I still can't understand how can people think the universe can be infinite. What do they mean by that? Is it already infinite? Then how come it's expanding? That's illogical. Is it potentially infinite in that it will expand forever? Not so, we already know it's going to end one day(though I really hope scientists are wrong about that last part).
I hate the infinite vs finite argument. Still doesn't require a magic man with a magic wand, and as far as our species and this planet and our sun, there is no dispute that in the scope of time and the universe we are FINITE and totally unimportant in that scale. 5 billion years from now there will be no record of what you or I, or famous or poor have done ever.
We still right now have a damned good measurement of scale of what is in the universe, and sure, with changing data our views will change, as they should. But that does not mean we know nothing at all, nor does it mean anything goes, nor does it mean fictional sky wizard claims born in antiquity and believed out of ignorance fill in those gaps. Only time, and more observation and testing will improve our understanding of the universe.
