Absolutely nobody in cosmology takes seriously the notion that the Universe might be bounded. What would the boundary be? And if there is a boundary, what’s beyond it? Even if it’s finite, it’s surely still unbounded (possibly like a sphere, possibly like a torus or some other topological configuration).

If it’s infinite, then it has always been infinite. Never would it have gone from finite to infinite, just as your intuition suggests. [We had a thread on this this past fall](https://boards.straightdope.com/t/was-the-universe-infinitely-large-immediately-after-the-big-bang/1008983).
