final frontier
The unknown beyond
Final frontier refers to the last unexplored territory or the ultimate challenge yet to be conquered.
Space is often called the final frontier, popularized by Star Trek's opening narration.
The phrase applies to any domain representing humanity's next great undertaking: The ocean floor remains Earth's final frontier.
It carries romantic connotations of adventure and discovery.
