    Muons unveiled new details about a void in Egypt’s Great Pyramid

    The subatomic particles revealed the dimensions of the void, discovered in 2016, and helped researchers know where to stick a camera inside.

    The standard model of particle physics passed one of its strictest tests yet

    An experiment with a single electron, trapped for months on end, produced one of the most precise tests yet of the standard model of particle physics.

    50 years ago, physicists found the speed of light

    In the 1970s, scientists set a new maximum speed limit for light. Fifty years later, they continue putting light through its paces.

    How ghostly neutrinos could explain the universe’s matter mystery

    If neutrinos behave differently from their antimatter counterparts, it could help explain why our cosmos is full of stuff.

    50 years ago, physicists got a whiff of what glues together protons

    In 1972, particle smashups hinted at the gluon, which we now know not only holds together the innards of the proton, but also makes up more than a third of its mass.

    Protons contain intrinsic charm quarks, a new study suggests

    The massive quarks — counterintuitively heavier than the proton itself — might carry about 0.6 percent of a proton’s momentum.

    Physicists spotted rare W boson trios at the Large Hadron Collider

    By measuring how often triplets of particles called W bosons appear, scientists can check physics’ standard model for any cracks.

    The Windchime experiment could use gravity to hunt for dark matter ‘wind’

    Though decades away, the project hopes to use an array of ultrasensitive sensors as a “wind chime,” jostled by dark matter blowing past Earth.

    A new dark matter experiment quashed earlier hints of new particles

    Unlike its earlier incarnation, the XENONnT detector found no evidence of extra blips that scientists had hoped indicated new physics.

    A supersensitive dark matter search found no signs of the substance — yet

    The LZ experiment’s first measurement raises hopes that scientists are closer than ever to finding the source of much of the universe’s mass.
