How can superclusters of galaxies exist beyond the limits of the susposed 'Big Bang' time of origin?

Question

The formation of 'walls' of superclusters of galaxies exist further in spacetime and beyond the limits of time placed upon the susposed time-point of origin of the 'Big Bang.' Given that it takes additional billions of years for stars to form, organize into clusters and form a galaxy, let alone clusters of galaxies then superclusters of millions or billions of galaxies, would their existence beyond the time frame of the susposed 'Big Bang' theory exclude this theory and beg that another theory be hypothesized in its place to explain this observational data? Is this not how science works - formulate a hypothesis, test it with experimentation and observation, adjust the theory or discard it if the observation or empirical data proves that the hypothesis is invalid?! Ithought pondering a little cosmology was in order. RTT

Answer 1

There was a conflict in some observations that the unverse was younger than some stars, however it was put down to an error in the instrument. The stars at the observable edge are as old as theory predicts the universe to be.

Answer 2

Our universe is 13.7 billion years old, so we can only see objects up to 13.7 billion light-years away. We have never seen anything farther than that. However, there are things farther than that, since the universe is infinite (as far as we know, of course, and until an experiment or observations comes along and disproves that idea). 13.7 billion light-years is only the edge of our OBSERVABLE universe. The light from a galaxy, say, 15 billion light-years away hasn't had enough time to reach us yet, it won't reach us for another 1.3 billion years.
Another way to think about it - Imagine 2 galaxies, one 13 billion light-years away in one direction, the other 13 billion light-years away from us in the exact opposite direction. So those two galaxies are 26 billion light-years away from each other. They can't see each other yet. Likewise, there is almost certainly a galaxy 26 billion light-years away from us, but we can't see it yet, either.

Answer 3

no superclusters are well within our universe, in my college astronomy class I mapped our known universe and could see the walls and clumps, one of these pictures resembles a stick man it's quite cute.
