Open and closed universe theory
Global structure covers the geometry and the topology of the whole universe—both the observable universe and beyond. While the local geometry does not determine the global geometry completely, it does limit the possibilities, particularly a geometry of a constant curvature. The universe is often taken to be a geodesic manifold, free of topological defects; relaxing either of these complicates the analysis considerably. A global geometry is a local geometry plus a topol… WebAccording to most current cosmological theories, the universe is closed if it is sufficiently dense, and therefore possesses enough gravitational force to stop or reverse the …

WebHis 1917 paper presented a simple model of a closed spherical universe which "from the standpoint of the general theory of relativity lies nearest at hand". In order to arrive at a quasi-static distribution of matter he found it necessary to introduce the "cosmological term" to the field equations (as discussed in Section 5.8), so he based his analysis on the … WebExplains the difference between an Open Universe, Closed Universe, and Flat Universe. Also discusses the expansion of space-time.
WebThe very process of inflation contained the answer. The exponential growth increased the universe’s size by at least a factor of 10 26! This incredible expansion would take the original geometry of the universe (whether closed, flat, or open) and drive it exquisitely close to a flat geometry. This was a hallmark prediction of inflation.
