I mean since there is nothing outside of space and no dimensions the shape would not exist would it? http://en.wikipedia.org/wiki/Image:CMB_Timeline75.jpg We use light to see our universe. So say a star is 1000 light year away then we can see it what it was 1000 years Back. Age of Starts is arround 9 Billion years. So when we see thing 100 Billion light years away. If a star was present there then It is dead after 9 Billion years. So Any Star we see outside 9 Billion years away are not present and do not exist. It may happen some star has born 5 Billion years back at a distance of 15 Billion light year away. So it will take another 10 Billion years for light to reach us from that star. So talking about any Galaxy/ Star which is away from 9 Billion years is meaningless as there are high Chances that it do not exists now. Since we cannot see Whole Universe at a single time we can never say its correct shape. As our Shape will be having time lapse. The far away Stars have already died. And there may be many stars which exist and there light have not reach us. I am not an Astronmer So I do not exactly know how such things are predicted. Anyone have some clue how these things are considered? Bye Sanny- Hide quoted text - - Show quoted text - 4 dimensional round hypersphere. Try again, if that happens it happens in space, and outside the universe there is no space unless there is other or multiple universes, which have less than nothing between them where hyper can't happen. In string theory though graviton string shapes can travel between universes. Mitch Raemsch- Hide quoted text - - Show quoted text - |

The closed universe described by Einstein happens to be a 4Sphere or 4 dimensional hypersphere surface. |
