Finite universe, logically it seems to me that if the universe is infinitely large it also has to be infinitely small. Right now it seems quarks or component strings roughly their size are the smallest things possible. So we are just a few orders of magnitude removed, if the universe were infinitely large it would be an incredible stroke of luck that we were so close to the smallest. Now if you change the frame of reference, if you choose something infinitely larger than us we become infinitely small to them. I think where we are heading is that infinity is a meaningless quirk of math, not relevant to the discussion of the cosmos like the divine spark of life or phlogiston proved to be imaginary barriers that disappeared under scrutiny
