pin size point
Ok, this may seem slightly "out there", but that's why we're here right? Why would the universe start from a so called "pin sized point"?? If it was the only thing out there wouldn't it be the biggest and smallest thing there is? Kinda infinite?? oh and to add to that, why would it have to explode/expand for anything to occur?

more dimensions
I'm curious as to how more dimensions make a difference. Could you elaborate on how more dimensions would effect it?? I'd really appreciate it.
The problem is that everything we see around us and study is in the 4-dimensional world. If some of the current theories are correct, and there could be as many as 11 dimensions (not that I'm qualified at all to say if/how correct they are!), there's nothing stopping and contraction in our dimension, since it could be supported in others.
I think the point is that we don't know! Hawkins recently suggested that as you get closer to a massive crunch (i.e. going back in time towards the bang) the time dimension becomes more and more spatial, so maybe there isn't a t=0...
There's also a load of other theories involving energy membranes at higher dimension colliding and causing it all.
You could also argue that our entire universe is nothing but a quantum fluctuation - my personal favourite as it means that there's no point to it all!![Smile :)](./images/smilies/icon_smile.gif)

Actually, there is at least one theory out there that assumes 27 dimensionsEmpeda2 wrote:The problem is that everything we see around us and study is in the 4-dimensional world.

Slan go foill!
That's very true - though I was thinking more of the theories that have many followers - but indeed, whatever the number of dimensions, we are stuck in our percepted 4....gordhaddow wrote: Actually, there is at least one theory out there that assumes 27 dimensions

I think in string/M-theory, the points is that these other dimensions are too 'small' for us to see - they use some kind of analogy involving an ant walking on a wire but I can't remember it....
....*ahem* Anyone?.....

The funny thing is that we use maths and other ideas to make things fit to a model we want and believe in.
At this particular point in time many cosmoligist sare re thinking alot of the past evidence and observations with a new eye of thoughts.
When the dust settles within the next few years many changes and new theories will be born.
Have a nice Day
