Current theory is that the universe actually occupies 11 dimensions, which with the combination of string theory help explain how gravity has such a little effect on our universe, quantumly and plantry. That gravity could itself exist outside of our viewable universe and bleed in. They are trying to show this at CERN by the creation of black holes that are no bigger than an atom, when particles are collieded.

It is then thought that there are many many universes all stacked next to one another and they pop into and out of existence like bubbles being blown, but WITHOUT someone blowing.

That time is simply a vector and that in the grand scheme of things it is just a human ideal not a universal constant microcosmically. However marocosmically it is the only constant, has always been and always will.

I havn't read everything that people have posted and if i have reiterated what someone has already said then i apologise. I also dont want to get drawn into a wider god debate, if you choose to belive what you believe, thats cool just dont cite it at me. It doesnt work.
