Space refers to the boundless three-dimensional extent in which objects and events have relative position and direction. It's where everything exists and moves. Space can be thought of as the canvas on which the universe paints its picture🎨. It's not just empty void; space itself can be warped and curved by gravity, as Einstein showed. Unlike time, which progresses, space is often thought of as static, but it is, in reality, expanding. Consider outer space and the rooms in your house—both are volumes filled with existence.
