    The Tevatron may be shut down for good, but – as evidenced by the catalogue of results presented at this week’s Rencontres de Moriond conference – the collider’s experiments still have plenty to say. In some areas, the Fermilab experiments still hold the advantage over those at the higher-powered Large Hadron Collider at CERN.

  • Why we've got the cosmological constant all wrong

    Updated: 2012-03-05 13:20:01
    (PhysOrg.com) -- Some scientists call the cosmological constant the "worst prediction of physics." And when today’s theories give an estimated value that is about 120 orders of magnitude larger than the measured value, it’s hard to argue with that title. In a new study, a team of physicists has taken a different view of the cosmological constant, Λ, which drives the accelerated expansion of the universe. While the cosmological constant is usually interpreted as a vacuum energy, here the physicists provide evidence to support the possibility that the mysterious force instead emerges from a microscopic quantum theory of gravity, which is currently beyond physicists’ reach.
