It's not important, since all of these calculations are based on what we know - as of yet. Give it another few decades and it might turn out to be even larger. Give it another few decades and what is now only considered a possibility, might turn into a theory. The multiverse.
It's huge, that's all that counts. And we're not even a dot making up it's entirety. Just the same way, as humanity is just a bad and shortlived joke compared to earth's history and preexisting life forms.
