Physics, Astronomy & Cosmology / What existed before the Big Bang?

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?
Right. First of all, yes you are right, despite some scientists interpretations of the infinite concept of birth from nothing situation, so this is hard to talk about, because these differences exist for many other differences. In relativity, if space just began at big bang, then so must have time as well, because in the end, the Minkowskian Equations describing space and time, is linked them as four-matrix spacetime dimension. The unity of the birth of time, would be the same as the birth of space, and vice versa.
So there may be no escaping this, as current theory suggests, with a great deal of evidence, some would argue proof. There is however, another option. There is a theory called the Ekpyrotic Thoery, which is revolutional, but bold theory (which some have argued is at best, speculational), suggests that the universe was in a frozen state before big bang. It also says this could have continued for eons. Maybe hundreds of eons.
The big bang was result, (under this theory), of a collision with this universe with another. We call these brane collisions, and under an Everett Interpretation of quantum mechanics, this would suggest that layers all superpositioned together, have a flux, in which only two universes bend into each others existences. The strong interelation, may as well be related to the gravity and collapses in the wave function. This collision is supposed to have ''awoke'' the dorment energy in this universe, so the Ekpyrotic Theory can be seen not only a mechanism for the energy and spacetime in this universe, but also giving a timen (literally), before big bang.
