Vsauce's Michael Stevens takes viewers past infinity using transfinite numbers, ordinals and cardinals, with input from mathematician Hugh Woodin. It is a fast-paced, mind-bending tour of different sizes of infinity.
HN recommends it as the most accessible introduction to what lies beyond infinity.

My personal favourite to illustrate infinity (as possible) and some math concepts around it is still the video "How To Count Past Infinity" from Vsauce: this video "This is math, not science." (~12:30)
The issue is that there are different infinities. The infinity the parent is talking about, the one that you generally run into in calculus class and the like, is straightforward. The research in the past century was about what happens _past_ infinity, e.g. ordinal numbers. I'm no mathematician either, so I'll stop there before I embarrass myself. The most accessible resource I found was this VSauce video [1]. [1] this video
There is one English definition of infinity, but when applied to ordinals ("degrees of freedoms"), you get different mathematical concepts of infinity. Vsauce's explanation is approachable: this video
Thanks for that, I hadnt' bumped into that channel before. After watching this one I watched the one on how to count past infinity....mind suitably blown :) this video
Completely offtopic, except for math and title, but highly recommended while waiting for the movie: "How To Count Past Infinity" this video
