:Should have taken a screenshot: The link provided under Trivia returns no porn results whatsoever now (yes I have SafeSearch turned off). I'm pretty sure almost any search for a seldom used word or phrase returns a high number of porn results, but '''I seriously doubt''' any of the porn was actually ''about'' ometerometers, or even featured that word on the page. I think you just got unrelated results. I'm gonna have to say &amp;quot;citation needed&amp;quot; on that one, because the citation given yields no such results.

:: My laser power meter is pretty bad-assed - but the measurement tool I'm most impressed by isn't a &amp;quot;ometer&amp;quot;, it's a &amp;quot;mechanics level&amp;quot; - which is basically just an incredibly accurate spirit level - it can measure a tilt angle equal to the thickness of a single sheet of paper over a distance of two meters - which is pretty astounding considering how crude it is. You can tell that you have a cool -ometer if it comes in a nice wooden box - and a seriously cool one if the box has brass hinges and is lined with velvet...it's kindof a rule for us ometerometrists.

Let's all remember that there are some measurement devices that do not end in -ometer but rather simply in -meter, for example &amp;quot;multimeter&amp;quot;, &amp;quot;ohmmeter&amp;quot;, &amp;quot;ammeter&amp;quot;, etc. {{unsigned ip|108.162.221.77}}&lt;br /&gt;

I'm certainly not an expert on Google and how search results are generated, but I think it's at least highly likely that search results can be impacted by a user's previous searches and/or clicked results. While it might be interesting or even amusing, I don't think it's appropriate to include anything in the explanation of this comic about Rule 34 because it has absolutely nothing to do with the content of the comic itself!

&lt;div&gt;&lt;br /&gt;
{{comic&lt;br /&gt;

| titletext = How many points do you get for dunking every basketball in existence at once?&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
In this comic [[Cueball]] is repeatedly attempting to make a comparison for the {{w|Earth}}-{{w|Moon}} system; for an Earth the size of a {{w|Basketball (ball)|basketball}}, (24.6&amp;amp;nbsp;cm) the Moon would be 6.7&amp;amp;nbsp;cm, about the size of a some other smaller type of ball.[http://blogs.discovermagazine.com/badastronomy/2011/02/24/how-far-away-is-the-moon/] He handily illustrates this with two balls of those sizes that look like the Earth and the Moon. They are invisibly suspended, and—as seems clear from the first row of panels—they are actually the real Moon and Earth shrunk to the relevant size, hence the title ''Basketball Earth''. (This would place Cueball and his &amp;quot;friends&amp;quot; in {{w|God}}-like positions).&lt;br /&gt;
&lt;br /&gt;
But, repeatedly, before Cueball can finish with this common type of comparison, he is interrupted and must begin all over again. &lt;br /&gt;
&lt;br /&gt;
We never learn which type of ball (if any—it could have been an {{w|apple}}) he would have compared the Moon with. It is not unlikely that he would have mentioned a {{w|Baseball (ball)|baseball}}, but the comparison would be better using a {{w|tennis ball}}. A basketball has an average diameter of 24.6&amp;amp;nbsp;cm&amp;amp;nbsp;(9.7&amp;amp;nbsp;inches) vs.&amp;amp;nbsp;a tennis ball with an average diameter of 6.7&amp;amp;nbsp;cm&amp;amp;nbsp;(2.6&amp;amp;nbsp;inches).  The ratio between a tennis ball and basketball is 0.273, which is the same (to three digits) as the ratio given on the Wikipedia page for the Moon: ''Mean radius 1737.10&amp;amp;nbsp;km&amp;amp;nbsp;(0.273&amp;amp;nbsp;Earths)''. If he used the slightly larger baseball as an example, with an average diameter of 7.4&amp;amp;nbsp;cm&amp;amp;nbsp;(2.9&amp;amp;nbsp;inches), the ratio would be 0.300. Still this would be close enough for demonstrative purposes, as it would be with an apple.&lt;br /&gt;
&lt;br /&gt;
It is common to describe the relationship between very large (and very small) objects by analogy to common objects on a more human scale.  Here is a similar example where someone has made a comparison of the sizes of the Solar system based on a [http://www.backwoodshome.com/articles/silveira60.html Sun the size of a basketball]. And here, coming from smaller scales, is an [http://www.infoplease.com/dk/science/encyclopedia/atoms.html#ESCI024ATOMS001  example] that states the following: &amp;quot;Imagine an atom magnified to the size of a football stadium. The nucleus of the atom would be the size of a pea in the centre of the stadium.&amp;quot; &lt;br /&gt;
&lt;br /&gt;
It is almost certainly not a coincidence that today is {{w|Earth Day}}, which is celebrated annually on April&amp;amp;nbsp;22 to demonstrate support for environmental protection.  This seems to be something that [[Randall]] cares about a lot, as he has made several comics demonstrating the need for the human race to begin taking better care of our globe. See, for instance, [[1321: Cold]] and [[1379: 4.5 Degrees]].&lt;br /&gt;
&lt;br /&gt;
This comic clearly demonstrates four examples where the inhabitants of Earth did not take care of the well being of our globe, although here on a somewhat grander scale than what individuals can usually do. The typical case is that people did not do this out of bad intentions, but only because they were careless, curious, playful, or just plain stupid.&lt;br /&gt;
&lt;br /&gt;
===Interruptions===&lt;br /&gt;
The four interruptions are described below. Each of the four attempts has its own row of four panels in the comic. It is clear from panels one and two in each row that the Basketball Earth is rotating quite fast compared to the time frame of the comic since the {{w|continents}} have moved considerably between frames. It is thus not necessarily the interrupters that have moved the Basketball Earth between frames two and three, except of course in the final interruption. &lt;br /&gt;
&lt;br /&gt;
No matter how fast it rotates or whatever happens, we always see the Basketball Earth from the same side, as seen from far above the {{w|Atlantic Ocean}}. We can see the continents of the {{w|Americas}} as well as {{w|Africa}} and sometimes part of {{w|Europe}}, all of which are the borders for this ocean.&lt;br /&gt;
&lt;br /&gt;
It seems most likely that Cueball starts all over every time, with a completely fresh and new Earth-Moon system, since they look the same regardless of the catastrophe befalling the prior Basketball Earth, and the interruptions—the second especially—would be difficult to reverse. We can thus suppose that there is still &amp;quot;normal&amp;quot; life going on for each Basketball Earth before the interruption. This life will most likely completely perish for all of the last three cases.&lt;br /&gt;
&lt;br /&gt;
====Black Hat====&lt;br /&gt;
In the first interruption, [[Black Hat]] comes in and is amazed by this cool floating globe. Of course, being Black Hat, he has to prod this nice globe with a digit. But by putting his finger into one of the oceans of this &amp;quot;real&amp;quot; Basketball Earth without a second thought, he apparently generates a {{w|megatsunami}} that rolls in over an unidentified city with skyscrapers, utterly dwarfed by a breaking wave. &lt;br /&gt;
&lt;br /&gt;
This sequence might be a reference to a scene of &amp;quot;{{w|Men in Black II}}&amp;quot; where K messes with a globe that actually is a small planet, and his finger become visible in the sky of its inhabitants. It could also refer to {{w|Deep Impact (film)|Deep Impact}} in which a meteor strike causes exactly such a tsunami to hit the {{w|East Coast of the United States}}. Since Black Hat puts his finger down in the Atlantic Ocean, the tsunami would hit all bordering coastlines. And since the coast seems to be an eastern coast, and because Randall lives there, it is likely for the city to be {{w|New York City}} or {{w|Boston}} or one of the other large US cities on the East Coast. Of course, the wave would also affect the coast line (far into land) for all the other continents, but the author is from this part of the US East Coast.&lt;br /&gt;
&lt;br /&gt;
====Megan====&lt;br /&gt;
The second interruption occurs when [[Megan]] arrives and pours liquid (perhaps water) from a sports {{w|water bottle}} onto the Basketball Earth, seemingly flooding its entire surface.  This would make an {{w|List of flood myths|even worse tsunami}}, almost certainly extinguishing all land-dwelling life. The most famous somewhat analogous situation is from the {{w|Bible}} in the {{w|Genesis flood narrative}} about {{w|Noah's Ark}}. This time, however, the deluge is from the ocean, not rain, and the life in the sea may also perish due to the change in the constitution of the sea.&lt;br /&gt;
&amp;lt;!-- And water-life that got hit with salinity/temperature/pressure variations that it couldn't adapt to or avoid. --&amp;gt;&lt;br /&gt;
&amp;lt;!-- Also In my original edit-conflicted version, I mentioned the Waterworld movie, but maybe that's best forgotten. ;) --&amp;gt;&lt;br /&gt;
&amp;lt;!-- And I would have liked to have added wording about &amp;quot;local gravitational pull&amp;quot; acting as if a model... if that doesn't bring up larger questions about the tidal forces experienced upon Basketball Earth  by the proximity and movement of Cueball's head and rest of body, by such standards...--&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Cat====&lt;br /&gt;
In the third interruption a cat walks into shot and then playfully attacks the Basketball Earth rolling around with it like it would do with a ball of {{w|yarn}} (see real life example in [https://www.youtube.com/watch?v=k1rTAI2aExI this video]). &lt;br /&gt;
&lt;br /&gt;
The people living upon this Basketball Earth would experience cataclysmic events far greater than Blackhat's digital prodding incurred, especially as the Basketball Earth is no longer suspended and was thus taken &amp;quot;out of its orbit&amp;quot; and will eventually hit the floor very hard. One way or another, that will surely cause (undepicted) disasters of tremendous magnitude.&lt;br /&gt;
&lt;br /&gt;
====Ponytail====&lt;br /&gt;
In the fourth and final interruption, [[Ponytail]] uses Basketball Earth as an actual basketball. She comes running by Cueball, grabs the Basketball Earth, probably bouncing it off the floor while {{w|Dribbling#Basketball|dribbling}} towards the {{w|Backboard (basketball)|basketball hoop}} where she actually jumps in an attempt to {{w|Slam dunk|dunk}} the Basketball Earth.  This would ''not'' be good for any residents of Basketball Earth; the combined pressure, movement, and impact damage from this simple sequence would surely kill off all life on Basketball Earth.&lt;br /&gt;
&lt;br /&gt;
====Title text====&lt;br /&gt;
This simile-callback is continued in the title text with the idea that &amp;quot;every basketball in existence&amp;quot; (i.e., every basketball upon the Basketball Earth, as well as the Basketball Earth itself) is counted towards the score from a single dunking.  &lt;br /&gt;
&lt;br /&gt;
Randall may or may not know exactly how many basketballs there are, perhaps through research for some [[what if?]] question or other research, but almost certainly assumes that there are no extraterrestrial basketballs ''not'' on Basketball Earth.  But there might be some question about whether the Basketball Earth's own sub-scale basketballs fall within the regulations.&lt;br /&gt;
&amp;lt;!-- Had originally considered referencing a pun like &amp;quot;Search for Extra-Terrestrial Basketball&amp;quot;, c.f. SETI, but this is surely already getting too long and boring an explanation... --&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is standing next to a floating Basketball Earth indicating it with his left hand. The continents are clearly visible as seen from above the Atlantic Ocean. This remains the same all through the comic, except that the Basketball Earth rotates a bit from frame to frame.]&lt;br /&gt;
:Cueball: If the Earth were the size of a basketball,&lt;br /&gt;
&lt;br /&gt;
:[Cueball is now indicating, with his right hand, a small pockmarked moon (also floating), in the correct proportions (size and distance) to the Basketball Earth, which is on his other side. Black Hat walks into the panel towards Earth.]&lt;br /&gt;
:Cueball: The Moon would be—&lt;br /&gt;
:Black Hat: Hey, cool!&lt;br /&gt;
&lt;br /&gt;
:[Black Hat is touching the Basketball Earth with a digit.]&lt;br /&gt;
:Cueball: Um.&lt;br /&gt;
&lt;br /&gt;
:[In the next scene we see a megatsunami on the verge of crashing down onto a coastal city with skyscrapers. The A's are cut of on each side of the panels frames, i.e. they begin outside and finishes outside the frame.]&lt;br /&gt;
:Aaaaaaaa&lt;br /&gt;
&lt;br /&gt;
:[Back to Cueball standing with the Basketball Earth in the same position as the first panel.]&lt;br /&gt;
:Cueball: Let's try that again. If the Earth were the size of a basketball,&lt;br /&gt;
&lt;br /&gt;
:[Same situation as when Black Hat walked in, except now it is Megan that walks into the frame towards the Basketball Earth holding a sports water bottle.]&lt;br /&gt;
:Cueball: The Moon would be—&lt;br /&gt;
&lt;br /&gt;
:[Megan squirts the Basketball Earth with the liquid in her water bottle while Cueball just stands watching with the Moon behind him].&lt;br /&gt;
&lt;br /&gt;
:[Megan just walks away while Cueball stares at his &amp;quot;water&amp;quot; Basketball Earth where the continents have disappeared completely beneath the liquid.]&lt;br /&gt;
&lt;br /&gt;
:[Back to Cueball standing with the Basketball Earth in the same position as the first panel.]&lt;br /&gt;
:Cueball: If the Earth were the size of a basketball,&lt;br /&gt;
&lt;br /&gt;
:[Same situation as when Black Hat walked in, except now he spots a cat coming into the frame from the left.]&lt;br /&gt;
:Cueball: The Moon— would…&lt;br /&gt;
&lt;br /&gt;
:[While Cueball watches with the Moon behind him, the cat jumps at the Basketball Earth.]&lt;br /&gt;
:Cat: Mrowl! &lt;br /&gt;
&lt;br /&gt;
:[Cueball continues to watch while the cat rolls around playing with the Basketball Earth as if it was a ball of yarn.]&lt;br /&gt;
:Cat: Rrrrr&lt;br /&gt;
&lt;br /&gt;
:[Back to Cueball standing with the Basketball Earth in the same position as the first panel.]&lt;br /&gt;
:Cueball: If the Earth were the size of a basketball,&lt;br /&gt;
&lt;br /&gt;
:[Same situation as when Black Hat walked in, except this time it is Ponytail who enters the frame at a run coming from the left.]&lt;br /&gt;
:Cueball: The Moon would, uh…&lt;br /&gt;
&lt;br /&gt;
:[While Cueball watches with the Moon behind him, Ponytail has grabbed the Basketball Earth and is dribbling it out of the frame, still running.]&lt;br /&gt;
&lt;br /&gt;
:[Zoom out from Cueball who continues to watch while Ponytail reaches a basketball hoop and jump towards it with the Basketball Earth, obviously in an attempt to make a slam dunk.]&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
In this comic [[Cueball]] is repeatedly attempting to make a comparison for the {{w|Earth}}-{{w|Moon}} system; for an Earth the size of a {{w|Basketball (ball)|basketball}}, (24.6&amp;amp;nbsp;cm) the Moon would be 6.7&amp;amp;nbsp;cm, about the size of a some other smaller type of ball.[http://blogs.discovermagazine.com/badastronomy/2011/02/24/how-far-away-is-the-moon/] He handily illustrates this with two balls of those sizes that look like the Earth and the Moon. They are invisibly suspended, and—as seems clear from the first row of panels—they are actually the real Moon and Earth shrunk to the relevant size, hence the title ''Basketball Earth''. (This would place Cueball and his &amp;quot;friends&amp;quot; in {{w|God}}-like positions).&lt;br /&gt;
&lt;br /&gt;
But, repeatedly, before Cueball can finish with this common type of comparison, he is interrupted and must begin all over again. &lt;br /&gt;
&lt;br /&gt;
We never learn which type of ball (if any—it could have been an {{w|apple}}) he would have compared the Moon with. It is not unlikely that he would have mentioned a {{w|Baseball (ball)|baseball}}, but the comparison would be better using a {{w|tennis ball}}. A basketball has an average diameter of 24.6&amp;amp;nbsp;cm&amp;amp;nbsp;(9.7&amp;amp;nbsp;inches) vs.&amp;amp;nbsp;a tennis ball with an average diameter of 6.7&amp;amp;nbsp;cm&amp;amp;nbsp;(2.6&amp;amp;nbsp;inches).  The ratio between a tennis ball and basketball is 0.273, which is the same (to three digits) as the ratio given on the Wikipedia page for the Moon: ''Mean radius 1737.10&amp;amp;nbsp;km&amp;amp;nbsp;(0.273&amp;amp;nbsp;Earths)''. If he used the slightly larger baseball as an example, with an average diameter of 7.4&amp;amp;nbsp;cm&amp;amp;nbsp;(2.9&amp;amp;nbsp;inches), the ratio would be 0.300. Still this would be close enough for demonstrative purposes, as it would be with an apple.&lt;br /&gt;
&lt;br /&gt;
It is common to describe the relationship between very large (and very small) objects by analogy to common objects on a more human scale.  Here is a similar example where someone has made a comparison of the sizes of the Solar system based on a [http://www.backwoodshome.com/articles/silveira60.html Sun the size of a basketball]. And here, coming from smaller scales, is an [http://www.infoplease.com/dk/science/encyclopedia/atoms.html#ESCI024ATOMS001  example] that states the following: &amp;quot;Imagine an atom magnified to the size of a football stadium. The nucleus of the atom would be the size of a pea in the centre of the stadium.&amp;quot; &lt;br /&gt;
&lt;br /&gt;
It is almost certainly not a coincidence that today is {{w|Earth Day}}, which is celebrated annually on April&amp;amp;nbsp;22 to demonstrate support for environmental protection.  This seems to be something that [[Randall]] cares about a lot, as he has made several comics demonstrating the need for the human race to begin taking better care of our globe. See, for instance, [[1321: Cold]] and [[1379: 4.5 Degrees]].&lt;br /&gt;
&lt;br /&gt;
This comic clearly demonstrates four examples where the inhabitants of Earth did not take care of the well being of our globe, although here on a somewhat grander scale than what individuals can usually do. The typical case is that people did not do this out of bad intentions, but only because they were careless, curious, playful, or just plain stupid.&lt;br /&gt;
&lt;br /&gt;
===Interruptions===&lt;br /&gt;
The four interruptions are described below. Each of the four attempts has its own row of four panels in the comic. It is clear from panels one and two in each row that the Basketball Earth is rotating quite fast compared to the time frame of the comic since the {{w|continents}} have moved considerably between frames. It is thus not necessarily the interrupters that have moved the Basketball Earth between frames two and three, except of course in the final interruption. &lt;br /&gt;
&lt;br /&gt;
No matter how fast it rotates or whatever happens, we always see the Basketball Earth from the same side, as seen from far above the {{w|Atlantic Ocean}}. We can see the continents of the {{w|Americas}} as well as {{w|Africa}} and sometimes part of {{w|Europe}}, all of which are the borders for this ocean.&lt;br /&gt;
&lt;br /&gt;
It seems most likely that Cueball starts all over every time, with a completely fresh and new Earth-Moon system, since they look the same regardless of the catastrophe befalling the prior Basketball Earth, and the interruptions—the second especially—would be difficult to reverse. We can thus suppose that there is still &amp;quot;normal&amp;quot; life going on for each Basketball Earth before the interruption. This life will most likely completely perish for all of the last three cases.&lt;br /&gt;
&lt;br /&gt;
====Black Hat====&lt;br /&gt;
In the first interruption, [[Black Hat]] comes in and is amazed by this cool floating globe. Of course, being Black Hat, he has to prod this nice globe with a digit. But by putting his finger into one of the oceans of this &amp;quot;real&amp;quot; Basketball Earth without a second thought, he apparently generates a {{w|megatsunami}} that rolls in over an unidentified city with skyscrapers, utterly dwarfed by a breaking wave. &lt;br /&gt;
&lt;br /&gt;
This sequence might be a reference to a scene of &amp;quot;{{w|Men in Black II}}&amp;quot; where K messes with a globe that actually is a small planet, and his finger become visible in the sky of its inhabitants. It could also refer to {{w|Deep Impact (film)|Deep Impact}} in which a meteor strike causes exactly such a tsunami to hit the {{w|East Coast of the United States}}. Since Black Hat puts his finger down in the Atlantic Ocean, the tsunami would hit all bordering coastlines. And since the coast seems to be an eastern coast, and because Randall lives there, it is likely for the city to be {{w|New York City}} or {{w|Boston}} or one of the other large US cities on the East Coast. Of course, the wave would also affect the coast line (far into land) for all the other continents, but the author is from this part of the US East Coast.&lt;br /&gt;
&lt;br /&gt;
====Megan====&lt;br /&gt;
The second interruption occurs when [[Megan]] arrives and pours liquid (perhaps water) from a sports {{w|water bottle}} onto the Basketball Earth, seemingly flooding its entire surface.  This would make an {{w|List of flood myths|even worse tsunami}}, almost certainly extinguishing all land-dwelling life. Such a situation is most famously known from the {{w|Bible}} in the {{w|Genesis flood narrative}} about {{w|Noah's Ark}}. Of course this time the life in the sea may also perish due to the change in the constitution of the sea.&lt;br /&gt;
&amp;lt;!-- And water-life that got hit with salinity/temperature/pressure variations that it couldn't adapt to or avoid. --&amp;gt;&lt;br /&gt;
&amp;lt;!-- Also In my original edit-conflicted version, I mentioned the Waterworld movie, but maybe that's best forgotten. ;) --&amp;gt;&lt;br /&gt;
&amp;lt;!-- And I would have liked to have added wording about &amp;quot;local gravitational pull&amp;quot; acting as if a model... if that doesn't bring up larger questions about the tidal forces experienced upon Basketball Earth  by the proximity and movement of Cueball's head and rest of body, by such standards...--&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Cat====&lt;br /&gt;
In the third interruption a cat walks into shot and then playfully attacks the Basketball Earth rolling around with it like it would do with a ball of {{w|yarn}} (see real life example in [https://www.youtube.com/watch?v=k1rTAI2aExI this video]). &lt;br /&gt;
&lt;br /&gt;
The people living upon this Basketball Earth would experience cataclysmic events far greater than Blackhat's digital prodding incurred, especially as the Basketball Earth is no longer suspended and was thus taken &amp;quot;out of its orbit&amp;quot; and will eventually hit the floor very hard. One way or another, that will surely cause (undepicted) disasters of tremendous magnitude.&lt;br /&gt;
&lt;br /&gt;
====Ponytail====&lt;br /&gt;
In the fourth and final interruption, [[Ponytail]] uses Basketball Earth as an actual basketball. She comes running by Cueball, grabs the Basketball Earth, probably bouncing it off the floor while {{w|Dribbling#Basketball|dribbling}} towards the {{w|Backboard (basketball)|basketball hoop}} where she actually jumps in an attempt to {{w|Slam dunk|dunk}} the Basketball Earth.  This would ''not'' be good for any residents of Basketball Earth; the combined pressure, movement, and impact damage from this simple sequence would surely kill off all life on Basketball Earth.&lt;br /&gt;
&lt;br /&gt;
====Title text====&lt;br /&gt;
This simile-callback is continued in the title text with the idea that &amp;quot;every basketball in existence&amp;quot; (i.e., every basketball upon the Basketball Earth, as well as the Basketball Earth itself) is counted towards the score from a single dunking.  &lt;br /&gt;
&lt;br /&gt;
Randall may or may not know exactly how many basketballs there are, perhaps through research for some [[what if?]] question or other research, but almost certainly assumes that there are no extraterrestrial basketballs ''not'' on Basketball Earth.  But there might be some question about whether the Basketball Earth's own sub-scale basketballs fall within the regulations.&lt;br /&gt;
&amp;lt;!-- Had originally considered referencing a pun like &amp;quot;Search for Extra-Terrestrial Basketball&amp;quot;, c.f. SETI, but this is surely already getting too long and boring an explanation... --&amp;gt;&lt;br /&gt;

They are invisibly suspended, and—as seems clear from the first row of panels—they are actually the real Moon and Earth shrunk to the relevant size, hence the title ''Basketball Earth''. (This would place Cueball and his &amp;quot;friends&amp;quot; in {{w|God}}-like positions).&lt;br /&gt;
&lt;br /&gt;
But, repeatedly, before Cueball can finish with this common type of comparison, he is interrupted and must begin all over again. &lt;br /&gt;
&lt;br /&gt;
We never learn which type of ball (if any—it could have been an {{w|apple}}) he would have compared the Moon with. It is not unlikely that he would have mentioned a {{w|Baseball (ball)|baseball}}, but the comparison would be better using a {{w|tennis ball}}. A basketball has an average diameter of 24.6&amp;amp;nbsp;cm&amp;amp;nbsp;(9.7&amp;amp;nbsp;inches) vs.&amp;amp;nbsp;a tennis ball with an average diameter of 6.7&amp;amp;nbsp;cm&amp;amp;nbsp;(2.6&amp;amp;nbsp;inches).  The ratio between a tennis ball and basketball is 0.273, which is the same (to three digits) as the ratio given on the Wikipedia page for the Moon: ''Mean radius 1737.10&amp;amp;nbsp;km&amp;amp;nbsp;(0.273&amp;amp;nbsp;Earths)''. If he used the slightly larger baseball as an example, with an average diameter of 7.4&amp;amp;nbsp;cm&amp;amp;nbsp;(2.9&amp;amp;nbsp;inches), the ratio would be 0.300. Still this would be close enough for demonstrative purposes, as it would be with an apple.&lt;br /&gt;
&lt;br /&gt;
It is common to describe the relationship between very large (and very small) objects by analogy to common objects on a more human scale.  Here is a similar example where someone has made a comparison of the sizes of the Solar system based on a [http://www.backwoodshome.com/articles/silveira60.html Sun the size of a basketball]. And here, coming from smaller scales, is an [http://www.infoplease.com/dk/science/encyclopedia/atoms.html#ESCI024ATOMS001  example] that states the following: &amp;quot;Imagine an atom magnified to the size of a football stadium. The nucleus of the atom would be the size of a pea in the centre of the stadium.&amp;quot; &lt;br /&gt;
&lt;br /&gt;
It is almost certainly not a coincidence that today is {{w|Earth Day}}, which is celebrated annually on April&amp;amp;nbsp;22 to demonstrate support for environmental protection.

&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
In this comic [[Cueball]] is repeatedly attempting to make a comparison for the {{w|Earth}}-{{w|Moon}} system; for an Earth the size of a {{w|Basketball (ball)|basketball}}, (24.6&amp;amp;nbsp;cm) the Moon would be 6.7&amp;amp;nbsp;cm, about the size of a some other smaller type of ball.[http://blogs.discovermagazine.com/badastronomy/2011/02/24/how-far-away-is-the-moon/] He handily illustrates this with two balls of those sizes that look like the Earth and the Moon. They are invisibly suspended, and—as seems clear from the first row of panels—they are actually the real Moon and Earth shrunk to the relevant size, hence the title ''Basketball Earth''. (This would place Cueball and his &amp;quot;friends&amp;quot; in {{w|God}}-like positions).&lt;br /&gt;
&lt;br /&gt;
But, repeatedly, before Cueball can finish with this common type of comparison, he is interrupted and must begin all over again. &lt;br /&gt;
&lt;br /&gt;
We never learn which type of ball (if any—it could have been an {{w|apple}}) he would have compared the Moon with. It is not unlikely that he would have mentioned a {{w|Baseball (ball)|baseball}}, but the comparison would be better using a {{w|tennis ball}}. A basketball has an average diameter of 24.6&amp;amp;nbsp;cm&amp;amp;nbsp;(9.7&amp;amp;nbsp;inches) vs.&amp;amp;nbsp;a tennis ball with an average diameter of 6.7&amp;amp;nbsp;cm&amp;amp;nbsp;(2.6&amp;amp;nbsp;inches).  The ratio between a tennis ball and basketball is 0.273, which is the same (to three digits) as the ratio given on the Wikipedia page for the Moon: ''Mean radius 1737.10&amp;amp;nbsp;km&amp;amp;nbsp;(0.273nbsp;Earths)''. If he used the slightly larger baseball as an example, with an average diameter of 7.4&amp;amp;nbsp;cm&amp;amp;nbsp;(2.9&amp;amp;nbsp;inches), the ratio would be 0.300. Still this would be close enough for demonstrative purposes, as it would be with an apple.&lt;br /&gt;
&lt;br /&gt;
It is common to describe the relationship between very large (and very small) objects by analogy to common objects on a more human scale.  Here is a similar example where someone has made a comparison of the sizes of the Solar system based on a [http://www.backwoodshome.com/articles/silveira60.html Sun the size of a basketball]. And here, coming from smaller scales, is an [http://www.infoplease.com/dk/science/encyclopedia/atoms.html#ESCI024ATOMS001  example] that states the following: &amp;quot;Imagine an atom magnified to the size of a football stadium. The nucleus of the atom would be the size of a pea in the centre of the stadium.&amp;quot; &lt;br /&gt;
&lt;br /&gt;
It is almost certainly not a coincidence that today is {{w|Earth Day}}, which is celebrated annually on April&amp;amp;nbsp;22 to demonstrate support for environmental protection.  This seems to be something that [[Randall]] cares about a lot, as he has made several comics demonstrating the need for the human race to begin taking better care of our globe. See, for instance, [[1321: Cold]] and [[1379: 4.5 Degrees]].&lt;br /&gt;
&lt;br /&gt;
This comic clearly demonstrates four examples where the inhabitants of Earth did not take care of the well being of our globe, although here on a somewhat grander scale than what individuals can usually do. The typical case is that people did not do this out of bad intentions, but only because they were careless, curious, playful, or just plain stupid.&lt;br /&gt;
&lt;br /&gt;
===Interruptions===&lt;br /&gt;
The four interruptions are described below. Each of the four attempts has its own row of four panels in the comic. It is clear from panels one and two in each row that the Basketball Earth is rotating quite fast compared to the time frame of the comic since the {{w|continents}} have moved considerably between frames. It is thus not necessarily the interrupters that have moved the Basketball Earth between frames two and three, except of course in the final interruption. &lt;br /&gt;
&lt;br /&gt;
No matter how fast it rotates or whatever happens, we always see the Basketball Earth from the same side, as seen from far above the {{w|Atlantic Ocean}}. We can see the continents of the {{w|Americas}} as well as {{w|Africa}} and sometimes part of {{w|Europe}}, all of which are the borders for this ocean.&lt;br /&gt;
&lt;br /&gt;
It seems most likely that Cueball starts all over every time, with a completely fresh and new Earth-Moon system, since they look the same regardless of the catastrophe befalling the prior Basketball Earth, and the interruptions—the second especially—would be difficult to reverse. We can thus suppose that there is still &amp;quot;normal&amp;quot; life going on for each Basketball Earth before the interruption. This life will most likely completely perish for all of the last three cases.&lt;br /&gt;
&lt;br /&gt;
====Black Hat====&lt;br /&gt;
In the first interruption, [[Black Hat]] comes in and is amazed by this cool floating globe. Of course, being Black Hat, he has to prod this nice globe with a digit. But by putting his finger into one of the oceans of this &amp;quot;real&amp;quot; Basketball Earth without a second thought, he apparently generates a {{w|megatsunami}} that rolls in over an unidentified city with skyscrapers, utterly dwarfed by a breaking wave. &lt;br /&gt;
&lt;br /&gt;
It might be a reference to a scene of &amp;quot;{{w|Men in Black II}}&amp;quot; where K messes with a globe that actually is a small planet, and his finger become visible in the sky of its inhabitants. It could also refer to {{w|Deep Impact (film)|Deep Impact}} in which a meteor strike causes exactly such a tsunami to hit the {{w|East Coast of the United States}}. Since Black Hat puts his finger down in the Atlantic Ocean, the tsunami would hit all bordering coastlines. And since the coast seems to be an eastern coast, and because Randall lives there, it is likely for the city to be {{w|New York City}} or {{w|Boston}} or one of the other large US cities on the East Coast. Of course the wave would also affect the coast line (far into land) for all the other continents, but the author is from this part of the US East Coast.&lt;br /&gt;
&lt;br /&gt;
====Megan====&lt;br /&gt;
The second interruption occurs when [[Megan]] arrives and pours liquid (perhaps water) from a sports {{w|water bottle}} onto the Basketball Earth, seemingly flooding its entire surface.  This would make an {{w|List of flood myths|even worse tsunami}}, almost certainly extinguishing all land-dwelling life. Such a situation is most famously known from the {{w|Bible}} in the {{w|Genesis flood narrative}} about {{w|Noah's Ark}}. Of course this time the life in the sea may also perish due to the change in the constitution of the sea.&lt;br /&gt;
&amp;lt;!-- And water-life that got hit with salinity/temperature/pressure variations that it couldn't adapt to or avoid. --&amp;gt;&lt;br /&gt;
&amp;lt;!-- Also In my original edit-conflicted version, I mentioned the Waterworld movie, but maybe that's best forgotten. ;) --&amp;gt;&lt;br /&gt;
&amp;lt;!-- And I would have liked to have added wording about &amp;quot;local gravitational pull&amp;quot; acting as if a model... if that doesn't bring up larger questions about the tidal forces experienced upon Basketball Earth  by the proximity and movement of Cueball's head and rest of body, by such standards...--&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Cat====&lt;br /&gt;
In the third interruption a cat walks into shot and then playfully attacks the Basketball Earth rolling around with it like it would do with a ball of {{w|yarn}} (see real life example in [https://www.youtube.com/watch?v=k1rTAI2aExI this video]). &lt;br /&gt;
&lt;br /&gt;
The people living upon this Basketball Earth would experience cataclysmic events far greater than Blackhat's digital prodding incurred, especially as the Basketball Earth is no longer suspended and was thus taken &amp;quot;out of its orbit&amp;quot; and will eventually hit the floor very hard. One way or another, that will surely cause (undepicted) disasters of tremendous magnitude.&lt;br /&gt;
&lt;br /&gt;
====Ponytail====&lt;br /&gt;
In the fourth and final interruption, [[Ponytail]] uses Basketball Earth as an actual basketball. She comes running by Cueball, grabs the Basketball Earth, probably bouncing it off the floor while {{w|Dribbling#Basketball|dribbling}} towards the {{w|Backboard (basketball)|basketball hoop}} where she actually jumps in an attempt to {{w|Slam dunk|dunk}} the Basketball Earth.  This would ''not'' be good for any residents of Basketball Earth; the combined pressure, movement, and impact damage from this simple sequence would surely kill off all life on Basketball Earth.&lt;br /&gt;
&lt;br /&gt;
====Title text====&lt;br /&gt;
This simile-callback is continued in the title text with the idea that &amp;quot;every basketball in existence&amp;quot; (i.e., every basketball upon the Basketball Earth, as well as the Basketball Earth itself) is counted towards the score from a single dunking.  &lt;br /&gt;
&lt;br /&gt;
Randall may or may not know exactly how many basketballs there are, perhaps through research for some [[what if?]] question or other research, but almost certainly assumes that there are no extraterrestrial basketballs ''not'' on Basketball Earth.  But there might be some question about whether the Basketball Earth's own sub-scale basketballs fall within the regulations.&lt;br /&gt;
&amp;lt;!-- Had originally considered referencing a pun like &amp;quot;Search for Extra-Terrestrial Basketball&amp;quot;, c.f. SETI, but this is surely already getting too long and boring an explanation... --&amp;gt;&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
In this comic [[Cueball]] is repeatedly attempting to make a comparison for the {{w|Earth}}-{{w|Moon}} system; for an Earth the size of a {{w|Basketball (ball)|basketball}}, (24.6&amp;amp;nbsp;cm) the Moon would be 6.7&amp;amp;nbsp;cm, about the size of a some other smaller type of ball.[http://blogs.discovermagazine.com/badastronomy/2011/02/24/how-far-away-is-the-moon/] He handily illustrates this with two balls of those sizes that look like the Earth and the Moon. They are invisibly suspended, and—as seems clear from the first row of panels—they are actually the real Moon and Earth shrunk to the relevant size, hence the title ''Basketball Earth''. (This would place Cueball and his &amp;quot;friends&amp;quot; in {{w|God}}-like positions).&lt;br /&gt;
&lt;br /&gt;
But, repeatedly, before Cueball can finish with this common type of comparison, he is interrupted and must begin all over again. &lt;br /&gt;
&lt;br /&gt;
We never learn which type of ball (if any—it could have been an {{w|apple}}) he would have compared the Moon with. It is not unlikely that he would have mentioned a {{w|Baseball (ball)|baseball}}, but the comparison would be better using a {{w|tennis ball}}. A basketball has an average diameter of 24.6&amp;amp;nbsp;cm&amp;amp;nbs(9.7&amp;amp;nbsp;inches) vs.&amp;amp;nbsp;a tennis ball with an average diameter of 6.7&amp;amp;nbsp;cm&amp;amp;nbsp;(2.6&amp;amp;nbsp;inches).  The ratio between a tennis ball and basketball is 0.273, which is the same (to three digits) as the ratio given on the Wikipedia page for the Moon: ''Mean radius 1737.10&amp;amp;nbsp;km&amp;amp;nbsp;(0.273nbsp;Earths)''. If he used the slightly larger baseball as an example, with an average diameter of 7.4&amp;amp;nbsp;cm&amp;amp;nbsp;(2.9&amp;amp;nbsp;inches), the ratio would be 0.300. Still this would be close enough for demonstrative purposes, as it would be with an apple.&lt;br /&gt;
&lt;br /&gt;
It is common to describe the relationship between very large (and very small) objects by analogy to common objects on a more human scale.  Here is a similar example where someone has made a comparison of the sizes of the Solar system based on a [http://www.backwoodshome.com/articles/silveira60.html Sun the size of a basketball]. And here, coming from smaller scales, is an [http://www.infoplease.com/dk/science/encyclopedia/atoms.html#ESCI024ATOMS001  example] that states the following: &amp;quot;Imagine an atom magnified to the size of a football stadium. The nucleus of the atom would be the size of a pea in the centre of the stadium.&amp;quot; &lt;br /&gt;
&lt;br /&gt;
It is almost certainly not a coincidence that today is {{w|Earth Day}}, which is celebrated annually on April&amp;amp;nbsp;22 to demonstrate support for environmental protection.  This seems to be something that [[Randall]] cares about a lot, as he has made several comics demonstrating the need for the human race to begin taking better care of our globe. See, for instance, [[1321: Cold]] and [[1379: 4.5 Degrees]].&lt;br /&gt;
&lt;br /&gt;
This comic clearly demonstrates four examples where the inhabitants of Earth did not take care of the well being of our globe, although here on a somewhat grander scale than what individuals can usually do. The typical case is that people did not do this out of bad intentions, but only because they were careless, curious, playful, or just plain stupid.&lt;br /&gt;
&lt;br /&gt;
===Interruptions===&lt;br /&gt;
The four interruptions are described below. Each of the four attempts has its own row of four panels in the comic. It is clear from panels one and two in each row that the Basketball Earth is rotating quite fast compared to the time frame of the comic since the {{w|continents}} have moved considerably between frames. It is thus not necessarily the interrupters that have moved the Basketball Earth between frames two and three, except of course in the final interruption. &lt;br /&gt;
&lt;br /&gt;
No matter how fast it rotates or whatever happens, we always see the Basketball Earth from the same side, as seen from far above the {{w|Atlantic Ocean}}. We can see the continents of the {{w|Americas}} as well as {{w|Africa}} and sometimes part of {{w|Europe}}, all of which are the borders for this ocean.&lt;br /&gt;
&lt;br /&gt;
It seems most likely that Cueball starts all over every time, with a completely fresh and new Earth-Moon system, since they look the same regardless of the catastrophe befalling the prior Basketball Earth, and the interruptions—the second especially—would be difficult to reverse. We can thus suppose that there is still &amp;quot;normal&amp;quot; life going on for each Basketball Earth before the interruption. This life will most likely completely perish for all of the last three cases.&lt;br /&gt;
&lt;br /&gt;
====Black Hat====&lt;br /&gt;
In the first interruption, [[Black Hat]] comes in and is amazed by this cool floating globe. Of course, being Black Hat, he has to prod this nice globe with a digit. But by putting his finger into one of the oceans of this &amp;quot;real&amp;quot; Basketball Earth without a second thought, he apparently generates a {{w|megatsunami}} that rolls in over an unidentified city with skyscrapers, utterly dwarfed by a breaking wave. &lt;br /&gt;
&lt;br /&gt;
It might be a reference to a scene of &amp;quot;{{w|Men in Black II}}&amp;quot; where K messes with a globe that actually is a small planet, and his finger become visible in the sky of its inhabitants. It could also refer to {{w|Deep Impact (film)|Deep Impact}} in which a meteor strike causes exactly such a tsunami to hit the {{w|East Coast of the United States}}. Since Black Hat puts his finger down in the Atlantic Ocean, the tsunami would hit all bordering coastlines. And since the coast seems to be an eastern coast, and because Randall lives there, it is likely for the city to be {{w|New York City}} or {{w|Boston}} or one of the other large US cities on the East Coast. Of course the wave would also affect the coast line (far into land) for all the other continents, but the author is from this part of the US East Coast.&lt;br /&gt;
&lt;br /&gt;
====Megan====&lt;br /&gt;
The second interruption occurs when [[Megan]] arrives and pours liquid (perhaps water) from a sports {{w|water bottle}} onto the Basketball Earth, seemingly flooding its entire surface.  This would make an {{w|List of flood myths|even worse tsunami}}, almost certainly extinguishing all land-dwelling life. Such a situation is most famously known from the {{w|Bible}} in the {{w|Genesis flood narrative}} about {{w|Noah's Ark}}. Of course this time the life in the sea may also perish due to the change in the constitution of the sea.&lt;br /&gt;
&amp;lt;!-- And water-life that got hit with salinity/temperature/pressure variations that it couldn't adapt to or avoid. --&amp;gt;&lt;br /&gt;
&amp;lt;!-- Also In my original edit-conflicted version, I mentioned the Waterworld movie, but maybe that's best forgotten. ;) --&amp;gt;&lt;br /&gt;
&amp;lt;!-- And I would have liked to have added wording about &amp;quot;local gravitational pull&amp;quot; acting as if a model... if that doesn't bring up larger questions about the tidal forces experienced upon Basketball Earth  by the proximity and movement of Cueball's head and rest of body, by such standards...--&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Cat====&lt;br /&gt;
In the third interruption, a cat walks into shot and then playfully attacks the Basketball Earth rolling around with it like it would do with a ball of {{w|yarn}} (see real life example in [https://www.youtube.com/watch?v=k1rTAI2aExI this video]). &lt;br /&gt;
&lt;br /&gt;
The people living upon the Basketball Earth would experience cataclismic events far greater than Blackhat's digital prodding incurred, especially as the Basketball Earth is no longer suspended and was thus taken 'out of its  orbit' and will eventually hit the floor very hard. One way or another, that will have surely cause (undepicted) disasters of cataclismic proportions compared what by Black Hat managed during the first time interruption.&lt;br /&gt;
&amp;lt;!-- Has it quite hit the floor yet? That's gonna hurt, if/when it does. --&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Ponytail====&lt;br /&gt;
In the fourth and final interruption [[Ponytail]] uses Basketball Earth as an actual basketball. She comes running by Cueball, grabs the Basketball Earth, probably bouncing it off the floor while {{w|Dribbling#Basketball|dribbling}} towards the {{w|Backboard (basketball)|basketball hoop}} where she actually jumps in an attempt to {{w|Slam dunk|dunk}} the Basketball Earth.  This would ''not'' be good for any residents of Basketball Earth, with the combined pressure, movement and impact damage this simple sequence would surely kill off all life on Basketball Earth, maybe even destroying it completely when it hits the ground from the Slam Dunk.&lt;br /&gt;
&lt;br /&gt;
====Title text====&lt;br /&gt;
This simile-callback is continued in the title text with the idea that &amp;quot;every basketball in existence&amp;quot; (i.e. every basketball upon the Basketball Earth, as well as the Basketball Earth itself) is counted towards the score from a single dunking.  &lt;br /&gt;
&lt;br /&gt;
Randall may or may not know exactly how many basketballs there are, perhaps through research for some [[what if?]] question or other research, but almost certainly assumes that there are no basketballs ''not'' on Basketball Earth, as well we might ourselves regarding the existence of extra-terrestrial basketballs, even without allowing for recursion.  But there might be some question about whether the Basketball Earths own sub-scale basketballs fall within the regulations.&lt;br /&gt;
&amp;lt;!-- Had originally considered referencing a pun like &amp;quot;Search for Extra-Terrestrial Basketball&amp;quot;, c.f. SETI, but this is surely already getting too long and boring an explanation... --&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;

In this comic [[Cueball]] is repeatedly attempting to make the comparison that for the {{w|Earth}}-{{w|Moon}} system, the Moon would be about the size of a {{w|baseball}} for an Earth the size of a {{w|basketball}}. &lt;br /&gt;
&lt;br /&gt;
He handily illustrates this with two balls of those sizes that looks like the Earth and the Moon. They are invisibly suspended, or as seems clear from the first row of panels, are actually the real ones shrunk to the relevant size. But before he can finish with this common type of comparison he is being repeatedly interrupted and must begin all over again. Maybe he even have to start with a new Earth-Moon system, since they look the same every time independent of the catastrophe occurring to Earth each time. Each of the four attempt has it's own row of four panels in the comic.&lt;br /&gt;
&lt;br /&gt;
Here is a similar example where someone has made a comparison of the sizes of the Soalr system based on a [http://www.backwoodshome.com/articles/silveira60.html Sun the size of a Basketball]. &lt;br /&gt;
&lt;br /&gt;
It is common to describe the relationship of very large (and very small) objects to common objects on a more human scale. In the other end for small items, it might be something along the lines of if a certain single atom were expanded to a visible size then for a particular sports stadium the electrons cloud would be on the perimeter of the complex. In this case the nucleus would still be something surprisingly small, by human standards, located upon the central-spot.&lt;br /&gt;
&lt;br /&gt;
In the first interruption, [[Black Hat]] comes in and is amazed by this cool floating globe. Of course, being Black Hat, he has to make a digital prodding of this nice globe. But by putting his finger into one of the oceans of this &amp;quot;real&amp;quot; Earth, without a second thought, he thus generates a {{w|megatsunami}} of epic proportions, that rolls in over a large city, dwarfed at the foot of the wave.&lt;br /&gt;
&lt;br /&gt;
In the second interruption, [[Megan]] comes in and pours water from a half-liter bottle onto the Earthball, seemingly flooding its entire surface. This would make an {{w|List of flood myths|even worse tsunami}}, almost certainly extinguishing all land-dwelling life.&lt;br /&gt;
&lt;br /&gt;
In the third interruption, a cat enters and playfully attacks the 'Earth'. But it will result in forces far greater than those exerted by Black Hat's digital prodding, and may have even taken the Earth out of its (representative) orbit.  One way or another, that will have resulted in (for us unseen) disasters of far greater proportion.&lt;br /&gt;
&lt;br /&gt;
The fourth interruption involves [[Ponytail]] taking the 'basketball' comparison at face value and actually trying to dunk the 'Earth' ''as'' a basketball.  This would ''not'' be good for any residents of Earthball who have yet to succumb to the events so far.  This simile-callback is continued in the title text with the idea that &amp;quot;every basketball in existence&amp;quot; (i.e. every basketball upon the Earthball, as well as the Earthball itself) is counted towards the score from a single dunking.  (Randall may or may not know exactly how many basketballs there are, perhaps through research for some What-If question or other, but almost certainly assumes that there are no basketballs ''not'' on Earthball, even without allowing for recursion.  But there might be some question about whether the Earthball's own sub-scale basketballs are within code.)&lt;br /&gt;

In this comic [[Cueball]] is repeatedly attempting to make the comparison that for the {{w|Earth}}-{{w|Moon}} system, the Moon would be about the size of a {{w|baseball}} for an Earth the size of a {{w|basketball}}. &lt;br /&gt;

In the first interruption, [[Black Hat]] comes in and is amazed by this cool floating globe. Of course, being Black Hat, he has to make a digital prodding of this nice globe. But by putting his finger into one of the oceans of this &amp;quot;real&amp;quot; Earth, without a second thought, he thus generates a {{w|megatsunami}} of epic proportions, that rolls in over a large city, dwarfed at the foot of the wave.&lt;br /&gt;
&lt;br /&gt;
In the second interruption, [[Megan]] comes in and pours water from a half-liter bottle onto the Earthball, seemingly flooding its entire surface. Parallel to the first case, she would make an even worse tsunami, which would result in a similar fate of the Earth as during the {{w|Genesis flood narrative|flood from the Genesis}} where the human race was only saved by {{w|Noah's Ark}}.&lt;br /&gt;
&lt;br /&gt;
In the third interruption, a cat enters and playfully attacks the 'Earth'. But it will result in forces far greater than those exerted by Black Hat's digital prodding, and may have even taken the Earth out of its (representative) orbit.  One way or another, that will have resulted in (for us unseen) disasters of far greater proportion.&lt;br /&gt;
&lt;br /&gt;
The fourth interruption involves [[Ponytail]] taking the 'basketball' comparison at face value and actually trying to dunk the 'Earth' ''as'' a basketball.  This would ''not'' be good for any residents of Earthball who have yet to succumb to the events so far.  This simile-callback is continued in the title text with the idea that &amp;quot;every basketball in existence&amp;quot; (i.e. every basketball upon the Earthball, as well as the Earthball itself) is counted towards the score from a single dunking.  (Randall may or may not know exactly how many basketballs there are, perhaps through research for some What-If question or other, but almost certainly assumes that there are no basketballs ''not'' on Earthball, even without allowing for recursion.  But there might be some question about whether the Earthball's own sub-scale basketballs are within code.)&lt;br /&gt;

&lt;div&gt;&amp;quot;Old lady&amp;quot; names like Edith or Margaret are also pretty awful for a girl. She's gonna have to live her early years with a name that makes her sound like she's 50.

Remember that they are only &amp;quot;Old Lady&amp;quot; names because they were popular baby names 50 years ago! In 50 years time people will say don't name your child Hunter! That's a grandpa name!

I'm from Brazil and I find interesting that the concept of names that makes children feel much older exists in other languages. [[Special:Contributions/108.162.254.119|108.162.254.119]] 03:47, 29 January 2014 (UTC)&lt;br /&gt;

:It's common to pretty much all cultures, name fads come and go. In Brazil, for example, you don't see many girls named &amp;quot;Lourdes&amp;quot;, or old men named &amp;quot;Felipe&amp;quot;. --[[Special:Contributions/108.162.210.241|108.162.210.241]] 15:18, 2 February 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
:Interestingly this problem seems (to me) to be relatively unexistant in Poland. This seems to be helped by our attitude to name variants (i.e. considering them same name in most cases). [[Special:Contributions/141.101.89.216|141.101.89.216]] 21:06, 31 March 2014 (UTC)&lt;br /&gt;

I have a friend who was briefly called Parsley.  When she was born, her Grandfather got the call instead of her Grandmother, and reported that her name as &amp;quot;Parsley&amp;quot;.  He then went straight back to sleep, leaving the Grandmother quite frustrated.  After reading this comic, she felt sort of famous.&lt;/div&gt;</summary>

| number    = 1335&lt;br /&gt;

}}&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
The picture is divided in 24 segments representing the 24 hours of the day. The break between segments is not visible at noon or midnight because of the words, but presumably exists.&lt;br /&gt;
&lt;br /&gt;
The picture rotates by 3.75 {{w|degree (angle)|degrees}} every 15 minutes, as does the Earth, so that it is constantly up to date in showing which regions are currently at which times of day. The picture change seems to happen half-way through a 15-minute time increment (that is, at 7½, 22½, 37½, and 52½ minutes after each hour), so that the picture is always correct for the nearest multiple of 15 minutes.&lt;br /&gt;
&lt;br /&gt;
The map projection of the earth in the middle of the picture shows an {{w|azimuthal equidistant projection}} with the {{w|South Pole}} in the center.  This is unusual, as the projection typically puts the north pole in the center, but necessary in order for it to rotate clockwise. [[Randall]] was playing on projections before in [[977: Map Projections]].&lt;br /&gt;
&lt;br /&gt;
The list of cities and countries doesn't match the map exactly - notice how the continent of Australia is shifted far to the left of the words &amp;quot;most Australian cities&amp;quot;. This is because the map is centered relative to the {{w|time zone}}s and the local variations therein.  The map shows the configuration of time zones with respect to {{w|daylight saving time}} (also known as summer time) at the time of the comic's initial release (February 2014); it was being observed in parts of Australia, New Zealand, Brazil, and other countries not named in this comic. If the map were to stay accurate through the year, the location of place names would have to move over the next few months as parts of the southern hemisphere went off DST and parts of the northern hemisphere went onto it; however, the map failed to change on the morning of March 9 as it should have (to recognize the start of DST in North America).&lt;br /&gt;
&lt;br /&gt;
In many countries &amp;quot;{{w|business hours}}&amp;quot; are considered to be from 9&amp;amp;nbsp;am to 5&amp;amp;nbsp;pm. With some exceptions, including emergencies, it is generally considered rude to place a {{w|telephone}} call to someone's residence during the hours when most people are asleep; Randall portrays this time period as extending from 10&amp;amp;nbsp;pm to 8&amp;amp;nbsp;am.  This may be a reference to the 10&amp;amp;nbsp;pm &amp;quot;cutoff&amp;quot; time [http://www.youtube.com/watch?v=L0WeQJW-H3Y discussed] in an episode of &amp;quot;Curb Your Enthusiasm.&amp;quot; &lt;br /&gt;

When first posted, the picture was exactly 12 hours off. Somewhere around 5:10 UTC, this was fixed.  The original version also included a listing for Inland Brazil; this could have created a conflict with US East Coast when Daylight-Saving Time begins in the US, and it has been removed.&lt;br /&gt;
&lt;br /&gt;
The names used for the image files refer not to {{w|Universal Time|UTC (Universal Time)}} as one might expect but rather to the time exactly 12 hours off of that. The name of the image file linked from the page matched Universal Time during the first few hours, but the file-naming scheme did not change when the comic was corrected.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[The comic is a moving circle with a static outer ring.]&lt;br /&gt;
&lt;br /&gt;
:[The outermost part of the static ring is divided in 22 segments representing the 24 hours of the day. The Noon (11 AM - 1 PM) and Midnight (11 PM - 1 AM) segments cover two hours which are not segmented. The ring is divided so it is yellow from 6 AM to 6 PM and dark grey on the other half]&lt;br /&gt;
::Noon - 6 PM - Midnight - 6 AM&lt;br /&gt;
&lt;br /&gt;
:[The innermost part of the static ring is light grey and divided in two sections that cower from 9 AM to 5 PM and from 10 PM to 8 AM respectively. They  contain descriptions of the time intervals.]&lt;br /&gt;
::Business hours (9-5) &lt;br /&gt;
::Rude to call&lt;br /&gt;
&lt;br /&gt;
:[The rest of the image consist of a rotating part]&lt;br /&gt;
&lt;br /&gt;
:[On the innermost part of the circle is the Earth as seen from the south pole. Each continent has a different color. The colors are&lt;br /&gt;
:*Europe: Red&lt;br /&gt;
:*Africa: Cyan&lt;br /&gt;
:*Asia: Green&lt;br /&gt;
:*Oceania: Purple&lt;br /&gt;
:*North America: Blue-violet&lt;br /&gt;
:*South America: Olive green&lt;br /&gt;
:*Antarctica (The south pole): Light grey&lt;br /&gt;
&lt;br /&gt;
:[Two segmented rings circle the map - these give the names of the continents (not the Antactica) and the color of the ring match the color of the continent on the map. Each segment cover the part of the map with the given continent. The one with Europe is merged with the one for Asia - and the color also merges from red to green along Turkey and Russia where the transition from Europe to Asia occurs.]&lt;br /&gt;
&lt;br /&gt;
:[On the inner ring are the names of the following continents (white text on a segment with the color of the continent)]&lt;br /&gt;

&lt;br /&gt;

::Europe Asia &lt;br /&gt;
::North America&lt;br /&gt;
&lt;br /&gt;
:[On the outermost ring of the moving circle are written names of regions, countries and cities of the Earth over the part of the map in which time zone they belong. All the text is color coded to match the color of the continent they belong to as given on the central map. The text is written in four lines. Below the names are sorted by color and reading from left to right first - and only sorting top to bottom if needed]&lt;br /&gt;
