Explain xkcd: It's 'cause you're dumb.
Cueball seems to be attending a meeting in a physics facility that has a particle accelerator. The Physicist asks him his thoughts about the Tertiary F.E.L guidance system that is a component of the particle accelerator. This sounds like the normal kind of jargon that you would hear in such a meeting.
As the text below the comic says, Cueball has spent the previous night reading the Simple English Wikipedia, a simplified version of Wikipedia intended to be easier to understand than the original, and now he finds himself talking in the same simple style. This makes him sound somewhat childlike and uneducated, but in fact he has clearly communicated the ramifications of relying on a sub-system that is known to be faulty. The accelerator would not perform its intended function, and may even be damaged.
From the title text, Randall believes that if people teaching advanced mathematics followed this style, their subject would be more accessible. The implication is that more people would be drawn to studying mathematics and that (naturally) the world would be a better place because of this!
This concept was later revisited in 1133 Up Goer Five.
add a comment!
- Friend: Do you have any thoughts regarding the particle accelerator's tertiary F.E.L. Guidance System?
- Cueball: We can't put the broken part in the machine. It wouldn't smash the right tiny things together. Then the machine might break.
- Cueball: That would be very bad.
- I spent all night reading simple.wikipedia.org, and now I can't stop talking like this.
This is possibly even another take by xkcd at conspiracy theories such as the one in http://xkcd.com/966/
- In this comic too he presents conspiracy theories against each other, the black hole with the guidance system.
The fact that the reference of something bad happening is to the Black hole theories comes from the fact that the comic was drawn the same time the theories were most predominant.

I don't think there's a joke here regarding "particle accelerators not having a guidance system" (paraphrasing the first paragraph of explanation, currently). Maybe there's a confusion about the phrase "the particle accelerator's tertiary F.E.L. Guidance System"? The FEL (Free Electron Laser, IIRC) itself is a tunable lasing 'cavity' for electrons that is magnetic, not optical, in nature, but (again, IIRC) is supplied with electrons at relativistic speeds by way of a particle accelerator (depending on which FEL, sometimes dedicated to the FEL and sometimes "from a main multipurpose ring", such as the LHC might be). Particle acceleration requires that the particles being accelerated be constrained within the ring (when being brung up to speed or collided within the ring's in-line experiment zones) or redirected out of the ring (or allowed to depart it, but still in a controlled manner) if being used for an out-of-ring experiment. It's true that particles being smashed are thrown together rather haphazardly (when compared, say, with collisions at the scale of vehicle crash tests), but there's actually quite a lot of sophisticated detection equipment used to work out the path of the particles so that guidance can be applied by magnetic fields (separately from the 'corner turning' ones and/or including those). I think I would consider such systems (including the ones that 'extract' particles for use in off-ring experiments) worthy of the title "guidance systems", albeit external to the particle as opposed to on-board like on a smart missile... And so if (and I haven't checked, so colour me wrong if I turn out to be so) the complex has at least three FELs attached, it's reasonable to assume that the third of these (hierarchically speaking) has, like its brethren, a particle guidance system involved at some point to ensure the electron supply is suitably contained and piped into it... Or it refers to the third of (at least three) beam-guiding systems for the lone FEL. Maybe even this means something active within the magnetic "wiggler" assembly of the FEL itself, or even (if this is what they do) on the output to the FEL leading into the LHC itself... But whichever it is, it the relevent FEL Guidance System surely exists in some form or other.
...TL;DR; - I'm pretty much sure the joke is more of an "Up-goer 5" nature... I also don't see any reference to Black Holes/conspiracy theories... It's just doing an "If this part is broken, you will not
go to space collide any particles today" thing, surely? 18.104.22.168 22:05, 27 May 2013 (UTC)

- I agree with 22.214.171.124. There's nothing about conspiracy theories, even indirectly. I've removed that part. I also don't see anything criticizing Simple English Wikipedia, or two versions. To the contrary, he praises it (albeit somewhat exaggeratedly) in the title text. I left it for now, though. Mattflaschen (talk) 08:44, 13 October 2013 (UTC)
