space

Space is the expanding, infinite and empty part of the universe. Space includes stars, galaxies, planets, asteroids, black holes, gas clouds, and various other astronomical objects. The structure and behavior of the universe is studied by astronomy, a branch of science that deals with topics such as the laws of physics and cosmology.

Space is largely a vacuum environment, meaning that most of the matter and energy resides in vacuum. Therefore, space is often thought of as a concept that represents space. Space expands into spacetime, a four-dimensional structure in which time and space are interconnected.

Space is a major area of ​​exploration and research for scientists, astronomers and space explorers. The nature of space is investigated using a variety of scientific theories and observations to understand fundamental questions such as the origin, expansion, and future of the universe. Space has provided much important information and data that has contributed to humanity's discoveries and understanding.
