the nature of space

Space is the vast, seemingly empty expanse that exists beyond Earth's atmosphere, extending throughout the universe. It contains celestial bodies like stars, planets, and galaxies, and is governed by physical laws such as gravity. Unlike our terrestrial environment, space is a near vacuum, meaning it has very little matter and virtually no air. Time and space are intertwined in the concept of spacetime, where massive objects can curve space around them, affecting the movement of other bodies. Ultimately, space is both a backdrop for cosmic events and an arena for our exploration of the universe's mysteries.
