Interesting thought, JoBelle. Several years ago, I read a novel (can't remember the title though) with a similar speculation, constructed on the fractal similarity of structures in stellar systems and atoms:
What if all the solar systems are just atoms, the galaxies are molecules, and our whole universe is only one cell in a huge, n-dimensional organism? That way, one could explain why all scientific laws work in our whole universe. They would just work according to an n-dimensional DNA program. We would never get even the slightest idea of what our cell is doing in this organism; the scale is just too big. Some would explain this fact with the word 'God'.
You could even develop this idea further, by speculating that each atom in our world is just an incredible tiny solar system, with even tinier beings on the 'planets' (electrons), and they in turn are built of micro-atoms which could be solar systems themselves, etc. etc. etc. And again, we'll never get an idea what these small worlds would look like or how they function; the scale is just too small. Would we be the 'God' of such a smaller universe?
This idea would also be corresponding with one strange observation in our own universe: Everything seems to be constructed in fractal structures, i.e. every feature of nature is repeating in constantly smaller scales (best example: coastlines, or trees). But of course I realize that this is not even a scientific theory, merely a philosophic brain-wrecker (albeit a very interesting one!)…
