Space

Space refers to the vast, seemingly infinite expanse that exists beyond the Earth and its atmosphere. It encompasses all celestial bodies, including stars, planets, moons, asteroids, comets, and galaxies, as well as the empty regions between them. Space is characterized by its vacuum, which lacks air and matter, leading to a near absence of pressure and temperature variations. This environment allows for the free movement of objects and phenomena such as cosmic radiation and gravitational forces. The study of space is a key aspect of astronomy and astrophysics, which seek to understand the universe’s origins, structure, and dynamics. In addition to its physical aspects, space can also refer to the conceptual or abstract dimensions in various fields, including mathematics and philosophy, where it may denote areas of influence, range, or capacity.
