Imagine you have a never-ending bag of marbles, that's like infinity. Now imagine another bag with numbers on them, but still never ending, that’s a different kind of infinity, too. Just because both are endless doesn’t mean they’re the same! It turns out there are bigger infinities than smaller ones, and you can even count some kinds of infinity.
Examples
- An endless bag of jellybeans, you’ll never run out
