Astronomers snap black hole murder in graphic detail (video)
We tend to imagine a black hole sucking everything around it straight into oblivion. The truth, however, is even more gruesome. Astronomers have just captured an ultra hi-res image of our neighbouring galaxy, Centaurus A, and it helps to reveal what actually happens. Matter is yanked helplessly towards a black hole at the galaxy's core, but it refuses to die quietly. For some unknown reason, it erupts as it falls, spewing out vast plumes of particles -- like blood from celestial murder. These death throes emit radio waves, allowing us to witness them using radio telescopes even though we are 12 million light-years away. If only we were closer; if only we could intervene. Alas, all we can do is watch the video after the break and hit the source links for a fuller explanation -- though, admittedly, none of those sound like awful options.
String theory finds an elegant use for itself with qubit entanglement and black holes
Sure, trying to wrap your head around string theory -- a study in particle physics that's trying to rectify the perceived contradictions between general relativity and quantum mechanics -- can cause more cognitive pain than a colliding god particle. That hasn't stopped anyone from trying to validate its corollaries, and in the interim, researchers like Michael Duff of the Imperial College London. Mr. Duff realized a few years ago there existed some strong relations between formulas pertaining to both black holes (relativity) and four entagled qubits (quantum mechanics). So, in his words, "In a way, there's bad news and good news in our paper. The bad news is, we're not describing the theory of everything. The good news is, we're making a very exact statement which is either right or wrong. There's no in between." We're sure some science cliques are already gearing up to get their troll on.

Astronomers theorize what it's like when worlds (and black holes) collide
Tight binary solar systems are inhabited in science fiction -- remember the Star Wars world of Tatooine -- but humanity might find such planets inhospitable over the long term, and not just because of the heat. Using NASA's Spitzer telescope, scientists discovered clouds of dust around three such binary systems far too recent to come from the stars themselves, and theorize that as the stars attract one another over time and get closer and closer together, their respective orbiting planets may get closer as well, and crash into one another catastrophically. Meanwhile, when supermassive black holes dance in pairs, they can merge as one, and astrophysicists have recently simulated how such a joining might appear on our telescopes. According to a team of US and Canadian researchers, the pair may emit strong jets of electromagnetic radiation before they merge, which twist around one another and throw off gravitational waves that can help pinpoint the source. Speaking of sources, we've got plenty of those immediately below if you'd like to read more.
First electromagnetic 'black hole' built on earth, nobody raps about it
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.

EVE Evolved: Features we want in EVE Online
It's been a while since I've done a full-blown opinion piece but this week I figured it would make a nice change from yet more coverage of the recent Apocrypha expansion. No matter where you go in-game, everyone has their own opinion on what features EVE Online needs. For some people, being able to put mining rigs on planets would sound interesting. Others might prefer a new exploration-specialist science vessel or a module that gives resistance to energy neutralisers. There are a lot of ideas out there and some of us spend long nights chatting to friends in-game about the ones they'd like to see implemented. A few pilots have gone as far as to write up full scale proposals to present to CCP on the forum and some of those have even been implemented. This got me thinking – what features would I most like to see implemented in EVE?In this concise opinion piece, I take a look at the top four features I'd like to see make it into EVE Online. What's your top four?
CERN rap video about the Large Hadron Collider creates a black hole of awesomeness
Been having a tough time figuring out just what CERN's Large Hadron Collider does? Worried that it will create a Möbius strip (a rip in the fabric of space where time becomes a loop)? Just love to jam? Watch this CERN-sponsored rap after the break, and have your universe totally destroyed. Er, but not for real.[Via Protein Feed]
