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.
