The big bang time was at the exact time when things made a large but silent explosion. Hope that helps.
the big bang theory
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.
According to our current understanding of physics, there was nothing "before" the big bang; not even time or space, so the notion of "before" is probably meaningless. We cannot imagine the conditions at the time of the big bang.
Intellectual life (or life at all) did not exist during the time of the Big Bang.
The Big Bang! Space-time did not exist before the Big Bang so there can be no earlier events.
In the current model of the universe the big bang was the 1st thing to happen in the universe since time itself was created in the big bang.
There was no such thing as 'space' before the Big Bang. In fact, there was no such thing as 'before' before the Big Bang. Space and time both began with that event.
Without the Big Bang there would be NOTHING. The entire Universe - including space, and apparently even time! - is the result of the Big Bang.
According to the scientists big bang is the main reason of the creation of this universe. after the big bang only the matter space and time came into being
There was no beginning as it has always been.Answer:Philosophers and physicists disagree about the start of time. Stephen Hawking (a physicist) suggests that that even if time did not begin with the Big Bang and there were another time frame before the Big Bang, that information is not accessible to us. It does not exist and cannot be proven. Effectively time starts with the Big Bang some 15 billion years ago.As to where this happened, the Big Bang by its nature is the centre of the Universe.
This is not known at this time.
