far future
Eons from now
The far future is a time vastly removed from the present—centuries, millennia, or even billions of years ahead.
The term appears in science fiction, cosmology, and speculative philosophy when discussing humanity's distant fate, the death of stars, or the ultimate end of the universe.
Unlike the near future, which feels imaginable, the far future exceeds normal planning horizons: In the far future, Earth will be swallowed by the expanding sun.
