gravityless
Lacking downward force
Gravityless describes a state or environment without gravitational pull—the weightless condition of objects in space or freefall.
The word appears in science fiction and casual description more than technical writing, where *zero gravity* or *microgravity* are preferred: The astronauts floated through the gravityless chamber.
