Spacetime is a fundamental concept in physics that combines the three dimensions of space with the dimension of time into a single four-dimensional continuum. This concept, introduced by Albert Einstein in his theory of relativity, revolutionized our understanding of the universe. In spacetime, the positions of events are described not just by three spatial coordinates (such as length, width, and height) but also by a time coordinate. This merging of space and time shows that they are interwoven and relative, meaning that the measurement of time can change depending on the velocity of the observer and the gravitational field they are in. This framework helps explain phenomena such as the warping of spacetime by massive objects, which we perceive as gravity.
