An
electromagnetic black hole -- which sucks in the light surrounding it -- has been built at Southeast University in Nanjing, China for the first time. The device works like cosmological black holes in that it has gravity which is intense enough to bend the surrounding space-time, causing any matter in the neighborhood to spiral inward and create the hole itself. The earth-built 'black hole' for microwave frequencies is constructed of 60 annular strips of
meta-materials (yes, that's the stuff of
invisibility cloaks). Each strip is an intricately etched circuit board which seamlessly and smoothly connects to the strips next to it, creating both a shell and absorber section to the device. When an electromagnetic wave hits the device, it is trapped and guided through the shell region toward the core, where it is absorbed. The device, which was created by Tie Jun Cui and Qiang Cheng, converts that absorbed light into heat, meaning that future possible applications could include new ways of harvesting solar energy.

truly bad dude.

That's... kind of scary.
No kidding. This really is scary. If Meta Materials can create "electron black holes" then turning invisible IS possible, but, you'd appear as a huge gap in space.
That's one super-massive black hole.
If they at that bored, I suggest getting a girlfriend.
@ Eddy Munn
Don't worry, I got the Muse reference. Or in internet terminology: I see what you did there.
Kinda exciting. Now all those Stargate designs actually makes sense!
My theory is that I can use the electromagnetic field to create a new force engine that will power stuff like airplanes, cars, and etc but there's only one problem. It's not making it, it's actually how to make other vehicle gravity field from interacting from one another. Now if we can manage that, then it won't be a problem. =D
When I read about this a few days ago on new scientist I thought they said they hadn't managed to do this with visible light yet, which won't be easy... but should be possible.
It should be an interesting optical effect, if it works... but I wouldn't call it scary.
What if they make a bigger one and Earth gets sucked into it :O I DONT LIKE THIS!
Sure, you'd be invisible... except for the ginormous heat signature you'd put off.
Actually, you wouldn't see a giant gap where the invisible person was, the light would just bend around the person, and the things behind it would appear closer together, sort of like what those apple web cams do.
'cmon stick your finger in there.
Come one, do it. Stick your finger in there.
This device does not use gravity to "suck in" microwaves, it uses a clever materiel to funnel them towards the device's center. So, unless you or your favorite possessions are composed entirely of high energy electromagnectic waves, I think you're pretty safe.
This makes peoples flip outs over the LHC however many months back even more hilarious.
Oh well - us guys shouldn't complain, we can go back to being a shoulder to cry on!
Engrish fail.
Calling this a black hole is like calling the trashcan on your desktop a black hole, or a black t-shirt shirt.
Or your microwave oven, which also has a guide to guide waves and the cup of coffee absorbs the energy and turns it into heat.
So no this is not comparable to real risky stuff and real singularities or black holes.
What is exposed is your grasp of science though.
@Wwhat
Exactly... now if i may... FAIL!!
i see i see...but how and when will this help me a) become invisible or b) journey to other planets
Never. It can only help you get sucked into electricity plant, if you become light.
wut if it gets loose or something goes wrong and it starts 2 suck in everything and ends the world as we know it
It kinda makes the Chinese look comparatively innocent on the trade deficit and human rights then, doesn't it?
I, too, worry about your mother.
=P
STARGATE!!!
@ o.O
Except the Stargate isn't creating a "hole" it's creating a "string" between to points in space where matter is converted into pure energy and then re-integrated on the other side.
But we're one step closer to building our own Gatestation.
wormhole not blackhole
A wormhole is two blackholes put together the same thing
@Yeahitsme:
Bzzzt. Wrong answer. Two black holes are not a wormhole.
A wormhole is a "fold" (Explained using a 2-dimensional model) in space linking two sets of coordinates.
Black holes are a gravity field projected by a point of theoretical infinite density.
You might be thinking if the Einstein-Rosen bridge, but those were proved to be unstable from the moment of formation, and thus unusable even by light.
Amazing
THAT IS AWESOME!!!!
I see a backyard catastrophic accident in the futur ...
That's not likely to hap....
The Heene family of Fort Collins, Colorado is already on this. Some day soon we'll all be glued to our TV sets watching an invisible Brad Heene (the middle son) drive himself to the Denver Airport and attempt to sneak onto a flight to Cincinnati. Once there, he will work secretly as the mysterious "12th man" who helps the Bengals reach the Super Bowl.
i wouldn't be so s....
oh shi....
Looks like Candlejack has struck aga
So, basically, if you were to wear it, you'd boil to another universe in that suit? o_O

STOP it people, before we ALL Jus.5bh4 ?$% 3 , ___________ .
RUN FOR YOUR LIVES!
*gets sucked in*
This just in! It seems that prmd142 was a being comprised completely out of microwaves!
Film at eleven.
Well, everything is actually comprised of waves. This becomes apparent when you do a fourier transform and...
*Depressed "I know we're all gonna die" voice*
Run where????
Unlike black hole from the rest of the universe, these low quality knock reproductions made in China are full of lead.
And low quality plastic.
You'd expect a blackhole to suck everything in. This just absorbs the light that goes in it.
It's still a huge breakthrough though.
It comes bundled with a fortune cookie that says: "You will find yourself in a sticky situation in the wrong hole"
The thingie's design isn't specified by some American company, so probably not.
Blackhole KIRF?
