WebNov 14, 2024 · The only way we can tell whether spacetime has an inherent curvature or not is by observation. One of the terms allowed in the Einstein equation is a cosmological constant, normally written as Λ. If Λ is non-zero then spacetime has a scalar curvature (the Ricci scalar) given by: R = 4 Λ WebIf the Universe is 'just right', it will expand for a long while, and then slow to a stop, and the Universe will remain at that density forever.

The curvature is a quantity describing how the geometry of a space differs locally from the one of the flat space.
