I've just been reading some of these threads, as i am quite interested in cosmology. I was wondering about a possible cosmology of the universe that i haven't really seem written about anywhere. What if, each point of the universe is both the centre AND edge of the universe? If the Universe had this cosmology, then the universe would look like a singularity at the time of the big bang, and still look like a singularity today even after billions of years of expansion. With this cosmology, if you were to travel in a spaceship in one linear direction fast enough, then you'd eventually arrive back at the point where you started. This also means that all stars in the eastern sky would be 'mirrored' in the western sky, which obviously doesn't happen but that might simply be because the universe is expanding faster than the speed of light. So a universe with this cosmology would have these basic properties: 1)There would be no physical 'boundary' to the universe as each point of the universe is a boundary, like spheres at each point which would be extremely small. 2)You could travel in any direction for an infinite distance, however you would end up back where you started over and over. 3)At any position in the universe you are at both the centre and edge of the universe. 4)The universe would have finite volume overall, and look like a singularity to some 'outside observer' at both the time of the big band and even today after billions of years of expansion. What do the cosmologists among us think? I'm just curious about this and thought i'd start a thread about it. Thanks.
