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. WebOther articles where open universe is discussed: cosmology: Friedmann-Lemaître models: …as negatively curved spaces (“open” universes).
