Spacetime Coordinates
Spacetime coordinates combine space and time into a single framework used to describe events in the universe. Instead of thinking of time and space separately, spacetime treats them as interconnected dimensions. Each event can be pinpointed using four coordinates: three for location (length, width, height) and one for time. For example, to describe when and where something happens, you would specify its position in three-dimensional space and the time at which it occurs. This concept is essential in physics, particularly in Einstein's theory of relativity, which shows how gravity affects the fabric of spacetime.
