The Doctor took back the mug and stood it on the tables beside one of the laptops. ‘Ever heard of o-regions?’ Nesbitt shook his head. ‘You?’ he asked Lansing and Phillipps. Neither of them had. ‘Pity.’ The Doctor dipped his finger tentatively into the mug, snatching it away almost immediately. ‘An o-region is a part of space that is so far out, so isolated from everywhere else that its light hasn’t yet reached the rest of the universe. They’re big,’ he went on. ‘And being isolated, they are in effect mini-universes in their own right. If you can conceive of a mini-universe.’ ...‘There is an infinite number of o-regions, each developing Iike a mini-universe in its own way. And since you could, in theory – though I wouldn’t recommend that you try – work out every possible collision point and potential change in our own universe to date, that means that there’s only a finite number of possible histories. Huge, but finite.’ ‘And what does that mean?’ Nesbitt said. ‘It means that every possible version of history that you can imagine will occur.’ The Doctor grinned. ‘In fact, given the rather strange way that maths with infinity works, it means that every possible version of history will actually occur an infinite number of times.’

No that is just the observable Universe, the Universe that we can detect / see. The actual Universe itself is much bigger than that, so we're not the centre of the Universe but ofcourse we are at the centre of our observable Universe. Ofcourse if you'd be living on a planet in the let's say the Andromeda galaxy, you would also be in the centre of the observable Universe seen rom that planet.
Because you will have the observable Universe seen from Andromeda.

Anyone else feel some what skeptical when the mainstream answer is that: "it is flat". And how they use mysterious things, almost like sea monsters as proof that it is flat?

I must admit to a limited amount of true understanding on this topic, and I have always had
problems understanding "circular" arguments.
However, when I look up at the night sky I see a field of stars which are quite obviously in
some form of three deminsions. They extent away from me in all directions. I have been told
that many people once believed the earth was flat and the stars moved around it.
If the universe is flat ( has only width and length ), why does it appear to have such depth in all
Also, I have a problem thinking of an "explosion", which the big bang must have been, only
expanding in two directions within an unrestricted environment which must exist outside
the volumn of the universe itself.
Astronomers have glimpsed the most distant galaxy ever detected — a lone object 13.2 billion light years from Earth. The discovery implies that the fledgling Universe was emptier than was previously imagined.
The galaxy was spotted in the Hubble Ultra Deep Field, an infrared image of the night sky that contains the faintest and farthest objects so far pictured. The finding "pushes the data to the very limits", says Rychard Bouwens, an astronomer now at Leiden University in the Netherlands and a co-author of the study, which is published today in Nature1.
