    Best Art in the Universe? Hubble Space Telescope's Amazing Pics From 2010 (Dec. 15) -- You might think that taking highly detailed photographs of the darkest corners of the universe would be a purely scientific job. Turns out, there's an art to it. For the past 20 years, the Hubble Space Telescope has been orbiting the planet and wowing earthlings with breathtaking images of outer space, from jaw-dropping pictures of clusters of newborn stars to fantastic photos of colliding galaxies. But it's not just Hubble's cutting-edge optics that are responsible for these stunning photographs. Behind each image is the hard...

    Latest research deflates the idea that the Universe cycles for eternity.Our view of the early Universe may be full of mysterious circles — and even triangles — but that doesn't mean we're seeing evidence of events that took place before the Big Bang. So says a trio of papers taking aim at a recent claim that concentric rings of uniform temperature within the cosmic microwave background — the radiation left over from the Big Bang — might, in fact, be the signatures of black holes colliding in a previous cosmic 'aeon' that existed before our Universe.
  • 300 Sextillion Stars in Universe, New Study Suggests

    The night sky may be a lot starrier than we thought. A study suggests the universe could have triple the number of stars scientists previously calculated. The new estimate is 300,000,000,000,000,000,000,000. That's 300 sextillion. The study questions a key assumption that astronomers often use: that most galaxies have the same properties as our Milky Way. And that's creating a bit of a stink among astronomers who want a more orderly cosmos.

    Have we found the universe that existed before the Big Bang? The current cosmological consensus is that the universe began 13.7 billion years ago with the Big Bang. But a legendary physicist says he's found the first evidence of an eternal, cyclic cosmos. The Big Bang model holds that everything that now comprises the universe was once concentrated in a single point of near-infinite density. Before this singularity exploded and the universe began, there was absolutely nothing - indeed, it's not clear whether one can even use the term "before" in reference to a pre-Big-Bang cosmos, as time itself may...

    If you "lived inside" a hologram, you could tell by measuring the blurring. Fermilab is building a interferometer to test space time for holographic blurring. Possible consequence of holography Hypothesis: observable correlations are encoded on light sheets and limited by information capacity of a Planck wavelength carrier (“Planck information flux” limit) Predicts uncertainty in position at Planck diffraction scale

    <p>The universe was in chaos after the Big Bang kick-started the cosmos, a new study suggests.</p> <p>While one might expect the explosion that began the universe to wreak some havoc, scientists mean something very specific when they refer to chaos. In a chaotic system, small changes can cause large-scale effects. A commonly cited example is the "butterfly effect" — the idea that a butterfly beating its wing in Brazil can bring about a tornado in Texas.</p>

    Has physics done away with God? A newly release book by Stephen Hawking and Leonard Mlodinow says, “Yes.” What is a Jewish or Christian believer to make of this? Is the Creator now out of a job? The short answer is (unsurprisingly) no: the ideas propounded in Hawking’s book constitute no threat whatever to the Jewish and Christian doctrine of Creation. The idea that Hawking is now touting is not new—in fact, within the fast-moving world of modern physics it is fairly old. My first introduction to it was reading a very elegant theoretical paper entitled “Creation of Universes from...

    Could the elusive Higgs boson finally be in sight? Earlier this summer, physicist Tommaso Dorigo of the University of Padua wrote about talk of a tentative hint of the Higgs at the Tevatron, a particle accelerator at the Fermi National Accelerator Laboratory in Batavia, Illinois. "It reached my ear, from two different, possibly independent sources, that an experiment at the Tevatron is about to release some evidence of a light Higgs boson signal. Some say a three-sigma effect, others do not make explicit claims but talk of a unexpected result," wrote Dorigo. The blog post was low on detail but...

    There's no denying that Stephen Hawking is intellectually bold as well as physically heroic. And in his latest book, the renowned physicist mounts an audacious challenge to the traditional religious belief in the divine creation of the universe. According to Hawking, the laws of physics, not the will of God, provide the real explanation as to how life on Earth came into being. The Big Bang, he argues, was the inevitable consequence of these laws 'because there is a law such as gravity, the universe can and will create itself from nothing.' Unfortunately, while Hawking's argument is being hailed as...

    God did not create the universe, world-famous physicist Stephen Hawking argues in a new book that aims to banish a divine creator from physics.Hawking says in his book "The Grand Design" that, given the existence of gravity, "the universe can and will create itself from nothing," according to an excerpt published Thursday in The Times of London."Spontaneous creation is the reason why there is something rather than nothing, why the universe exists, why we exist," he writes in the excerpt."It is not necessary to invoke God to light the blue touch paper [fuse] and set the universe going," he...

    RICHARD FEYNMAN, Nobel laureate and physicist extraordinaire, called it a “magic number” and its value “one of the greatest damn mysteries of physics”. The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen atoms. One consequence would be that squishy, carbon-based life would not exist. Why alpha takes on the precise value it does, so delicately fine-tuned for...

    A "galactic lens" has revealed that the Universe will probably expand forever. Astronomers used the way that light from distant stars was distorted by a huge galactic cluster known as Abell 1689 to work out the amount of dark energy in the cosmos. Dark energy is a mysterious force that speeds up the expansion of the Universe. Understanding the distribution of this force revealed that the likely fate of the Universe was to keep on expanding. It will eventually become a cold, dead wasteland, researchers say. The study, conducted by an international team led by Professor Eric Jullo of Nasa's...

    HD 209458b, shown in red in an artist's conception, is the first confirmed "cometary planet," experts say. Image courtesy G. Bacon, NASA/ESAAn alien planet orbits so close to its star that its atmosphere is being blasted away, forming a gaseous, comet-like tail, astronomers announced Thursday. (Related: "Odd Star Sheds Comet-like Tail.") About 153 light-years from Earth, planet HD 209458b hugs its star so tightly that the planet's atmosphere is likely a scorching 2,000 degrees Fahrenheit (1,093 degrees Celsius) an a year passes in just 3.5 days—making Mercury's 88-day orbit seem downright leisurely.That tight orbit also means this gas giant—meaning...

    A radical reformulation of quantum mechanics suggests that the universe has a set destiny and its pre-existing fate reaches back in time to influence the past. It could explain the origin of life, dark energy and solve other cosmic conundrums.The universe has a destiny—and this set fate could be reaching backwards in time and combining with influences from the past to shape the present. It’s a mind-bending claim, but some cosmologists now believe that a radical reformulation of quantum mechanics in which the future can affect the past could solve some of the universe’s biggest mysteries, including how life arose....

    Physicists have long wondered why the universe exists when matter and anti-matter particles obliterate each other on contact. But new data from a particle accelerator in the United States suggests a reason. The tests showed that when anti-protons and protons collide, the resulting new particles show a one per cent skew toward matter over anti-matter. Over a long period of time, this characteristic of the universe could explain why matter has come to dominate over anti-matter. "Many of us felt goose bumps when we saw the result," said Stefan Soldner-Rembold, a physicist at the University of Manchester in the United...

    According to my psychoanalyst, I have issues. She believes our nation's dichotomous political climate and divisive political dialogue is affecting my mental state and I'm beginning to show a "disconnect." It's disconcerting to confess that you're coming unhinged -- to admit you're losing touch with reality and are living in some loony parallel universe. Just this month, famed astrophysicist Stephen Hawking expressed his belief that humans are capable of time travel. No kidding. Welcome to my world. My therapist says my anger issues are revealing, but it's not a personality disorder that's got me. It's not an addictive disorder because...

    A supermassive black hole sits inside the galaxy Centaurus A, seen in an artist's conception. Like part of a cosmic Russian doll, our universe may be nested inside a black hole that is itself part of a larger universe.In turn, all the black holes found so far in our universe—from the microscopic to the supermassive—may be doorways into alternate realities.According to a mind-bending new theory, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole"...

    Scientists celebrated at the world's biggest atom smasher at the European Organization for Nuclear Research (CERN) near Geneva on Tuesday as they started colliding particles at record energy levels mimicking conditions close to the Big Bang, opening a new era in the quest for the secrets of the universe. The European Organisation for Nuclear Research (CERN) said it had unleashed the unprecedented bursts of energy on the third attempt, as beams of protons thrust around the 27-kilometre (16.8-mile) accelerator collided at close to the speed of light. "This is physics in the making, the beginning of a new era, we...
