Wouldn't the same logic that tells you that what goes in must go out, also tell that what begins must end? That there is no such thing as true infinity? Or at least not in the terms with which we use it. I mean, the length of a ring is infinite if you follow the ring, but the ring isn't very long, it's like we are locked into a certain perspective... but no doubt there's so much in the universe - and even in our surrounding - that we won't understand unless we change the angle from which we see it. Or see? How about: perceive with a different sense than those we already have or use? Anyway, the black hole being a connecting portal sounds surprisingly logical, and the universe is a fascinating; boundless topic. Pretty awesome speech!
