:White Hat: When you have eliminated the impossible, whatever remains, however improbable, must be the truth.&lt;br /&gt;
[Close-up of Cueball's head.]&lt;br /&gt;
:Cueball: What about the possibility that you forgot to eliminate a possibility?&lt;br /&gt;
:Cueball: Or that you eliminated one incorrectly?&lt;br /&gt;
:Cueball: Both of those remain, too.&lt;br /&gt;
[Zoom back out to show both parties. Cueball is holding his arms out.]&lt;br /&gt;
:White Hat: You're being pedantic.&lt;br /&gt;
:White Hat: It's just a general rule for deduction.&lt;br /&gt;
:Cueball: But it's a ''bad rule.''&lt;br /&gt;
[Cueball is now holding up one finger.]&lt;br /&gt;
:Cueball: How often have you thought, &amp;quot;I can't find this thing, and I've searched the whole house. The only place I haven't looked is the car, so it ''must'' be there.&amp;quot;&lt;br /&gt;

{{incomplete|This page was created by an arthropod who will get 10 pointy things to zap a metal box and tell it stuff.. Don't remove this notice too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic pokes fun at spiders, which have a very unusual way of catching prey.&lt;br /&gt;
&lt;br /&gt;
The first arthropod refers to isopods, while the second refers to scorpions.&lt;br /&gt;
&lt;br /&gt;
Note that evolution in real life does not work the way the comic implies, as creatures cannot decide which direction in which to evolve.{{citation needed}}&lt;br /&gt;
&lt;br /&gt;
[[:Category:Spiders|Spiders]] are a recurring theme on xkcd.&lt;br /&gt;
&lt;br /&gt;
The hovertext mentions the eusocial insects, another group of arthropods. They are notable for not &amp;quot;minding their own business&amp;quot;, as their ancestor arthropod apparently expects.&lt;br /&gt;
&lt;br /&gt;
Eusociality has evolved multiple times in the Hymenoptera alone, as well as in termites. There is no arthropod species that is the ancestor to all the eusocial arthropods and no others.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created by a youTuber without internet Don't remove this notice too soon.}}&lt;br /&gt;
This comic jokes about a familiar pattern in YouTube comment sections: people often leave comments announcing the year they are watching a video. These comments serve no practical purpose, but are nonetheless a harmless compliment implying the video is &amp;quot;timeless&amp;quot; and a memory worth revisiting.&lt;br /&gt;
&lt;br /&gt;
The comic reframes this behavior as the actions of confused time travelers. Since YouTube comments frequently include statements like “Anyone else here in 2017?” or “Watching this in 2025,” the strip humorously suggests that people displaced in time use comment sections to confirm what year they’ve landed in.&lt;br /&gt;
&lt;br /&gt;
The title text escalates the joke by placing a commenter in 1954, decades before YouTube existed. This absurd anachronism implies that the time traveler’s last jump went so badly that it altered the timeline enough for YouTube to exist in the mid-20th century. Rather than questioning the impossibility of the situation, the time traveler treats it casually, blaming themself for breaking history.&lt;br /&gt;
&lt;br /&gt;
The humor comes from:&lt;br /&gt;
&lt;br /&gt;
Recognizing a real, mildly annoying internet habit&lt;br /&gt;
&lt;br /&gt;
Treating YouTube comments as a universal, cross-timeline reference point&lt;br /&gt;
&lt;br /&gt;
The understated admission that history itself may be broken, delivered with the same casual tone as typical comment spam&lt;br /&gt;
&lt;br /&gt;
Like many XKCD comics, it mixes everyday internet culture with science-fiction concepts, using a dry, matter-of-fact tone to make an absurd premise feel oddly reasonable.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created by an A frog stuck on mars. I have added a bit about the drawing. It is important I think that the planet with the frog has exactly the r&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt; radius. This means the frog cannot escape but just barely. Is there a physics relation behind the fact that the jumps height seems to be very close to the radius of the planet, i.e. r&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt;? Also Can someone calculate the size and mass of the largest object from which a champion frog can achieve escape velocity? Are there some named asteroids that are of sow low a mass that it would be possible for frog to jump of? (Of course there are some small enough... but do any of them have real names, like the one named after Randall)? Don't remove this notice too soon.}}&lt;br /&gt;
The {{w|Schwarzschild radius}} is essentially the size of a {{w|black hole}} -- the maximum distance from the center where gravity is so strong that light can't escape. &lt;br /&gt;
&lt;br /&gt;
It is part of a solution to {{w|Einstein's field equations}}. It is usually calculated as the following:&lt;br /&gt;
:''r'' = (2*''G*M'') / ''c''&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;,&lt;br /&gt;
where ''G'' is the {{w|gravitational constant}}, ''M'' is the mass of the object, and ''c'' is the {{w|speed of light}}. &lt;br /&gt;
&lt;br /&gt;
If ''M'' were the mass of the {{w|Earth}}, it would give the Schwarzschild radius for the Earth, which is about 9 mm. (If all of Earth's mass were compressed into a sphere of a bit less than 2 cm in diameter, it would become a black hole.)&lt;br /&gt;
&lt;br /&gt;
The comic suggests a more useful radius: the ''Jumping Frog radius'' ''r&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt;'', which is the size of a &amp;quot;planet&amp;quot; such that its gravity keeps a champion {{w|Frog jumping contest|jumping frog}} from being able to achieve {{w|escape velocity}}. Thus [[Randall]] has instead of ''c'', the 299,792,458 m/s speed of light, used a much smaller value of 4.5 m/s, to represent the maximum speed of a jumping frog. It is possible that Randall got that value from [https://www.researchgate.net/publication/5661154_Explosive_Jumping_Extreme_Morphological_and_Physiological_Specializations_of_Australian_Rocket_Frogs_Litoria_nasuta this paper], which on page 179 puts an upper limit on the maximum velocity of adult {{w|Striped_rocket_frog|Australian rocket frogs}} at 4.52 m/s.&lt;br /&gt;
&lt;br /&gt;
The drawing to the right of the formula shows a planet with exactly the radius ''r&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt;''. Thus the frog can jump really high compared to the planet's size (in this case about as high as the planet's radius), before it unavoidably falls back down, since the small planet is just massive enough to prevent the frog escaping.&lt;br /&gt;
&lt;br /&gt;
The title text points out that the ''r&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt;'' of the Earth is about 1.5 light days, which is about 7 times the distance to {{w|Pluto}} (compare to the 9 mm Schwarzschild radius). Since Earth's radius is much smaller than this, no frogs will be able to escape, so all frogs that stray into Earth's gravitational well would collect here on Earth. As far as we know, all the frogs in the Solar System are on Earth{{Citation needed}}, so the data apparently matches the theory. However, the reasoning is incorrect, as many other astronomical bodies in our solar system also have ''r&amp;lt;sub&amp;gt;jf&amp;lt;/sub&amp;gt;'' greater than their physical radius. If a frog were to be on any of those other bodies, it wouldn't be able to jump away to fall to Earth. A flawed argument neither supports nor refutes the conclusion, although it is true as far as we know that all frogs in the solar system do live on Earth.&lt;br /&gt;

:[The drawing to the left shows a very small planet with the radius indicated with a labeled dotted arrow pointing from the center straight up to the edge of the planet. A frog is shown jumping on the surface. This is indicated with a parabolic dotted line going from a frog sitting on the surface near the top of the planet, up to the frog shown soaring through the air with its limbs stretched out about as high above the surface as the planet's radius. At this point the frog is making a sound. Then the dotted line goes down to about a quarter of the way around the planet where the frog lands making a noise, with lines around the frog representing the impact.]&lt;br /&gt;

:More practically useful than the Schwarzschild radius, the '''''Jumping Frog Radius''''' is the radius at which an object's gravitational pull is so strong that even a champion jumping frog can't escape.&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|This page was created BY A FISH WITH THE WEIGHT OF THE SUN. Don't remove this notice too soon.}}&lt;br /&gt;
[[Ponytail]] and [[Beret Guy]] are fishing in the middle of a body of water, and Beret Guy has hooked a rock. Similarly to the common meme that sees people catching objects such as boots and shopping trollies, he exclaims that it &amp;quot;feels like a big one&amp;quot;. Fishers may judge the size of a fish by the amount of resistance they feel on the line, and such objects would provide an unusually high level of resistance (also, the boat would be bulled down if he reeled, so he could only tell that its downward pull is greater than the boat's buoyancy.). In this case, though, Beret Guy can apparently feel that it must be &amp;quot;at least 10&amp;lt;sup&amp;gt;24&amp;lt;/sup&amp;gt; kilograms&amp;quot; — that is, an object the size of the Earth in its entirety, whose mass can be estimated at approximately 6.0x10&amp;lt;sup&amp;gt;24&amp;lt;/sup&amp;gt; kilograms (~13.1x10&amp;lt;sup&amp;gt;24&amp;lt;/sup&amp;gt; pounds at standard gravitational acceleration of the Earth).&lt;br /&gt;
&lt;br /&gt;
Catch-and-release sizes restrict what sizes of catch of various species can be kept, generally to protect stocks. There may be minimum sizes (to protect young fish and ensure that they can reach mature reproductive age) or maximum sizes (to protect existing breeding populations). Apparently, the Earth is large enough to be kept, suggesting that smaller planets and other bodies might be considered immature, and that they might be expected to grow to 'adult' planet size.&lt;br /&gt;

If you fail your task, you spend hours troubleshooting the website. If you succeed with the task or your troubleshooting, you end in the good ending, where you get a good job message.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Bad ending:&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If you fail either troubleshoot, you stop you work and call the website's customer service. They say, &amp;quot;Did you know you could do this all more quickly and easily on our website? just go to WWW. ...&amp;quot; however, you were on the website, and this angers you.&lt;br /&gt;

&lt;br /&gt;
This image presents a core sample taken by a slightly chaotic team of geologists. Contained within it are fairly normal ground matter such as &amp;quot;topsoil&amp;quot; and &amp;quot;granite&amp;quot; but also such things as &amp;quot;bottomsoil&amp;quot;, which has no IRL parallel, parts of subway cars, arms of a spelunker most likely amputated by the sample, a &amp;quot;balrog&amp;quot; wing (referencing a fictional animal which first made an appearance in [https://www.explainxkcd.com/wiki/index.php/730:_Circuit_Diagram], and after diving through the core of the earth, the home of someone else. It first starts with cement, the foundation, floorboards and carpet (either a carpeted floor or a decorated floor), and then the posessions&lt;br /&gt;
&lt;br /&gt;
The title text humorously refers to a &amp;quot;rival team&amp;quot; and their coring equipment - implying that with the correct angle you can muddle with their own coring experiment, which, outside of cold war-type pettiness, is not considered a constructive approach to science.&lt;br /&gt;

&lt;br /&gt;
This image presents a core sample taken by a slightly chaotic team of geologists. Contained within it are fairly normal ground matter such as &amp;quot;topsoil&amp;quot; and &amp;quot;granite&amp;quot; but also such things as &amp;quot;bottomsoil&amp;quot;, which has no IRL parrelel, parts of subway cars, arms of a spelunker most likely amputated by the sample, a &amp;quot;balrog&amp;quot; wing, and afte rdiving through the core, the possessions of an angry homeowner.&lt;br /&gt;

&lt;br /&gt;
The comic shows a directional drilling rig which will drill a hole through the lithosphere to create a borehole with a constant curvature.&lt;br /&gt;
&lt;br /&gt;
However instead of using it for scientific study, the comic suggests that this borehole will actually be so that the Earth can get a piercing like a giant ring.&lt;br /&gt;
&lt;br /&gt;
The title text plays on the normal warnings about piercings, with some lava around the piercing, but watch out for earthquakes, similar to instructions that some redness is normal, but watch out for infection.&lt;br /&gt;
