Is the Universe Infinite?

The rules of the universe seem to be the same everywhere. There don't seem to be any special locations. And so i thought at everything was moving away from a central point, but is that not true? Soo, no matter where you are in the universe, it will look like everything is moving away from you. I am probably the center of the universe, but maybe i'm not. O, you're the center of your kid's universe, i'm sure. But this question about why the night sky is dark is actually a really old question, and predates any modern understanding of the size and shape of the universe.
