    But there are infinities which are larger and smaller than other infinities.

    -infinity is smaller than +infinity for the most simple example.

      To add to what Kabi said, IIRC only when you’re speaking in set or groups do the infinities become “larger” (simplified and not 100% accurate). I.E. infinity of regular numbers vs infinity containing all the variations of positive integers added. The latter would be “larger” cause it contains multiple infinities or “sets” of infinities and is infinite within itself. This video helps explain probably better
