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

So you can count: 1, 2, 3… and so on to infinity

Or you can count the even numbers: 2, 4, 6.. to infinity.

Which one is larger(has more numbers)? Counting normally.
