(..) So, instead, I'm gonna talk about math. I am not a mathematician, but I do know this. There are infinite numbers between zero and one. There's point-one, point-one-two, and point-one-one-two, and... and an infinite collection of others. Of course, there is a bigger infinite set of numbers between zero and two... or between zero and a million. Some infinities are simply bigger than other infinities. A writer that we used to like taught us that. (..)2014 The Fault in Our Stars
