Black holes may lurk in unexpected places

IT'S only a few hundred million years after the big bang. A star unlike anything we know is shining. It is so enormous it could swallow the present-day solar system with ease and so bright that it could outshine a galaxy of a trillion run-of-the-mill stars. Impressive as these characteristics are, they barely hint at the object's peculiarities. For in its heart a dark secret is hiding. As the outside of the star finally cools, like a dying ember, its outer layers are suddenly blown away into space. And there, uncloaked for the first time, is a monstrous black hole.

This composite image of M81 includes X-rays from the Chandra (blue), optical data from Hubble (green), infrared from Spitzer (pink) and ultraviolet data from GALEX (purple). The inset shows a close-up of the Chandra image where a supermassive black hole about 70 million times more massive than the Sun lurks. A new study using data from Chandra and ground-based telescopes, combined with detailed theoretical models, shows that the giant black hole in M81 feeds just like ones with masses of only about ten times that of the Sun.

Black holes not black after all

International scientists have used flowing water to simulate a black hole, testing Stephen Hawking's theory that black holes are not black after all.

Black Holes Don't Trap Information Forever

sciencehabit writes "New calculations suggest that black holes are not a one-way street. Anything that falls into them may eventually come out. The findings lend important support to quantum gravity, but fly in the face of Einsteinian relativity. They also support Stephen Hawking's reluctant admission that information couldn't be destroyed by black holes. Penn State researcher Ahbay Ashtekar was quoted saying, 'Once we realized that the notion of space-time as a continuum is only an approximation of reality, it became clear to us that singularities are merely artifacts of our insistence that space-time should be described as a continuum.' Let the physics infighting begin."

Proposed Mission Could Study Space-Time Around Black Holes

What do black holes, magnetars and supernovae have in common? They all emit X-rays. But it's difficult, if not impossible to study certain aspects of the X-ray emissions from these powerful objects. And there's much we don't understand about how black holes distort space-time around them, or how magnetars affect their surroundings, or how cosmic rays are accelerated by shocks in supernova remnants. A proposed new NASA mission called Gravity and Extreme Magnetism (GEMS), will use a new technique to study what has been unattainable until now. GEMS won't study the X-ray emission of these objects directly, but will build up a picture indirectly by measuring the polarization of X-rays emitted from these violent regions.

Why the LHC Won't Destroy the World

An anonymous reader writes "Most people are aware of the recent articles contending that the Large Hadron Collider at CERN might destroy the world. While most scientists have no such concerns, a recent preprint released to arxiv systematically dismantles the notion. The gist of the argument is this: Everything that will be created at the LHC is already being created by cosmic rays. If a black hole created by the LHC is interactive enough to destroy the world within the lifetime of the sun, similar black holes are already being created by cosmic rays. Such black holes would be stopped by dense cosmic objects (neutron stars and white dwarfs). A black hole stopped in one of these objects would eventually absorb it. We see sufficiently old neutron stars in the sky, thus any black hole that could be created at the LHC, even if it is stable, wo

A vision of Black seen through the eyes of Warhol

Fans of jailed former newspaper tycoon Conrad Black have a chance to view him up close and personal starting at the end of this week. One of four portraits of Lord Black painted by Andy Warhol will be on show for the summer at the Art Gallery of Greater Victoria, as part of a Warhol: Larger Than Life exhibition. Mr. Warhol painted the series in 1981 when Lord Black, then 37, was just starting to build his newspaper empire. The Black portraits are faring well in the open market. Last November, another of the same series fetched a higher-than-anticipated $240,000 at an auction at Christie's. Sadly, Lord Black did not receive any of the proceeds as he had been ordered by a U.S. court to give up two of the portraits as part of a legal battle with creditors of his former holding company, Ravelston.

How to Escape From a Black Hole

According to Einstein's theory of general relativity, black holes are regions of space where gravity is so strong that not even light can escape. And in the 1970's physicist Stephen Hawking asserted that any information sucked inside a black hole would be permanently lost. But now, researchers at Penn State have shown that information can be recovered from black holes.

Big Black Holes Cook Flambeed Stellar Pancakes

According to two astrophysicists from Paris Observatory, the fate of stars that venture too close to massive black holes could be even more violent than previously believed. Not only are they crushed by the black hole’s huge gravity, but the process can also trigger a nuclear explosion that tears the star apart from within. In addition, shock waves in the pancake star carry a brief and very high peak of temperature outwards, that could give rise to a new type of X-ray or gamma-ray bursts.

Stars Orbiting Close to Black Holes Flattened like Hot Pancakes

Playing with black holes is a risky business, especially for a star that is unlucky enough to be orbiting one. Assuming an unfortunate star hasn't already had all of its hydrogen fuel and other component elements stripped from its surface, the powerful tidal forces will have some fun with the doomed stellar body. First the star will be stretched out of shape and then it will be flattened like a pancake. This action will compress the star generating violent internal nuclear explosions, and shockwaves will ripple throughout the tormented stellar plasma. This gives rise to a new type of X-ray burst, revealing the sheer power a black hole's tidal radius has on the smaller binary sibling. Sounds painful…

Hunt for Black Holes Online

Cardiff University has created a new Black Hole Hunter game. In this game, you listen to audio files which are simulations of waveforms that might result from collisions of massive astronomical objects such as black holes and neutron stars. These signals are results of predictions based on theories of the gravitational waves that would result from such collisions, assuming that the theoretical gravitational waves do indeed exist.

China's online games paused to mourn earthquake victims

Shanghai. May 20. INTERFAX-CHINA - Chinese online game operators, including Shanda, The9, Tencent, Kingsoft, Giant Interactive and 9you, announced yesterday they would suspend all their online games for three days to mourn the victims of the recent earthquake in Sichuan Province. Shanda said it will resume its gaming services at 1:00 a.m. on May 22, while the other operators said their games will return on May 22, without revealing detailed times. On Sunday, China's central government called on the nation to suspend "public amusements" for three days beginning May 19 out of respect for the thousands of victims who died in the earthquake that shook Sichuan on May 12. Some Web sites, including Sohu, Baidu, Google China and Youku, have adjusted their front pages or logos to black and white as a mark of respect.

How Does Information Escape From Black Holes?

Physicists at Penn State have provided a mechanism by which information can be recovered from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking. The team's work will be published in the 20 May 2008 issue of the journal Physical Review Letters.
