Billions of times the mass of our own sun, so-called massive black holes present a baffling mystery with clues hidden at the very dawn of existence.
Simulation of the formation of a galaxy similar to our Milky Way. Massive black holes lurk in the centers of many of the building blocks that merge to assemble the galaxy, and a black hole also inhabits the final galaxy. Still from video release.

EnlargeBlack holes have long been cosmic mysteries, even as research in the past decade has shed some light on the largest of these dark objects and how matter pours into them.

Scientists say the many remaining puzzles include how the largest black holes were born at the dawn of the universe and how black holes may help shape the fate of galaxies.
"The whole field of 'massive black holes in galaxies' really developed in its own right in the last 12 years, and now it's one of the hottest in astronomy," Marta Volonteri, an astrophysicist at the Institute of Astrophysics in Paris, told SPACE.com. Volonteri is the author of a study on the evolution of the largest?black holes?appearing in the Aug. 3 issue of the journal Science.
Black holes have gravitational pulls so powerful, nothing can escape, not even light. Astronomers began mulling over the possibility of black holes in 1783, and scientists used Einstein's theory of general relativity to predict black holes in 1916.
Astronomers know of two "flavors" of black holes: "stellar-mass," which are up to a few dozen times the mass of Earth's sun, and "massive," which can be billions of times the sun's mass ? nearly the mass of all the stars in the entire Milky Way galaxy. Stellar-mass black holes are known to be the remains of dead stars, but it remains a mystery how the far-more-massive black holes formed. [Photos: Black Holes of the Universe]
One of the most popular theories about the formation of massive black holes links them with the first generation of stars. However, recent simulations suggest these stars were no more than a few dozen times the sun's mass, Volonteri said ? too small to easily achieve the mass of the largest black holes.
One alternative scenario proposes that massive black holes originated from stars up to 1 million times the sun's mass born from gas that rapidly accumulated over less than about 2 million years. Another model suggests the kernels of massive black holes were born from dense clusters of stars in the centers of galaxies that merged to form stars up to a few thousand times the sun's mass, which in turn collapsed to create black holes.
Curiously, astronomers recently discovered that billion-solar-mass black holes existed when the cosmos was less than a billion years old. Scientists are at a loss to satisfyingly explain how such massive black holes could have formed so early in the universe's history.
After a certain point known as the Eddington limit, the energy released by matter rushing toward a black hole should halt the flow feeding that black hole, restricting how large it can grow. Although it is possible that billion-solar-mass black holes could have formed in less than a billion years after the Big Bang, "all odds must be favorable to the black hole, so only lucky black holes can make it," Volonteri said.
Scientists are now exploring whether or not black holes can overcome the Eddington limit and grow at so-called super-Eddington rates. "That would make black hole growth easier," Volonteri said.
It remains a hotly debated question whether these massive black holes dominate how their galaxies grow or vice versa. Perhaps the energy these black holes release alters the overall evolution of galactic structures, or perhaps galaxies control how much gas falls into these black holes and thus regulate how large they grow. Another possibility is that massive black holes and their galaxies develop symbiotically.

(Reuters) - MasterCard Inc's
Net income rose to $700 million, or $5.55 per share, from $608 million, or $4.76 per share, a year earlier.
Revenue rose 9 percent to $1.82 billion. On a constant currency basis, revenue rose 13 percent.
The card network also took a pre-tax charge of $20 million, related to its share of the settlement in the 'swipe fee' lawsuit.
Excluding the charge, the company earned $5.65 per share.
Analysts on average had expected a profit of $5.58 per share, excluding items, on revenue of $1.87 billion according to Thomson Reuters I/B/E/S.
MasterCard, along with rival Visa Inc
MasterCard had already set aside $770 million to cover most of its $790 million liability.
SPENDING GROWTH SLOWS
Cardholders made $661 billion of purchases worldwide, on a local currency basis, during the second quarter, up 13 percent. Worldwide purchase volume has grown at more than 15 percent for the last four quarter.
Card payments outside the United States grew 18.6 percent, in local currencies, compared with 8.7 percent growth in the United States.
The network has reported double-digit growth in U.S. card payments over the last year.
Card rival American Express also indicated slowing spending growth when it reported results last month.
Shares of the company, which has a market value of over $55 billion, fell 3 percent to $421.95 in trading before the bell. They closed at $436.57 on Tuesday on the New York Stock Exchange.

Wait. Scratch that.
?? You'll first need to boil some egg noodles or make a batch of 5 minute rice to serve this over, and then?you'll be ready to chow down. I love serving this with a green veggie or a side salad. It makes the perfect family-friendly meal!

Right on schedule, Microsoft has just announced on its Windows Team blog that Windows 8 has emerged from its long development and testing phase, and will soon be in the hands of manufacturers and OEMs for installation on new PCs and devices. Among those on the list to receive the final build (build 9200, if you were curious) are Lenovo, Acer, ASUS and Toshiba, though that's clearly just the tip of a very large iceberg.Source: http://feedproxy.google.com/~r/Techcrunch/~3/fe1DHd-417o/
