Hawking Radiation Claimed Created In a Lab
eldavojohn writes "In 1974, a young newcomer to the Royal Society named Stephen Hawking predicted that black holes emit Hawking Radiation. Researchers have been looking for it in space ever since. A new paper up for publication claims to have beaten searchers by observing it in a lab. Doing it wasn't easy. They say they brought light to a standstill by drastically increasing the refractive index of the material it was being fired at, creating a 'white hole.' This horizon, beyond which light cannot penetrate (event horizon), is the same between white and black holes, which caused the team to suspect they observed Hawking Radiation when light of a different uniform wavelength than the input laser was emitted. But, before you rejoice, the Tech Review article notes, 'Of course, the big question is whether the emitted light is generated by some other mechanism such as Cerenkov radiation, scattering or, in particular, fluorescence which is the hardest to rule out.'"
pics or it didn't happen
I read TFA and all I got was this lousy cookie

Well, to get a proper explanation of 'white holes', we really need to go to the experts:
Cat: So, what is it? ... back into the Universe? ... back into the Universe?
Kryten: I've never seen one before - no one has - but I'm guessing it's a white hole.
Rimmer: A *white* hole?
Kryten: Every action has an equal and opposite reaction. A black hole sucks time and matter out of the Universe; a white hole returns it.
Lister: So, that thing's spewing time
Kryten: Precisely. That's why we're experiencing these curious time phenomena on board.

Lister: What time phenomena?
Kryten: Like just then, when time repeated itself.
Cat: So, what is it?
[Kryten, Rimmer, and Lister stare at Cat]
Cat: Only joking.

...They say they brought light to a standstill by drastically increasing the refractive index of the material it was being fired at...
They tried to take pics but somehow there wasn't enough light..
i was on a really bad connection that was dropping packets left right and center.
So, you're saying that your information was falling into a black hole and you couldn't retrieve it from the event horizon???
Yeah I remember now... the story was intriguing and promising at the beginning and then it all went trough hell.
Nichelle Nichols: "It's about that rip in space-time that you saw!"
Stephen Hawking: "I call it a Hawking Hole."
Fry: "No fair! I saw it first!"
Stephen Hawking: "Who is the Journal of Quantum Physics going to believe?"
God Bless America!. Even in science, we can solve any problem by just shooting at it.
The real Sig captains the Northwestern. This one captains
Technology review's arXiv blog is so difficult to get any details out of. It's hard to figure out what these people have done. "frequency of 1055 nm"? I guess I'll have to go to the full article.
Yeah, and you know what's even worse? Some assholes report the mass of fundamental particles using electron-Volts which is a unit of *energy*, not mass. Retards.
Information theory is life. The rest is just the KL divergence.
So, Long story short is I'm not going to get a cool new device that replaces the microwave AND the trash compactor at the same time? I always let these headlines build my hopes for a better future... You'd think I would learn...

I would have posted a reply before simcop2387 did... time dilation is a bitch.
