Web17. apr 2024 · If the universe is flat ( k = 0) then the spatial part of universe has the topology of R 3, but the topology of a closed universe is a 3-sphere S 3. Now, since we have good reasons to think that our universe is pretty flat, why is that not an argument for the universe being exactly flat? As in exactly k = 0. WebIn this system the entire universe was part of a great sphere. This sphere was split into two sections, an outer celestial realm and an inner terrestrial one. The dividing line between the two was the orbit of the moon. While …
