I'm not knowledgeable enough in this area to critique these claims, but I'm guessing something like this is at play:

Where is my god now? Probably in some laboratory trying to invent something new instead of spending time with his family at home.

Aaaannnd we're done here.  Like you I know next to nothing about this, but I'd be willing to bet that the material only behaves like a universe would (clumping gasses into system, etc) and not be comprised of actual star systems and planets.

Unless of course a single tiny atom in my fingernail is a little...

tiny...

universe.

Actually, it gives a good representation of the paper, which is very light, only seven pages.

PonceAlyosha: Here's the paper in PDF form.


Thanks.

FTA: Extraordinary light rays propagating inside a hyperbolic metamaterial look similar to particle world lines in a 2+1 dimensional Minkowski spacetime

So not like our 3+1 dimensional Minkowski spacetime at all, then?

Summary of the paper: "We found a tabletop way to make a metamaterial with extraordinary optical properties that previously were much harder to create and play with. Then we sexed up the paper with a pointless and incomplete analogy that GNDN."

I think what they're doing is redefining the word "universe" to affirm their assertion.

Or it may be that "universe" in the way that scientists use it is completely different than "universe" the way everybody else uses it. Kinda like "theory".

Ishkur: I think what they're doing is redefining the word "universe" to affirm their assertion.


This here. They seem to be equating "region of the material that refracts as if it had a hyperbolic 2+1 geometry" with "actual hyperbolic 2+1 spacetime" which they then analogize to "universe". But it's not a spacetime at all -- at best, the light refracts in a path that resembles the path unrefracted light would take in a hypothetical hyperbolic 2+1 spacetime.

So the whole thing is pretty hyperbolic if you ask me.

Hyperbolic, get it? Like hyperbole?

Oh, never mind.

/Incidentally, creating a 2+1 geometry inside a material isn't nearly as exotic as it sounds, although it is still pretty damn cool.

Why would you expect it to have star systems and planets? We have those here because of the way our universe formed. With other rule sets, it doesn't happen. Even just the balance of matter and antimatter ... well.

Anyway. If you read the actual science-y thing, your guess is correct. It LOOKS SIMILAR TO is repeated multiple times. That's still pretty cool though, as it may allow observations that we couldn't muck with otherwise.

But yeah the main stream version is a bit misleading. Um, I guess the best analogy is to think about a tornado in a jar. You could [in theory] create something that LOOKS SIMILAR TO an actual tornado, and using that model learn things/conduct observations and experiments you couldn't do with an actual tornado, while having something that behaves just like one. Hope that makes sense. I haven't had coffee in this multiverse yet. ;)

PonceAlyosha: Here's the paper in PDF form.


Yeah, I read the paper and it seems that they were able to generate domains in a solution with a ferrofluid using a magnet and are claiming that there is a resemblance to a multiverse.  I personally don't buy it, I think it's really more like generating colloid suspension with magnets (woohoo?). It's seems like a pretty weak paper and if I were to review it I wouldn't recommend it not be published.

/Doesn't expect to see this in a real journal anytime soon.

Some people think hyperbole is the greatest thing ever. Me, I think it's worse than the Holocaust.

Silly physicists, you don't need ferrofluids to cook up a mulitverse of universes.  An account at the fanfiction website of your choice is much cheaper.

From Wikipedia:  Minkowski space is often contrasted with Euclidean space.

So... what they're saying is it is non-Euclidean? What have they done?!

I plotted out a hyperbole once. Unfortunately it was supposed to be a parabola and I ended up just slinking quietly back to the School of Liberal Arts.

This is good news!  I have been trying to create a 2+1 geometry with the two girls in the apartment downstairs.  Their response was, "Maybe, in another universe." I'm getting closer!
