Vadar: actually, a good deal of your most famous scientists believed devoutly in a God, and as a group atheism seems to run no higher than in any other category. Due to the mechanics of faith, it's fairly easy to reconcile belief in a God with belief in the fact that if you drop something over a source of gravity, it will fall, and discard anything on either side that doesn't mesh. I mean, people talk about how evolution is a fraud, yes, but we also threw out the idea that the Sun orbits the Earth, because generally few people can find a way to believe in either one and still have their religious/scientific worldview function.
Actually what Nietzche meant by that supposedly comes out to more of a "God is irrelevant nowadays, and we don't need him". Of course, the context he wrote it in makes no sense, and if you read the book he said it in, he sounds more like he's just trying to shock the easily shocked than like he's actually being meaningful.
Oh, and given that the Universe is infinite (which it seems to be), than all that is indeed possible. However, it's not likely that if there is an immortal being (if whatever it is IS immortal), it will eventually die, same as it's unlikely that the Second Law of Thermodynamics (or any other physical constant) will change. Physics is NOT philosophy, by the way; science is an examination, with the implements we have, of how the components of the Universe work in order to expand that which we know; philosophy is the way of, by sheer reasoning, putting what we know together to form a coherent picture.
Styxx: Anyone who is so easily offended as to be shocked that others have different beliefs and ideas of their own has no business in a thread that involves thought, and should have better sense than to show up here. Same with trolls that just wanna insult people's ideologies. In fact, both are such repulsive sorts that they're not worth taking into consideration; I don't see why they can't be just recognized for the distasteful types that they are and ignored. If we can't have the occasional thread where people can discuss things that are truly significant in life, than this OT forum is absolutely worthless and should be deleted. There's very little redeeming value to the 500th word game or movie criticism on this forum- they're all the same, and I think somehting different is what is needed right now.
