A community portal about Spacetime with blogs, videos, and photos. According to Wikipedia.org: In physics, spacetime is a mathematical model that combines space and time into a single construct called the space-time continuum. Spacetime is usually interpreted as a four-dimensional object with space being three-dimensional and time playing the role of the 4th dimension. According to Euclidean space perception, our universe has three dimensions of space, and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a good deal of physical theory, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.
