    Want more? Try to solve the buried treasure riddle:

    The Infinite Hotel, a thought experiment created by German mathematician David Hilbert, is a hotel with an infinite number of rooms. Easy to comprehend, right? Wrong. What if it's completely booked but one person wants to check in? What about 40? Or an infinitely full bus of people? Jeff Dekofsky solves these heady lodging issues using Hilbert's paradox.

    So the hotel is not realy infinite, because it's literaly been full as you said, that must be a language abuse. I assume what you meant is "the hotel may be extended infinitly" which is slightly better '-'

    If the hotel had infinite number of rooms then why do all of this? Just move the new customer to the next room. Would save the manager from such brainstorming and the customers from disturbed sleep

    If your shift your so called paid guest, they will leave you hotel, and the loss will be infinite since then, and you might get bankrupt

    It would take an infinite amount of time to move all those guests. Reason: The manager cannot knock all the doors to move the guests (or he will have to do it infinity times). He also cannot send a signal, because the hotel is infinitely high, and light is travelling at a finite speed. Infinity/Finite Number = Infinity.

    What is the point of all this? Infinity is a theoretical concept, you'll never use it. Why do mathematicians always try to find meaning in what they do? Like there's a deeper level waiting to be uncovered. Just make sure buildings don't fall and cars don't crash and stop obsessing over pointless nonsense.

    Cannot strech infinite, if this is maximum what we have. This is like someone in stone age count distances to moon, when in real life he dont know nothing about it.
