Galaxies that are very far away can effectively be traveling faster than the speed of light (space-time expansion rate is faster than the speed of light). Big bang inflation theory also has the Universe expanding at faster than the speed of light.
Perhaps you need to explain why the
age* of the Universe should be equal to its size?
(lucky the Theory of relativity places a speed limit of "c" only on Baryonic Objects (and mass-less photons) existing in regular space-time. Space-time itself is not limited to the speed of light. After all, what is the mass of space-time? I get confused at the various estimates of the TOTAL size of the Universe when compared to the Observable size of the Universe, Some estimates predict the Universe to be 12 billion times greater than the observable Universe. The way things are heading, eventually the observable Universe will be so small that the night sky will be absent of stars and galaxies. Not that any humans will be around to witness this collective decay into infinite madness
