Doesn´t that mean that there is a black hole where the expanding of the universe started? Like a super-black hole and all the galaxies flying around it.
No because the Universe didn't start at some point in space. There was no space before the Universe. The Big Bang happened everywhere because the Big Bang is what created space.

Um... is that directed at the forum posters or the article that was referenced? Here's what the article says about an expanding universe and how it complies with their findings:
Both. I don't understand what they're getting at. Our Universe is expanding. Black holes aren't. What's the difference?

The article isn't talking about black holes. Like I posted earlier, it seems they have some beef with the theories surrounding black holes and have therefore tried to start some of their own theories from scratch based on data of what we currently perceive and call "black holes". Their findings have led them to the idea that our entire universe is a giant dark energy star, NOT a black hole (ie, not a singularity).

I could be called small minded, but I still find it hard to believe there was nothing before big bang. If there was nothing how could something come from it?
It's the exact opposite of the "God always was" thing.
It's all head bending stuff really.

When the matter started expanding it must have started from one point and expanded from there into space in all directions, like a ballon. But it seems that the lack of a mass point in the middle make sense since the universe wouldn´t be expanding if it was present, the mass would be keeping the matter from expanding.
These are just my personal speculations. :)

Space-time didn't exist before the big bang, so there was nothing "around" it that we could objectify. Basically, the question is pointless from a scientific point of view. There was no such thing as space, time or anything.
Although apparently there's some shit in string theory that is all about branes colliding but I know nothing about that and it is wacky shit for professors.

That still doesn´t answer the question what caused the big bang and where the matter came from in the first place.

I didn't say nothing existed, I said there was no space. Specifically no space-time. Space-time is a property of the Universe. Without the Universe there's no space-time. What was there when there wasn't a Universe? Who knows.

The galactic redshift we see isn't due to galaxies moving away from us through space; it's the result of space itself expanding. The matter isn't moving in relation to its local space-time.
You're thinking of the Big Bang incorrectly. The Big Bang isn't an explosion of matter in existing space. It's the creation of the Universe. It's the creation of space, time, space-time, energy, matter, forces, everything. It happened everywhere because there was no anywhere before the Big Bang. Because it happened everywhere there's no center. You're living in the Big Bang. The entire Universe is the Big Bang.

I know that, there was nothing before the Big Bang, no time or matter nor space. But I was rather thinking long after the Big Bang occured that there was still matter where the Big Bang started. I read that the first stage of the theory is that first a soup of matter is formed and in a few nanoseconds the matter had expanded many lightyears I think. I can´t remember where I read that though, most likely outdated version of the theory.

You're not listening. There is no "where the Big Bang started". It started everywhere.
The theory you're talking about is called Inflation and the inflationary period happened before there was any matter. The Universe would have still been too hot at the time to contain anything but energy. I don't know how in vogue the theory is these days.
