Zero g 零重力

Zero gravity was coined by Arthur C. Clarke in Sands of Mars, his first science-fiction novel. A year later, he coined the term zero g, where g is short for "gravity," in his novel Islands in the Sky. This concept of zero g became official terminology of astronauts as the Space Race accelerated in the 1960s, and today, it's viewed more as a science term than a sci-fi term.

亚瑟·C·克拉克在他的首部科幻小说《火星之沙》之中创造了零重力这个词。一年后，他又在小说《空中列岛》中创造了零重力的缩写Zero g。1960年代，太空竞赛加速，零重力的概念成为了宇航员的官方术语。如今，它更多地被看作是科学术语而非科幻术语了。
