If I've gotten the right impression, much of our currently visible universe will eventually be expanded away from us, never to be seen again. Do we already know how much and what parts of our present neighborhood we'll be left huddling with?

If the expanse of the universe is infinite, does it necessarily follow that the number of stars and planets is also infinite?

Is there an existing philosophical or cosmological model that regards the universe as a living thing with the observed patterns and "laws" of the universe being a reflection of an inherent model analogous to the genetic models of living things as we know them? My own uneducated philosophical meanderings have led me to this idea and I am wondering about developed theories or philosophies that follow similar lines. [more inside]

"A human is halfway in size between an atom and the known universe"... This is a paraphrased quote I have come across several times. I like it. Who said it first? How true is it in the most literal sense? And, finally, what errors arrive in postulating a universe, or an atom, which can be measured AT ALL from our singular, relativistic, perspective?

Is it cosmic coincidence that the moon spins once on its axis in exactly the same time it takes to orbit the earth (hence the dark side we never see from earth) or is there some reason why this should be more likely?

Can anyone recommend any good recent articles or papers on whether the universe is infinite or finite? I've heard that scientists suspect that the universe is flat, which lends credence to the infinite-universe hypothesis. I've decided I don't know enough about this. Nothing too technical, please, though I'd prefer something more complex than an article from a newspaper science section.
