WebAug 8, 2014 · Mass also has an effect on the overall geometry of the universe. The density of matter and energy in the universe determines whether the universe is open, closed, or flat. If the density is equal to the critical density, then the universe has zero curvature; it is flat. You can imagine a flat universe like a sheet of paper that extends ... WebThis "flat" Universe is about the Universe of all space-time, not just the physical, tangible visible universe of stars (natural fusion reactors) or star groups (galaxies). This link below is a description of the "flat" universe meaning all of space-time, the visible, physical universe is only a tiny dot on this geometry.
