How Does Infinite Hotel Paradoxes Work?

The Infinite Hotel has infinite rooms, and it’s always full, but somehow, more guests can still fit!

Imagine you're in a hotel where every room is taken. A new guest shows up, but instead of turning them away, the person at the front desk just asks everyone to move to the next room: the person in Room 1 goes to Room 2, the one in Room 2 goes to Room 3, and so on. That way, Room 1 is now free, and the new guest can stay there!

Now imagine an infinite bus full of guests arrives, that’s like a never-ending line of people! Instead of asking everyone to move just one room over, the front desk says: “Everyone, please move to the room number that's double your current room!” So the person in Room 1 moves to Room 2, the one in Room 2 moves to Room 4, and so on. That frees up all the odd-numbered rooms, and now everyone from the infinite bus can have a room!

This is how the Infinite Hotel works, it's like having a hotel that never runs out of space, even when it seems full! The Infinite Hotel has infinite rooms, and it’s always full, but somehow, more guests can still fit!
