A new discovery runs counter to most observations about black holes, which are massive areas of space with extraordinarily strong gravity that can pull in anything — even light. In most cases, black holes and their host galaxies expand at the same rate. But astronomers have spotted a super-sized black hole in the early universe that grew much faster than its host galaxy.
This particular black hole formed in the early universe, roughly two billion years after the Big Bang. An international research group made the discovery during a project to map the growth of supermassive black holes across cosmic time. The team included astronomers from Yale University, ETH Zurich, the Max-Planck Institute in Germany, Harvard University, the University of Hawaii, INAF-Osservatorio Astronomico di Roma, and Oxford University.
“Our survey was designed to observe the average objects, not the exotic ones,” said C. Megan Urry, Yale’s Israel Munson Professor of Astrophysics and co-author of a study about the phenomenon in the journal Science. “This project specifically targeted moderate black holes that inhabit typical galaxies today. It was quite a shock to see such a ginormous black hole in such a deep field.”
Deep-field surveys are intended to look at faint galaxies; they point at small areas of the sky for a longer period of time, meaning the total volume of space being sampled is relatively small.
This particular black hole, located in the galaxy CID-947, is among the most massive black holes ever found. It measures nearly 7 billion solar masses (a solar mass is equivalent to the mass of our Sun).
However, it was the mass of the surrounding galaxy that most surprised the research team. “The measurements correspond to the mass of a typical galaxy,” said lead author Benny Trakhtenbrot, a researcher at ETH Zurich’s Institute for Astronomy. “We therefore have a gigantic black hole within a normal-size galaxy.”
Most galaxies, including our own Milky Way, have a black hole at their center, holding millions to billions of solar masses. Not only does the new study challenge previous notions about the way host galaxies grow in relation to black holes, it also challenges earlier suggestions that the radiation emitted by expanding black holes curtails the creation of stars.
Stars were still forming in CID-947, the researchers said, and the galaxy could continue to grow. They said CID-947 could be a precursor of the most extreme, massive systems observed in today’s local universe, such as the galaxy NGC 1277 in the Perseus constellation, 220 million light years from the Milky Way. But if so, they said, the growth of the black hole still greatly anticipated the growth of the surrounding galaxy, contrary to what astronomers thought previously.
Urry and her colleagues credited the W.M. Keck Observatory in Hawaii and the Chandra COSMOS legacy survey in aiding the team’s work. “The sensitivity and versatility of Keck’s new infrared spectrometer, MOSFIRE, was critical to this discovery,” Urry said.
The black hole at the center of the super giant elliptical galaxy M87 shoen at the top of the page in cluster Virgo fifty million light-years away, is the most massive black hole for which a precise mass has been measured -6.6 billion solar masses. Orbiting the galaxy is an abnormally large population of about 12,000 globular clusters, compared to 150-200 globular clusters orbiting the Milky Way.
The team theorized that the M87 black hole grew to its massive size by merging with several other black holes. M87 is the largest, most massive galaxy in the nearby universe, and is thought to have been formed by the merging of 100 or so smaller galaxies. The M87 black hole’s large size and relative proximity, astronomers think that it could be the first black hole that they could actually “see.”

Susan Schneider of the University of Pennsylvania is one of the few thinkers—outside the realm of science fiction— that have considered the notion that artificial intelligence is already out there, and has been for eons.
Her recent study, Alien Minds, Schneider asks: “how might aliens think? And, would they be conscious? I do not believe that most advanced alien civilizations will be biological, Schneider says. The most sophisticated civilizations will be postbiological, forms of artificial intelligence or Alien superintelligence.”
Search for Extraterrstrial Intelligence (SETI) programs have been searching for biological life. Our culture has long depicted aliens as humanoid creatures with small, pointy chins, massive eyes, and large heads, apparently to house brains that are larger than ours. Paradigmatically, they are “little green men.” While we are aware that our culture is anthropomorphizing, Schneider imagines that her suggestion that aliens are supercomputers may strike us as far-fetched. So what is her rationale for the view that most intelligent alien civilizations will have members that are superintelligent AI?
Schneider presents offer three observations that together, support her conclusion for the existence of alien superintelligence.
The first is “the short window observation”: Once a society creates the technology that could put them in touch with the cosmos, they are only a few hundred years away from changing their own paradigm from biology to AI. This “short window” makes it more likely that the aliens we encounter would be postbiological.
The short window observation is supported by human cultural evolution, at least thus far. Our first radio signals date back only about a hundred and twenty years, and space exploration is only about fifty years old, but we are already immersed in digital technology, such as cell-phones and laptop computers.
Devices such as the Google Glass promise to bring the Internet into more direct contact with our bodies, and it is probably a matter of less than fifty years before sophisticated internet connections are wired directly into our brains.
via Muslim Groups Have Raised Over $52,000 to Repair Burned Black Churches | Colorlines.
by Sameer Rao – Thu, Jul 9, 2015
In a strong showing of cross-faith solidarity, a group of Muslim organizations joined to raise funds supporting the rebuilding of predominantly black churches in the South that were hit by devastating fire damage after the Charleston massacre. Only a week old, the campaign has surpassed its initial fundraising goal of $50,000 and been profiled in publications ranging from Mashable and Buzzfeed to RT and Al Jazeera America.
The campaign, started during Ramadan, was founded by a network of organizations and activists that include Ummah Wide, Muslim ARC and the Arab American Association of New York. The campaign, according to its fundraising page, was launched out of an obligation to both help communities of faith rebuild and to uplift racial and religious justice. mentioning the#WhoIsBurningBlackChurches Twitter campaign as well:
As Muslims we know the importance of protecting the vulnerable and respecting people who call on God in their various tongues. We want for others what we want for ourselves: the right to worship without intimidation, the right to safety, and the right to property. We must always keep in mind that the Muslim community and the black community are not different communities. We are profoundly integrated in many ways, in our overlapping identities and in our relationship to this great and complicated country. We are connected to Black churches through our extended families, our friends and teachers, and our intertwined histories and convergent present. Too often cowards inflict us with a crippling fear, but with encouragement and support from likely and unlikely places fear cannot stop us.
The campaign is encouraging people to use #WhoIsBurningBlackChurches on Twitter. The hashtag has been used widely all over social media by those demanding an explanation and full investigation of the fires. The page further includes a statement from noted theologian Imam Zaid Shakir, who implored American Muslims to support the churches out of a sense of shared suffering:
“The American Muslim community cannot claim to have experienced anything close to the systematic and institutionalized racism and racist violence that has been visited upon African Americans. Unless, of course, we are talking about those of us who members of the African American Muslim community. As a whole, however, we understand the climate of racially inspired hate and bigotry that is being reignited in this country. We want to let our African American brothers and sisters know that we stand in solidarity with them during this dark hour.”

WoodrowWilsonCenter
Published on 12 May 2015Most people assume that a Google search can identify most of the information available on a given subject. But beyond the capabilities of Google or any other search engine, there is another online world. In fact, the number of non-indexed internet sites is estimated to be 500 times larger than what a search engine can reveal. And where the sun doesn’t shine, there exists a dark side of the Internet that is a conduit for all types of illegal and often dangerous activity. Wilson Center Public Policy Fellow, Daniel Sui is attempting to uncover the web’s dark underbelly and begin the process of charting the uncharted. That’s the focus of this edition of Wilson Center NOW.
