So we haven't seen anything further out than these most distant objects, and they all have that receding redshift indicative of being sourced from the central big bang.

The big bang theory and the expanding universe may be strong possibilities given the research and what we know. But does current technology prevent us from seeing out farther than we do now? Could it even be possible to discover galaxies 100 billion or more light years away? This is why I'm skeptical of any claims to age, because there's so much out there we don't know yet.

There are two articles on yesterday's thread.

"Galaxy clusters consist of thousands of galaxies gravitationally bound into huge structures," said Joseph Mohr, a professor of astronomy at the University of Illinois. "Because of the expansion of the universe, the clusters appear denser at larger redshifts, when the universe was younger and denser."

and from the other article . . .

Inside a gravastar, space-time would be "totally warped," the researchers say. Further, the inner space would exert an outward force, which would enhance the durability of the bubble

and . . .

Mottola and Mazur have taken their extreme idea to a mentally dizzying new level: The say our entire universe may be the interior of a giant gravastar.

For some reason these two articles together got my brain lobes flapping.

Could it even be possible to discover galaxies 100 billion or more light years away?

I's possible, yes. But two preconditions would have to be met: (1) such galaxies would have had to exist 100 billion years ago; because (2) the universe would have to be at least 100 billion years old, so that the light from such galaxies would have had time to get to us.

Well yes. That's why they publish reports and continue looking for new discoveries. Otherwise we would arbitrarily decide that the universe is 13.6789023 billion years old and leave it at that, shoot disenters.
