    7 Major Experiments That Still Haven’t Found What They’re Looking For

    Being an experimental scientist can sometimes seem like a thankless task. You may be used to reading headlines about experiments that end up making great discoveries, but less is heard about the (often heroic) efforts of experimentalists that have yet to detect or observe what they set out to. Some of these efforts have spanned […]

    Excitement Over Gravity Waves Comes Crashing Down

    The Dark Sector Lab includes the BICEP2 telescope, seen on the left.BICEP Keck Science giveth, and science taketh away. What appeared earlier this year to be a long-sought glimpse of ancient ripples in spacetime now seems to have been schmutz in astronomers’ eyes. In March, sky-gazers using a telescope at the South Pole called BICEP2 […]

    Is Our Universe Like Oil & Vinegar or Homogenized Milk?

    Is our Universe inhomogeneous, lumpy and uneven on many size scales, like oil droplets in water?via Shutterstock   In the earliest moments after the Big Bang, the Universe was a turbulent mess, a high-temperature stew of quantum fluctuations. As with turbulence in water, the fluctuations acted at every level: If you could imagine observing the […]

    The Father of Inflation Clears Up a Big Misunderstanding

    Last week researchers working on the BICEP2 experiment in Antarctica announced that they’d seen solid evidence of gravitational waves that emerged very early in the Universe’s history. This discovery lent support to inflation, a theory of cosmology long popular among physicists but still lacking in direct proof. (To learn more about the recent discovery and […]

    Over the Universe—The Best Reactions to the Big Physics News

    These swirls in the cosmic microwave background show the effect of primordial gravitational waves.BICEP2 Scientists, on the whole, are a circumspect lot. When faced with a microphone or reporter’s notepad, most of them (excepting a vocal minority) hedge and temper their language, adding provisos and qualifications, burying significant news behind accurate but unexciting jargon. So […]
