    2 Futures Can Explain Time's Mysterious Past New theories suggest the big bang was not the beginning, and that we may live in the past of a parallel universe December 8, 2014 |By Lee Billings In the evolution of cosmic structure, is entropy or gravity the more dominant force? The answer to this question has deep implications for the universe's future, as well as its past. Credit: NASA; ESA; G. Illingworth, D. Magee, and P. Oesch, University of California, Santa Cruz; R. Bouwens, Leiden University; and the HUDF09 TeamPhysicists have a problem with time.   Whether through Newton’s gravitation, Maxwell’s...

    Scientists believe they have found the first evidence of the existence of other universes beyond our own, following analysis of the radiation left behind by the Big Bang. Data gathered by the European Space Agency's Planck spacecraft enabled researchers to map the "cosmic microwave" of background radiation left behind when the universe began 13.8 billion years ago. The findings imply the universe could be just one of billions, or even an infinite number, they say. The map showed anomalies that cosmologists believe could only have been caused by the gravitational pull of other universes outside our own. "These anomalies were...

    The image at bottom of page [click source link to see picture] shows the Alpha Magnetic Spectrometer-2 ("AMS-02") canister being rotated to the vertical position ready for the final lift to the launch pad, scheduled for today, Monday, the 21st of March. Sam Ting Principal Investigator for the experiment hopes that it will provide data that proves the existence of parallel universes that are composed of anti-matter --- discoveries could verify theories and answer basic questions regarding how the universe formed. "The idea of multiple universes is more than a fantastic invention --- it appears naturally within several scientific theories,...

    The signatures of a bubble collision: A collision (top left) induces a temperature modulation in the CMB temperature map (top right). The “blob” associated with the collision is identified by a large needlet response (bottom left), and the presence of an edge is determined by a large response from the edge detection algorithm (bottom right). Image credit: Feeney, et al.( -- By looking far out into space and observing what’s going on there, scientists have been led to theorize that it all started with a Big Bang, immediately followed by a brief period of super-accelerated expansion called inflation. Perhaps this...

    The strongest limit on the number of possible universes is the human ability to distinguish between different universes. ( -- Over the past few decades, the idea that our universe could be one of many alternate universes within a giant multiverse has grown from a sci-fi fantasy into a legitimate theoretical possibility. Several theories of physics and astronomy have hypothesized the existence of a multiverse made of many parallel universes. One obvious question that arises, then, is exactly how many of these parallel universes might there be. In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated...
  • Parallel Universes: Are They More Than a Figment of Our Imagination? A Galaxy Classic

    "The multiverse is no longer a model, it is a consequence of our models.” ~Aurelien Barrau, particle physicist at CERN The Hollywood blockbuster, The Golden Compass, adapted from the first volume of Pullman's classic sci-fi trilogy, "His Dark Materials" portrays various universes as only one reality among many, but how realistic is this kind of classic sci-fi plot? While it hasn’t been proven yet, many highly respected and credible scientists are now saying there’s reason to believe that parallel dimensions could very well be more than figments of our imaginations. "The idea of multiple universes is more than a fantastic...

    Black holes may harbour their own universes 15:16 31 October 2007 news service Mason Inman Black holes may contain whole universes inside them, according to a theory called loop quantum gravity (Illustration: XMM-Newton/ESA/NASA) When matter gets swallowed by a black hole, it could fall into another universe contained inside the black hole, or get trapped inside a wormhole-like connection to a second black hole, a new study suggests. What's inside a black hole is one of the biggest mysteries in physics. The theory that predicted black holes in the first place – general relativity – says that all the...

    IT HAS long been accepted, at least in theory, that other universes might exist and might even collide with ours. Yet the idea that we would ever be able to see the aftermath of such collisions, and so find evidence of other universes, has seemed beyond the scope of science. That is set to change. Anthony Aguirre of the University of California, Santa Cruz, thinks the proof of cosmic collisions could be all around us, as imprints in the cosmic microwave background (CMB) left over from the big bang. According to the standard model of cosmology, our universe underwent a...

    CLEVELAND — Cosmology used to be a heartless science, all about dark matter lost in mind-bending abysses and exploding stars. But whenever physicists and astronomers gather, the subject that roils lunch, coffee breaks or renegade cigarette breaks tends to be not dark matter or the fate of the universe. Rather it is about the role and meaning of life in the cosmos. Cosmologists held an unusual debate on the question during a recent conference, "The Future of Cosmology," at Case Western Reserve University here. According to a controversial notion known as the anthropic principle, certain otherwise baffling features of the...

    Aug. 20 — One morning last April, the New York Times op-ed page ran a piece by the Australian physicist Paul Davies warning readers not to be so gullible as to believe there could be more than one universe. The next month, Scientific American published a long article by the physicist Max Tegmark asserting that, to the contrary, parallel universes almost certainly do exist. Around the same time, bookstores received Are Universes Thicker Than Blackberries?, wherein Martin Gardner dismisses theories of multiple universes as “frivolous fantasies.” If you had seen all this, you may well have asked yourself: Is this...
