The idiom "light years away" originates from the field of astronomy and astrophysics, where a "light-year" is used as a unit of measurement for astronomical distances. It represents the distance that light travels in one year, approximately 5.88 trillion miles. However, in everyday language, the idiom has evolved figuratively to convey a significant difference or vast distance between two things, concepts, or points of comparison, unrelated to actual astronomical distances. It is now commonly used in conversations, discussions, or writing when people want to highlight the vastness of the contrast between two elements.
