What is infinity and is it a number?
You've heard the word a thousand times. Maybe a thousand-and-one. Infinity — the thing that never, ever stops. But here's a question nobody asks at dinner: is infinity actually a number, like 7 or 42? Plot twist: not really. And the reason why is far stranger and more delightful than you'd think.
