Ok, then nobody should be allowed to post any theories about The Big Bang. That is exactly what it is - personal theories! There is no 100% proof of evidence the Big Bang even happened! It sounds like all you want is YOUR safe standard model theories that everyone learns in school and REPEATS it over and over again until you think it's FACT. My theories are just as valid as any of this magical-universe-was-created-from-a-single-point-of-infinite-density so-called-theory.
Everything we have witnessed in the universe "so far" has obeyed the laws of physics. And yet when it comes to the (so called beginning of the) universe itself, the realm of supernatural and fantasy seem to invade thought. Anyone can believe what they want and repeat what they have heard.
Some try to find real solutions.
To answer your question - What we see as the observable "universe" may only be because our technology can only see that far. If there are blobs of matter that are 100s of billions or even trillions of light years away, we may not be able to see them........... yet.
No, it's about conclusions taken to the extreme. The clues we have, CBR, point to "some" kind of event that happened to spread the cosmic background radiation throuout the universe. Hubble's Law points to "some" event that led to objects speeding away from one another. For some reason, these points were taken to the extreme to invent the Big Bang theory and everything starting from a dot. pfft!
