  • The Multiverse Gods, part 1 (Explaining the Origins of our Universe without Referring to God)

    The Procrustean ^ | 06/23/2011
    Victor Stenger, a retired physics prof from the University of Hawaii, has given us two books that explain both atheism and "multiverses", and behold, they are one. Few other proponents of multiverses are quite as forthcoming with their logic, but clearly something besides data must motivate the science of multiverses, because by definition multiverses are not observable. Stenger makes the connection explicit, whereas Hawking or Susskind is a little more coy with their metaphysics. Multiverse-theory is designed for one purpose, and one purpose only, and that is to defend atheism. It makes no predictions, it gives no insight, it provides...

    Astronomers have found a nascent star 750 light years from earth that shoots colossal jets of water -- a cosmic fire hose -- out its poles in bullet-like pulses. In a process that almost defies adjectives and analogies, each jet of water is the equivalent of a hundred million times the water flowing through the Amazon River every second and the speed of the jet is the equivalent of 80 times the muzzle velocity of an AK-47 assault rifle. The blast creates huge shockwaves around the star and the process may be responsible for sprinkling the universe with water. And...

    Is an Adjacent Universe Causing the Dark Flow of Hundred of Millions of Stars at the Edge of the Observable Universe? Or, Might It Be Something ElseBack in the Middle Ages, maps showed terrifying images of sea dragons at the boundaries of the known world. Today, scientists have observed strange new motion at the very limits of the known universe -- kind of where you'd expect to find new things, but they still didn't expect this. A huge swathe of galactic clusters seem to be heading to a cosmic hotspot and nobody knows why. The unexplained motion has hundreds of...

    That's scientists' latest estimate for our galaxy alone, based on Kepler data Roughly one out of every 37 to one out of every 70 sunlike stars in the sky might harbor an alien Earth, a new study reveals. These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added. These new calculations are based on data from the Kepler space telescope, which in February wowed the globe by revealing more than 1,200 possible alien worlds, including 68 potentially Earth-size planets. The spacecraft does so by looking for the dimming that occurs when a world transits or...
  • Once Upon a Time, the Universe Was Really Weird

    Today, looking out across a seemingly boundless cosmos filled with an unimaginable variety of exotic objects, it's easy to forget that the Universe we currently admire is the product of a violent event that occurred 13.75 billion years ago. As we know, the leading theory for universal birth is the Big Bang, where everything came from nothing, in a single energetic burst of inexplicable creation. So, if we turn back the clock back 13.75 billion years, what would we see? My instinct would be to say "energy, the Universe was filled with pure, violent energy," but according to some mind-bending...
  • Are We One of Many Universes? MIT Physicist Says "Yes"

    Modern cosmology theory holds that our universe may be just one in a vast collection of universes known as the multiverse. MIT physicist Alan Guth has suggested that new universes (known as “pocket universes”) are constantly being created, but they cannot be seen from our universe. In this view, “nature gets a lot of tries — the universe is an experiment that’s repeated over and over again, each time with slightly different physical laws, or even vastly different physical laws,” says Jaffe. Some of these universes would collapse instants after forming; in others, the forces between particles would be so...

    Our Universe is an enormous place; that’s no secret. What is up for discussion, however, is just how enormous it is. And new research suggests it’s a whopper – over 250 times the size of our observable universe. Currently, cosmologists believe the Universe takes one of three possible shapes: It is flat, like a Euclidean plane, and spatially infinite.It is open, or curved like a saddle, and spatially infinite.It is closed, or curved like a sphere, and spatially finite. While most current data favors a flat universe, cosmologists have yet to come to a consensus. In a paper recently submitted...

    Howard Smith, a senior astrophysicist at Harvard, made the claim that we are alone in the universe after an analysis of the 500 planets discovered so far showed all were hostile to life. Dr Smith said the extreme conditions found so far on planets discovered outside out Solar System are likely to be the norm, and that the hospitable conditions on Earth could be unique. “We have found that most other planets and solar systems are wildly different from our own. They are very hostile to life as we know it,” he said. He pointed to stars such as HD10180,...

    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.

    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...

In a chaotic system, small changes can cause large-scale effects.

    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...
