Honestly?  I don't know the answer to that question.  But it seems to me 
that if the universe, and everything in it (including all its laws and 
dimensions) originated from this one marble-sized point, and that this 
point expanded to something larger than the universe in a trillionth of a 
second, then space (one of the dimensions of the universe) had to have 
originated from this one marble-sized point, and must have, by necessity, 
expanded.  If not, then the assumption would be that space has always been 
here, that it preceeded the big bang.  In addition, if it expanded into 
something that was larger than the universe itself, is there also an 
assumption that it has contracted since then to the size it is today?  And 
if so, how does that square with the idea that the universe has been 
expanding since the big bang?  I'm still confused.
