What Is the Infinite Hotel Paradox?

Imagine a hotel with an endless number of rooms, and every room is full. A new guest shows up, but instead of turning them away, the hotelier just asks everyone to move to the next room. Room 1 goes to Room 2, Room 2 to Room 3, and so on. The first guest now has a new room! This is the infinite hotel paradox, where even when every room is full, there's always space for more people, because infinity keeps going forever.
