Actually, to make this the most correct statement you would have to change it to say "the universe as we currently define it". Everyone thinks of the universe as a giant sphere expanding into nothingness, however, it would also be plausible to think that in nothingness there is also another sphere that is expanding which would also be a "universe" such as jewpins multiverse. If we were to gain knowledge that would lead us to believe this, then our concept of the universe would shift to being what contains the two rapidly expanding spheres. In this such case, it could be infact infinite if knowledge continues to grow without a stopping point.

Also, infinity in of itself is a concept and nothing more. You cannot prove or disprove infinity because you are bound to finite lives in the realm of time and existence. If you could infact break these bonds and live outside of time which allows you to see it as a whole, then you could see a specific even never ending. Aside from this, it is just a concept used to describe an event (such in math) where and increase or decrease of data will not end according to its parameters.
