[renormalised (Carl)]

That's an old idea, even older than Sagan's espousing of it. It's very much like the old Chinese "turtle on a turtle on a turtle" cosmology. Much like those Russian dolls, one within another within another. It's actually rather funny, you know. You then have to wonder just where our "elementary particle" of an Universe is located in the larger scheme of things. I mean, are we part of some person's finger or the tip of their tongue?? Are we a part of some thrown away piece of paper or scrap food?? And are they, in turn, a part of something even larger still....like a cooked lobster meal on a gigantic dinner plate or a pile of pond scum??

I mean, we might just be what's being flushed down a gigantic toilet....that would explain a lot of things
