Did anyone see that article about recreating a black hole event horizon using 2 different wavelength lasers and some fiber optics? Its seems quite clever....
I was hoping someone better at physics could explain it in simpler terms, the article a friend emailed me was quite complicated and hard to follow. I gave up physics after 2 years in university but still have an interest.... He seems to forget that unlike him I don't have a MSc in theoretical physics...

If you do find it post it here please.

Adam, the soliton men, you know more about this than me.
Originally posted by MexicoIn my opinion, saying this fiber optic stuff emulates a black hole event horizon is not consensual (to be nice). There might be an analogy somewhere, but I think people have to be more cautious in what they say.
True but what I got from it was that it can be taken as a proxy of the event horizon? . And that if they heat it up they should see the radiation hawking postulated......your better at physics than me thou
I do rocks...
And Volcanoes.... etc..
Scientists many times simply want to show results.
I had to know more details of the experiment to make a better critique. But I don't know condensed matter, non linear optics or black holes to guru level to say anything for sure here...
Originally posted by serigadoI think that this just what you said. The first soliton distorts the medium in a way that the second soliton is slowed down. If anythin I'd say this is a dynamic black hole approximation, From what I understood from the excerpt they have two solitons available. One slower and the other faster. First hey shoot the slower one and then the faster. Normally one would expect the faster one to catch up and at later times be ahead of the slow moving soliton. But the slower one distorts the medium where it is travelling, so this means that this a very strong nonlinear effect, and slows down the fdaster one. So when the faster one catches up it becomes tangled in the region more affected by the slower one and can't leave.

But without reading the propper article I can't tell much more. I tried to do a google search but couldn't find anything about this. 🙁
