The entire OBSERVABLE Universe must have been smaller than the size of a proton. Since the ENTIRE Universe is much larger, and perhaps infinite, we really don't know how large that was.
The Big Bang is the theory that was developed to describe the origins of the universe.
It is similar to the Big Bang theory. The ekpyrotic theory is, a theory that their is a parallel universe (More than one) In our universe.
There are two questions commonly asked:1. Is it real, or did God create the universe ex nihilo?2. Did the Big Bang create more than one universe?3. How can the big bang account for dark matter and dark energy?
We know how big it is now, we know how old it is, and we know the rate of expansion. Its like rewinding a movie that you started in the middle. We just rewind the known universe as it is now. We dont know how big it was before the big bang but we know how big it was at the initial kaboom.
The Big Bang theory
It is "The Big Bang Theory."
Before the Big Bang theory, many scientists believed that the universe was static, or infinitely unchanging.

Well I do now one theory about the universe. It's the big bang theory. The big bang theory is a theory about how the universe was created.Scientist think that a big explosion created the universe.Scientist found lots of evidence that the big bang theory was true.
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?
The concept of a "very small and very hot universe bubble" before the Big Bang is speculative and not universally accepted in current cosmological theories. The prevailing theory, the Big Bang theory, posits that the universe began as a singularity and expanded rapidly from that point onwards. The exact origins of the universe remain a subject of ongoing scientific investigation.
If there is no black hole, then no Universe, we will not be exist. That's why there is a Big Bang. The Universe started off with a Big Bang from a black hole. Though if you want to know what happens before our Universe, then you need to study 'String Theory' and the 'M theory'.
The Big Bang theory states that the Universe started with all currently existing matter, concentrated in an extremely small, space - in an extremely hot and dense state. It is not clear what happened before that, or whether there even was a "before".
That is, more or less, the description of the Big Bang.
