eli5 Is there a reason that the decimals of pi go on forever (or at least appear to)? Or do it just be like that?

Question

Edit: Thanks for the answers everyone! From what I can gather, pi just do be like that, and other irrational numbers be like that too.

Answer 1

Fun fact, the typical number (one you pull out randomly from the real number line) is almost guaranteed to be a decimal that goes on forever without repeating. It’s not a special property of pi specifically, the vast vast vast vast majority of numbers are irrational.

It’s the numbers that DON’T do this that are the strange unusual ones.
