-
We live our lives in three dimensions for our threescore and ten allotted years. Yet every branch of contemporary science, from statistics to cosmology, alludes to processes that operate on scales outside of human experience: the millisecond and the nanometer, the eon and the light-year.

-
- (only in the plural, informal, figurative) A very long way.
- (only in the plural, informal, figurative) A very long time.
使用する際の注意点
- The light year is a unit of length, but because it contains the word year, it is sometimes assumed to be a unit of time. Its use in the figurative sense of "a very long time" is nonstandard; it is preferable to use an alternative term in this case.
- light year and light-year are similarly common overall, lightyear lagging far behind. light-year leads in the American corpus while light year leads in the British corpus. GPO manual favors light-year. Merriam-Webster has light-year. OED has light year.
