In physics, spacetime is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive where and when events occur.

At speeds approaching the speed of light, objects get shorter and time slows down. This means that space and time are one unified, dynamic thing — space-time.
In physics, spacetime is any mathematical model that combines space and time into a single continuum. It is a mathematical concept used to refer to all points of space and time and their relation to each other. Historically, space and time were thought of as separate entities.
