Space (in physics)

In physics, space refers to the three-dimensional extent in which objects and events occur. It provides the framework for positions, distances, and directions, allowing us to locate everything around us. Space itself is not empty; it can contain fields, particles, and energy. Modern physics, especially Einstein’s theory of relativity, shows that space is interconnected with time, forming a four-dimensional fabric called spacetime. This fabric can bend and curve due to mass and energy, explaining phenomena like gravity. Essentially, space is the stage on which the universe’s physical processes unfold, shaping how matter and energy interact.
