"Up to this point, magnetic monopoles were entirely theoretical"

Up to this point, magnetic monopoles were not supposed to exist. All electromagnetism can be derived from 4 Maxwell's equations, and one of them is div(B)=0, that means pretty much "there are not magnetic monopoles". I guess they should be able to see tons of unpredicted behaviors in that dyspro-whatever-spaghetti-thingy...

@Dirk Anger: Well, Dirac predicted that they might find monopoles in materials like this one, but materials like this one hadn't been inspected like this before. Another commenter mentioned that this is more of a quasi-monopole than an actual monopole, though, which is totally accurate.

As someone who had next to no clue as to how this stuff works prior to reading this, I couldn't help asking myself: "Why didn't they just try breaking a regular magnet in half?"

And then myself slapped me.

As a (former) theoretical particle physicist, I'm skeptical but hopeful.

An importance consequence of the existence of magnetic monopoles is Dirac's prediction that their existence naturally explains the quantization of electric charge, something that has puzzled theoretical physicists for a long time.

@ThisDudeRufus: Yes, that's why I remain skeptical. I've already contacted a few colleagues to find out what the general opinion is.

BTW, thank you for that link. According to it, these aren't *actual* magnetic monopoles, but quasi-particles, ie, an effective result of the interaction of other particles (magnetic dipoles in this case).

So, I remain skeptical.

@Roklimber: Just wanted to mention, Roklimber, that every time I post a physics story (specifically particle physics) I am always glad to see you encouraging people to think and learn about the stuff in the posts. I always shoot for as accurate an overview as I can give without being too dry or attempting a physics lecture, so I am always glad to see you continuing the discussion.

In short, kudos.

@phoghat: If someone had asked J. J. Thomson in 1897 what the practical use of his discovery of the electron was, or Dirac in 1928 when he theoretically predicted the existence of anti-particles, they would probably say that they didn't know. Yet, all of chemistry and all electronic equipment work because of electrons, and certain kinds of medical equipment use positrons (the anti-particles associated with electrons).

So, do I foresee a practical use for magnetic monopoles? I don't know, but I won't be surprised if we someday find many applications.

I remember once in a review of the movie PRINCESS MONONOKE in Science Fiction Chronicle their un-checked spell checker changed it to PRINCESS MONOPOLE. At least it was still kinda SFnal.

@ThisDudeRufus: My actual science is pretty weak compared to my science fiction. Authors use monopoles for propulsion systems (Larry Niven esp.) or for fusion energy. But that might just be like Geordie LaForge throwing tachyons at a positron beam to reverse the polarity of the hyperpickleator.

I'm sure one of our more edjumacated io9ers is about to Reveal All.

@cljohnston108: My first thought was Andre Norton's "Sargasso of Space" [en.wikipedia.org] which was published in 1955, pre-dating Larry Niven, I believe.
[I confess I may have the title mixed up with another Norton title which I cannot recall now - I read it about 30 years ago...]

@cadrina: Would you ask this question if they announced the discovery of gravitons or wormholes? An actual magnetic monopole would be a HUGE discovery for physics and could significantly advance our understanding of the universe.

I think that most people don't get what a big deal a magnetic monopole is because they don't show up in science fiction as often as some other, more popular theoretical whatsits... but seriously, the discovery of a real magnetic monopole should be a "Stop what you're doing right now and call all your friends and the Nobel committee while you're at it because we know who's getting all the prizes" kind of scientific discovery.

That said, what was actually discovered were "monopole-like quasiparticles".... so, interesting, but not as revolutionary as it first looked.

So, what are the applications? What can we use monopoles for? In Larry Niven's Protector monopoles were used in Singleships and made fusion power not only work but work more efficiently.
