Category: Space

Space refers to the vast, seemingly infinite expanse that exists beyond the Earth’s atmosphere, encompassing all celestial bodies, such as stars, planets, moons, asteroids, and galaxies. It is characterized by a near vacuum, where matter is sparse and where physical laws of physics operate differently compared to Earth’s surface. In a broader sense, space also refers to the three-dimensional extent in which objects and events occur and have relative position and direction in the universe. In various contexts, space can denote physical distance, as well as conceptual dimensions like personal space or abstract spaces in mathematics. In the context of astronomy, space is often studied to understand the origins and evolution of the universe, cosmic phenomena, and the potential for extraterrestrial life.
