Spacetime
Spacetime Spacetime is a four-dimensional system that is composed of three spatial dimensions and a temporal time dimension. Einstein used the concept of spacetime in…
A mathematical model developed by Hermann Minkowski and used by Albert Einstein in his General Theory of Relativity. Under General Relativity, spacetime consists of three non-Euclidean spatial dimensions and a Lorentzian manifold for the temporal time dimension. Under the Theory of Time, spacetime consists of four Euclidean spatial dimensions (including a Spatial-Time Dimension) and a linear temporal time dimension.
