Outer space, defined as the near-vacuum beyond Earth's atmosphere and between celestial bodies, has long captivated humanity. Scientifically, it is a domain of extreme cold, sparse matter, and cosmic radiation, yet its vastness has inspired literary exploration. Authors like H.G. Wells depicted its abyssal darkness as a frontier of infinite stars, while Edmond Hamilton framed it as an endless void brimming with galactic splendor.
Maurice Leblanc compared Earth to the "bottom of an atmospheric ocean," highlighting humanity's vulnerability in this expanse. These varied portrayals—from scientific awe to existential contemplation—underscore outer space's dual role as both a physical reality and a symbol of the unknown.
