Nothing? Another universe? Our our universe is infinite? Honestly I don’t know and nobody knows yet. There are some theories of what it is outside, but it is something that is not being answered.

And what is before time?
I think to contemplate this type of question you have to extrapolate from 3 to 4 dimensions – there is a good short story/book, called ‘Flatland – A romance of many dimensions’ written in the 1880’s which tried to consider this sort of thing.
You can read the whole thing here:
http://www.geom.uiuc.edu/~banchoff/Flatland/It’s the story of a man who lives in two dimensions and has no concept of the third, and it tells of how he discovers it and how strange it is to him… a nice read and thought provoking.
I’d love to chat about this, but I fear i would never stop! If you really get into it, there are loads of books on it, and quite nice ones are by John Gribbin – if you tell your parents to get you one, I am sure they will, you know, for your ‘education’ (never mind that they are also quite fun!).

I think there are other universes. It’s a really interesting question though.
