Copin your notion of Universe A & B is the question I had concerning why women were unable to carry their pregnancies to term if concieved on the island. (Almost like the Rh factor in pregnancies) If the mother and father are from Universe A (and therefore the parents' bodies suscribe to Universe A's laws of nature), but the baby was concieved in Universe B (and therefore the baby's body suscribes to the laws of Universe B), is that why there is a problem. Since the mothers don't die immediately upon fertilization of the egg, does that mean that Universe A & B have some laws in common (which sustains the pregnancy through the first trimester), but as the baby grows the differences in the laws of the Universi (that's my funny plural form of universe - ) begin to wreak havoc on the both the mother and the baby's bodies causing them BOTH to die? [Think of your umbrella again - at first both Universi start out at the center, but then as time moves on the mother and baby moved farther down their respective universe branches] And what about a hybrid? An island mother and and real world father (or vice versa) - or does it matter - the laws of nature of each universe are exerting too much force, they are just too great to hold any kind of blended universe life together?
What about jumping universi - either you have to travel back up your respective branch until you get to the center of the umbrella and then you can proceed down a different spoke of the umbrella, or, if the umbrella is closed and the spokes (or branches) are touching, can you more easily jump at those points? Is this what is happening to Desmond?)

It's been awhile since I've read Aristotle - but from what I can remember I think the unmovable mover does apply... (I will definately go re-read Aristotle's theory - ugh! more school work!!!)
