Time and Space
Time and space are fundamental aspects of our universe. Space refers to the three-dimensional area in which objects exist and move—think of it as the stage where everything happens. Time is the ongoing progression of events from the past through the present to the future. They are interconnected in Einstein’s relativity, meaning that objects with mass can curve space and influence the flow of time. Together, space and time form a four-dimensional fabric called spacetime, which describes how the universe behaves and how objects move within it.
