The technological singularity takes place when the human race succeeds in creating an A.I being more intelligent than any human could ever be. Let us call it Alpha. Since the act of creating Artificial Intelligence is a task that benefits directly from the intelligence level of the creator, this more-intelligent-than-men being would surely be faster and more efficient at creating his own A.I being, let us call him Beta. This second generation being would too be better than its predecessor, and could in turn create a third one, Gamma, who is even more powerful, and so on. As capacity increases, the median generation time decreases, resulting in an exponential rate of evolution that quickly becomes asymptotic, at which point it becomes difficult to speculate further.

The Semantic Web, a concept tossed around for years as a Web extension to make it easier to find and group information, is getting a critical boost Tuesday from the World Wide Web Consortium (W3C). W3C will announce publication of SPARQL (pronounced “sparkle”) query technology, a Semantic Web component enabling people to focus on what they want to know rather than on the database technology or data format used to store data, W3C said. The potential of the Semantic Web cannot be underestimated. By scanning the Web on behalf of users, even Google’s ad-based business model could be impacted, an analyst said. SPARQL queries express high-levels goals and are easier to extend to unanticipated data sources. The technology overcomes limitations of local searches and single formats, according to W3C.

It could be the weirdest and most embarrassing prediction in the history of cosmology, if not science. If true, it would mean that you yourself reading this article are more likely to be some momentary fluctuation in a field of matter and energy out in space than a person with a real past born through billions of years of evolution in an orderly star-spangled cosmos. Your memories and the world you think you see around you are illusions. This bizarre picture is the outcome of a recent series of calculations that take some of the bedrock theories and discoveries of modern cosmology to the limit. Nobody in the field believes that this is the way things really work, however. And so in the last couple of years there has been a growing stream of debate and dueling papers, replete with references to such esoteric subjects as reincarnation, multiple universes and even the death of spacetime, as cosmologists try to square the predictions of their cherished theories with their convictions that we and the universe are real.

The most massive known black hole in the universe has been discovered, weighing in with the mass of 18 billion Suns. Observing the orbit of a smaller black hole around this monster has allowed astronomers to test Einstein’s theory of general relativity with stronger gravitational fields than ever before. The black hole is about six times as massive as the previous record holder and in fact weighs as much as a small galaxy. It lurks 3.5 billion light years away, and forms the heart of a quasar called OJ287. A quasar is an extremely bright object in which matter spiralling into a giant black hole emits copious amounts of radiation. But rather than hosting just a single colossal black hole, the quasar appears to harbour two – a setup that has allowed astronomers to accurately ‘weigh’ the larger one.

In an e-mail sent to the Wikia Search mailing list on December 24, Wales wrote that he aims to make the initial version of the search tool available in alpha form. “We want to run over the system with help from people to complain about what is broken,” he wrote.
Wikia Search, which aims to allow people to contribute to how pages are ranked and to edit search results, will have open-source search algorithms and application program interfaces. The search platform includes the Grub search project, acquired by Wikia in July, which employs user-donated distributed processing power to crawl the Web.
Wales, who also co-founded user-generated online encyclopedia Wikipedia, hopes Wikia Search will eventually rival other search companies by making the way in which search results are arrived at more “transparent.”
