Actually the discussion is important because ,we are not sure enough that where from the universe came indeed. At that time in Big Bang singularty moment, universe had a temperature of 10000billion degree celcius and a density of 1000,000 billions tonns of water density & had a controversial physics and mathematics that can explain every thing that evry thing happened from that time 0.0001 second after the time zero up to present day. According to us the Bing bang model is acceptable after 10-32seconds of the Big bang singularity. What hapened before 10~32second? The next thing is that whether time was started from the Big bang moment or Time was flowing and Big bang like events happened only once? or many such Big bang like events happened in universe?

We think there was only one Big Bang (in our observable universe, at least) because the evidence we see is that everything in the universe (on large distance scales) is moving away from everything else.
If there were multiple Big Bangs, then presumably you would see some faraway galaxies moving towards each other, or at least a more complicated relationship between the distance of objects we see and the speeds at which they appear to be moving away from us.
i personally don't believe that time started from the Big bang moment.its just that it is a good reference point.

I'm not into the technicalities of the big bang ( as in seconds etc ) but the " big bang " did indeed happen --- otherwise we would not be communicating --- we wouldn't exist --- but bear in mind an old saying that what goes up must come down --- and because gravity was accentuated by the ( if you will ! ) big bang --- then i guess it will be swallowed up by the same phenomenon which will in due course --- take us back to the void from whence we came ( it won't happen in our lifetime --- or indeed other generations --- because the world will self destruct ) long before this event will come to pass . good luck and enjoy life to it's fullest

Get, study, and revel in "The stylish Universe" by ability of Brian Greene. it is straightforward analyzing and correctly written. It covers lots of what your question asks. yet indexed right here are some excerpts: First, there could certainly be different large bangs in our universe. the solid information, probable, is that those others have not intersected our time-commemorated universe. this is a few thing like 2 rocks thrown right into a pool (the universe) and the ripples from each and every improve outward (the time-commemorated universes). we are no longer able to work out previous approximately 14 billion easy years from Earth because of the fact it is for all time (14 billion years) easy has been vacationing because of the fact the BB. 2d, there is dissimilar universes, some thing like slices of bread in a loaf of a metauniverse. The collision of one of those dissimilar universes (which lie in larger dimensions) with ours might desire to account for the large mass-potential released because of the fact the large bang (BB) in our universe. finally, some parts of string/M concept do posit time formerly the BB. This follows from the seen 2 universes colliding, meaning they have been shifting by larger dimensional area; meaning masking area by the years, hence time existed formerly the BB. in case you like this form of concern, you will love the stylish Universe.

you cannot say that it was the beginning of the universe, there could have been many more "big bangs" but we won't be able to find it out until we are enriched with info from each part of the universe.
we can't predict "big bang" because we don't know what was the cause for the it!

Why won't it happen now?
You've answered it in your question with the use of the word "singularity".
The Universe is clearly not currently a singularity.

No one understands why it happened, what caused it or if it will happen again. The question has no answer today

There can only be one bigbang at any given time.
