The Infinite Hotel Paradox

Hilbert's Hotel paradox illustrates infinity's counterintuitive nature. A hotel with infinite rooms, all occupied, can still accommodate infinite new guests by moving everyone from room n to room 2n, freeing all odd-numbered rooms. This demonstrates that infinity plus infinity equals infinity, and some infinities are larger than others, challenging our intuition about mathematics.
