    EnlargeGalaxy ESO 243-49, about 300 million light-years away, is home to the newly found black hole. Credit: NASA, ESA and S. Farrell (U. Sydney) (Phys.org) -- Over the years, cosmologists have found ample evidence of just two kinds of black holes: stellar mass black holes and supermassive black holes. The former are considered small by most standards, just several times the weight of our sun; the latter, as their name implies, huge and as heavy as millions of our sun combined. Not so easy to find have been those that lie somewhere in-between, and because of that, their existence...

    Boffins' first glimpse of the structural framework of our universe Higgs, Schmiggs... When that infinitesimal speck was sucking up all the journalistic oxygen on Independence Day, another momentous scientific discovery was also being announced: the first observation of filaments of dark matter, the stuff that forms the "skeleton" of our universe. Invisible, inexplicable dark matter makes up the vast majority of the mass of our universe. All the matter that we can see – stars, galaxies, planets, haggis, Michele Bachman – total only between 4 and 5 per cent of our universe's mass. The rest? There's dark matter and dark...

    Full title: Serious blow to dark matter theories? New study finds mysterious lack of dark matter in Sun's neighborhood The most accurate study so far of the motions of stars in the Milky Way has found no evidence for dark matter in a large volume around the Sun. According to widely accepted theories, the solar neighbourhood was expected to be filled with dark matter, a mysterious invisible substance that can only be detected indirectly by the gravitational force it exerts. But a new study by a team of astronomers in Chile has found that these theories just do not fit...

    GENEVA: Scientists at Europe's CERN research center have found a new subatomic particle, a basic building block of the universe, which appears to be the boson imagined and named half a century ago by theoretical physicist Peter Higgs. "We have reached a milestone in our understanding of nature," CERN director general Rolf Heuer told a gathering of scientists and the world's media near Geneva on Wednesday. "The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle's properties, and is likely to shed light...

    Physicists say they have all but proven that the "God particle" exists. They have a footprint and a shadow, and the only thing left is to see for themselves the elusive subatomic particle believed to give all matter in the universe size and shape. Scientists at the world's biggest atom smasher plan to announce Wednesday that they have nearly confirmed the primary plank of a theory that could restructure the understanding of why matter has mass, which combines with gravity to give an object weight. The focus of the excitement is the Higgs boson, a subatomic particle long sought by...

    The US particle collider Tevatron has jumped in just ahead of the Large Hadron Collider's results announcement this week to say that their machine has found the "strongest indication to date" of the God particle. The LHC's baby American cousin stopped bashing particles off each other back in March 2001 but the scientists have kept crunching the numbers from the 500 trillion collisions produced to wring the last drops of data out. Today, the boffins said their data "strongly point toward the existence of the Higgs boson" but we're still not there yet. “It is a real cliffhanger," the DZero...

    GENEVA (AP) — Scientists working at the world's biggest atom smasher plan to announce Wednesday that they have gathered enough evidence to show that the long-sought "God particle" answering fundamental questions about the universe almost certainly does exist. But after decades of work and billions of dollars spent, researchers at the European Organization for Nuclear Research, or CERN, say they aren't quite ready to say they've "discovered" the particle. Instead, experts familiar with the research at CERN's vast complex on the Swiss-French border say that the massive data they have obtained will essentially show the footprint of the key particle...

    Scientists at Cern will announce that the elusive Higgs boson 'God Particle' has been found at a press conference next week, it is believed. Five leading theoretical physicists have been invited to the event on Wednesday - sparking speculation that the particle has been discovered. Scientists at the Large Hadron Collider are expected to say they are 99.99 per cent certain it has been found - which is known as 'four sigma' level.

    Has the Higgs boson finally been detected? It's almost gotten to the point that if a discovery of some sort doesn't come out of next week's update on the multibillion-dollar subatomic search, it'll be a big surprise. But how far will the announcement go, and what will it mean for the future of physics? To refresh your memory, the Higgs boson is the only fundamental subatomic particle predicted by theory but not yet detected. It's thought to play a role in endowing some particles, such as the W and Z boson, with mass ... while leaving other particles, such as...

Circular Patterns in the Cosmic Microwave Background              Stephen Hawking has said: "We should look for evidence of a collision with another universe in our distant Past." Some experts believe that what we call the universe may only be one of many. Is there any conceivable way that we could ever detect and study other universes if they exist? Is it even falsifiable? This was a key question Hawking was was asked in an interview with the BBC. "Our best bet for a theory of everything...

    People often say that time speeds up as we age, but if the latest scientific theory is true the opposite could well be the case. The radical theory by academics suggests that time itself could be slowing down - and may eventually grind to a halt altogether. The latest mind-bending findings - put forward by researchers working at two Spanish universities - proposes that we have all been fooled into thinking the universe is expanding. In fact, they say, time itself is slowing down until eventually, in billions of years time, it will cease altogether. Although the findings might sound...

    Got mass? Scientists observe electrons become both heavy and speedy Electrons moving in certain solids can behave as if they are a thousand times more massive than free electrons, but at the same time act as superconductors. A new study led by Princeton scientists shows that this happens because of a process known as quantum entanglement that determines the mass of electrons moving in a crystal. The discovery can help improve understanding of how certain materials become superconducting, which may have applications in areas such as power network efficiency and computing speed.

    Two years ago several of my Sci Am colleagues and I had an intense email exchange over a period of weeks, trying to figure out what to make of a new paper by string theorist Erik Verlinde. I don’t think I’ve ever been so flummoxed by physicists’ reactions to a paper. Mathematically it could hardly have been simpler—the level of middle-school algebra for the most part. Logically and physically, it was a head-hurter. I couldn’t decide whether it was profound or trite. The theorists we consulted said they couldn’t follow it, which we took as a polite way of saying...

    Eight months after the multinational Opera research team caused an uproar among physicists with its findings that some neutrinos appeared to travel faster than light, its findings have been officially refuted. CERN, the European Organization for Nuclear Research, on Friday said that four experiments have found that neutrinos actually travel no faster than the speed of light. Opera's original measurements can be attributed to a faulty element of its experiment's fiber optic timing system, CERN said. The findings were announced at the 25th International Conference on Neutrino Physics and Astrophysics in Kyoto, Japan, by CERN research director Sergio Bertolucci. Life...

    Teleportation, sci-fi-y as it sounds, is actually not fictional or even new; two years ago, Chinese physicists broke the then-current record for quantum teleportation by teleporting photons over 10 miles. But a new effort from that same team demolishes that record, beaming the photons over 97 kilometers. The physicists, working from the University of Science and Technology of China in Shanghai, have again taken advantage of quantum entanglement for the purposes of moving an object from one place to another without ever moving in the space between. According to Technology Review, "The idea is not that the physical object is...
