I've recently read that the universe is now estimated to be about 95 billion light years in diameter. This was based on what we now can observe (Hubble Deep Field for example), what is estimated to be seen with new technology (James Webb) and an estimate of what's beyond that which we can't yet image. That being said, doesn't the word "diameter" imply a physical center? I've read many of the threads about how there is NO center to the universe as we now understand it, and then I read a description of the SIZE of the universe implying a physical shape with the normal attributes of shapes about which we are familiar. And then I get completely confused. Furthermore, the latest graphic images that depict the arrangement of local groups, clusters and super clusters again show a universe that is physical with a definable center. Could someone please help me grasp this apparent inconsistency? And that's not even getting into when we do visualize the extremes of our universe, what's beyond that edge.
