Joshua Brown asked the Naked Scientists:

Hello

I have a question I can't get my head around.

If the galaxy and all that exists was created by the big bang, then what created the big bang? Surely there was nothing in existence before the big bang took place, and nothing in existence for the big bang to take place in the first place, simply because nothing existed.

So how then did it take place if there was nothing before it? What was existence before the big bang?

What I'm getting at, basically, is how did something come from nothing? (maybe I don't understand the concept correctly?)


What do you think?

======================
Before “ big bang “ was God.
And the God created the Universe and everything.
I now only two ways to explain this fact.
1)
The action, when the God compresses all Universe
into his palm,  we have named " a  singular point".
And action, when  the God opens his palm,
we have named the "Big Bang".

The Catholic Church agrees with this idea.
Look:

2)
At first God ( according to Quantum theory ) used the
Vacuum ( T= 0K ) to create “ virtual particles “ and
 they ( according SRT + QED and GRT ) created the
Universe and Everything in this Materialistic Universe.

Nobody agrees with this idea.

3)
Do you have another idea ?

hi friend,
of course, catholic church would agree with this cause, this theory involves God, however this is not physics anyways i thing , before big bang, i think their must be a larger or smaller body with infinite energy and exploded, giving rise to the big bang , i may be wrong

This is what I think;

 Before big bang, nothing = 0

After big bang, there are matter(+1) and anti matter(-1), which means;

 Although matter exists, on AVERAGE, the universe is still empty, because (+1) + (-1) = 0.

But of course matter and anti matter were not created in precisely with same quantities otherwise all would have disappeared.
Due to this in-balance a "little" bit of matter was left over that now forms our universe.

Actually, I don't think that there needed to be an imbalance in the amounts of matter and antimatter that were created to end up with the matter universe we have now.  All that was needed was for a tiny amount of both to not meet each other and mutually annihilate.

In terms of probability, which is more likely?

1.  Unequal amounts of matter and antimatter were created and 100% of antimatter was annihilated.

2.  Equal amounts of matter and antimatter were created but less than 100% annihilation occurred.

Afaik, there are some problems in ending up with unequal amounts of matter and antimatter without invoking additional factors, and the chances of 100% of anything occurring seem slim to me, so I'm totally undecided on this 'matter'   []

Yup!

Probably the creation process was too violent, matter & it's anti-matter counterpart got pushed away far from each other, making inhalation process much less probable. And it's a fact that in vacuum, matter are very far away from each other. (Please refer matter density / cm3 in the vacuum of intergalactic space: http://en.wikipedia.org/wiki/Vacuum)

I read A BriefER History in Time and understood it for a second. It was infinitively interresting. It explained everything.
