WebApr 26, 2024 · The results have shown to a high degree of accuracy that the density of the Universe is such that it expands in every direction without any positive or negative curvature, in other words, the Universe is ‘flat’. This flat Universe is a major component of the standard cosmological model. WebDec 15, 2024 · A flat universe is exactly in between these two cases: parallel paths stay at the same distance and never cross. We characterize the curvature with parameter Ω k. Using the sign convention of the authors of today’s paper, a negative Ω k indicates a closed universe, a positive Ω k an open one. If the universe is flat, Ω k is exactly zero.
