==Explanation==
{{incomplete|Created by a HIGH-PITCHED HUM GENERATOR THAT WAS LAST MENTIONED EXACTLY 1258 COMICS AGO - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
A {{w|Distribution board}}, referred to as a "breaker box" here and commonly referred to as a "fuse box", "breaker panel", "DB box", and many other names, is a metal box inside a building that is attached to a wall, usually in some maintenance area, containing several {{w|circuit breakers}} that let power through to various parts of the building. A circuit breaker is an electrical switch, usually in the form of a small lever, that will physically open if too much power is flowing through, as might be the case if a fault occurs, in order to protect appliances.

In most breaker boxes, each individual breaker is labeled to let the operator know what that specific breaker controls. A breaker will usually control something like the outlets or lights in a certain room, or some large appliance. In houses that have been rewired multiple times(or are poorly wired), this can quickly become overcomplicated with seemingly random connections. The comic satirizes this, with multiple breakers "controlling" arbitrary things that may be impossible to hook a breaker up to, getting progressively more absurd to the point of disabling certain laws of physics as the switches get lower.

The title text is about causality. Turning off the circuit breaker using the circuit breaker may lead to a loop, as the disabled breaker can no longer disable itself, leading to it turning back on, etc. Turning off causality would prevent this loop as causes would no longer have effects.

===Table of the breakers labels===
{|class = "wikitable"
! Label next to breaker !! Explanation !!   !! Label next to breaker !! Explanation
|-
| Kitchen Lights || The lights in the kitchen. || || A whirring fan you didn't realize was on until now || The AC in a building usually creates quiet white noise from fans, which people usually do not hear until they become aware that there is a sound. Other appliances, such as fridges or home servers can have similar effects.
|-
| Living room lights || The lights in the living room. || || Dishwasher || The dishwasher.
|-
| Porch lights || The lights on the porch. || || Dishes || At a glance this could pass for a normal thing to be next to a breaker, despite dishes not requiring electricity. This might, however, actually be referring to an array of satellite dishes, but given how the switch for the dishwasher is immediately above this is most likely not the case.
|-
| Bathroom lights and one surprise mystery outlet somewhere || This controls the lights in the bathroom, but also a random outlet. This kind of situation can often occur, where the layout of the house and the wiring can mean that it is a sensible or convenient design decision from an electrician's perspective to wire seemingly logically unrelated things to the same circuit, but nonetheless is confusing to the homeowner when reviewing the breaker options. || || Hallway lights || The lights in the hallway or hallways.
|-
| North-facing appliances || Despite the impossibility of determining which way an appliance is facing, ignoring how you would even define that, without having a magnetic compass inside every appliance, and having all of those appliances be hooked up to one breaker, this apparently routes power to every appliance that faces north. It is unclear how strict this is as well - it could be as lax as northeast to northwest, or even as strict as {{w|Points of the compass#32-wind compass rose|north by east to north by west}}.|| || Hallway outlets || The outlets in the hallway or hallways.
|-
| Bathtub drain light || Bathtubs typically do not have drain lights, but this breaker provides power to that and only that. || || Hallway floors || This could pass for a normal breaker at a glance, given the two above and in some buildings there are floor outlets. This could also potentially refer to turning off the power for all the hallways on a given floor. Floors in and of themselves do not typically require power, but if they act differently when not powered is unknown. A simpler explanation is this just electrifies the floors, which is not usually desirable,{{citation needed}} but may be barely noticeable in this case when considering this breaker has been on the entire time. Unless the hallway is equipped with electric underfloor heating.
|-
| Appliances whose names contain the letter "F" || Another breaker that could theoretically be done despite the tremendous difficulty in doing so. Electrical systems do not carry data about names, and it is unclear how it would even get this information, if it would change depending on locality, if it uses the common name for something or the full name, how it would work in different languages, and so on. || || Social media || All of social media. This may be a reference to 'digital detoxes', where people turn off / delete / deny themselves access to all their social media apps, in the hopes that this will provide some improvement to their quality of life. It couls also be a callback to [[908: The Cloud]]. Since most social media platforms are a centralized services, it would be theoretically possible to hook up a switch to the main power supply of every server building at once, given some extremely long wires, a breaker capable of handling the abhorrently massive electric load, and agreement from every social media provider(optional).
|-
| Hot water heater || The heater for hot water. || || State law || It is unclear which state's laws this controls, but why they require power to operate is unknown. This may just be for enforcement of the laws, instead of nullifying every single one whenever it is turned off. Additionally, since Randall lives in Massachusetts, it's very likely this refers to the same state. Turning off the breaker could result in a state similar to martial law.
|-
| Regular water heater || The heater for regular water. Presumably, given the above switch, this is for heating lukewarm or cool water, while the above is for keeping it warm and acting as a storage medium. This could just be accomplished with a single water heater with the capacity of two, but it may be useful for getting a lot of adequately hot water quickly when only half a tank's worth is needed. Alternatively, this may imply that this heater is for heating water that is not yet hot, whereas the heater above is, unexpectedly and somewhat pointlessly, for heating water that is already hot.|| || Federal law || The ramifications of nullifying every federal law ever are immense, but this may still be for enforcement, like the above.
|-
| Outlets in rooms that it's normal to eat pizza in || This controls every outlet in rooms that it's normal to eat pizza in. This implies that the living room is not a room it's normal to eat pizza in, since those are on a different breaker. On the other hand, that breaker specifically specifies that it controls the living room '''''lights''''', but disregarding this, it's very likely it may still include the living room, seeing as the other switches fail to have any sort of constraints. Other eligible rooms would probably include the dining room, kitchen, and/or bedroom, but would be dependent on the inhabitants / regular visitors of the house (for example, they may regularly eat their pizza in the bathroom). || || Second law of thermodynamics || Turning off a physical law, especially the second law of thermodynamics, would be catastrophic, since the rest of the laws of physics would most likely follow suit once one collapsed unless they are held in place by other laws.

This law of physics was also explored in the What If? article [https://what-if.xkcd.com/145/ Fire From Moonlight]. As explained by Randall in this article, the second law of thermodynamics states that you cannot transfer heat from one location A to make another location B any hotter than location A, unless you expend some form of energy in doing so.
|-
| High-pitched hum generator || Controls a high-pitched hum generator. This is a call-back to [[1590: The Source]]. || || Friction || Again, turning off a physical law would be catastrophic, but turning off friction may not destroy reality. If it was turned off, however, many things would become incredibly unsafe or useless, while others would have increased efficiency. The benefits, however, would be negligible in comparison to how many systems would collapse instantly, such as ratchets, car tires, standing up, or just things staying still in general. Being in a frictionless environment (and a vacuum, as physicists love...) was the subject of [[669: Experiment]].
|-
| The solution to the cryptogram below: || A cryptogram is a puzzle where a sentence has been encoded using a cipher, usually very simple, and the goal is to determine the cipher used and recover the original sentence from the encoded one. This may be literal, as in the solution is "circuit breaker", but it also may be controlling the ability to know what the solution is or if it can be discovered. || || Gravity || If this was turned off, the Earth would explode, along with all other celestial objects. Planets and stars have extremely high internal pressure that is constantly in conflict with gravity. Every part would be forced outward at incredibly high speeds, and any object that requires gravity would simply not be able to form. Of course, this might also just make everything in the house weightless, which has much less disastrous consequences and would probably actually be pretty cool.
|-
| Bugs || This could either refer to software bugs or actual bugs, both of which do not make much sense to be able to turn off. If this does refer to actual bugs, it may be a reference to [[2753: Air Handler]].|| || Circuit breakers || If this was turned off, it would presumably turn off all power in the house since no breaker is supplied or supplying power any more. (Most houses have a main circuit breaker that provides this functionality.) However, if this circuit breaker disables the ability to toggle circuit breakers, you would not be able to turn this circuit breaker back on.

"Fatal to get a big one in your body"? Even medium-sized black hole is significantly bigger than human body, how would it fit inside? That said, being even just near any black hole is fatal: if it's not big enough to eat you, it's small enough to release dangerous amount of radiation. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 21:20, 20 October 2023 (UTC)

:Not necessarily if it's small enough. We don't know what would happen to a black hole of Planck mass. If it's stable, then it wouldn't really affect you, because it would be unable to radiate and also unable to accrete matter gravitationally. It would orbit the Earth as a WIMP doing practically nothing. Even if it's unstable and evaporates while releasing a colossal amount of energy (about 1.2 × 10¹⁶ TeV), it might not be a problem, because the particles might be moving too fast to transfer any meaningful amount of energy to your body. They would basically just pass right out of you with no effect. But of course we don't really know.

BH clearly isn't Freudian. For the {{w|File:Structural-Iceberg.svg|Iceberg of the Mind}}, the most important part is the 90% of it that is ''hidden''.

Does anyone have knowledge of aerogels being infused with helium? I'm assuming it wouldn't be too outlandish to do so, but honestly don't have a lot of experience with them. [[User:Fifteen12|Fifteen12]] ([[User talk:Fifteen12|talk]]) 14:39, 15 September 2023 (UTC)
:It'd be complex. Most are 'open cell', so need an external coating. Or "pockets of helium" could mean small helium-filled ballonettes embedded within aerogel; being uniformly externally supported by the aerogel, these pockets could be structurally less bulky than traditional bladders of lift-gas (still need to be impermeable, but without the inflate-stretching of rubber, can be a more 'delicate but efficient' material, perhaps [https://pubs.aip.org/physicstoday/online/27257/Graphene-displays-unexpected-permeability graphene]). You could (also?) coat the outside of the aerogel, but adding an arbitrarily large envelope of such a membrane around helium-infused aerogel and then adding more (normally aerated) aerogel onto the outside as additional buffer/structural precaution might be wise(r), as you go ship-hunting...

What aerogel would break down in water? From what I've seen, I thought most aerogel was made of silica? (There's actually no gel left in an aerogel; the gel is replaced by gases.)

"God himself couldn't sink this ship." That's just giving Murphy a temptation far too great to resist.

Wouldn't helium be a better choice for the low-mass pursuit iceberg?

:Assume you meant "Wouldn't hydrogen be a better choice...", from context/rest of your argument.

I did some calculations, based on the data that, at 0 degrees C and sea level, a cubic meter of either hydrogen or helium will lift 1 kilogramme (close enough) of mass, and the average Iceberg Alley iceberg has a mass of 100,000 tonnes. I worked out that, to lift that "average iceberg", one would need a cube of lifting gas 500 m (five average USA city blocks) per side. If this is correct, the challenge of fitting that cube of gas inside the average iceberg is (ahem) nontrivial. [[Special:Contributions/172.69.34.40|172.69.34.40]] 17:45, 16 September 2023 (UTC)

2825: Autumn and Fall

2023-09-06T22:43:41Z

{{comic

| image = autumn_and_fall_2x.png
| imagesize = 392x212px

}}

==Explanation==
{{incomplete|Created by a FALLING BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

{{w|Autumn}}, also known as "fall" in the United States, is the season between summer and winter. These terms are used interchangeably, but Randall in this comic treats them as separate seasons. His timeline uses "autumn" as the season between the end of summer and the "{{w|September equinox|fall equinox}}", and the season of "fall" as the period after that until winter. Of course, while many different parts of the world use different ways of reckoning the {{w|seasons}} (eg, a two-season system in the tropics or a six-season system in South Asia), nowhere uses the type of five-season system shown in the comic.{{Citation needed}}

The comic depicts two of the three possible boundaries, for any given hemisphere, for the recognised end of summer.
* Some treatments of the seasons (not shown) treat the summer solstice very much as "midsummer", and all other seasons also more or less equally straddling their own equinoxes/remaining solstice, putting the seasonal boundaries half way between each of these astronomically significant points.
* For others, the equinoctial/solstitial dates are used for the changeover time, so that autumn/fall starts upon the equinox (shown) and ends at the astronomically shortest day which is then the start of winter. This system tends to be traditional where the annual warming and cooling of the climate significantly 'lags' the solar calendar.
* Meteorological seasons are handily aligned to months, for administrative reasons. Spring is March through May, summer across June to August, the September start (to the close of November) is as illustrated, leaving winter to be covered by December and on until the end of the following February. Or shifted round by two of the triples for the southern hemisphere.

The title text makes fun of the transatlantic difference in terms, as it claims one must ''reverse'' these two distinct season names. The term "autumn" is, in reality, the word overwhelmingly used in the UK for the season commonly (but not exclusively) refered to as "the fall" in the US. The latter is rarely used 'natively' in the UK, although it will usually be understood. Its use within Britain is rare beyond forming the handy mnemonic of "spring forward, fall back", which helpfully refers to how/when British Summer Time (UTC+1) temporarily replaces Greenwich Mean Time (UTC±0).

1849: Decades

2023-07-17T12:58:48Z

172.71.242.62: /* Explanation */ Saw this news article, decided it might work as a citation/caveat for here, and for the 'fix' of spelling. (Perhaps it's just too British, in all respects. And we, in turn, don't use "aught" for "zero", very much at all.)

{{comic
| number = 1849
| date = June 12, 2017
| title = Decades
| image = decades.png
| titletext = In the 90s, our variety radio station used the tagline "the best music of the 70s, 80s, and 90s." After 2000, they switched to "the best music of the 80s, 90s, and today." I figured they'd change again in 2010, but it's 2017 and they're still saying "80s, 90s, and today." I hope radio survives long enough for us to find out how they deal with the 2020s.
}}

==Explanation==
From the 1960s to the 1990s, it was common to group eras by decades. Fashion, music, and other cultural trends that changed relatively quickly were often defined by those decades. People casually and commonly referred to "the sixties", and so on, to separate these periods.

This pattern broke down after 1999, because it didn't naturally lend itself to an analogous phrase for the year from 2000-2009. A number of different terms have been proposed and used: "the {{w|Aughts}}", and "[https://www.bbc.co.uk/news/newsbeat-66199129 the noughties]" had been used for 1900-1909, but have an archaic flavor that may not work for everyone. "The "{{w|2000s}}" and "the millenium" are ambiguous and clunky. None of these terms ever became popular enough to become a consensus term. Similarly for the period from 2010-2019, terms like "the 2010s" and "the teens" have been used, but not widely accepted.

The practical upshot of all of this is that verbally splitting time periods into clear decades simply became less obvious for the periods since 2000. While people still refer to earlier time periods by decades, it is far less common to do so when referring to recent years. The roll-over text gives the example that we still refer to "music of the '80s and '90s" (although the comic omits the apostrophes that might normally indicate the missing century digits), but rarely refer to "music of the 2000s" or something similar.

The time-line in the comic stretches into the future (as of the time of publication), and uses question marks to present uncertainty over whether the decade-grouping trend will return in the 2020s. On the one hand, such was a well-established custom, and we once again have clear language for it. On the other hand, after largely abandoning the custom for 20 years, it is far from certain that people will adopt it again.

What isn't mentioned in the comic, but may be relevant, is that, in the absence of those decade categories, it has become more common to refer to time periods and the people who grew up in them by somewhat arbitrary generational categories: Baby Boomers, Generation X, Millenials, Gen Z, and so on. This has provided an adequate substitute, since youth culture in the 2000s and 2010s has been more commonly defined as {{w|Millennials#Cultural_identity|millennial culture}}". There are drawbacks to this (both because the terms are more loosely defined, and because they often come with negative connotations), but these trends may have become sufficiently ingrained that they could displace the older decade-based divisions.

The title text gives the specific example of [[Randall]]'s local radio station dividing music by decades, and points out they simply started talking around the decades from 2000 to 2019. He implies that whether they resume this pattern in the 2020s will be a good indicator of whether this speech pattern will resume, but expressed doubt whether radio will last long enough to find out. This is a jab at the radio industry, which has been in decline for a long time as it has faced increasing competition from other communications technologies. While it is unlikely that the radio industry will cease to exist in the near future, further decline seems probable.

Twenties were discussed again later in [[2249: I Love the 20s]].

:It's weird how for 20 years we stopped grouping our cultural memories by decade because "2000s" is ambiguous and and "Aughts" and "Teens" never really stuck.

==Trivia==
*Randall has by mistake, written "and and aughts" in the caption for this comic, instead of "and aughts".

172.71.242.62: Clarification that I get the joke

Same person.

Why is he only using John's first name when talking about him, as if Surf King should know who that is, when it's clear they've "never met"?
Shouldn't it be: My phone keeps wanting to merge you with my friend John Smith? [[Special:Contributions/172.71.178.30|172.71.178.30]] 07:46, 13 July 2023 (UTC)

== Google search link ==

A couple of times, recently, you provided a Google search link to something. I don't like following those (with their "q=..." stuff and hangover metadata in other POST data) when you could perhaps give the direct link you intend instead?

i.e. right-clicking on the Google page's item and copying that link is wasteful (and not ''always'' correct), you should instead follow the link you intend and then copy the true address (if proven to be what you wish) from the address-bar. And, even then, best to cut away any "&referer=..." type stuff (and retest the cut down link!) so that everyone who follows you has a bare-bones link that works without having to mess with reconstructing the metadata that means "<nowiki>http://whatever.com/foo/bar/baz.html#indexpoint</nowiki>", or howsoever it should resolve.

Just a tip. To streamline and not unneccessarily obfuscate the use of your contributions... [[Special:Contributions/172.70.91.77|172.70.91.77]] 15:15, 15 December 2022 (UTC)

''Probably'' you could just confirm these claims, ''before'' making them? It seems easy enough to do, and you seem to have the time to do it. [[Special:Contributions/172.71.242.141|172.71.242.141]] 23:25, 12 January 2023 (UTC)

==Help==
I need your help creating these pages and uploading the pictures I needed. Please, please, you know that we are close friends IRL. --[[User:ChristmasGospel|ChristmasGospel]] ([[User talk:ChristmasGospel|talk]]) 20:34, 20 January 2023 (UTC)
:Look, [https://www.explainxkcd.com/wiki/index.php?title=User_talk:ColorfulGalaxy&curid=25878&diff=305104&oldid=305057 this is clearly a stupid move] to try to look legitimate. If you're truly IRL friends then it could have waited for an IRL meeting (or whatever other social media blinks you have), at which point your 'friend' could have provided a lot more practical help without waiting for such silly messages. Laughable, really. But do as you're going to do, I'm sure I can't stop you from going through with this clear pretence to whatever end you're leading up to. And no apologies if I'm wrong, just pity.

== So many broken links on your User page. ==

I presume you are fully aware that pretty much everything you're linking to on your User page is a dead link. Both internal and external ones (even inter-wiki). I presume you are also aware that your quite obvious use of multiple alts and logins is very visible. Either that, or you are remarkably unaware of third parties (with bad MOs) making so many terrible edits in some quite definitely targetted way.

Either way, you might want to just get things working how you want to get things working, and bring it all to fruition, and not leave us all hanging... [[Special:Contributions/172.70.85.57|172.70.85.57]] 13:39, 4 March 2023 (UTC)

:So it would seem that [https://www.explainxkcd.com/wiki/index.php?title=2293:_RIP_John_Conway&diff=308507&oldid=308506 this is you], as well, CG. The question we must all be wondering is why? Quite an army of alt-logins you seem to be building up, and the actions of the less nicely behaving ones (you know which I mean) don't exactly make me feel unconcerned about it.
:It wouldn't be so bad if you were doing useful edits or actually made your Conlang links into a working (and ideally relevant) reference system that we could all enjoy. But you seem to have no intent to do that. [[Special:Contributions/172.70.85.224|172.70.85.224]] 06:38, 14 March 2023 (UTC)
::The neography reproducing project involves uploading a lot of images, mostly vector images.

:::Your explanation makes no sense... Your neography clearly has no real connection to xkcd. The images required here should be xkcd ones (or derived material). You haven't shown absign of contributing any of those. One account (sufficiently validated) is enough to upload, as you'll already know. There's no connection to fandom.com, at all. That's not even a local category (like almost every other link around here, you leave it redlinked). You don't need to create many special logins for anything you have done (for the most part, I can do everything worthwhile for the site with no account at all, and you have a clear history of doing unworthwhile things with many accounts, a number of them now banned.
:::So I call bullshit. I've seen others try to help your 'new users' out, with things you've messed up (done it myself, see above) just to be ignored, and then it becomes clear that you continue with whatever game you think you're playing, under an expanding host of aliases.
