Fair enough, with the right distinction between universe and observable universe they are certainly compatible.
Any discussion of the characteristics of the universe outside the observable universe runs into some interesting epistemic problems around what constitutes evidence. Maybe it's turtles all the way down, or teapots. Good luck trying to estimate the prior probability of an infinite number of possibilities with an ape brain that evolved to hunt and gather on the Savannah.
I find a lot of pop science at the fringes of our knowledge (QM and astrophysics) relies a lot on infinities to justify cool stoner ideas that are unfalsifiable and chosen entirely based on human biases of what would be "awesome". I do have a very strong bias against these because of this obvious element of wishful thinking. The infinite-alternate-realities-of-the-gaps argument is just the god-of-the-gaps argument for the "I fucking love science" crowd.
That's still my understanding after some cursory googling to make sure I didn't totally forget something from college.
