  • If there's a hotel with infinite rooms, could it ever be completely full? Could you run out of space to put everyone? The surprising answer is yes -- this is important to know if you're the manager of the Hilbert Hotel.

      maybe weird idea of me but why not put the one more guy on the end of infinity instead of the beginning. because if you can move everyone up one you should be able to put one at the end . maybe because infinity is not reality ?

      Basically imagine how you can fit an infinite number of numbers between 1 and 2 such as 1.1, 1.2, 1.9, 1.99999, etc. 1 - 2 is the hotel and countable infinity.
      1.9999999 would be the uncountable infinity and people on bus

      A solution would be to only move the people who arrived in the last infinite group. That way everyone will move at most once. For the people who arrive in finite groups, you could just set aside the odd numbered rooms at the start and the do all the other stuff only on the even numbered ones.

    I booked 1 night in the Hilbert Hotel and it was horrible! It was 10pm at night when I arrived and the receptionist asked me to move to room 13739 and the elevator is still broken as many comments mentioned here, plus a 30003 seater bus pulled up and the receptionist asked me to shift to room 43742 and I had no time to collect my stuff I brought to the hotel with me. The other guy who took my original room who was on the bus also took my stuff, INCLUDING my laptop. Even when I was sleeping, I was asked to SHIFT to double of my room number and was like "F************ this" and completely checked out at 1 in the morning instead of 12 noon which I promised to the receptionist. Bad hotel, don't go here. Would give 0 stars if there was even an option.

For that they needed infinite helpers, infinite kg of detergents, cleaners, etc. To produce that in a single day, the factories need to produce that in infinite quantity. Now the delivery trucks came to the nearby cross-circle. They will create a infinite traffic jam. Infinite parking will be needed. How could one deliver the product who is standing last second from intinity. It had to travel infinite km. Husshhhh!! So mess

    Great video, but I noticed a potential inaccuracy in the explanation regarding infinite rooms.
    Here's the issue: The guest labeled "no room" wouldnt occur in an infinite spreadsheet. Even if a new infinite guest bus comes over the next minute, it would still have a room because we can infinitely shift existing guests one room over, creating a chain reaction with infinite vacancies.
    The true challenge lies in managing (assigning/tracking) an infinite number of guests, not a lack of space. Our finite human methods struggle with handling infinity.
    Therefore, the answer to "Could you run out of space?" is definitively no. Infinite rooms can accommodate everyone.

    Regarding the infinite number of buses with infinitely many people, I like the solution of using prime numbers.
    First, send guest in room 1 to the 1st prime number, then guest in room 2 to the 2nd prime number, etc. Now all the rooms with prime numbers are occupied, and the others are free.
    Put the people of bus 1 into the rooms 2^2, 2^3, 2^4, etc., as these aren't prime numbers they're all free.
    Put the people out bus 2 into the rooms 3^2, 3^3, 3^4, etc.
    After you do it for all prime numbers, all the powers of prime numbers will be occupied.
    Bonus, all the rooms with multiple prime factors (e.g. room 15 = 3*5) are now vacant, so you even squeezed some free space out of that trick.

Just consider the rooms that have powers of 10 as their number. These rooms themselves form an infinite sequence, yet they make up a 0% proportion of the hotel in total. I'll now refer to these as the 'switch rooms'. I will also refer to guests by their previous room number.
      If guest n wants to leave, just shift guest 1 to room n, and fill in from the shift rooms. (If room n is a shift room, simply fill in from the higher shift rooms instead.)
      If a guest wants a room, make space in room 1 using the shift rooms.
      If countably infinitely many guests want a room, draw a bijection to the natural numbers, vacate all odd shift rooms (guest in shift room n goes to shift room 2n for all natural n), and fill the odd shift rooms with the new guests.
      If countably infinitely many guests want to leave, draw a bijection to the natural numbers, fill the gaps using the guests in the odd shift rooms, and fill the shift rooms back in (guest in shift room 2n goes to shift room n for all natural n).
      If an uncountable number of guests want a room, turn them all away.
      Using this method, any long-time resident of the hotel will eventually be assigned a room which isn't a shift room, and 100% of guests would be satisfied.

    Just make a new infinite hallway, send one infinite group down one infinite hall, and a second group down a second infinite hall, its like making two hotels

      "its like making two hotels"
      Even an infinite number of hotels cannot fit the ABBAs.
