We cannot see the entire universe. Only what is within the visible horizon. We see galaxies far away, moving away from us, a red shift in the visible light, indicating they are moving farther away. So if we see a Galaxy 4.5 billion light years away, we really see it was 4.5 billion years ago because that’s where it was when it emitted the light we’re seeing, meaning we were closer to it 4.5 billion light years ago, but since that time the universe expanded, making it much farther away than what we currently see. Meaning, the light it is currently giving off, in our present, potentially could never reach us, depending on the rate of expansion, as we’re moving too far away as the universe expands. This is scientifically proven, that we only can see as far as light could travel to us. So anything outside this range, we will never be able to see. What if our part of the universe is expanding, but there are other parts of the universe so far away that they didn’t start from the same big bang that we think to be the whole universe, and that the big bang theory only applies to our portion (our visible universe) of the universe.

We intuit the Big Bang Theory based on the expansion of the visible universe, and conclude, based on the red shift of light, that it all originated in one point in space. But, the necessary limitation to this theory, is we make the assumption that the entire universe, even that outside of our visual field, also originated from this point. It is entirely possible, that our corner of the universe, that is visible and able to be mathematically deduced to the theory of the Big Bang, is not the entire universe. It is possible, that there are areas so far outside our range, that if we could gather data on, could point to a different origination, or possibly to eternity.

We can’t record data on parts of the universe that we can’t possibly come in contact with. What if these unrecorded parts of the universe point to a different beginning than the Big Bang, which only accounts to our visible universe based on the data we have of. We would never be able to approve or disprove this theory, because there never could possibly be evidence of galaxies that are so far away, our expanding portion of the universe makes them expand away from us faster than the speed of light, it only could be proven if a Galaxy previously not within our visible portion, that couldn’t previous be seen, was now seen moving into our visible universe from some unknown outside space. Could it be possible that there are parts of the universe that were, are, and will be, never visible to us? Even at our intuited Big Bang, they were so far away that even light couldn’t travel far enough to reach us, and after the Big Bang, they just got farther away?
