History of Space in Timeline
Space is a fundamental concept in physics, representing a three-dimensional continuum with positions and directions. In modern physics, space is often combined with time to form four-dimensional spacetime. Philosophically, the nature of space is debated, with views ranging from it being an entity in itself to a relationship between entities, or a part of a conceptual framework. Understanding space is considered crucial for comprehending the physical universe.
