The crisis could come from a more abstract feeling thinking of the incinerating/trash devices as Ouroboros, serpents biting their own tail or nilpotent matrices. Nothing would be left. Sebastian --[[Special:Contributions/162.158.88.62|162.158.88.62]] 06:01, 8 April 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
There also might be a more practical explanation of the crisis; in my experience it is extremely difficult to convey to trash collectors that a garbage can itself is part of the trash. Merely placing it inside another, larger trash receptacle is often not enough to convince them to collect it.

:I actually had the opposite problem recently, where we obtained a medium sized plastic tote with a recyclables logo on the side, and they were kind enough to take all the recyclable materials, apparently including the tote.

:Sadly, that might not have been the trash collectors.  That is, I'm sure they took the recyclables, but it's possible one of your neighbors said, &amp;quot;Hey, free tote,&amp;quot; especially since if it was new, clean, and did not have any identifying marks, such as your address, on it.&lt;br /&gt;

Disposing of a trash can by putting it in its replacement is simply insustainable: After a few generations, you end up with a container that won't fit trough your door! --[[Special:Contributions/162.158.91.173|162.158.91.173]] 13:09, 9 April 2017 (UTC)&lt;br /&gt;

:Well, it's not technically chocolate, but it is a derivative -- insert math joke -- and the chart doesn't seem to be concerned with what it is, just with what it's called; after all, that which is called white chocolate by any other name would taste just as sweet, putting some off while others enjoy it.

I suspect this is Randall's take on Fake News™, since it contains verifiably false claims such as coffee and liquorice being bad, and candy floss being better than watermelon&lt;br /&gt;
&lt;br /&gt;
[[Special:Contributions/141.101.107.66|141.101.107.66]] 16:12, 15 March 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
&amp;quot;In the title text, Randall asserts that his rankings of colors and foods are indisputable (with the exception of chocolate). This is of course ridiculous, as everyone knows that watermelon and strawberry are inherently superior to the likes of Citrus Fruits.&amp;quot;...but his rankings of strawberry and of watermelon (x2) are higher than for oranges, lemons, and limes.  There is no contradiction here; nothing that is ridiculous. [[Special:Contributions/162.158.78.118|162.158.78.118]] 16:29, 15 March 2017 (UTC)&lt;br /&gt;

:: Sweet liquorice, or salted? I'm pretty sure there should be two dots there. Also, coffee and chocolate are both missing from the right end of the 'black' row. Most of the others, I think I'd flip the line, but keep each line in the same place.

Hmm. The selection seems quite diverse compared to a standard bag of jelly beans, but doesn't really cover the range of a gourmet brand. I wonder where root beer falls, or Dr Pepper. And that's not even getting into color classification when the bean has more than one color. Personally, when I used to get gourmet jelly bean brands, I would do the squeeze-and-sniff test on a particular shade of brown, because it was used for both coffee and a flavor I liked. I remember Lore Sjöberg having a similar problem with cinnamon and cherry, but if he ever arrived at my solution, I don't know. [[User:Nyperold|Nyperold]] ([[User talk:Nyperold|talk]]) 16:44, 15 March 2017 (UTC)&lt;br /&gt;

:Interesting theory that he's talking about flavors of jelly beans, though there's really nothing to indicate he is.  But I believe every one of those food flavors are included in, for example, Jelly Belly's lineup (with the possible exception of a White Chocolate flavor).

If it is jelly beans it is definitely more agreeable then actual food. Because popcorn jelly beans are awful which explains why there a outlier. It also explains why there split by color.{{unsigned ip|172.68.58.89}}&lt;br /&gt;

My tastes now rate sweet tastes poorly - as well as sour, so I would down rate candyfloss, but not up rate lemon.  The variability of chocolate represents the range from choc flavoured sweet margarine, through to 90% coco solids.  My peak preference being about 50-60%.

Wait, lemons? I like lemons. Anyone with an excess of raw lemons for eating should send me them. I would eat them consistently if it weren't for the fact that doing so makes my gums sore afterwards. I've several times distilled lemon juice into a much, much stronger &amp;quot;lemon syrup&amp;quot; with about 1/10th the volume and the consistency of maple syrup, and my general feeling is that I would eat it like candy if it were widely available, even though it has virtually no sugar in it.

::::And assuming &amp;quot;mid 20th century&amp;quot; refers to World War II of 1939-45 (less years for Americans, arguably more so for some other countries), there were already gun-attached 'fighter aircraft' in WWI and onward (though often technically called &amp;quot;scouts&amp;quot; or &amp;quot;pursuit&amp;quot; aircraft, in English and American terminology, respectively... other countries/languages having their own varients).  Maybe not from the ''very'' start of the 1914-18 conflict, as opposing aircrews were apparently quite friendly to each other for a while until some air-reconnaissance pilot took a pistol up with him (or perhaps it was originally a solution against airships, leastwise those that they could get high enough to attack).  And then some people had the idea to hard-attach various projectile weapons to the planes.  And, oh boy, they had fun for a while trying to mount them to fire through their own front propellers, didn't they? ;)&lt;br /&gt;

A {{w|meteor}} (follow the link!) ''is not'' an intermediate stage in the lifespan of a chunk of rock between a meteoroid and a meteorite; it is the streak of light ''produced'' by a meteoroid during its descent through the atmosphere.

Nice. A lot of meteorites on the earths surface today come from broken apart, differentiated asteroidal parent bodies so they ''were'' magma once. The rocky planets have grown through accretion of meteorites so all of the earths magma used to be elsewhere in the solarsystem at the very start. Plus, with temps so high under the crust, anything found down there would be molten and dissolved in the magma anyway and called such.

&lt;div&gt;Even if you placed the mirror in Space, it would be incredibly obvious what is going on. I don't think this would work. [[Special:Contributions/96.251.85.48|96.251.85.48]] 06:56, 28 June 2013 (UTC)&lt;br /&gt;

:For this trick to work, the mirror would need to be placed AT LEAST two light years away and be at least 1AU big. Somehow I don't think this is worth it. Alternatively, you need more complicated optical system which would not only mirror Earth, but also create illusion it's further away. I still think such system would be more costly to build that ISS. Or ... well ... you could put an LCD display directly over the telescope. That's doable, cheap and as a bonus you can display planets from sci-fi there. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 08:44, 28 June 2013 (UTC)&lt;br /&gt;

Since when do we have terrestrial telescopes that can directly resolve exoplanets? I think we're still at the stage where we get excited by troughs in light curves EDIT: TIL that there are specific techniques for exactly that: {{w|Nulling interferometry}} and {{w|Vortex coronagraph}}s. Still, they may work for hot Jupiters, but don't think we can detect Goldilocks exoplanets from the ground yet; much less see oceans and visible weather.

My first thought was that you need to point the mirror so that it's aimed perfectly at the Earth. Then, I realized that you can use a corner reflector so that the aim doesn't have to be precise at all. Then, I came to the following realization: what if a significant portion of the stars we see are simply reflections of our own solar system due to a massive prank done by aliens?

::: What if there's a mirage-like effect in space, that causes light rays to mirror back to us with some variability, maybe different sizes, shapes, colors, and the universe is actuallly quite small?

&lt;br /&gt;
: Depends on how far the aliens decide to put the mirror. Light gets weaker with distance, which is the same reason that distant stars (many of which are brighter than our sun) don't overwhelm us with light.

''&amp;quot;The argument between exploring space vs saving resources and solving problems on Earth is a pretty common modern one, both in theory, and in practice.&amp;quot;''&lt;br /&gt;
&lt;br /&gt;
Actually, we shouldn't have started expanding our species out of Africa before predicting (and allowing for) the development of Religious Hatred, Mechanised Warfare and Oppressive Copyright Practices...{{unsigned ip|86.10.119.75}}&lt;br /&gt;
:Personally, I usually quickly send my initial Zulu forces up to blockade the land-bridge in the vicinity of Egypt, and ''then'' expand out throughout Africa so as to allow me to develop my own superior navy (and as many wonders as I can, including the library) before anyone else gets there.

This attacks a rather typical conservative attitude that we shouldn't &amp;quot;waste&amp;quot; resources on &amp;quot;minor&amp;quot; problems when there are bigger problems to deal with. (e.g., &amp;quot;Why are you giving me a ticket for speeding when there are murderers out there you should be catching?&amp;quot;) The title text pinpoints the fallacy of it (if you only ever work on the biggest problems, you will never solve that problem and also never accomplish anything else)   [[User:JamesCurran|JamesCurran]] ([[User talk:JamesCurran|talk]]) 16:10, 1 July 2013 (UTC)&lt;br /&gt;

I have issue with 'The comic is, at its core, a parody of the overly optimistic scientism that often attaches itself to the idea of a manned Mars mission, which in the minds of its supporters is always &amp;quot;ten to fifteen years away,&amp;quot; no matter the unsolved technical or logistics challenges that are still standing in the way.'  I think it's the converse.  The overly optimistic ''semi-''scientism that if we put something like Mars exploration on hold that the resources this frees up would be instantly transferable into &amp;quot;solving all the world's ills&amp;quot;.  The ten-to-fifteen-year span is then the (sarcastic?) suggestion as to how long this would need to be done for, before we can consider them all solved and start pumping the same resources back into space missions and pick up from where we leave off.&lt;br /&gt;
:I agree that the 'The comic is, at its core, a parody of the overly optimistic scientism that often attaches itself to the idea of a manned Mars mission, which in the minds of its supporters is always &amp;quot;ten to fifteen years away,&amp;quot; no matter the unsolved technical or logistics challenges that are still standing in the way.' line is not a correct analysis of this comic.

(Reminds me of my typical Civilization-playing scenario, pumping lightbulbs into one or other single scientific advance, but switching the target when realising I would ''quite'' like something else researched (perhaps for its associated military unit), even though it wasn't my original plan on the way to (perhaps) the Alpha Centauri win.  Or, more generally, jumping between all 'spare population' being scientists and them all being entertainers or tax collectors, for a few turns, to deal with morale or cashflow problems while a corrective Wonder is being built...  then once it's done I'm free to blithely make it 100% Science again, if I've got such a max/min playing style at the time...)

&lt;br /&gt;
Great(!)  Made a unanimous decision to make the change I intended (the &amp;quot;Fuggit!&amp;quot;-labelled edit), after apparently no-one else having an opinion about the need to switch the focus round, and then quickly a set of ''other'' edits occur that don't even revert things back (which I wouldn't have minded).  Anyway, don't want to cause an Edit War by reverting/de-reverting/etc, so I'm leaving the following here for your combined consideration.&lt;br /&gt;
&lt;br /&gt;
Mr (or Ms) 149.32.192.33 who &amp;quot;removed the comment about (...) the Mars Mission&amp;quot;.  You didn't remove anything explicitly about Mars, as I'd already removed that reference and re-edited that section (check what I did in http://www.explainxkcd.com/wiki/index.php?title=1232:_Realistic_Criteria&amp;amp;diff=prev&amp;amp;oldid=42725) and of all the edits I made , I actually quite liked that bit of rare non-waffling.  I propose we re-add text similar to:&lt;br /&gt;
 The comic is, at its core, looking at the idea that space exploration is something we can ill-afford to fund whilst there are so many Earth-based issues that need to be addressed.&lt;br /&gt;
It's indicating White-Hat's views, and is neutral about whether this is a ''sound'' idea or not.  (The rest is maybe more forceful, as I'm personally definitely not an &amp;quot;Earth-only&amp;quot; person, although I'm not extreme in the other direction either so hopefully created balance.)&lt;br /&gt;
&lt;br /&gt;
My thanks to the typo-corrector (I'm always mistyping &amp;quot;lieu&amp;quot;, it seems).  Although &amp;quot;spaceborne&amp;quot; seems more correct to me than the hyphenated version.  &amp;quot;Space-born&amp;quot;, yes (born of space, e.g. a person of said heritage), but &amp;quot;airborne&amp;quot; is a word in my dictionary, so...  Anyway, I've no excuse when I used &amp;quot;seem&amp;quot; instead of &amp;quot;seam&amp;quot; as the root of another word.&lt;br /&gt;
&lt;br /&gt;
Dgbrt: Good reduction of my waffle (surrounding my oblique reference to Teflon), but I'm saddened to lose the general (if not always proven) examples and your edit perhaps goes explicitly pro-Space more than I'd intended.  Still, it's shorter and more readable.  I don't understand the criteria for &amp;quot;Trivia&amp;quot; enough to understand if that'd be a more suitable locale for what was removed.  (But suspect it wouldn't be for the purely hypothetical asteroid-avoiding scenario.)&lt;br /&gt;
&lt;br /&gt;
And I know this is potentially a hot-topic.  Hence why I used loads of words to try to indicate that it ''is'' a hot-topic, that almost everyone could have an opinion about.  (Even exclusing the totally uninformed, &amp;quot;for every expert there's an equal and opposite expert&amp;quot;, so I tried to make sure everybody understood why they might find the explanation neither too pro-Space or too anti-space, depending on their defauly stance.) But for now I shall leave it as is. [[Special:Contributions/178.98.53.132|178.98.53.132]] 15:58, 2 July 2013 (UTC)&lt;br /&gt;

Please try to add your content in a proper way, people will NOT read this chaos. But even if they do, they still do not understand what you're talking about. At this moment this explain is chaos and so it is incomplete.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:41, 2 July 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
Ok, chaos indeed, and I don't pretend to understand the edit-history progression.  (When did the Mars Mission get specifically reintroduced?  Perhaps I don't care.)  How about something ''quite'' brief like...&lt;br /&gt;
 White Hat is suggesting that the exploration of space and other planets is a luxury that we should not yet be dedicating resources to when there are so many other things for which the resources could apparently be similarly used.&lt;br /&gt;
 Cueball agrees, possibly disingenuously, then asks how long it would be for a society purely focussed upon Earth-problem solutions to implement the necessary answers, allowing us to renew spending on the aforementioned luxuries without cause for complaint.  The Title Text errs towards the lengthier period, almost certainly tongue in cheek regarding the ease of such an approach.&lt;br /&gt;
 It is probably a simplistic point of view that funding and work currently dedicated to the space sciences are fully transferable away from this area and towards creating a utopian ideal on Earth, on a whim.  It also unfairly discounts the very real possibility that large tracts of research and practical engineering might indeed have useful Earthly applications, but without the driver of 'space' may never be undertaken in the first place.&lt;br /&gt;
Then perhaps a final paragraph about Real Life not being a game where, turn by turn, the entire scientific apparatus can be diverted from one 'tech tree' target to another without causing stumbling blocks. And that we don't even have a well-defined Tech Tree, and sideways propogation of ideas is rife. Purely non-space research is as self-destructive to advancement as much as single-mindedly purely pursuing its space-targetted counterpart to the exception of environmental protection, food production, etc.&lt;br /&gt;
&lt;br /&gt;
Paragraphs 1 and 2 of this suggestion explain the &amp;lt;strike&amp;gt;obvious&amp;lt;/strike&amp;gt; direct content of the comic.  Paragraph 3 deals with the issue raised (I'm very much assuming Cueball and the Title Text are being as sarcastic as White Hat is being earnest).  Anything else could be considered mere opinion, but perhaps can still be kept neutral.  But someone else might have better wording for all of it.

&lt;br /&gt;
This is my first post, so I'm not sure if it's appropriate to discuss the underlying theme. If not, please let me know. Anyway . . . &lt;br /&gt;
&lt;br /&gt;
Historically, for my ancestors at least, exploration and expansion to new frontiers did a lot more to solve their problems than any government programs. They came to America during the potato famine, climbed into a covered wagon and headed west. &lt;br /&gt;

Say to me we need the money &amp;lt;br /&amp;gt;&lt;br /&gt;
Just to feed the poor,&amp;lt;br /&amp;gt;&lt;br /&gt;
And I say, 'Gee that's funny,&amp;lt;br /&amp;gt;&lt;br /&gt;
It's for them that we explore.'&amp;lt;br /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Say to me we should be fighting,&amp;lt;br /&amp;gt;&lt;br /&gt;
Say to me the world's at war.&amp;lt;br /&amp;gt;&lt;br /&gt;
And I say we are uniting&amp;lt;br /&amp;gt;&lt;br /&gt;
