    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...

    Darwin's God ^ | 03/15/2010 | Cornelius Hunter
    You have probably heard about the multiverse--the idea that the universe is really a large number of universes. The multiverse helps to explain why our particular universe seems so special. Our universe seems to be a finely tuned machine and the evolution of life would require low probability events. Is our universe special? The multiverse helps to deflect such thinking. If there is a large number of universes, then perhaps each has a different set of natural laws. And perhaps intelligent life can only be supported by a very particular set of laws. So the only life forms that would...

    GENEVA (Reuters) – Dark matter, which scientists believe makes up 25 percent of the universe but whose existence has never been proven, could be detected by the giant particle collider at CERN, the research center's head said Monday. Rolf-Dieter Heuer told a news conference some evidence for the matter may emerge even in the shorter term from mega-power particle collisions aimed at recreating conditions at the "Big Bang" birth of the universe some 13.7 billion years ago. "We don't know what dark matter is," said Heuer, Director-General of the European Organization for Nuclear Research on the Swiss-French border near Geneva....

    Atom smashers at a U.S. national lab have produced temperatures not seen since the Big Bang — 7.2 trillion degrees, or 250,000 times hotter than the sun's interior — in work re-creating the universe's first microseconds. The results come from the 2.4-mile-wide Relativistic Heavy Ion Collider at the Department of Energy's Brookhaven (N.Y.) National Laboratory. Since 2000, scientists there have hurtled gold atoms together at nearly the speed of light. These smash-ups heat bubbles smaller than the center of an atom to about 40 times hotter than the center of an imploding supernova. Scientists say the results have given them...

    When a Russian Cosmonaut returned from a space flight he said that he hadn’t seen God out there. An American Astronaut, one who was a Christian, was once asked if he had met God while in space. He answered with full confidence, “I would have, if I had taken off my space suit.” These are not just two contradictory answers to the same question. They are two totally different understandings of the word God and what is meant by it. The Russian Cosmonaut, an atheist, could not believe God existed unless he saw him with his own eyes. Whereas the...

    WASHINGTON – NASA's new planet-hunting telescope has found two mystery objects that are too hot to be planets and too small to be stars. The Kepler Telescope, launched in March, discovered the two new heavenly bodies, each circling its own star. Telescope chief scientist Bill Borucki of NASA said the objects are thousands of degrees hotter than the stars they circle. That means they probably aren't planets. They are bigger and hotter than planets in our solar system, including dwarf planets. "The universe keeps making strange things stranger than we can think of in our imagination," said Jon Morse, head...

    NASA's Hubble Space Telescope has reached back 13.2 billion years -- farther than ever before in time and space -- to reveal a "primordial population" of galaxies never seen before. "The deeper Hubble looks into space, the farther back in time it looks, because light takes billions of years to cross the observable universe," the Space Telescope Science Institute said in a statement released Tuesday. "This makes Hubble a powerful 'time machine' that allows astronomers to see galaxies as they were 13 billion years ago -- just 600 million to 800 million years after the Big Bang," the institute said...

    "Everyone loves a good road movie, whether it's Hope and Crosby or Fonda and Hopper. But the scope of those films pales in comparison to the ground covered by the Hayden Planetarium's new video, The Known Universe. The video starts in Tibet and zooms out through time and space until it shows well, the entire known universe. The video, created for the new Rubin Art Museum exhibit Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, uses over a decade of data collected by researchers at the planetarium. Called the Digital Universe Atlas, the data encompasses the...

    The typical Hollywood action hero skirts death for a living. Time and again, scores of bad guys shoot at him from multiple directions but miss by a hair. Cars explode just a fraction of a second too late for the fireball to catch him before he finds cover. And friends come to the rescue just before a villain’s knife slits his throat. If any one of those things happened just a little differently, the hero would be hasta la vista, baby. Yet even if we have not seen the movie before, something tells us that he will make it to...
  • Why Evolutionary-Based Science Is A Menace To Scientific Research, Discovery, and Progress

    Why Evolutionary-Based Science Is A Menace To Scientific Research, Discovery, and Progress Evolutionary-based research always begins with the inaccurate and unscientific presupposition that the Theory of Evolution, i.e. the Big Bang, the spontaneous generation of life, and common descent, is true. Due to this systemic problem, scientific discovery and progress is severely hampered, not to mention the hundreds of millions of research dollars that are squandered every year. In a time in which almost ANY alternative thought is given a platform, the evolution industry is silencing dissenting scientific evidence, even when it’s from fellow evolutionists! See the growing list of...

    A gigantic, previously unknown set of galaxies has been found in the distant universe, shedding light on the underlying skeleton of the cosmos. "Matter is not distributed uniformly in the universe," said Masayuki Tanaka, an astronomer with the European Southern Observatory (ESO) who helped discover the galactic assemblage. "In our cosmic vicinity, stars form in galaxies and galaxies usually form groups and clusters of galaxies." But those collections of matter are just small potatoes compared to larger structures long-theorized to exist. "The most widely accepted cosmological theories predict that matter also clumps on a larger scale in the so-called 'cosmic...
