    A group of Penn State physicists says the universe we now see could have arisen from a "Big Bounce" rather than a Big Bang. The new work by Penn State, led by professor Abhay Ashtekar, director of the Institute for Gravitation and the Cosmos, proposes ways to apply quantum physics "further back in time than ever before – right back to the beginning," the university says in a release. We have a pretty good idea of the large-scale structures of the universe when it was only a few hundred thousand years old. That comes from studying the fingerprint of the...

    A team at the Max Planck Institute for Astronomy has found the largest recorded black hole, one that swallows an unprecedented amount of its home galaxy, potentially requiring a rethink in our understanding of galactic formation. The huge hole has been spotted in the heart of the disk system NGC 1277, a smallish galaxy about 10 per cent of the size of the Milky Way and situated around 220 million light-years from Earth, in the constellation Perseus. Almost all galaxies have black holes at their centers, but they typically only take up around 0.1 per cent of the total galactic...

    The first steps towards interstellar travel have been taken, but the stars are very far away. Voyager 1 is about 17 light-hours distant from Earth and is traveling with a velocity of 0.006 percent of light speed, meaning it will take about 17,000 years to travel one light-year. Fortunately, the elusive "warp drive" now appears to be evolving past difficulties with new theoretical advances and a NASA test rig under development to measure artificially generated warping of space-time. The warp drive broke away from being a wholly fictional concept in 1994, when physicist Miguel Alcubierre suggested that faster-than-light (FTL) travel...

    Credit: CERN Still too soon to know. That's the latest word from particle physicists working with the world's largest atom smasher—Europe's Large Hadron Collider in Switzerland—as they try to figure out whether the particle they discovered in July is precisely the long-sought Higgs boson or something a tad different. The key question is whether the new particle decays into combinations of familiar particles at the rates that physicists' standard model predicts. So far, the measured decay rates generally match expectations, but the statistical uncertainties are too large to say anything conclusive, physicists working with the gargantuan particle detectors known...

    LONDON (Reuters) - An international team of astronomers has produced the first map of the universe as it was 11 billion years ago, filling a gap between the Big Bang and the rapid expansion that followed. The study, published in the journal Astronomy & Astrophysics, shows the universe went through a phase roughly three billion years after the Big Bang when expansion actually started to slow, before the force of so-called 'dark energy' kicked in and sent galaxies accelerating away from each other. Much is known about the immediate aftermath of the Big Bang from studies of its afterglow in...

El Reg has no possible hope of fully understanding this paper (published in full, an emerging trend we welcome), but one really interesting idea is right there in the abstract: “We anticipate similar spontaneous knot topology to be a universal feature of waves whose phase front is twisted and nonlinearly modulated, including superfluids and trapped matter waves.” [Emphasis added] In other words, this research has the potential to be replicated...

    (Phys.org)—David Ruffner and David Grier of New York University have developed a technique for using Bessel beams to draw a particle toward a source. In their paper published in Physical Review Letters they describe how they used their technique to pull 30 micrometer sized silica spheres suspended in water, towards a laser source. A device that uses energy to pull an object towards a source is known as a "tractor beam" after the fictional technology of Star Trek fame. To date no such device exists, but this new work by Ruffner and Grier shows that it might be possible. Their...

    One of the most deeply rooted concepts in science and in our everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. If an event A is a cause of an effect B, then B cannot be a cause of A. Now theoretical physicists from the University of Vienna and the Université Libre de Bruxelles have shown that in quantum mechanics it is possible to conceive situations in which a single event can be both, a cause and an effect...

    A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say. A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy. Now physicists say that adjustments can be made to the proposed warp drive that would...

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...

    Tevatron presents strong evidence Higgs boson was observed, but LHC needed to provide final verificationTomorrow, while America celebrates July 4, mankind worldwide may celebrate a separate momentous event -- the discovery of the legendary Higgs boson. I. Riding Into the Sunset -- Tevatron Goes Out With a Bang The European Organization for Nuclear Research (CERN) will tomorrow hold a special press conference at 9 a.m.  The event will provide an update to the world on the progress in the search for the critical particle using the Large Hadron Collider, the largest and most expensive laboratory apparatus in history.  Many physicists...

    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...

    A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun. Excellent video on the science of our magnetosphere and how we are just learning about field reversal that open and close between earth and the sun.
