But we can never know it as we can only look back some 15 billion light years, which puts a finite limit on what we can say of the universe. Even so, the universe as we know it is the largest number of anything known, and it's still finite.

Also, when infinities pop up in physical theories, the theories are considered invalid,e.g., Feymann went to great lengths to remove them from electrodynamics. This is arguing from authority as someone has criticized me for. But it does indicate how physicists think.
