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.

亞瑟·C·克拉克在他的首部科幻小說《火星之沙》之中創造了零重力這個詞。一年后，他又在小說《空中列島》中創造了零重力的縮寫Zero g。1960年代，太空競賽加速，零重力的概念成為了宇航員的官方術語。如今，它更多地被看作是科學術語而非科幻術語了。
