Space and Distance

Space refers to the vast, three-dimensional expanse in which all objects and events occur, from planets and stars to galaxies. Distance measures how far apart these objects are within that space, often expressed in units like miles or kilometers. Think of space as the universe's stage and distance as the measurement of how far actors (celestial bodies) are from each other within it. Understanding both helps us comprehend the scale of the universe and how objects interact over enormous spans.
