My question is: since tha Big Bang Theory predicts a starting point to the Universe, is there a maximium limit to the distance of a galaxy that can be observed??
If modern cosmologists are right, the red-shift gradient of light from galaxies decreases exponentially as it approaches the "age-of-the-universe." As you approach distances that correspond to the "birth of the universe," you need higher and higher degrees of red-shift to indicate a given fixed increase in distance. We can conveniently never observe the age-of-the-universe distance, because the red-shift would need to be infinite (eg.there is no "wave" left in the light wave).
What of the even simpler question "how was age-of-the-universe fixed?" Here's the Subaru Observatory:
"What distance a redshift corresponds to depends on the overall structure of the universe." ... and that, unfortunately, is something that is not known. That's why we're looking at these galaxies in the first place.

This is too simple to be right, but.. ah well never mind.
I think we'd all prefer simplicity to a despairing combination of mostly dark matter, dark energy, and least significantly, observable matter and energy that's not doing what it's supposed to do. Let's go to the Meta Model.
