I love thinking about infinity. Thinking about more than infinity is even more fun. If you agree, then check out this short video from Veritasium. I watched it several times and still have a hard time wrapping my brain around it. However, I also watched a longer explanation from Vsauce, so I understand how it is possible to count past infinity. But wow, what a mind-blowing concept.
Luckily, I like having my mind blown by science. If you do, too, I hope you enjoy these videos.
