inability to comprehend infinity in spatial and temporal terms, Our universe is not infinite, It is expanding which pretty much sums up that it has a current size. Time is also not infinite. Time began with the universe at the big bang. As far as our universe is concerned there was nothing before and no before-before. Still there are things that are provably infinite. The square root of two for example can be shown to have an infinite description even though it can be known to an arbitrary precision. You can for example graph a line that is the length of the square root of two even though no physical instrument down to a single atom or less could precisely mark the end of the line. Yes, it is mind blowing. So, a foam (which is entirely hypothetical) could have a definite size and yet contain an infinite number of "bubbles". And yes, multiple dimensions are also hard to visualize. I personally try to image the projection of the dimensions on our discernable space-time paradigm. That is to say, I can't see them all at once, but I can sometimes see (in my mind) the interaction of some on our version of space-time.
