Does the universe have an outer edge or?

The universe, being all there is, is infinitely big and has no edge, so there's no outside to even talk about. Oh, sure, there's an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. ... The current width of the observable universe is about 90 billion light-years.

Is the universe infinite?
