball is just that: a ball. A microscopic view could reveal a thick round skin seemingly composed entirely of puckered cracks and fissures;
or further down in scale, a collection of molecules in the rough shape of a
sphere.
In physics, macroscopy is usually taken relative to what one is observing. If one
looks at galaxy, a star is a macroscopic entity,
even if it's many, many orders of magnitude larger than the
aforementioned ball.
