Spacetime is a term used in relatavistic physics to describe the relationship between space and time and how they function within a single continuum. It is often referred to as the Space-Time continuum. Spacetime is usually interpreted with space as a three-dimensional concept and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions. Spacetimes are the arenas in which all physical events take place; an event being a point in spacetime specified by its time and place.
