I would apply occams razor is this scenario though, sure there is probably life in other parts of the universe, but we could research ourselves or ANY THING PRESENT in the universe and find laws relative to it anywhere else we go..
Sure like love, like light, earth is a spark in an ocean of darkness, but of course there are others, we don't need to prove it, it proves itself. For it wouldn't shine or work the way it does without the space around it..
I think applying some of einsteins little laws with logic and some modern discoveries can definately give us a theory of the universe, for what it is within us, is within all matter, what is in anti-matter is just the other side, effectively we could work out our universe, from the multitudes of information we can find in a single thing.
