We can never see the Big Bang or what happened around that time, because photons were not free to travel through the universe yet.
It is also important to realize that the word "universe" implies a totality of existence; it is everything that has, does, and ever will exist. So you can't say there is "another" universe - if it exists to us, then it is part of the universe.
The big bang was the BEGINNING of the universe so there was no temperature before it :P
Our concept of the "big bang" has no explanation about how or why, but our hypothesis is that there was NOTHING before the Big Bang created the universe.
The universe did not exist before the Big Bang. There was nothing there. It can be hard to grasp for young minds.
Before the Big Bang theory, many scientists believed that the universe was static, or infinitely unchanging.
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?
Events in the Universe are often dated from the Big Bang. But the fact is, NOBODY KNOWS what (if anything) happened before the Big Bang. The Big Bang MAY have been the start of time itself; but it is possible that the Universe existed (in some form) forever in the past.
In our Universe, ultimately everything started with the Big Bang. We don't know what came before that... or if there even was a "before".
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.
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 Big Bang (ultimately) made the stars, not the other way around. The universe wasn't even here for there to be stars in before the Big Bang.
No one really knows. Development would involve time and there was no time before the Big Bang. No one knows what was there before the Big Bang. If the question is "What did the Big Bang develop into?" the answer would be the universe.
Because God created it (or perhaps ordered it to be created). If you want a more scientific explanation: the Universe as we know it was the result of the Big Bang. What came before the Big Bang - or the exact cause of the Big Bang - are currently unknown.
