I may be wrong about the above, maybe when everything outside the supercluster is farther than 130 billion lightyears we will still always have "fossil" light at ever-increasing redshift, almost frozen in time, that shows the observable universe as it was. At some point though the redshift would be too extreme for the signal to be even theoretically observable.

If anyone has seen actual astronomers and cosmologists talk about this I would be delighted to see what they have to say.
