Like Riemann, he wanted a closed universe (one whose volume and circumference were perfectly finite and measurable) without a boundary he also chose the hypersphere to model the spatial part of the Universe. In 1917, Einstein presented the first relativistic model for the universe. The curvature is connected to the density of matter. The non-Euclidean character of the Universe appeared from then on not as a strangeness, but on the contrary as a physical necessity for taking account of gravitational effects. It is in fact the curvature of space-time as a whole which allows one to correctly model gravity, and not only the curvature of space, such as Clifford had hoped. Image by © Hulton-Deutsch, Collection/CORBIS Albert Einstein (here in 1910) developed the theory of relativity and was awarded the 1921 Nobel prize for physics. In this theory, the Universe does not reduce to a space and a time which are absolute and separate it is made up of the union of space and time into a four dimensional geometry, which is curved by the presence of matter.
