[QUOTE=Harnbrand;39230435]The idea of an infinite universe is a frightening thought because it means that nothing is finite or unique. Not humanity, not Earth, not our history, or solar system, or the particular arrangement or quantity of molecules that make up our bodies - There are literally an infinite number of copies of us somewhere out there, because possibility itself is infinite.[/QUOTE] No, that's not necessarily true. There could only be a finite amount of energy. Plus, there are plenty of infinite things which do no repeat themselves infinitely (e.g. irrational numbers) and infinite things which do not repeat themselves but do not contain every possible configuration of stuff in them.

The fact that something is possible doesn't mean it's inevitable, even in an infinite universe.[/QUOTE] I'm pretty sure it does. If an outcome is possible and you have an infinite number of chances for it to happen, it'd happen an infinite number of times. Don't irrational numbers do this eventually? Not that there's any way of telling easily. Of course I doubt the universe is infinite, or at least that it's contents are infinite.

That isn't true. It may be true on average, but not in general. Plus, INFINITE UNIVERSE DOES NOT IMPLY INFINITE ENERGY. If you don't have infinite matter-energy, you don't have infinitely many chances for some structure to arise. [editline]15th January 2013[/editline] Oh, I'm glad you brought up irrational numbers because they're a perfect counterexample. No, they don't do that, not in general. Some do, but they don't have to. For instance: 0.1010010001... Is infinitely long and never repeats and hence is irrational, but you'll never find the string 12345 in there. [editline]15th January 2013[/editline] Numbers which do have the property you're thinking of are called normal numbers.
