i iterate. what's the universe expanding into? if the universe is indeed expanding, it must be going somewhere. and for what we know, travel requires energy. the further it goes, the less it has to create another reaction. the less energy per reaction, the less distance traveled. etc. etc. until nothing. but this theory that is being presented would seem to create an alternate spark of sorts. this other source would make enough energy to keep the explosion and crunching constant. but that's according to the theories presented.

There's no outside surface of the universe. It isn't a ball. You can't fly to the surface of expansion, there being no such place. Thus, the surface provides no resistance to be overcome.
Everywhere in the universe probably looks something just like what we see here in our part. Stars and galaxies. Odd, but there you are.

What's the universe expanding into?I believe the universe is infinite in all directions. There is no leading edge of expansion. Space itself expands endlessly. Galaxies exist in all directions infinitely: Look at the Hubble Deep Field North and South.
In a sense there is no Big Bang: The early universe was infinitely denser and hotter. The speed of light also appears to slow down, as one approaches the Big Bang in a recent study of black holes.
This in turn raises the existential question as what "13 billion years ago" really means.
I'll stop my little digression at this point.

You are looking at things the wrong way. The universe isn't expanding into anything. It's the universe itself that is expanding.
You should study some elementary astronomy and cosmology to get an idea of what current theory is.
