I cannot understand how there are “larger infinities than others” no matter how hard I try.

Question

I have watched many videos on YouTube about it from people like vsauce, veratasium and others and even my math tutor a few years ago but still don’t understand.

Infinity is just infinity it doesn’t end so how can there be larger than that.

It’s like saying there are 4s greater than 4 which I don’t know what that means. If they both equal and are four how is one four larger.

Answer 1

This one helps me understand better: there is an infinite amount of numbers between 1 and 2. There is an infinite amount of numbers between 1 and 3 as well but this infinity has to be twice the earlier infinity.
