How An Infinite Hotel Ran Out Of Room

- 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.

Imagine disturbing an infinite amount of clients just to fit one more person in the hotel
I'm just saying that supporting an infinite number of people has got to put a toll on the economy
It's ok. When you are settling in an infinite hotel you have to deal with consequences.
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 ?
@@jeroen5736 I wish you luck in finding who's at the end of infinity.

It's ok your making an infinite amount of profit anyway, so even in an infinite amount demand a refund... hmmmm
imagine checking into a hotel at 5 am and realizing you have to walk to room 900 quadrillion
They wouldn't have to the 1st customer would be in room 1 the next customer would move into room 1 and the 1st into room 2 and so on so they don't have to walk that many doors

Nah what about the p2m pay to move hotel?
Hey, sorry for this but you need to move to room 91 google, and to use an elevator, you need to pay $200qui.
You need to move to room 1+ +1 ( 1+ +1 is uncountably infinite because we dont know what to add for 1+ so we add the awnser to +1 but there is none so we do 1+1 to do the equation 1+ +2 but it will become 1+ +1+ +1 for mathematical logic then the process repeats becomings 1+(1+(1+(1+(1+(1+(1+(1+(1+(1+… forever )
I like how he explained it in such an understandable way to shield my brain from realizing I actually understood nothing.

Dude, the people staying in that hotel must be pissed having to move so much.
I'd imagine going for a vacation, and the only thing I'd be doing is changing rooms. If someone asks me what did I do during my vacation I could say I've been changing rooms the whole time.
Price you have to pay for having an infinite amount of vacation members
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 would just walk until I get hundreds of rooms away from the first avaliable one. Lots of walking, but worth it
I mean, they're infinitely moving.

Reminds me of a Monty Python sketch about interviewing a German person with a very long name, I almost died laughing it's so well delivered.
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.
Remember that one time where someone pulled the fire alarm and the whole building had to evacuate the same emergency exit? Pranksters man. (Doordash also wont deliver here) 1 star
I stayed at the Hilbert Hotel back when it was known as the Premier Inn, Heathrow. There were so many people at breakfast that it just had to be a thought experiment.
There's 7 billion people and it can fit 7 billion rooms. There are leftovers here. 0.000000000000000000000000000001 stars

I can't wrap my head around the concept of infinity.
It’s a concept that is really difficult to grapple with, especially when thinking of it in terms of an infinite universe which means that there would be an infinite number of possibilities. I asked ChatGPT whether in an infinite universe there is a planet full of dogs and this was the response:
In an infinite universe, the possibility of a planet full of dogs does indeed exist, according to the concept of infinite possibilities. Here's why:
1. **Infinite Space:** In an infinite universe, there are an infinite number of planets and celestial bodies. With such vastness, virtually any conceivable configuration of planets and environments is possible, including planets that are inhabited entirely by dogs.
2. **Probability and Randomness:** In a universe with infinite possibilities, random fluctuations and chaotic processes can give rise to a wide range of outcomes. While the likelihood of a planet being inhabited entirely by dogs may be extremely low, it is not impossible within the framework of infinite possibilities.
3. **Variety of Environments:** Planets can have a wide range of environments, from rocky and barren to lush and habitable. In an infinite universe, there are bound to be planets with environments that are conducive to the existence and proliferation of certain species, including dogs.
It's important to note that the concept of a planet full of dogs is purely hypothetical and speculative. While it may seem fantastical, the idea illustrates the vastness and diversity of potential configurations within an infinite universe. In reality, our understanding of the universe is still limited, and we have yet to explore even a fraction of its vastness.

Basically anything that can happen in an infinite universe will happen.

There's no such thing as infinity, it is by its own definition, not quantifiable.

The logic of the last example is how they proved there are more decimal numbers between 0 and 1 than there are integers from 0 to infinity
But doesn't logic also say that for any decimal between 0 and 1, you'll find an integer by dropping the decimal point?
@@okgaming7886 no because 0,1 and 0,01 and 0,001 all will give 1 when you drop the decimal even though they are different numbers
@@ismailsahin3232 fair, but for every case of a leading zero that can be dropped from an integer, there's a decimal with a trailing zero that can be dropped, e.g. .10, .100, .1000 are all .1. So that still should work out even, should it not? Perhaps a better axiom is that you can always reverse it and drop the decimal.
@@okgaming7886 yes but that doesnt mean it will even out, also i think the point was that integers are countable infinity where as decimals are not. When given a 2 integers you know how many integers are there between them where as there is always infinite number of decimals between 2 different decimals.
@@ismailsahin3232 I don't see how it wouldn't. If we can prove there's a rule to convert any unique decimal into an equally unique integer, logic should hold there can't be more of them. But I also don't buy the contradiction that a hotel with infinite rooms could become full. If it's full, it isn't infinite; if it's infinite, it isn't full. This entire problem seems to depend on temporarily forgetting the premise that it's infinite, then remembering it, so what do I know? lol

An engineer enters a burning building and sees a fire extinguisher on a wall.
He grabs it and puts the fire down.
A mathematician enters a burning building and sees a fire extinguisher on a wall.
He just walks out, because there's a clear obvious solution.
This to me seems more like a thought experiment on efficiency, extra rules and assumptions had to be made to come up with a answer.
Im no mathematician, but I would have thought it didnt mater In what way an infinite amount of people arrived, or in how many groups. They all wanted the same thing and could be considered a single entity. Meaning a universal less efficient method could have been used.
Hmm, this won't work because eventually they will get tired of looking. But that is illustrating a flaw in the solutions in the video too. All of them assume that all guests are capable and willing to follow your instructions, and given an infinite number of guests, I think that is guaranteed to not be the case for some of them.
Imagine you go to this hotel, your room number is some absurdly high number. It takes hours to get to it, and you're dead tired once you do. You're about ready to throw yourself on the bed when you hear over the PA: "please move to the room number that is 2 times your current number".

If you couldn’t figure this one out, don’t worry, you’re not alone. When Cantor published his now famous results on cardinality, it was so paradoxical that almost nobody accepted it. But Hilbert did, and created this analogy to help justify it to befuddled minds.
Indeed. Some guys here think they are smarter than Hilbert, Goedel and Cantor together. Maybe they should look up those names and then think again.
Good video and explanation! You also see something similar in limits which have inf/inf form.
It’s funny how this assumes that the guests don’t care about moving from their hotel rooms a crap ton of times
by technicality, it's just to show there would be enough rooms to fit everyone, and the new people could just enter the empty rooms that are confirmed to exist.

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.

How can something be bigger or smaller when… you can just add more numbers… and if there is a limit to that number… it’s not limitless… so it can’t be infinite.
Great explanation guy😂
I was going to make a joke about infinity, but I'll never hear the end of it.
This guy... :)
well done.

Get out
nice dad joke
“This hotel can’t run out of room!”
“Yeah but what if it did?”
....."but it can't tho"
"Yeah but what if it DID??"
repeat x infinity
No what if just tell them to learn about infinity first 😂
Then your question would go on for infinite as so would your doubt of this fact because infinity is as unlimited as the very definition as soon as you recognize how infinity is as it stretches farther than your perception
That's a question for another 'what if'
Lol, good one
Never thought my life would come to the point where I'd be looking at the basic explanation of infinity.
Well, that's one of the explanations why |R| > |Q| (R - real numbers, Q - rational, |R| - roughly, number of numbers in the set of real numbers). We cannot associate each real number with a natural number (just like with the rooms in the video), but we can with rational numbers. Therefore, |N| = |Z| = |Q| < |R|
When the infinite number of infinite buses arrived, gotta admit I felt like giving up on my career as hotel manager.
Lol
Just think of the infinite profit.
Yeah and youre just a manager so youre getting the same wage even though hotel profits are infinite for the owners
Same like …
I really didn’t get his argument there, an infinite number of buses doesn’t change the number of people, 1 infinite number bus has just as many people as an infinite number of buses
As a computer science student this video is so exciting to watch. The ABAB part reminded me of Turing machine
whoever manages to get into room 1 must be the luckiest man out there..
"You have infinite rooms right?"
"Yeah"
"So that means you will never run out of rooms"
"Makes sense"
"Then would i like to get one?"
"No all of them are full"

Just ask the other guest to move in any room that Isnt occupied
@@sandeepvivek6134 no one understands your comment lmao
Guest: Just finished arranging their items in the room.
Manager: Please move down a room.
Guest: AGAIN?!
Imagine living in one of the largest numbered room when the manager asked them to move double that. I hope they have their walking shoes because I didn't see a vehicle in the hotel.
Lol
My guess is they can teleport, at leas then the people at the end won’t be stuck in purgatory.
it would take for literal ever because if it's infinite and each guest moves every time a new guest arrives they would never even get to step into their room.
Imagine moving 100 rooms 😳

accurate response
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.
Moore's law: we need to double the number of mathematicians to solve the problems generated by the previous ones
I feel bad for the guy that has to walk forever just to go to his room that he will never reach
Actually he will one day reach it but its would be soooooo long that it might feel like eternity but it will come eventually. That's how infinity works
The guy waiting an infinity inside the bus to get out, will dream of being able to walk to his room.
The funny part is: no single person would walk for infinity to get to his room! Every single person would have an exact room number, and thus an exact time it would take to get there. The time may be arbitrarily long but always FINITE! That's the beauty of countable infinity, it's so manageable.

@fred McMurray the other end
I would hate that hotel 💀 Imagine being asked to move to another room everytime someone arrives 💀💀
If you leave it frees up a room for another customer
@@ayamelee9020 im on the side of math not the consumer on this one. I’m sorry
That's only if someone arrives AND there's already infinite people there, not just it someone arrives. If there were like 100 then they'd just go to room 101.
Ikr✋💀
@@ayamelee9020 If you were to manage this hotel, you'd probably want to leave most (100% in the limit) guests alone, and there's a very simple trick to do this. 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.
This sounds so good and i would like to be a party to this, is there any way I can speak with her?
At first I thought it was considering for the lifespan of whomever was walking to the next available room, but that quickly went the wayside.
"Imagine theres a hotel with infinite rooms."
"All the rooms are occupied."
*[visible confusion]*
Exactly my thoughts and I still can't get over it because everything that comes afterwards feels like bs.
Because it's countable infinity so there's a bijection then an uncountable infinity appeared and it doesn't have bijection which means it won't fit to countable infinity because it's not fixated
@@slavetzkyrickyjames4305 get out with your math
@@slavetzkyrickyjames4305 tf you mean countable is it really "infinity" then
@@opioidhamster3205 you gonna understand after you finish the school, probably
“Oh just move to the room double your room number.”
“But I’m… at room 9,000,000,000,000,000,000,005.”
"So what? There are infinitely many people in higher-numbered rooms"
He means that the person in that room will walk for a very long time until getting to the right room
Sure, keep walking, either you reach your room or die trying!
“Start walking, bitch.”

@Darth Sidious ice cream 🍨 line will also be infinite
If you eat an infinite amount of food, you will have an infinite mass, which means you will be a black hole with an event horizon that's infinitely large. You won't be in the hotel, the hotel will be in you!
all i care about infinite money
Bag eggs poggers
there's even greater things than that in heaven.
The hotel owner is infinitely rich and infinitely broke at the same time.
Well as long as the resources he gets from a room is higher than the charges, the man is rich
Yes but the overhead. There are infinite costs associated with the hotel
@@caseygust9773 but if he profits from every room then the money infinite would always be higher than the cost infinite
Yes but the overhead to get started always takes some time to recoup, and we are presumably infinitely building new rooms, so, the owner is infinitely in debt
Cantors diagonal is a contradiction in infinity, not a proof of anything.
