I heard recently that the universe is thought now to only be 7-12 billion years old - based on Hubble obsevations of Cephied varibles. If this is true how can we see objects 15 billion light years away (I assume you are talking about quasars) - in essence how can a child be older than its mother.

Thanks for the comment on space it was helpful. What you are saying, if I understand correctly, is that space is infinite and only the matter is expanding outward. If I have misunderstood please correct me. I thought space and time moved along in a "linear" fashion with the expanse of matter.
