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)

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

VSauce is a science channel which I find both entertaining and educational. Fun and fast paced and often mind-bending. ▶ 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

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.

I really need a video on transfinite cardinals and ordinals beyond Aleph_0 and Epsilon_0. The VSauce video [1] on the topic only made me more curious with an elusive tree diagram displaying a few, and PBS Infinite Series [2] [3] just barely touched it. The mention of the Veblen hierarchies really piqued my interest, but much of what I've found on them has been a bit too dense for me. 1. ▶ this video 2. [link] 3. [link]
