Emergence definition

A light year emerges as the distance light travels in one year, requiring an understanding of light's properties, which is a measure of energy and wave, and serving as a standard unit of interstellar distance measurement, built upon the concept of standard, which is a model or pattern used for comparison or measurement in a spatial context.
