There are different theories some coming from the fields of science and others from religion.
The real answer is that no one really knows.
Read article below for some of my ideas on the early universe
Science is based on the empirical study of cause and effect. The hypothesis formed by anyone has to be testable to establish a theory. Now, if the Big Bang is the effect, its cause can be studied only before it happened. But according to the cosmological theory of the Big Bang, there was nothing before the series of events occurred. No space, not time, not even matter…NOTHING!! Then out of ‘nowhere’ appeared a high temperature, high density ball of matter smaller than an atom and ten trillion trillion times hotter than the core of the Sun. This is called the ‘initial singularity.’ The energy contained in this tiny yet infinitely dense ball of fire was 4*10^69 Joules. That is 4 followed by 69 zeroes. As it started to expand, in the first second after the Big Bang, the blueprint of the whole universe was written.
That being said, coming to your question, as the cosmological theory of the Big Bang itself suggests that the fabric of space time did not exist before the big bang, there is no way of observing the cause of the event. Because TIME WASN’T THERE! Thus through science, this fact will always be unknowable.

What was the "medium" within which the "Big Bang" happened? There are other interesting considerations.

I'm interested in your thoughts. Not how. I'm not interested in the idea that a god did it or not. I am interested in your thoughts on why there is something instead of nothing.

As I understand it, everything did not exist at all a nano-second before the "Big Bang" and everything, absolutely all the energy in the Universe was in existence a nano-second after the "Big...

Does the Big Bang exclude God or does it prove His existence even more?The universe began with the Big Bang. This is essentially conclusive and may stand as the most profound discovery of all time.

Do you believe in the theory? What is your view?

Did a big bang really happen?
