Understanding Space: A Fundamental Concept in Physics and Philosophy

Space is the three-dimensional expanse in which all objects and events have relative position and direction. While classical physics viewed space as a fixed, empty container, modern physics, particularly <a href="/article/albert-einstein">Albert Einstein's</a> theory of relativity, describes it as a dynamic part of a four-dimensional continuum called spacetime, which can be curved by mass and energy. Philosophers have long debated whether space is an independent entity, a relationship between objects, or a fundamental aspect of human perception.
