    It’s fine, you just need to prove there is an infinite number of other inhabitants who would want to swap rooms.

    This is actually an issue caused by the hotel staff not allocating their rooms efficiently. When the first wave of infinite guests showed up, they should have assigned them to odd numbered rooms. Then theres still an infinite number of vacant even numbered rooms.

    Even if several more waves of infinite guests show up, you can assign them to rooms numbered 4n+2, 8n+4, 16n+8…

    That way, the hotel will always have rooms left over.

      Heresy! The staff should assign the initial wave of guests to EVEN numbered rooms with a dark chocolate on their pillow. Future assignments must be to 4n+1, 8n+3, 16n+5…

      Your heretical tyrany of the highest order will be purged. Only the pure must survive.

    0/5 stars. We stayed here for an infinite amount of time over the holiday. Every 10 minutes the staff moved us to a different room! We didn’t even get a chance to unpack our infinite luggage.

    I understand the idea behind this, but I always felt that it was a flawed concept.

    Maybe my understanding of complex math is limited…but I’m gonna keep pretending I’m smarter than everyone while I enjoy life in my delusional kingdom.

    Also this reminds me of the question “can god create a boulder so big that he can’t lift it?”

    The concept of infinity is to mathematicians as god is to Christians.

    EDIT: the above two statements were the jokey part of my answer, I thought it would be obvious but I guess not. ƪ(˘⌣˘)ʃ

      Infinity is effectively just bullshit.

      I’m found of pointing out to my students that there’s a very practical reason to care about “infinity” in math:

      While nothing every reaches “infinity”, things absolutely do reach a point where they violently fly to pieces and catch on fire.

      So I teach my students to substitute the phrase “explodes and catches on fire” where they see an equation that “approaches infinity”.

      I find it helps them pay attention to a subject that is otherwise bullshit. Infinity itself is bullshit, but it has a place in math: telling us when to quickly duck behind a good solid oak table.

      The comparison doesn’t work. Maths are abstract, you don’t “believe” in it. You build a consistent theory with minimum assumptions (axioms) and if something stops being consistent, it means some of your assumptions don’t work and you need to change them to build a better theory. Maths is an abstract tool, not a representation of reality.

      Infinity is just a concept you can define. There are tools to demonstrate something is true over an infinite space and obviously, you need those for a lot of basic maths. You’re not going to go anywhere in basic arithmetic or geometry if you can’t prove anything works over the infinite set of numbers or the infinite space.

        Furthermore, while mathematicians admit that math is entirely man-made construct, which is also the reason we have irrational constant, christian do no such thing.

          Imaginary numbers are a perfect example of that. It’s basically just “Okay, in the common number theory, you can’t get the square root of a negative number. What if you could?”. And what do you know, you can build a consistent theory where square root of -1 exists, and it has surprising properties.

          Intuitively, good luck trying to make sense of it. But it doesn’t matter, it works, and it’s useful to build other stuff. That in turn can be used as modelling tools in physics and all.

            I think it makes sense intuitively. It’s just most of us aren’t really trained since childhood to work with inaginary numbers. Sure, it’s not a 1:1 mapping to your fingers, but it’s not that unintuitive. Like when I do certain calculations I go into a second dimension of numbers where I can move around just as in the first dimension, because those calculations are outside of our current physical reality.
            I say current as if our reality will change somehow somewhen lol.

    This isn’t even unexpected. Once a person unwilling to change room is in first position, they stay there and considering that those people exist, this will happen eventually in the Infinite Hotel

      Considering this simple case, it will take just the time for the slowest guest to move to the next room as they can all take their luggage and move to the next room that should be vacant by the time they reach it.

      However, this is considering a magic comms system that lets all guest know to move a room instantly. In the case this is not available, the speed of light is the limiter and then it takes forever.

      Using the case with instantaneous communication, it is possible to take forever by trying to host a countable infinite amount of people as this is usually done by moving the original guests to the room that is double the current one and the new guests to each odd number left. In this situation, the original guests will take forever as for bigger numbers, the guests have to move more and more rooms each time.

      Sorry for the rant, I’ve seen too many Hilbert hotel videos

        Perhaps the hotel staff bring in a guest each day at a preset time. They just have to all move rooms at 5pm.

      Even if infinitely many guests want to stay put, as long as for every room, there is a later room willing to move, you’re OK.
