WebAug 8, 2014 · A universe with density greater than the critical density has positive curvature, creating a closed universe that can be imagined like the surface of a sphere. And if the universe’s density is less than the critical density, then the universe is open and has negative curvature, like the surface of a saddle. WebEinstein's static universe is closed (i.e. has hyperspherical topology and positive spatial curvature), and contains uniform dust and a positive cosmological constant with value precisely , where is Newtonian gravitational constant, is the energy density of the matter in the universe and is the speed of light.
WebSep 1, 2024 · Open, Flat or Closed? The shape of the Universe is finely balanced between two forces: a) the momentum of expansion and b) the pull of gravity. The strength of this gravity depends on the density and pressure of the matter contained within the Universe. The ultimate fate of the Universe, therefore, depends on how much mass it contains. http://www.opencourse.info/astronomy/introduction/35.universe_structure/
