I have a different interpretation of this comic than the one in the explanation. See, I think it makes more sense that due to the infinite nature of numbers, it can be said that there may exist one that happens to be a severe cognitohazard, rather than there certainly being one such number in the comic's universe. [[User:HoneyBadger|HoneyBadger]] ([[User talk:HoneyBadger|talk]]) 01:55, 4 September 2025 (UTC)

I found this number years ago, while reading a hexadecimal dump of an image file, and yes, it is just as potent, possibly more so, in hexadecimal. Want to know what it is? It starts (in hex of course) DEADFACEABEDEFACEDAFADEDBADBEADEDBEDAD before going off into more ‘normal’ digits.

SCP nerd here, I think the article should link to a different SCP. SCP-033 isn't really a good example of a cognitohazard, since it affects written/digital storage, not the mind/brain. [https://scp-wiki.wikidot.com/scp-012 SCP-012] for example would be a closer fit. (CW: somewhat graphic self harm) --[[User:Muno|Muno]] ([[User talk:Muno|talk]]) 04:45, 4 September 2025 (UTC)

If one supposes that reading the cursed number inside another number is also bad, then for you to have at most a 1/2 chance of reading it in a string of numbers with the bounds given in the comic, you would have to read 1.8*10^21 digits strung together [[User:TheTrainsKid|TheTrainsKid]] ([[User talk:TheTrainsKid|talk]]) 05:15, 4 September 2025 (UTC)

3137: Cursed Number

2025-09-04T20:43:43Z

Tsgsh:

{{comic
| number = 3137
| date = September 3, 2025
| title = Cursed Number
| image = cursed_number_2x.png
| imagesize = 388x449px
| noexpand = true
| titletext = Another group of mathematicians is working to put an upper bound on the number, although everyone keeps begging them to stop.
}}

==Explanation==
{{incomplete|This page was created in a CURSED YEAR. Don't remove this notice too soon.}}
In the universe of this comic there exists some number that, through unknown means, is extremely harmful to the human mind to read it - an {{w|information hazard}}. Dangerous pieces of writing like this are a fairly common trope in speculative fiction, such as the {{w|Necronomicon}} in the {{w|Cthulhu Mythos}}, [https://scp-wiki.wikidot.com/scp-033 cognitohazards] in the {{w|SCP Foundation}}, and {{w|Monty Python}}'s {{w|The Funniest Joke in the World|Funniest Joke in the World}}. It is also very similar to the concept of an {{w|illegal number}}.

Naturally, the mathematicians of this world are doing their best, in the interest of public safety, to keep this number away from as many human eyeballs as possible. Through some process they have figured out the number is at least 22 digits long. Numbers this large (greater than a 1022, or 10 sextillion) are extremely unlikely to be found in the day-to-day lives of non-mathematicians (and almost all mathematicians); even if a person spent their entire lives looking at random strings of 22 digit numbers flashing by every millisecond, for a 100 year lifetime, they would still only have about 3 in a (short) trillion chance of seeing the number. Because of the low risk, public officials have deemed it safe for people to go about their daily lives reading numbers again.

Despite this, there are some instances of large numbers (more than 21 decimal digits) that may be encountered relatively frequently. IT professionals may encounter "{{w|Universally unique identifier}}s". These are 128 {{w|bit}} binary numbers requiring up to 39 decimal digits to display. However, many people who encounter a UUID may not realise that it is a number because they are represented as 32 {{w|hexadecimal}} digits, where each "digit" (0-9, followed by a-f) represents a value between 0 and 15. This begs the question: "is the Cursed Number cursed in all (possible) representations, or only in decimal"? Another "everyday" large number that could be encountered by people who are neither mathematicians nor IT professionals can be found in the settings of a computer or mobile phone. An {{w|IPv6_address}} is another 128 bit binary number that may be assigned to devices connected to a network and displayed in a form such as `fe80::0123:4567:89ab:cdef`. Although few people would recognise it as a number{{citation needed}}, this example corresponds to the number 338,288,524,927,261,089,654,100,882,370,564,181,487, which is not cursed.{{citation needed}}

In the title text another group of mathematicians are trying to narrow down the number's identity even further. The more attributes of the cursed number the mathematicians identify, the easier it is for someone with morbid curiosity or someone researching more attributes of the number to discover the number themselves and get their mind damaged. This includes the researchers themselves, as they are now willingly going above the lower safe limit, increasing their chances of encountering it accidentally. Furthermore, the cursed number may appear as part of another number; for example, 223 appears as part of 2237. Worse, if the number could be determined in some controllable way that didn't necessarily expose its discoverers, it might be used as a weapon. This echoes concerns about knowledge gained from research on nuclear forces having been used to create atomic weapons. This was also how the Funniest Joke in the World was used in Monty Python.

Through some process they have figured out the number is at least 22 digits long. Numbers this large (greater than a 1022, or 10 sextillion) are extremely unlikely to be found in the day-to-day lives of non-mathematicians (and almost all mathematicians); even if a person spent their entire lives looking at random strings of 22 digit numbers flashing by every millisecond, for a 100 year lifetime, they would still only have about 3 in a (short) trillion chance of seeing the number. Because of the low risk, public officials have deemed it safe for people to go about their daily lives reading numbers again.

Despite this, there are some instances of large numbers (more than 21 decimal digits) that may be encountered relatively frequently. IT professionals may encounter "{{w|Universally unique identifier}}". These are 128 {{w|bit}} binary numbers requiring up to 39 decimal digits to display. However, many people who encounter a UUID may not realise that it is a number because they are represented as 32 {{w|hexadecimal}} digits, where each "digit" (0-9, followed by a-f) represents a value between 0 and 15. This begs the question: "is the Cursed Number cursed in all (possible) representations, or only in decimal? Another "everyday" large number that could be encountered by people who are neither mathematicians nor IT professionals can be found in the settings of a computer or mobile phone. An {{w|IPv6_address}} is another 128 bit binary number that may be assigned to devices connected to a network and displayed in a form such as `fe80::0123:4567:89ab:cdef`. Although few people would recognise it as a number{{citation needed}}, this example corresponds to the number 338,288,524,927,261,089,654,100,882,370,564,181,487, which is not cursed.{{citation needed}}

In the title text another group of mathematicians are trying to narrow down the number's identity even further. The more attributes of the cursed number the mathematicians identify, the easier it is for someone with morbid curiosity or someone researching more attributes of the number to discover the number themselves and get their mind damaged. This includes the researchers themselves, as they are now willingly going above the lower safe limit, increasing their chances of encountering it accidentally. Furthermore, the cursed number may appear as part of another number; for example, 223 appears as part of 2237. Worse, if the number could be determined in some controllable way that didn't necessarily expose its discoverers, it might be used as a weapon. This echoes concerns about knowledge gained from research on nuclear forces having been used to create atomic weapons. This was also how the Funniest Joke in the World was used in Monty Python.

In the universe of this comic there exists some number that, through unknown means, is extremely harmful to the human mind to read it - an {{w|information hazard}}. Dangerous pieces of writing like this are a fairly common trope in speculative fiction, such as the {{w|Necronomicon}} in the {{w|Cthulhu Mythos}}, [https://scp-wiki.wikidot.com/scp-033 cognitohazards] in the {{w|SCP Foundation}}, and {{w|Monty Python}}'s {{w|The Funniest Joke in the World|Funniest Joke in the World}}. It is also very similar to the concept of an {{w|illegal number}}.

Naturally, the mathematicians of this world are doing their best, in the interest of public safety, to keep this number away from as many human eyeballs as possible.
